FIG. 1 is a schematic diagram of one embodiment of an apparatus of the present invention.

Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The embodiment of the terminal control method comprises the following steps:

step 1: the method comprises the steps that a first storage terminal acquires first information, wherein the first information originates from the outside of the first terminal and has security relevance with the first storage terminal.

The terminal may be a handheld mobile terminal such as a mobile phone, a tablet computer, and the like. In one embodiment of the present invention, the first storage terminal is a terminal that is inoperable, i.e., the user cannot control the terminal through normal operation. For example, for a mobile phone with a touch screen, a touch failure of the touch screen may cause a user to be unable to operate the mobile phone, and at this time, the mobile phone is an inoperable terminal; for touch screen failure, it can be caused by external force, such as impact causing screen rupture, or self failure.

As for the manner of acquiring the first information by the first storage terminal, it may be acquired by wireless communication, for example, acquired from the base station side through a mobile communication network, or acquired from another terminal or a hot spot through a short-range wireless communication network. For the case of obtaining from the base station side through the mobile communication network, it may be to obtain a short message transmitted through a signaling channel as the first information, or to obtain an instant message/mail or the like transmitted through a data channel as the first information. It is understood that even messages/mails or the like as described above may be acquired as the first information in a manner of passing through a short-range wireless communication network.

The following description will focus on short messages as an example, it being understood that the same applies to other types of information.

The first information is information originated from outside the first storage terminal, that is, the information originally stored in the first storage terminal does not belong to the first information. In addition, the first information is not arbitrary information, and is primarily related to the security of the first storage terminal, and if the first information is not related to the security of the first storage terminal, it does not belong to the first information described herein.

For the security association between the first information and the first storage terminal, the association manner is various and may be a preset information type. For example, when a short message is determined as the first message, the short message is associated with the security of the first storage terminal, and a message other than the short message, such as an instant message, is not associated with the security of the first storage terminal. For example, if the first information is sent to the first storage terminal through the information channel of the mobile communication network, the first information is information associated with the security of the first storage terminal according to a preset setting, and if the first information is received from the short-range wireless communication network at this time, only the information received through the mobile communication network is associated with the security according to the preset setting, so that the first information received from the short-range wireless communication network is considered not to be associated with the security.

This has the advantage that unnecessary interference can be eliminated, the information security of the first storage terminal is improved, and the processing efficiency can also be improved.

Step 2: judging whether the information carried outside the content of the first information meets a first preset condition or not;

The content of the first information as referred to herein may refer to a portion of the first information that carries user-level value in a particular way in a typical usage scenario. For example, in the case of a short message, the part of the short message viewed by the user is the content of the first message, and in the case of a short message sent from the base station to the terminal, the part of the signaling format added thereto is not considered to be the content of the first message. One specific example is: the first storage terminal receives the first information, the first information is a short message, the short message is that the user A sends the user B (the holder of the first storage terminal) that the user B means to inquire whether to eat dinner home or not, and then the user A edits the content of the short message, and the short message is 'do you go home to eat dinner or not in the evening'? ". After the first storage terminal receives the short message, the part in the quotation mark is considered as the content of the first message.

Similarly, the same is true for the receipt of WeChat messages, where the portion of the user-level value conveyed by the WeChat message is content. This is similar to a short message.

In addition to the content of the first information, the content of the first information may be determined based on the above explanation, and after it is determined what the content of the first information is, the content of the first information may be regarded as the content of the first information excluding the other parts after being related to the content of the first information.

In the embodiment of the present invention, the content of the first information may refer to a source of the first information, where the source may refer to a source of a user plane, and may also refer to a source of a communication plane. For the source at the user level, the user name (another user, for example, name of zhang san, lie si, etc.) or the phone number (for example, phone number) of the sender of the first information may be referred to; for the source of the communication plane, it may refer to a MAC address or an IP address or a gateway address, etc. of the sender of the first information.

In a further embodiment of the invention, the first information may be other than its content, for example, the amount of the first information. It is to be understood that the first message may comprise one or more specific messages, for example, the first message may comprise a plurality of short messages or a plurality of micro-message messages; this is the number of short messages or micro messages.

Of course, in the embodiment of the present invention, the above two schemes other than the content of the first information may be combined, that is, both the source and the quantity of the first information are included.

The first preset condition in this step may be, based on the user plane source of the first information, to determine whether the phone number of the sender of the first information is a phone number already stored in a storage record (e.g., an address book, a call record, etc.) of the first storage terminal; further, it may be determined whether the sender phone number is a phone number of a specific group in the storage record of the first storage terminal, such as a parent group.

For the situation that the storage record is a call record, the situation that the first storage terminal cannot be rescued because a certain telephone number is not stored in the address book can be solved, and in the situation, a user only needs to dial the telephone number of the first storage terminal first to enable the certain telephone number to exist in the call record. Thereby, the feasibility of rescue is improved and the efficiency is improved.

As for the communication layer source of the first information, it may be determined whether the MAC address of the sender device of the first information is in a preset MAC address list, or it may be determined whether the IP address of the sender device is in a preset IP address list.

In the embodiment of the present invention, in the description of the first preset condition corresponding to the source of the first information, a time element may be further added. That is, it is determined whether the source of the first message meets the limitation of the source part in the first predetermined condition within a predetermined time or within a predetermined time period or at a predetermined time point. This increases the reliability of the determination, and the security of the first storage terminal.

Based on the above, the content of the first information is not limited to the number, and the first preset condition may be to determine whether the number of the first information meets a preset number requirement, for example, the number of the first information reaches 3. Similarly, a time factor may be added, that is, whether the quantity of the first information meets the limitation of the quantity part in the first preset condition within a preset time or a preset time period or a preset time point or a regular time is judged. This also increases the reliability of the determination, and thus the security of the first storage terminal.

In a further embodiment of the invention, the determination of the first predetermined condition combines the source of the first information and the amount of the first information. That is, the source of the first information and the amount of the first information need to satisfy both the source and the amount specified in the first preset condition. This dual authentication helps to improve security. Meanwhile, if the time element is added, the triple verification can better guarantee the requirement on safety.

The first operation in this step is, in the embodiment of the present invention, to open the first authority of the first storage terminal. And the first authority may be an authority to read data in the first storage terminal. For maintaining the validity of the first state associated with the judgment result of the first preset condition and the information carried by the first information except the content meeting the first information within the preset time, the first state associated with the judgment result is a meaningful state or setting for subsequently rescuing the first storage terminal, and may correspond to the specific content of the first operation, for example, if the first operation is opening the first right, the first state is a state where the first right exists and is valid; the preset time highlights the state or the setting timeliness which is meaningful for rescuing the first storage terminal, so that the safety and the convenience are improved.

For validity within a predetermined time, maintaining permanent validity may be included in embodiments of the present invention. Therefore, the user can read the data in the first storage terminal at any time. Meanwhile, the first storage terminal can be used as a USB flash disk on the premise that the user does not want to repair the inoperability of the first storage terminal, and therefore the use efficiency and the economy are improved.

In the embodiment of the present invention, this step may specifically include permanently opening the right to read the data of the first storage terminal. The permanent opening represents the validity within a preset time, and the right to read the data of the first storage terminal can be understood as an enabled state, i.e. the first state.

In an embodiment of the present invention, for the case that the first storage terminal is a mobile phone, when the step is executed, when the USB connection mode originally set in the mobile phone is a non-MTP mode (for example, the USB charging mode), the connection mode is set to the MTP mode and is kept permanently valid, so as to ensure that the user can read the content in the mobile phone through the USB connection at any time.

When the connection mode set in the original mobile phone is originally the MTP mode, the MTP mode is maintained and set to be permanently effective when the first preset condition is judged to be satisfied.

Of course, in another embodiment of the present invention, the preset time is not limited to be permanently valid for validity within the preset time, and may be any time preset. More specifically, the setting of the preset time is embodied in the content of the first information, that is, the preset time is recorded in the content of the first information, and the first storage terminal enables the setting of the preset time after parsing the preset time in the first information.

It should be noted that, when the first storage terminal is in the locked state, if it is determined that the first preset condition is met, the first storage terminal is unlocked first and the unlocked state within the preset time is maintained. At this time, the unlock state may be considered as the first state, which is associated with the determination result. And then, setting the USB connection mode of the first storage terminal as the MTP mode. At this time, both the unlocked state and the state of the MTP mode may be considered as the first state.

Through the steps, the user can read the data in the first storage terminal according to the requirement of the user, and the risk caused by data loss is avoided.

In another embodiment of a terminal control method according to the present invention, on the basis of the above embodiment, the present embodiment adds a judgment on a second preset condition. Specifically, it is determined whether the content of the first information satisfies a second preset condition.

In this embodiment, it is determined whether the content of the first information satisfies a second preset condition, and if so; when the information carried outside the content of the first information also meets the first preset condition, that is, when the first preset condition and the second preset condition are both met, and the judgment result is positive, the first operation is executed and the validity of the first state associated with the judgment result meeting the first information and the first preset condition and the judgment result meeting the first information and the second preset condition within the preset time is maintained.

That is, the first state is associated with two determination results, and the association is shown here that the determination results are both positive, that is, two preset conditions are simultaneously satisfied.

For the content of the first information, in one embodiment of the invention, it may refer to a portion of one information having a user-level value. Continuing with the example of the above embodiment, a short message "do you go home and eat dinner at tonight? The part within the quotation mark is the part with user-level value, i.e. the content itself that is meaningful for the average end user.

For the second preset condition, in the embodiment of the present invention, it may be at least one of the following:

the method comprises the following steps that firstly, the content of first information accords with a preset format;

secondly, a first field of the content of the first information is consistent with first data in the first storage terminal;

and thirdly, the content of the first information accords with the preset format, and the first field of the content of the first information is consistent with the first data in the first storage terminal.

For condition one: the content of the first information conforms to a preset format, where the preset format may be a syntax rule of the content itself, or an arrangement rule of the content itself, or a semantic rule of the content itself, or a character of the content itself, and so on.

For example, the content of the first information may be content — "# 9527 #", in the quotation mark. The second predetermined condition may then be a rule that starts with # #andends with # with four digits in between.

As another example, the content of the first information may be the content in the quotation mark- "abcdef". The second preset condition may be a character string of at least 5 characters or more arranged in the order of the english alphabet.

As another example, the content of the first information may be content in a quotation mark, which is "rescue mobile phone acquisition right". The second preset condition may be that the content includes the meaning expression of the rescue and acquisition right.

As yet another example, the content of the first information may be the content in the quotation mark- "skjfasfa Ω". And the second preset condition may be that the content includes the omega character.

For condition two: the first field of the content of the first information is identical to the first data in the first storage terminal. Here, the first data in the first storage terminal may refer to a password of an open right of the first storage terminal, and the right may be a right to read data in the first storage terminal as described above, for example, unlocking a mobile phone and setting the mobile phone to an MTP connection mode.

The first field may be a specific field in the content of the first message when the first message is edited by the pre-rule. Examples are as follows:

the content of the first information may be the content in the quotation marks ". x 9527XXXX 7259", in which case the second predetermined condition may be starting with a first set of four digits, followed by ending with a first set of four digits and immediately preceding the ending with a second set of four digits, the first set of four digits and the second set of four digits including a set of characters therebetween, the first set of four digits and the second set of four digits being in a mirror image relationship with the set of characters as the center. And the set of characters is the first field conveyed in the content of the first information.

For condition three: the combination of condition one and condition two is used, and on the basis of the description of condition one and condition two, the skilled person can know how to combine condition one and condition two, and therefore the details are not repeated herein.

It should be noted that, the first field mentioned in the second condition is consistent with the first data, and the fact is that the validity is verified, after the verification is passed, if the original first storage terminal is in the locked state, the unlocking is performed at this time, and if the connection mode of the original first storage terminal is a mode other than the MTP mode, such as a charging mode, the MTP mode is set at this time.

The unlocked state and the state of the MTP connection mode can be referred to as the first state, and the time effectiveness of the first state can be referred to as the above description.

The existence of the second preset condition further verifies the acquisition of the authority on the content level, and the safety of data reading is improved.

It should be noted that, for information carried in addition to the content of the first information, the MAC address, the IP address, the telephone number, and the like described in the above embodiments may be put into the content of the first information to be determined, and only the positions where the information is extracted are different.

In addition, for the embodiment represented by the second preset condition, it may not be related to the embodiment represented by the first preset condition. That is, the first operation is performed only by judging the content of the first information, the first state is maintained to be valid, and the like. Since the person skilled in the art will know how to operate on the basis of the above description, no further description will be given.

A usage scenario is described in detail below by taking the first storage terminal as a mobile phone as an example:

due to the fact that the mobile phone Ta of the user A is carelessly used, the mobile phone Ta falls to the ground, the screen of the mobile phone Ta is broken, the display screen cannot display the mobile phone Ta, and the touch screen is also out of order. However, the important information of the user a is stored in the mobile phone Ta, and the user a tries to derive the important information in the mobile phone Ta.

Then, the user a connects the mobile phone Ta to the computer through the USB connection line. However, since the mobile phone Ta is unlocked, the computer cannot read the data in the mobile phone Ta after being connected to the computer. Also, the user a recognizes that even if the mobile phone Ta is unlocked, since it has previously set the USB connection mode of the mobile phone Ta to the charging mode, data cannot be read.

At this time, the user A finds that the mobile phone numbers of 4 colleagues A, B, C and D, and 4 colleagues A, B, C, D and E are stored in the address list. The user a makes the 4 colleagues edit a short message, and the content is ". about. 9527556677887259". After receiving the short message, the mobile phone Ta of the user a first judges whether the sources of the 4 short messages, namely the mobile phone number of the epdm is in the address list of the local phone, and counts 4 at this time after judging.

Then, the mobile phone Ta determines whether the contents of the four short messages meet a second preset condition, that is, according to the rule: beginning with a first set of four digits followed by a first set of four digits, ending with a second set of four digits followed by an ending with a second set of four digits, the first and second sets of four digits comprising a set of characters therebetween, the first set of four digits and the second set of four digits being in mirror image relation centered on the set of characters. And the characters between the first group of four digits and the second group of four digits are the unlocking password.

After judgment, the four short messages all meet the rule, and the extracted decoding password is consistent with the unlocking password stored in the mobile phone Ta.

Then, the mobile phone Ta considers that both the first preset condition and the second preset condition are satisfied, so that the mobile phone Ta is automatically unlocked, and the USB connection mode of the mobile phone Ta is set to the MTP mode. And the time-effectiveness is set to be permanent.

At this time, the user a can smoothly read the data in the mobile phone Ta after connecting the mobile phone Ta to the computer.

In another embodiment of the invention, based on the above description, to avoid others (e.g. epdm) reading data in the handset Ta jointly. After or before the user A reads the data of the mobile phone Ta, a user interface is output to the computer of the user A to receive a new password input by the user A, and the mobile phone Ta can replace the original password after receiving the new password. In this way, the aforementioned risk of data theft is avoided.

It is noted that for the data transfer of the first storage terminal, it may be based on the USB connection as described above, or may be based on a wireless connection. In general, any manner of connection and transmission is contemplated.

The present application also includes several embodiments that may be used in combination with the above embodiments, and further description of the combination is not provided herein since it will be apparent to those skilled in the art based on the description of how the combination may be made:

step 1, establishing communication connection between a first storage terminal and a second storage terminal;

the first storage terminal may be any electronic device with storage and control functions, such as a mobile phone, a tablet computer, a wearable device, and the like. The second storage terminal may be any electronic device with a storage function, such as a usb disk, a mobile hard disk, a mobile phone, a tablet computer, a hard disk, and so on.

In this step, the first storage terminal and the second storage terminal are first physically connected, for example, through a USB transmission medium, although other suitable methods may be adopted, and the present invention is not limited to specific connection and transmission method/protocol. Thereafter, a data communication connection, such as the USB communication connection described hereinabove, between the first storage terminal and the second storage terminal is created according to existing device discovery and connection establishment mechanisms.

In one embodiment of the invention, the first storage terminal is an inoperable device. By inoperable device, it may be meant an inoperable device due to some malfunction or accident. For example, for a terminal including a touch screen, it may be the case that the touch screen fails, or other faults of the touch screen cause the touch signal to be unrecognizable; the display screen failure may also be the case, which mainly means that the display screen failure causes the content to be unable to be displayed, specifically, for example, the screen is broken, and at this time, the user cannot see the operated object, so the operation is also the case of being unable.

And for the second storage terminal, it can be referred to as a rescue device. On which data needed for rescue are stored, i.e. needed for rescue of the first storage device. Therefore, the requirement on the device performance of the second storage device is not high, as long as the data required for rescue can be stored. In an embodiment of the present invention, the second storage terminal is an OTG device, so that the first storage terminal can be used as a host device to read data from the second storage terminal.

And 2, searching data meeting preset conditions in the second storage terminal by the first storage terminal, and taking the data meeting the conditions as first data.

Based on the fact that the communication between the first storage terminal and the second storage terminal in the previous step is not obstructed, the first storage terminal does the search in the second storage terminal in the current step.

The preset condition may be, in some embodiments of the present invention, a preset name (e.g., a file name), a preset date (e.g., a file created/modified on the current day), a preset format, a preset storage address, and the like. In short, as long as a certain data on the second storage terminal can be locked through the predetermined condition, what index is adopted for locking can be determined according to actual needs.

It should be noted that the data meeting the preset condition may be organized and stored in a file, and the file stores data required for rescue. Therefore, in this case, the search for data meeting the preset condition in this step may also be regarded as a search for a file meeting the preset condition, and the data is found when the file is found and is taken as the first data.

In another embodiment of the present invention, the data meeting the preset condition may also be organized and stored in a non-file manner, and only stored in the data itself. For example, in the case of presetting a storage address at the time of presetting a condition, it may be predetermined which sector/physical page/physical address, etc. of the storage space of the second storage terminal stores data required for rescue, which is a manner that the data is not organized in the form of a file but is in a data structure such as through various data volumes or data chains.

In any case, whatever the presentation, once the data is found, it is treated as the first data.

Step 3, the first storage terminal reads the first data in the second storage terminal;

in this step, after the connection establishment is completed in the previous step, the first storage terminal is used as a master device to read the first data in the second storage terminal.

The first data may be plaintext data, or may be data encrypted by a predetermined encryption method, where the plaintext or encryption is rejected from the requirement on the security level. If the data is encrypted, the first storage terminal may decrypt the first data after reading the first data, or may not decrypt the first data, depending on what the object is determined in the subsequent determination step, and if the determined object is plaintext data, decryption is required, and if the determined object is encrypted data, decryption may not be required.

And 4, judging whether the first data is consistent with preset data in the first storage terminal, if so, executing a first operation and keeping the validity of a first state associated with a judgment result that the first data is consistent with the preset data within preset time.

As is apparent from the above description, if it is agreed in advance that it is data in the clear, the preset data is also in the clear, which is directly compared with the first data; if the encrypted data is agreed in advance, the first data needs to be decrypted and then compared with the preset data, or the encrypted data can be directly compared in some encryption algorithms, and if the encrypted data is consistent, the data before encryption can be considered to be consistent, in this case, the encrypted first data is not decrypted, but directly compared with the preset data (obviously, the encrypted data).

In an embodiment of the present invention, the preset data in the first storage terminal is a password for obtaining the authority thereof, such as an unlocking password, a password for changing a connection mode between two terminals (MTP, PTP (camera picture transmission mode), charging mode), and the like.

For the description of this step, the following cases are also needed:

case 1: if the first storage terminal is connected with the second storage terminal in a USB mode, the first storage terminal is in a locking state, but the mode of the USB connection is an MTP mode; then, the preset data may be a password for releasing the locking state of the first storage terminal, that is, an unlocking password;

case 2: if the first storage terminal is connected with the second storage terminal in a USB mode, the first storage terminal is in a locking state, and the USB connection mode is a non-MTP mode; then, the preset data may also be a password for releasing the locking state of the first storage terminal, that is, an unlocking password; however, the unlocking password is used to change the USB connection mode. Based on this, the following steps may need to be added:

when the first storage terminal is in the MTP mode, the first storage terminal is unlocked and the connection mode of the first storage terminal is changed to the MTP mode.

Case 3: if the first storage terminal is connected with the second storage terminal in a USB mode, the first storage terminal is in an unlocked state, but the USB connection mode is a non-MTP mode; then, the preset data may be a password for changing the mode of the USB connection to the MTP mode. And when the first data is detected to be consistent with the password and the first storage terminal is in the unlocking state, modifying the connection mode into an MTP mode.

It should be noted that, in some cases, the password for unlocking and the password for changing the connection mode to MTP may be the same. That is, when the first data is consistent with the preset data, the unlocking is performed first, and if the first data is already in the unlocking state, the unlocking is skipped, and then the connection mode is changed to the MTP mode.

In this step, when the first data is consistent with the preset data, in order to ensure smooth progress of the rescue work, the settings related to the guarantee of the smooth progress of the rescue work are maintained to be valid. This step is stated to be valid for a preset time, which can be set as desired. In one embodiment of the invention, will remain permanently effective. For example, the unlocked state described above is permanently active, the setting of the MTP mode is permanently active, and so on.

The first operation in this step is an action of removing obstacles to ensure that the rescue work is smoothly performed.
