Description

  The present invention relates to a data backup device (external storage device) and a data backup system for backing up data stored in a portable device (mobile terminal). The present invention also relates to a data backup method for backing up data stored in a mobile terminal. Furthermore, the present invention relates to a data restoration method for restoring backed up data to a mobile terminal.

  In recent years, in mobile terminals (particularly mobile phones), it has become possible to store a wide variety of data in a storage device in the mobile phone. For example, phone book and schedule book data written by the user of the mobile phone can be stored electronically in the mobile phone. In addition, photographic images taken with a camera mounted on a mobile phone and contents such as music or games obtained through an online service can be stored electronically in the mobile phone. Furthermore, electronic coupon tickets and tickets can be electronically stored in the mobile phone using near field communication such as infrared rays or FeliCa (registered trademark).

  As described above, a large amount of data that is important as personal information and also important as a monetary value is accumulated on one mobile terminal. Therefore, when the mobile terminal breaks down or is lost, loss due to loss of data is also large. Therefore, it is desirable to back up the data in the portable terminal that is carried on a daily basis as frequently as possible.

  As a backup means currently provided, for example, a personal computer (hereinafter also simply referred to as a PC) and dedicated application software for backup processing (hereinafter also referred to as a dedicated AP) store the portable terminal. There is a way to back up data. In addition, there is a method of backing up data stored in the portable terminal to the PC side by connecting the portable terminal and the PC with a cable or performing infrared communication between the portable terminal and the PC. In addition, an external memory card that can be directly attached to a mobile terminal is attached to the mobile terminal so that only some types of data (for example, phone book data, images, and voice data) can be stored in the memory card. Has been done.

  When a backup means using a PC and a dedicated AP is used, it is possible to back up a relatively large number of types of data. However, a series of procedures such as starting up a PC, connecting a portable terminal and a PC, or starting up a dedicated AP is required for backup. For this reason, the work is complicated for the user, and it is not easy to make the user routinely perform backup.

  Even when a failure such as a failure or loss of the mobile terminal occurs, there is a case where it is desired to change the mobile phone to a new model, for example. In this case, even if the data migration means (apparatus) provided in the mobile phone sales store is used, all the original data (for example, all types of data) currently stored in the mobile phone are transferred to the new mobile phone. Cannot be transferred to.

  Further, for example, Patent Document 1 describes means for easily backing up image data stored in an imaging apparatus such as a digital still camera that is a kind of portable terminal. In the method described in Patent Document 1, a backup external storage device is provided on a charging base of an imaging device generally called a cradle so that data can be backed up at the time of charging. If the backup means described in Patent Document 1 is used, it is simpler than the backup method using a PC. Further, since it generally takes 1 hour or more for charging, even when there is a large amount of data to be backed up, a sufficient time for backup can be secured. That is, the backup method described in Patent Document 1 has an advantage that it is not necessary to secure a long time for fixing the portable terminal for backup separately from charging.

  On the other hand, simply providing a means for facilitating backup work enables backup and restoration to the same backup device, regardless of who owns the same model of mobile terminal. It can be done. For this reason, there is a problem that data having different contents with the same file name may be overwritten, or that other users than authorized users can easily share commercially available content that is not permitted to be copied without permission.

  On the other hand, Patent Literature 2 describes a method of restricting data restoration by a terminal of a user other than a regular user. In the method described in Patent Document 2, when a JAVA (registered trademark) application is backed up from a mobile phone to a PC, the manufacturing number and the telephone number of the mobile phone are recorded. Further, when restoring data, the recorded production number and telephone number are compared with the production number and telephone number acquired from the restoration destination mobile phone. If the manufacturing number and telephone number do not match, the data is not restored.

  When the method described in Patent Document 2 is used, when content whose usage count is limited is backed up, the content is backed up for each counter that records the usage count of the content. Therefore, when one or both of the manufacturing number and the telephone number of the mobile phone match, the content can be restored any number of times. Therefore, there arises a problem that the content with the use frequency limit can be used practically any number of times. To deal with such problems, Non-Patent Document 1 can back up content with a limited number of uses, but the server manages the number of uses by inquiring to a dedicated server when restoring to the original terminal. It describes how to prevent use more than the specified number of times.

  In the conventional data backup device described in Patent Literature 1, Patent Literature 2, and Patent Literature 3, it is necessary to connect to the data backup device when exchanging a portable terminal with another new portable terminal. The connector shape may differ between the old model and the new model. In addition, when using the data backup device described in Patent Document 1, the rated value of voltage and frequency may be different between the mobile terminal before replacement and the mobile terminal after replacement. If they are integrated, the data backup device must be replaced after all. Therefore, there are cases where data cannot be transferred from the original terminal before the exchange to the new terminal even though the users are the same.

  Note that Patent Document 1 also describes a method of using wireless communication for data transmission for backup. However, even if data is transmitted by wireless communication, it can be used on the portable terminal side and the backup device side, for example, when an infrared communication method is adopted on the portable terminal side and Bluetooth is adopted on the backup device side. If different wireless communication systems are different, backup cannot be performed. Moreover, in patent document 1, although the simple means for backing up the data in a portable terminal is provided, when changing a portable terminal to the portable terminal of another different new model, after changing backed up data No means is disclosed that can be reliably restored in the mobile terminal.

  Also, if the owner of the mobile device himself restores the data by buying his own mobile device with another mobile device, but restoring the backed up data to a mobile device different from the backup source, An illegal copy was made. In addition, if illegal copying is performed, copyright infringement may occur. Therefore, it is desirable that the backup device includes means for preventing unauthorized copying.

  Patent Document 2 discloses a method of permitting restoration of backup data to a different terminal only at the time of replacement of the terminal by the owner of the portable terminal. However, the method described in Patent Document 2 requires special implementation for realizing the backup function and the restoration function in both the portable terminal and the backup device. Further, in the method described in Patent Document 2, since the ID information of the mobile terminal is recorded on the backup device side, the backup device is required to have high tamper resistance. For this reason, the method described in Patent Document 2 increases the cost of manufacturing a backup device and the like in order to realize the above functions. Therefore, it is desired to realize the backup device at a lower cost.

  Therefore, an object of the present invention is to provide a data backup device, a data backup system, a data backup method, and a data restoration method that can back up data stored in the portable terminal regardless of the model of the portable terminal. The present invention also provides a data backup device, a data backup system, a data backup method, and a data backup device that can easily back up data stored in a portable terminal on a daily basis and can easily restore data using simple means when necessary. An object is to provide a data restoration method.

  In addition, the present invention provides a data backup that can restore backup data using simple means only for a single portable terminal after changing the terminal when the terminal is changed due to a failure, loss, replacement by purchase, etc. An object is to provide an apparatus, a data backup method, and a data restoration method.

  A data backup method according to the present invention is a data backup method for backing up data stored in a portable terminal, wherein the data backup device connected to the portable terminal via the charging device of the portable terminal is portable via the charging device. The step of reading the data stored in the terminal and the step of the data backup device writing the read data to the data storage means are characterized.

And a step of writing the read data to the portable terminal via the charging device.

  According to this invention, in order to back up the data which a portable terminal memorize | stores using a data backup apparatus, it comprises so that a data backup apparatus and a portable terminal may be connected via a charging device. Therefore, the shape and specification of the connection part between the data backup device and the charging device can be made common regardless of the model of the portable terminal. Therefore, the data stored in the mobile terminal can be backed up regardless of the model of the mobile terminal.

  Further, according to the present invention, data backup can be performed while the mobile terminal is being charged simply by placing the mobile terminal on the charging device. This eliminates the need for the user to perform special work for backup. Also, by using a sufficiently long charging time, the user can be made unaware of the waiting time for backup. Further, differences in the shapes and voltage values of the charging terminal and the data transfer terminal that may be different for each portable terminal can be absorbed through the charging device. Therefore, the charging device and the data backup device can be designed independently of the design of the mobile terminal (for example, the design of the terminal shape) while maintaining a high degree of freedom in the design of the mobile terminal.

  Further, in the present invention, control may be performed so that the backup data is restored only to the backup source mobile terminal, even if the backup data is restored to a mobile terminal different from the backup source mobile terminal. In addition, control may be performed so that data cannot be restored to a terminal other than the terminal in which the terminal ID and the dedicated backup ID are transferred from the backup source portable terminal. Moreover, if the backup ID is generated based on the terminal ID of the portable terminal and the device ID of the data backup device, it is difficult to falsify the backup ID. In addition, although it is a simple mechanism, it is possible to prevent unauthorized copying of backup data.

  In the present invention, if the backup ID is used, the data backup device can identify the portable terminal. Further, it is possible to eliminate the need for the data backup device itself to store the terminal ID of the portable terminal. Therefore, if the data backup device backs up the data to the data storage means, it is possible to prevent the terminal ID and backup ID of the portable terminal from being read even if the tamper resistance of the data backup device itself is low. . Further, it is possible to eliminate the necessity of providing a special function for backup and restoration on the portable terminal side.

  In the present invention, if the data backup device is provided with data storage means, the mobile terminal can be configured to be lighter than when the mobile terminal is provided with data storage means. Moreover, the risk of losing the portable terminal together with the backup data can be eliminated.

  In the present invention, backup may be permitted only when the privacy information of the user of the mobile terminal includes more than a predetermined amount of data in the data stored in the mobile terminal. Further, the privacy information and the paid content may be restored without being divided. The data restoration may be permitted again only when a sufficient time has elapsed after the data restoration. By doing so, it is possible to prevent illegal copying of paid content using the data backup device.

Embodiment 1 FIG.
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing a hardware configuration when performing data backup and restoration using a data backup device according to the present invention. As shown in FIG. 1, in this embodiment, a charging device 2 is connected to a data backup device 1 and a portable terminal 3 is attached to the charging device 2. That is, in this embodiment, the data backup device 1 is connected to the mobile terminal 3 via the charging device 2. In the present embodiment, a data backup system that backs up data stored in the mobile terminal 3 is realized by the data backup device 1, the charging device 2, and the mobile terminal 3.

  First, in order to facilitate understanding of a data backup method and a data restoration method using the data backup device 1 shown in FIG. 1, a case where data backup or restoration is performed based on a similar conventional technique will be described. FIG. 2 is an explanatory diagram showing a hardware configuration when performing backup and restoration of data based on the prior art.

  As shown in FIG. 2, when backing up data stored in a portable terminal based on the prior art, first, the portable terminal 93 is connected to a personal computer 94 via a connection cable 95. Then, backup processing is performed using application software 96 operating on the personal computer 94.

  As another backup means, backup can be performed by attaching an external storage medium (for example, SD memory card or Memory Stick (registered trademark)) to the portable terminal. In this case, specific types of data (for example, phone book data, images, and audio data) in the portable terminal are transferred to a personal computer or external storage device equipped with a memory card reader / writer using these external storage media. Make a copy. However, when these backup means are used, it is necessary to perform an operation for connecting the portable terminal to another device or an external storage medium or a manual backup operation, which takes time for the user.

  As a device that can perform the backup process according to the conventional method shown in FIG. 2, a product that can charge the portable terminal 93 together with the backup process using a connection cable 95 is commercially available. However, in general, a product that can be charged together with such a backup uses a connection means with a low power supply capability, such as a USB cable, as the connection cable 95. Therefore, it takes time to charge compared to the case of using a charging means dedicated to the portable terminal.

  As a method for efficiently charging the mobile terminal, there is a method of charging by attaching a cable dedicated to each mobile terminal equipped with an AC adapter to the mobile terminal itself. Further, recently, a pedestal (generally called a cradle) that can be charged only by placing a mobile terminal is sold along with each mobile terminal, or sold separately from the mobile terminal.

  When a charging cradle is provided with a backup function for data in a portable terminal (see, for example, Patent Document 1), in general, the position of the charging terminal provided in the portable terminal, the shape around the terminal, and the voltage value for charging Etc. differ depending on each portable terminal. Therefore, when the cradle is provided with a backup function, it is necessary to prepare a cradle having both a charging function and a backup function for each type of portable terminal. In general, the shape of a mobile terminal changes frequently due to advances in functions and technology of the mobile terminal, changes in consumer needs, and the like. For this reason, it is not a good idea to incorporate a backup function including an expensive external storage device or control circuit into a cradle that is directly connected to the portable terminal.

  On the other hand, when data stored in the mobile terminal 3 is backed up using the data backup device 1 shown in FIG. 1, the data backup device 1 is connected to the mobile terminal 3 via the charging device 2. As shown in FIG. 1, in the present embodiment, the charging device 2 includes a power outlet 21, and the data backup device 1 is supplied with power from the charging device 2. As shown in FIG. 1, in this embodiment, the data backup device 1 can be loaded with an external storage medium 13A (for example, an SD memory card). Then, by replacing the external storage medium 13A attached to the data backup device 1, the data stored in the mobile terminal 3 can be backed up many times, or the data of another mobile terminal 3 can be backed up.

  As shown in FIG. 1, in the present embodiment, the shape of the charging device 2 is matched with the shape of each mobile terminal (for example, the shape of the connection terminal), and the shape of the connection terminal of the charging device 2 is changed to that of the data backup device 1. It is necessary to match the shape of the connection terminal. Here, the charging device 2 only needs to have wiring and connection terminals for supplying power to the mobile terminal 3 and the data backup device 1 respectively. Further, the charging device 2 only needs to have wiring and connection terminals for transferring data between the portable terminal 3 and the data backup device 1. Therefore, the charging device 2 is less restricted in appearance design and can be produced at a low cost independently of the data backup device 1. With such a configuration, the charging device 2 used for the portable terminal 3 can be provided as an accessory of the portable terminal 3 or as an optional option that can be sold separately, similarly to the conventional charging device.

  In the present embodiment, the charging device 2 is manufactured as a dedicated device for each model of the mobile terminal 3. Accordingly, among the connection terminals included in the charging device 2, the shape and specifications (for example, power value) of the connection terminal connected to the mobile terminal 3 side are different for each model of the mobile terminal 3. However, in the present embodiment, among the connection terminals included in the charging device 2, the shape and specifications of the connection terminals connected to the data backup device 1 are the same regardless of the model of the mobile terminal 3.

  In general, the data backup device 1 is higher in cost (for example, manufacturing cost) than the charging device 2. In the present embodiment, since the shape and specifications of the connection terminal between the data backup device 1 and the charging device 2 are shared, the charging device 2 must be replaced with the replacement of the portable terminal 3. Even so, the same data backup device 1 can be used.

  Furthermore, if the data backup device 1 shown in FIG. 1 is used, the shape and specifications of the connection terminals between the data backup device 1 and the charging device 2 are shared, so that the portable terminal 3 is replaced after data backup Even so, the backed up data can be easily restored to the portable terminal 3 after the exchange.

  In addition, when it is not necessary to back up the data stored in the mobile terminal 3, the mobile terminal 3 can be charged only by connecting the mobile terminal 3 and the charging device 2. By doing so, when it is not necessary to back up data (for example, when going out for only a few days), only the mobile terminal 3 and the charging device 2 need to be carried.

  When performing data backup, the control unit 12 detects that the data backup device 1 is connected to the portable terminal 3 via the charging device 2 using the data connection unit 16. Further, when the control unit 12 detects that the data backup device 1 is connected to the portable terminal 3, the control unit 12 reads data stored in the portable terminal 3 through the charging device 2 using the data connection unit 16. In addition, the control unit 12 writes data read from the portable terminal 3 to the data storage unit 13.

  The control unit 12 reads data from the data storage unit 13 when restoring data. Further, the control means 12 uses the data connection means 16 to write the data read from the data storage means 13 to the portable terminal 3 via the charging device 2.

  Specifically, the data storage means 13 is a data reading device to which an external storage medium 13A can be attached. For example, the data storage means 13 is a card reader / writer capable of mounting an SD memory card as the external storage medium 13A.

In the present embodiment, the data backup device 1 includes, as the setting unit 17, for example, an operation unit having a user interface in the shape of a changeover switch as shown in FIGS. The user can set the two operation modes of the backup mode and the restore mode by operating the switch of the setting means 17. Also, as shown in FIG. 4, three modes may be set by adding an invalid mode, which is an operation mode in which neither backup nor restoration processing is executed, to the backup mode and the restore mode.

  FIG. 4 shows a case where the setting means 17 has a structure in which the knob portion 42 for switching the three states is incorporated in the switch 41, but the specific structure of the setting means 17 is the same as that of the present embodiment.

Then, the notification means 18 notifies the user of a plurality of states of the data backup device 1 based on the difference in the color to be emitted and the blinking pattern.

  The notification unit 18 is not limited to the light emitting diode, and may be realized by, for example, a liquid crystal display device. Further, the notification means 18 does not have a user interface that can be visually recognized from the outside, and may be realized by, for example, a sound output device such as a speaker. In this case, the notification unit 18 may notify the user of the state of the data backup device 1 using only voice. Further, the notification means 18 may notify the state of the data backup device 1 by using a sound output device and a light emitting diode or a liquid crystal display device in combination.

It may be used as an adapter. In this case, the data backup device 1 may be provided with a power outlet instead of the charging device 2, and the data backup device 1 may directly obtain power using the power outlet provided by itself. However, if the data backup device 1 is provided with a power outlet, the data backup device 1 must be carried even when it is not necessary to back up the data (for example, when going out for only a few days).

  Further, FIG. 1 shows the case where the data storage unit 13 is a data reader capable of mounting the external storage medium 13A, but the data storage unit 13 is not limited to that shown in the present embodiment. For example, the data storage unit 13 may be a storage device such as a hard disk device or a flash memory built in the data backup device 1. In addition, the data backup device 1 may use a combination of a storage device such as a hard disk device or a flash memory and a data reading device to which the external storage medium 13A can be attached as the data storage unit 13.

  3 shows the case where the mobile terminal 3 includes the power supply unit 31 and the charging unit 32, the charging device 2 may include the power supply unit and the charging unit, respectively.

  Next, an operation in which the data backup device 1 performs backup and restoration processing will be described. FIG. 5 is a flowchart illustrating an example of backup and restoration processing performed by the data backup device 1.

  First, when the user charges the mobile terminal 3 and wants to back up or restore the data stored in the mobile terminal 3, the user connects the data backup device 1 to the charging device 2 and attaches the mobile terminal 3 to the charging device 2. To do. The control means 12 of the data backup device 1 detects that it is connected to the portable terminal 3 via the charging device 2 through the data connection means 16. In this case, for example, the control unit 12 detects that the portable terminal 3 is connected via the charging device 2 by detecting the continuity of the data connection unit 16 that is a connection connector.

  When the connection of the portable terminal 3 is detected, the control unit 12 first determines whether or not the operation mode is set to the backup mode by the setting unit 17 (step S101). If it is determined that the backup mode is set, the control unit 12 executes a data copy process for copying the data from the portable terminal 3 to the data storage unit 13 (step S102). That is, the control unit 12 backs up data from the portable terminal 3 to the data storage unit 13.

  In step S <b> 102, for example, the control unit 12 transmits a transmission request for data to be backed up to the portable terminal 3 via the charging device 2. Then, the portable terminal 3 starts reading data from the storage unit 34 and transmits the data to the data backup device 1 via the charging device 2. The control unit 12 receives data to be backed up from the portable terminal 3 via the charging device 2. The control unit 12 instructs the data storage unit 13 to back up the received data. Then, the data storage unit 13 stores the received data in the external storage medium 13A according to the instruction of the control unit 12.

  When the data copy process is completed, the control unit 12 generates a backup ID for identifying the backup process performed in step S102 (step S103). And the control means 12 performs the write-in process to the portable terminal 3 of produced | generated backup ID (step S104). In this case, the control unit 12 transmits the generated backup ID to the mobile terminal 3 via the charging device 2. Then, the mobile terminal 3 writes the backup ID received from the data backup device 1 via the charging device 2 in the storage unit 34. That is, the control unit 12 stores the generated backup ID in the mobile terminal 3 via the charging device 2.

  When the writing process of the backup ID to the portable terminal 3 is completed, the control unit 12 ends the data backup process in the backup mode.

  When it is determined in step S101 that the operation mode set by the setting unit 17 is not the backup mode, the control unit 12 determines whether or not the set operation mode is the restore mode (step S105). When it is determined that the restore mode is not set (for example, when the operation mode is not properly set or invalid mode is set), the control unit 12 ends all the processes as they are. That is, when the control unit 12 determines that the invalid mode is set by the setting unit 17, data backup from the portable terminal 3 to the data storage unit 13 and data restoration from the data storage unit 13 to the portable terminal 3 are performed. Control is performed so that neither of the above is executed. In this case, the control unit 12 may notify the user using the notification unit 18 that the operation mode has not been properly set.

  When it is determined that the operation mode is the restore mode, the control unit 12 executes a process of reading from the portable terminal 3 a terminal ID for identifying the portable terminal 3 and a backup ID stored in the portable terminal 3 ( Step S106). In this case, the control unit 12 transmits a transmission request for the terminal ID and the backup ID to the portable terminal 3 via the charging device 2. Then, the mobile terminal 3 extracts the terminal ID and the backup ID from the storage unit 34 and transmits them to the data backup device 1 via the charging device 2. And the control means 12 receives terminal ID and backup ID from the portable terminal 3 via the charging device 2. FIG.

  Whether the backup ID from the portable terminal 3 is correct by using the terminal ID from the portable terminal 3 and the device ID for identifying the data backup device 1 stored in the data backup device 1 itself. Is determined (step S107). If it is determined that the backup ID is not correct, the control unit 12 ends the process without performing the data restoration process. Even when the backup ID cannot be read from the portable terminal 3, the control unit 12 ends the restore mode process without performing the data restoration process. In this case, the control unit 12 may notify the user using the notification unit 18 that the backup ID is incorrect or that the backup ID cannot be read from the portable terminal 3.

  In the present embodiment, in step S107, the control unit 12 determines whether or not the mobile terminal 3 stores a backup ID. When it is determined that the portable terminal 3 stores the backup ID, the control unit 12 determines that the backup ID stored in the portable terminal 3 is a terminal ID corresponding to the portable terminal 3 and a device ID corresponding to the data backup device 1. It is determined whether or not the ID is generated based on the ID. When the control unit 12 determines that the backup ID stored in the mobile terminal 3 is an ID generated based on the terminal ID corresponding to the mobile terminal 3 and the device ID corresponding to the data backup device 1, the backup ID is stored. It is determined that the ID is correct.

  When it is determined in step S107 that the backup ID is correct, the control unit 12 executes a data copy process (data restoration process) of data backed up by the data storage unit 13 to the portable terminal 3 (step S108). That is, the control unit 12 determines that the operation mode is set to the restore mode by the setting unit 17, and restores data from the data storage unit 13 to the portable terminal 3. In this case, the control unit 12 causes the data storage unit 13 to read data stored as backup data in the external storage medium 13A. Then, the control unit 12 transmits the data read by the data storage unit 13 to the mobile terminal 3 via the charging device 2. Then, the mobile terminal 3 receives data from the data backup device 1 via the charging device 2 and writes the received data in the storage unit 34.

  When the data copy process is completed, the control unit 12 ends the process in the restore mode.

  Next, a method in which the control unit 12 generates a backup ID in step S103 will be described. FIG. 6 is an explanatory diagram showing an example of a method by which the control unit 12 generates a backup ID. For example, as shown in FIG. 6, the backup ID can be generated using a terminal ID 301 of the portable terminal and a device ID 302 of the data backup device. For example, the control unit 12 creates a single character string by combining the terminal ID and the device ID, and generates a hash value 303 of the created character string. In this case, the control unit 12 generates a 40-byte backup ID 304 using, for example, SHA-1, which is the most common hash value generation algorithm.

  For example, when the mobile terminal 3 is a mobile phone, the backup ID generated by the method described above is recorded in the memo field of the address information of the owner of the mobile phone, so that data can be obtained even when the model is changed. Can be restored. Also, by recording the generated backup ID in the name field of a plurality of vacant address information, data can be restored even when the model is changed.

  Note that when the user operates the setting unit 17 to designate the backup mode or the restore mode, the user may accidentally set the reverse mode. Therefore, in step S102 and step S108 shown in FIG. 5, the control unit 12 refers to the data stored in the mobile terminal 3 and the data stored in the data storage unit 13 to detect an operation that may be erroneous. You may do it. The control means 12 may warn the user using the notification means 18 when an operation error is detected.

  For example, when the control unit 12 reads out data stored in the mobile terminal 3 via the charging device 2, the data storage unit 13 associates the name of the read data with a time stamp indicating the time when the data is read out. Remember me. Thereafter, when the data stored in the portable terminal 3 is backed up in the data storage unit 13, the control unit 12 in step S102, before starting data copying from the portable terminal 3 to the data storage unit 13, Check the time stamp of the data stored by.

  For example, the control unit 12 specifies data having the same name as the data to be backed up among the data stored in the past by the data storage unit 13. Then, the control unit 12 determines that the time indicated in the type stamp corresponding to the specified data is the same as the time indicated in the time stamp corresponding to the data to be backed up, or the time stamp corresponding to the specified data. If it is determined that the indicated time is newer than the time indicated in the time stamp corresponding to the data to be backed up, the notification means 18 is notified of a warning to the user of the portable terminal 3. In this case, the control unit 12 determines whether or not the time stamp of the data stored in the external storage medium 13A by the data storage unit 13 is new (or the same) as compared with the data type stamp stored in the portable terminal 3. Or not). When it is determined that the time stamp is new (or the same), the control unit 12 determines that there is a high possibility that the backup is not necessary, and the notification unit 18 uses the voice, light of a specific color, text, etc. May be used to warn the user.

  Since the data stored in the mobile terminal 3 is generally composed of a plurality of files, the control means 12 compares the time stamps between files having the same file name. Further, the control unit 12 may warn the user every time it finds a file that does not need to be backed up if a file that has a high possibility of not needing backup is found. Further, the control unit 12 may compare the time stamps of all the files, and if only one file is found that is highly likely not to be backed up, the control unit 12 may collectively alert the user once.

  Further, for example, in step S108, the control unit 12 confirms the total amount of data stored in the external storage medium 13A by the data storage unit 13 before starting data copying from the data storage unit 13 to the portable terminal 3. May be.

  For example, when the control unit 12 restores the data stored in the data storage unit 13 to the mobile terminal 3, the data having the same name as the data stored in the data storage unit 13 among the data stored in the mobile terminal 3. Is identified. In addition, the control unit 12 is configured such that the total data amount of the specified data is the same as the total data amount of the data stored in the data storage unit 13 or the total data amount of the specified data is stored in the data storage unit 13. If it is determined that the total data amount is larger than the total data amount, the notification means 18 is notified of a warning to the user of the portable terminal 3. In this case, the control unit 12 determines whether or not the total data amount stored in the mobile terminal 3 is larger (or the same) than the total data amount stored in the external storage medium 13A. When it is determined that the total data amount is large (or the same), the control unit 12 determines that there is a high possibility that the data restoration is not necessary, and the notification unit 18 causes the voice or light of a specific color, The user may be warned using characters or the like.

  Further, as described above, when a warning is issued to the user, a means for the user to respond to the warning may be provided. For example, when the user performs an operation of turning the switch of the setting unit 17 illustrated in FIGS. 1 and 4 to the opposite side, the control unit 12 may determine that the user has accepted the warning. Conversely, when a predetermined time or longer (for example, 10 seconds) has elapsed without any operation by the user, the control unit 12 may interrupt the data copy process and end the backup process or the restoration process. Further, when it is desired to continue the backup process and the restoration process without responding to the warning, for example, an operation for temporarily turning on the switch of the setting unit 17 shown in FIGS. 1 and 4 and then putting it back on again. The user may perform it within a total of 2 seconds. Then, according to such a user's instruction to continue the process, the control unit 12 may determine to continue the process, and may continue the backup process or the data restoration process.

  As described above, according to the present embodiment, the data backup device 1 and the mobile terminal 3 are connected via the charging device 2 in order to back up the data stored in the mobile terminal 3 using the data backup device 1. To be configured. Therefore, regardless of the model of the portable terminal 3, the shape and specification of the connection portion between the data backup device 1 and the charging device 2 can be shared. Therefore, the data stored in the mobile terminal 3 can be backed up regardless of the model of the mobile terminal 3. Further, when the terminal is changed due to a failure or loss of the portable terminal 3, replacement by purchase, etc., the backup data can be restored using simple means only for the only portable terminal after the change of the terminal. In addition, data stored in the mobile terminal 3 can be easily backed up on a daily basis, and data can be easily restored using simple means when necessary.

  Further, according to the present embodiment, data can be backed up while the mobile terminal 3 is being charged simply by placing the mobile terminal 3 on the charging device 2 (for example, a charging cradle). This eliminates the need for the user to perform special work for backup. Also, by using a sufficiently long charging time, the user can be made unaware of the waiting time for backup. Further, differences in the shape and voltage value of the charging terminal and the data transfer terminal that may be different for each portable terminal 3 can be absorbed via the charging device 2 (charging cradle). Therefore, the design of the charging device 2 (charging cradle) and the data backup device 1 (backup cradle) is changed from the design of the mobile terminal 3 (for example, the terminal shape) Design) can be done independently.

  Further, according to the present embodiment, the data backup device 1 restores data only to the backup source mobile terminal 3 even if the backup data is to be restored to a mobile terminal different from the backup source mobile terminal 3. Control to do. Further, the data backup device 1 performs control so that data cannot be restored to a terminal other than the terminal that has transferred both the terminal ID and the dedicated backup ID from the backup source portable terminal 3. If the backup ID is generated as a hash value based on the terminal ID of the portable terminal 3 and the device ID of the data backup device, it is difficult to falsify the backup ID. In addition, although it is a simple mechanism, it is possible to prevent unauthorized copying of backup data.

  Moreover, according to this Embodiment, the data backup device 1 can identify the portable terminal 3 by using backup ID. Further, it is possible to eliminate the need for the data backup device 1 itself to store the terminal ID of the mobile terminal 3. Therefore, if the data backup device 1 includes a memory card reader / writer to back up data to the memory card, even if the data backup device 1 itself has low tamper resistance, the terminal ID of the portable terminal 3 or The backup ID can be prevented from being read. Further, it is possible to eliminate the necessity of providing a special function for backup and restoration on the portable terminal 3 side.

  Furthermore, according to the present embodiment, by providing the data backup device 1 with a memory card reader / writer, the portable terminal 3 can be made lighter than when the card portable terminal is provided with a memory card reader / writer. Can be configured. Moreover, the risk of losing the portable terminal 3 together with the backup data while the memory card is inserted into the portable terminal 3 can be eliminated.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to the drawings. In the first embodiment, the case where the setting of the operation mode for performing the backup process or the data restoration process is performed using the setting unit 17 has been described. However, in the present embodiment, the data backup device 1 Automatically determines the operation mode.

  In the present embodiment, the hardware configuration when performing data backup or data restoration using the data backup device 1 is the same as the hardware configuration shown in FIG. Moreover, in this Embodiment, the structure of the data backup apparatus 1, the charging device 2, and the portable terminal 3 is the same as those structures shown in FIG.

  FIG. 7 is a flowchart illustrating an example of processing in which the data backup device 1 automatically determines the operation mode. In the present embodiment, the control means 12 of the data backup device 1 executes the processing from step S401 to step S404 instead of the processing of step S101 shown in FIG. Further, in the present embodiment, the control means 12 executes the processes from step S405 to step S407 instead of the process of step S105 shown in FIG.

  First, the control means 12 determines whether or not the data storage means 13 has already stored backup data in the external storage medium 13A (step S401). That is, the control unit 12 determines whether backup data is written in the data storage unit 13. If it is determined that the external storage medium 13A does not store backup data, the control means 12 sets the operation mode to the backup mode as it is (step S404).

  If it is determined that the backup data is stored, the control unit 12 next stores the backup data stored in the external storage medium 13 </ b> A from the portable terminal 3 currently connected to the data backup device 1. It is determined whether or not there is (step S402). That is, the control unit 12 determines whether the backup data written in the data storage unit 13 is data that has been backed up in the past from the portable terminal 3 that has detected the connection using the data connection unit 16.

  For example, the data backup device 1 stores in advance the terminal ID of the portable terminal together with the backup data in the data storage unit 13 at the time of data backup. When the portable terminal 3 is connected to the data backup device 1 again, the control means 12 checks the terminal ID stored at the time of backup with the terminal ID of the currently connected portable terminal 3. And the control means 12 can identify the portable terminal 3 by determining whether terminal ID matched based on the collation result.

  When it is determined that the backup data is data of the currently connected mobile terminal 3, the control means 12 determines whether or not the currently connected mobile terminal 3 stores more than a predetermined number of privacy information. Judgment is made (step S403). The privacy information is data such as a memory dial, received mail, transmitted mail, schedule, and the like. Specifically, in step S <b> 403, the control unit 12 transmits a transmission request for the number of data of the memory dial stored in the mobile terminal 3 to the mobile terminal 3 through the charging device 2. Then, according to the request from the data backup device 1, the mobile terminal 3 calculates the data number of the memory dial stored in the storage unit 34 and transmits it to the data backup device 1 via the charging device 2. When the control unit 12 determines that data such as 10 or more memory dials is stored, the control unit 12 determines that the mobile terminal 3 stores a sufficient amount of privacy information.

  If it is determined that the mobile terminal 3 stores a sufficiently large number (more than a predetermined number) of privacy information, the control unit 12 sets the operation mode to the backup mode (step S404). When the operation mode is set to the backup mode, the control unit 12 proceeds to the process of step S102 shown in FIG. 5 and starts the data backup process.

  When it is determined in step S402 that the backup data is not data of the currently connected mobile terminal 3, the control unit 12 determines whether the mobile terminal 3 stores data to be backed up. If it is determined in step S403 that the mobile terminal 3 does not store a predetermined number or more of privacy information, the control unit 12 determines whether the mobile terminal 3 stores data to be backed up ( Step S405). For example, the control unit 12 determines whether or not the mobile terminal 3 stores memory dial data, received mail, sent mail, images taken with a camera attached to the mobile terminal 3, and the like.

  If it is determined that the portable terminal 3 stores data to be backed up, the control unit 12 sets the operation mode to the invalid mode (step S406) and ends the process as it is. That is, when the control unit 12 determines that the operation mode is not set to either the backup mode or the restore mode, the control unit 12 sets the operation mode to the invalid mode.

  If it is determined that the portable terminal 3 does not store data to be backed up, the control unit 12 sets the operation mode to the restore mode (step S407). When the operation mode is set to the restore mode, the control unit 12 proceeds to the process of step S106 shown in FIG. 5 and starts the data restoration process.

  As shown in the first embodiment, if the method for storing the backup ID in the mobile terminal 3 is used, it is possible to prevent the backup data from being restored to another mobile terminal having a different terminal ID. Further, even when the model of the portable terminal 3 is exchanged, the backup data can be restored to the portable terminal 3 after the exchange. However, when the mobile terminal 3 before replacement breaks down or the mobile terminal 3 is lost, the backup ID cannot be transferred to the mobile terminal 3 after replacement, and the backup data cannot be restored.

  On the other hand, in the present embodiment, the terminal ID of the portable terminal 3 is stored in the data storage means 13 of the data backup device 1 when performing backup, so that the portable terminal 3 before replacement is damaged or lost. Even in such a case, data can be restored to the terminal after replacement.

Embodiment 3 FIG.
Next, a third embodiment of the present invention will be described with reference to the drawings. In the first embodiment and the second embodiment, the case where the control unit 12 of the data backup apparatus 1 performs generation and confirmation of the backup ID has been described. In the present embodiment, a case will be described in which the portable terminal 3 performs processing for generating and confirming a backup ID according to a program (software). FIG. 8 is a block diagram illustrating another configuration example of the data backup device 1, the charging device 2, and the mobile terminal 3. As shown in FIG. 8, in the present embodiment, the mobile terminal 3 further includes a program (software) storage unit and a program execution unit in addition to the components shown in FIG.

  As shown in FIG. 8, in the present embodiment, the mobile terminal 3 includes a data storage unit 34a and a program storage unit 34b instead of the storage unit 34, so that the first embodiment and the second embodiment are included. The form is different. In the present embodiment, the mobile terminal 3 is a CPU that executes a program (software) stored in the program storage unit 35b in addition to the components shown in the first embodiment and the second embodiment. (Central processing unit) 37 is included. The data storage unit 34a and the program storage unit 34b are specifically realized by a storage device such as a memory installed in the mobile terminal 3.

  In the present embodiment, at least one of the programs (software) stored in the program storage unit 34b functions as a data backup device using unit capable of executing processing related to the backup ID. Hereinafter, a program (software) that functions as a data backup device utilization unit is referred to as a backup application.

  The portable terminal 3 may store a backup application in the program storage unit 34b in advance. Further, the mobile terminal 3 may take in a backup application from the outside and store it in the program storage unit 34b. For example, a mobile phone sold by each mobile phone company (NTT DOCOMO, KDDI, Vodafone, etc.) has a function of downloading application software (hereinafter also simply referred to as an application) via a communication line. . In addition, the mobile phones sold by each mobile phone company have functions that can save downloaded applications or execute them whenever the user wants to use them. Using such a mechanism such as downloading, a backup application can be taken into a mobile phone and used for data backup and restoration.

  FIG. 9 is a flowchart illustrating an example of backup and restoration processing performed by the mobile terminal 3. In the present embodiment, the CPU 37 of the mobile terminal 3 executes processing according to the backup application stored in the program storage unit 34b. As shown in FIG. 9, when data backup is performed, the CPU 37 performs data backup processing according to substantially the same processing from step S101 to step S104 shown in FIG. 5 (steps S101a to S104a).

  In this embodiment, when generating the backup ID, the CPU 37 of the mobile terminal 3 instead of the control means 12 of the data backup device 1 generates the backup ID according to the backup application. In this case, the point that the CPU 37 generates a backup ID by referring to the device ID of the data backup device 1 and stores it in the data storage means 34a of the portable terminal 3 is the case where the control means 12 is used to generate the backup ID. Different. For example, in step S <b> 103 a, the CPU 37 transmits a device ID transmission request to the data backup device 1 via the charging device 2. Then, the data backup device 1 transmits the device ID to the portable terminal 3 via the charging device 2 according to the request. Then, the CPU 37 generates a backup ID based on the received device ID and the terminal ID of the mobile terminal 3 itself stored in advance in the data storage unit 34a.

  Further, when restoring data as shown in FIG. 9, the CPU 37 determines whether or not the restore mode is set in accordance with the processing substantially similar to step S105 shown in FIG. 5 (S105a). If it is determined that the restore mode is set, the CPU 37 executes a device ID read process from the data backup device 1 (step S106a). In this case, the CPU 37 transmits a device ID transmission request to the data backup device 1 via the charging device 2. Then, the data backup device 1 transmits the device ID to the portable terminal 3 via the charging device 2 according to the request.

  When restoring data from the data backup device 1 to the portable terminal 3, the CPU 37 determines whether or not the portable terminal 3 stores a backup ID. When determining that the backup ID is stored, the CPU 37 determines whether or not the stored backup ID is generated using the terminal ID of the mobile terminal 3 itself and the device ID of the data backup device 1. It is determined whether or not the backup ID is correct (step S107a). In this case, the CPU 37 determines whether or not the backup ID is correct using the device ID received from the data backup device 1 in step S106a.

  When determining that the backup ID is correct, the CPU 37 executes a process of restoring data from the data storage unit 13 of the data backup device 1 to the data storage unit 34a of the portable terminal 3 (step S108a). In this case, the CPU 37 transmits a restoration data transmission request to the data backup device 1 via the charging device 2. Then, the control means 12 of the data backup device 1 instructs the data storage means 13 to start reading the restored data from the external storage medium 13A. In addition, the control unit 12 transmits the restored data read from the external storage medium 13 </ b> A by the data storage unit 13 to the portable terminal 3 through the charging device 2. Then, the CPU 37 stores the received restoration data in the data storage unit 34a.

  Note that the data copy processing in step S108a may be performed by the control means 12 of the data backup device 1 or may be performed by the mobile terminal 3 according to the backup application, similarly to the processing in step S108 shown in FIG.

Embodiment 4 FIG.
Next, a fourth embodiment of the present invention will be described with reference to the drawings. In this embodiment, a portable terminal using a terminal ID is used in order to prevent backup data including music and application software distributed for a fee from being illegally restored to a portable terminal of another person other than the user. A case where a method other than the identification of 3 is used will be described.

  In the present embodiment, the hardware configuration when performing data backup or data restoration using the data backup device 1 is the same as the hardware configuration shown in FIG. Moreover, in this Embodiment, the structure of the data backup apparatus 1, the charging device 2, and the portable terminal 3 is the same as those structures shown in FIG.

  FIG. 10 is an explanatory diagram showing an example of data stored in the mobile terminal 3 (mobile phone in this example). As shown in FIG. 10, the cellular phone stores data 51 including privacy information such as a memory dial, received mail, transmitted mail, and personal schedule in the storage unit 34.

  Further, the mobile phone also stores data 52 including charged images such as standby images, incoming melody, music, and applications in the storage means 34. In this case, in particular, if paid content is copied to another person's mobile phone or the like without permission, it may be disadvantageous for the seller of the content and may also violate the copyright law for the user.

  On the other hand, the privacy information of the owner of the mobile phone is expected to include information that the user does not want to be seen by others. Therefore, it is considered that the owner (user) of the mobile phone and the data backup device 1 tries to prevent the data 51 including the privacy information from being copied to another person's mobile phone or the like.

  In the present embodiment, the collective backup data 53 in which the data 51 including the privacy information and the data 52 including the pay content are collectively generated when the data backup is performed using the psychological characteristics of the user as described above. To do. In this case, the data backup device 1 generates batch backup data 53 in which data 51 including at least privacy information and data 52 including paid content are combined into one piece of data stored in the mobile terminal 3. Then, the data backup device 1 backs up the generated batch backup data in an indivisible form (stores it in the data storage means 13). The data backup device 1 also restores the batch backup data 53 to the portable terminal 3 as it is via the charging device 2 even when restoring the backup data to the portable terminal 3. By doing so, it is possible to prevent the act of restoring the backup data to the portable terminal 3 of another person.

  A method for making the batch backup data 53 indivisible will be described. For example, the data backup device 1 controls individual data such as a memory dial included in the batch backup data 53 so as not to provide a means for dividing or extracting data in any mode of backup and restoration. The batch backup data 53 is made indivisible. Further, for example, the data backup device 1 makes the batch backup data 53 indivisible by archiving the batch backup data 53 as a single binary data in a unique format. Further, the data backup device 1 makes the batch backup data 53 inseparable by encrypting the batch backup data 53 using the unique ID of the data backup device 1 as a key at the time of backup and decrypting it at the time of restoration.

  Further, after the backup data is once restored to the portable terminal 3, the control means 12 of the data backup device 1 may store the restoration time in the data storage means 13. Then, the control unit 12 of the data backup device 1 may perform control so as to prohibit the next restoration until a predetermined time has elapsed from the restoration time. Such control can be easily realized by providing a timer (not shown) in the data backup device 1. By doing so, it is possible to prevent unauthorized mass duplication of paid content in such a way that data backed up from one mobile terminal 3 is restored to a plurality of other mobile terminals 3 collectively. Can do.

  In this embodiment, instead of using the backup ID, the data backup device 1 includes privacy information such as memory dial information input by the user of the mobile terminal 3 in the data stored in the mobile terminal 3. Backup may be permitted only when a predetermined amount of data is included. Further, the data backup device 1 may restore the privacy information and the pay content without dividing them. The data backup device 1 may permit the data restoration again only when a sufficient time has elapsed after the data restoration. By doing so, illegal copying of paid content using the data backup device 1 can be prevented.

Embodiment 5. FIG.
Next, a fifth embodiment of the present invention will be described with reference to the drawings. In the first to fourth embodiments, the case where one data backup device 1 backs up data of one mobile terminal 3 has been described. In this embodiment, a case where data of a plurality of portable terminals 3 is backed up using one data backup device 1 will be described.

  In the present embodiment, the hardware configuration when performing data backup or data restoration using the data backup device 1 is the same as the hardware configuration shown in FIG. Moreover, in this Embodiment, the structure of the data backup apparatus 1, the charging device 2, and the portable terminal 3 is the same as those structures shown in FIG.

  FIG. 11 is an explanatory diagram showing a concept when data stored in a plurality of portable terminals 3 is backed up using one data backup device 1. As shown in FIG. 11, in the present embodiment, the data storage means 13 of the data backup device 1 groups backup data, and simultaneously stores a plurality of groups of backup data in the external storage medium 13A. In this case, the data backup device 1 may define a group for each portable terminal 3 or may define a group for each backup process.

  In the present embodiment, as shown in FIG. 11, the data backup device 1 defines a group for each mobile terminal 3 and causes the data storage means 13 to store backup data in a group for each mobile terminal 3 terminal. For example, the data backup device 1 stores the data stored in the mobile terminal 3a as group 1 as backup data 1301 with a terminal ID. Similarly, the data backup device 1 stores the data of the mobile terminal 3b and the mobile terminal 3c as group 2 and group 3 as backup data with terminal IDs 1302 and 1303, respectively.

  As shown in FIG. 11, when the data storage means 13 stores backup data in units of a plurality of groups, in the data copy process (steps S102 and S108) in the flowchart shown in FIG. It is necessary to execute.

  In the present embodiment, the control unit 12 reads data from the portable terminal 3 via the charging device 2 and creates a group each time the read data is backed up. Moreover, the control means 12 assign | provides terminal ID corresponding to the portable terminal 3 which read data to the produced group. The control unit 12 stores the terminal ID together with the read data in the data storage unit 13 for each group.

  When restoring the backed up data to the portable terminal 3, the control means 12 is a terminal that matches the terminal ID corresponding to the restoration-destination portable terminal 3 among the groups corresponding to the data stored in the data storage means 13. A group to which an ID is assigned is specified. And the control means 12 restore | restores the data corresponding to the specified group to the portable terminal 3 among the data which the data storage means 13 memorize | stores.

  FIG. 12 is a flowchart showing an example of sub-steps executed in the data copy process (step 102 shown in FIG. 5) from the portable terminal 3 to the data storage unit 13. In step S102, the control means 12 of the data backup device 1 first refers to the terminal ID of the portable terminal 3 (sub step S201). In this case, for example, the control unit 12 transmits a terminal ID transmission request to the portable terminal 3 via the charging device 2 and receives the terminal ID from the portable terminal 3.

  When receiving the terminal ID, the control means 12 newly creates a group to which the received terminal ID is assigned (substep S202). In this case, for example, the control means 12 creates a new group by assigning the terminal ID to the beginning or end of the backup data. Further, for example, the control unit 12 may use a file name of a group in which a terminal ID is newly created.

  Further, the control unit 12 copies the backup target data from the portable terminal 3 to the group area of the external storage medium 13A of the data storage unit 13 (substep S203).

  When the data copy is completed, the control means 12 determines whether there is data of a group having the same terminal ID on the external storage medium 13A other than the data copied in sub-step S203 (sub-step S204). When the terminal IDs are grouped as file names, the control means 12 avoids the risk of deleting an existing file before the completion of data copy by performing the determination process of sub-step S204 before sub-step S202. it can.

  If it is determined in sub-step S204 that there is no other group having the same terminal ID, the control means 12 ends the process of step S102 as it is and proceeds to the process of step S103. If it is determined that there is another old group having the same terminal ID, the control means 12 deletes the older group and deletes the data stored in the old group area (substep S205). When the deletion of data is completed, the control unit 12 ends the process of step S102 and proceeds to the process of step S103.

  FIG. 13 is a flowchart showing an example of sub-steps executed in the data copy process from the data storage means 13 to the portable terminal 3 (step S108 shown in FIG. 5). In step S108, the control means 12 of the data backup device 1 first searches the external storage medium 13A of the data storage means 13 for a group having the same terminal ID as the terminal ID read from the portable terminal 3 (substep). S301). Then, the control means 12 determines whether there is a group having the same terminal ID (substep S302).

  If it is determined that there is a group having the same terminal ID, the control unit 12 instructs the data storage unit 13 to read the restored data from the group area having the same terminal ID. And the control means 12 performs the process which copies the decompression | restoration data (backup data) which the data storage means 13 read to the portable terminal 3 (substep S303). In this case, the control unit 12 transmits the data read by the data storage unit 13 to the portable terminal 3 via the charging device 2. Then, the portable terminal 3 stores the restoration data from the data backup device 1 in the storage unit 34. When the copying is completed, the control unit 12 ends the process of step S108 and ends the data restoration process.

  If it is determined in sub-step S302 that there is no group having the same terminal ID, the control means 12 outputs using the notification means 18 that there is no data that can be restored in the portable terminal 3 (sub-step S304). And the control means 12 complete | finishes the process of this step S108, and complete | finishes a data restoration process.

Embodiment 6 FIG.
Next, a sixth embodiment of the present invention will be described with reference to the drawings. FIG. 14 is a block diagram illustrating still another configuration example of the data backup device 1, the charging device 2, and the mobile terminal 3. In the present embodiment, a case will be described in which the data to be backed up stored in the mobile terminal 3 includes content that is restricted in the number of uses and the use time.

  When the data stored in the mobile terminal 3 is backed up, even if the content stored in the mobile terminal 3 includes content that is restricted in the number of usages or usage time, the data is repeatedly restored many times. There is a possibility. For this reason, there is a possibility that these restrictions on contents with restrictions on the number of times of use and use time can be substantially invalidated. Therefore, if there are restrictions on the number of times the content can be used or the time of use, backup of such restricted content is prohibited on the mobile terminal 3 side, and data associated with an accident or model change that is the original purpose of backup. It is desirable to be able to maintain this.

  In the present embodiment, as shown in FIG. 14, the data backup device 1 includes a communication unit 19 in addition to the components shown in FIG. The communication means 19 of the data backup device 1 is connected to the server 8 via the network 7 such as the Internet.

  Specifically, the communication unit 19 is a network interface unit installed in the data backup device 1. The communication means 19 is used by the data backup device 1 to transmit various information to the server 8 via the network 7.

  In the present embodiment, the control means 12 inquires of the server 8 whether or not data restoration is possible via the network 7 by using the communication means 19 at the time of data restoration. For example, the control means 12 inquires whether data restoration is possible by transmitting the terminal ID of the portable terminal 3 connected via the charging device 2 to the server 8 via the network 7.

  Specifically, the server 8 is an information processing apparatus such as a workstation or a personal computer. The server 8 has a function of managing, for each mobile terminal 3, the usage frequency and usage time of content with usage restrictions. For example, the server 8 includes a database that stores the usage count and usage time of the content in association with the terminal ID of the mobile terminal 3.

  Further, the server 8 has a function of determining whether or not data restoration to the portable terminal 3 is possible in response to a request from the data backup device 1. For example, the server 8 receives the terminal ID of the portable terminal 3 that is the data restoration destination from the data backup device 1 via the network 7. Then, the server 8 determines whether or not the usage count and usage time of the content of the mobile terminal 3 have already exceeded the limit count and time limit based on the received terminal ID and the usage count and usage time stored in the database. Judging. If it is determined that the number of times or the time limit has been exceeded, the server 8 determines that data restoration to the portable terminal 3 is impossible. Then, the server 8 transmits instruction information for prohibiting data restoration to the portable terminal 3 to the data backup device 1 via the network 7. Then, the control means 12 of the data backup device 1 performs control so as not to restore data to the portable terminal 3 in accordance with an instruction from the server 8.

  As described above, according to the present embodiment, the server 8 manages the number of usages and the usage time of content, and determines whether or not data restoration to the portable terminal 3 is possible in response to an inquiry from the data backup device 1. . Therefore, data backup and restoration can be performed safely even for content that has usage restrictions.

  The present invention can be applied to the use of a data backup device that backs up data stored in a mobile terminal such as a mobile phone. In particular, the present invention can be applied to a data backup cradle that is connected to a charging cradle separately from an inexpensive charging cradle that can be attached to a portable terminal.
