Description

Collaboration paring method and mobile device using the same}

The present invention relates to a collaborative pairing method and a mobile device applying the same, and more particularly, to a collaborative pairing method for selecting and registering mobile devices to perform collaboration and a mobile device applying the same.

In order to collaborate between mobile devices, several steps are required.

② Setting for Security

③ Selecting a collaborator to conduct collaboration

④ Exchange data for collaboration

⑤ Collaborate

⑥ End

As a method of selecting a collaborator to collaborate with a mobile device that can collaborate nearby, a method of colliding mobile devices to collaborate with each other and selecting a collaborator is used.

This is a method of detecting only a simple impact on the mobile device, which may pose a security risk. Consciously or unconsciously impacting other mobile devices that don't intend to collaborate nearby, collaboration with unintended mobile devices can be established, and unwanted personal information can be sent to unintended mobile devices. Because it can be.

In addition, someone may intentionally attempt to collaborate using his mobile device to intercept other people's personal information, which may cause problems such as personal information leakage and hacking.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a collaboration pairing method and a mobile device applying the same that can prevent the unintentional mobile device to participate in the collaboration.

In addition, another object of the present invention is to provide a collaborative pairing method that can help strengthen data security even after pairing and a mobile device applying the same.

According to an embodiment of the present invention, a pairing method for collaboration of a mobile device includes: detecting a first movement, which is a movement of the mobile device itself; Receiving information about a second movement, which is a movement of the other mobile device, from another mobile device; Determining whether the first movement coincides with the second movement; And registering the other mobile device as a collaborator when the first movement and the second movement coincide with each other.

The mobile device and the other mobile device may be moved by the user in the same manner, so that the first motion and the second motion occur respectively.

The pairing method may further include generating a first key using first motion data, wherein the information on the second motion is generated by the other mobile device using second motion data. The second key, and in the determining step, it is preferable to compare the first key and the second key to determine whether the first movement and the second movement match.

The first key generating step may include generating a first key using first motion data acquired during a predetermined time period, and a starting point of the predetermined time period may be a time point at which the first movement starts. have. Here, the time point at which the first movement is started may be a time point at which the first movement becomes a specific size or more.

The first key generating step may further include calculating averages of first motion data obtained for each of a plurality of divided sections constituting a predetermined time period; And generating the first key by listing the averages calculated in the calculating step.

When arranging the averages calculated in the calculating step, only bits of a specific portion of the averages may be listed.

The pairing method may further include encrypting, by the mobile device, data required for collaboration using the first key; Transmitting the encrypted data to the other mobile device; Receiving, by the mobile device, data encrypted with the second key from the other mobile device; Decrypting the encrypted data using the first key; And performing collaboration by using the decoded data.

Hereinafter, with reference to the drawings will be described the present invention in more detail.

1. For collaboration Pairing ( Pairing ) Action

Collaboration means two or more mobile devices working together, such as exchanging contacts, sending and receiving files, and sharing data.

In order to collaborate, two or more mobile devices are required to register each other as a collaborator. In this embodiment, the mobile devices that are not intended to collaborate are registered as collaborators only when the mobile devices move equally for a predetermined time. Prevent registration

For example, as illustrated in FIG. 1, when a user shakes two mobile devices with one hand while folding the mobile device with one hand, the same movement occurs in the two mobile devices. Accordingly, the two mobile devices detect the same movement, exchange their movement information with each other, confirm that they match, and register as a collaborator.

Since it is impossible for another third mobile device not held in the user's hand to follow the movement of the user's hand in the same way, the third mobile device is unlikely to be registered as a collaborator.

2. for collaboration Pairing  process

Hereinafter, a pairing process for collaboration of a mobile device will be described in detail with reference to FIG. 2. 2 is a flowchart provided to explain a pairing method for collaboration of a mobile device according to an embodiment of the present invention. In the present embodiment, a case in which pairing for cooperation is performed between two mobile devices 100-1 and 100-2 will be described.

As shown in FIG. 2, first, after inputting a collaboration start command through the mobile devices 100-1 and 100-2 (S210-Y), the user displays the mobile devices 100 as shown in FIG. 1. If the mobile device 100-1 or 100-2 is shaken while holding it with one hand (S220), the mobile devices 100-1 and 100-2 detect the movement (S230).

In FIG. 2, the motion detected by the mobile device-1 100-1 is denoted as motion-1, and the motion detected by the mobile device-2 100-2 is denoted as motion-2, thereby distinguishing the two. . However, since the mobile device-1 100-1 and the mobile device-2 100-2 are shaken together while being folded with one hand of the user as shown in FIG. 1, the motion-1 and the motion-2 are same.

In step S230, if the size of the motion is greater than a certain size (that is, a relatively large case) is detected, and if the motion is small, the motion is not detected. This is to prevent the mobile devices 100-1 and 100-2 from moving relatively small due to their daily activities.

On the other hand, the command to start the collaboration in step S210, can be input using a physical user interface (PUI) such as physical "collaboration start button" or a graphical user interface (GUI) such as a "collaboration application icon" displayed on the screen. Can be.

In operation S230, the mobile devices 100-1 and 100-2 that detect the movement start the timer in operation S240 and store movement data generated in the process of detecting the movement in operation S250.

On the other hand, when the timer is started in step S240, the mobile device may output a sound effect to inform the user that the timer has started.

In FIG. 2, the motion data generated by the mobile device-1 100-1 is represented by the motion data-1, and the motion data detected by the mobile device-2 100-2 is represented by the motion data-2. The two were distinguished. However, since the motion-1 of the mobile device-1 100-1 and the motion-2 of the mobile device-2 100-2 are the same, the motion data-1 and the motion data-2 are also the same. Meanwhile, in operation S250, the motion data are sorted and stored in chronological order.

Thereafter, when the timer expires (S260-Y), the mobile devices 100-1 and 100-2 generate a key using the stored motion data (S270).

In FIG. 2, the key generated by the mobile device-1 100-1 is denoted key-1, and the key detected by the mobile device-2 100-2 is denoted key-2, thereby distinguishing the two. . However, since the movement data-1 of the mobile device-1 100-1 and the movement data-2 of the mobile device-2100-2 are the same, the key-1 and the key-2 are the same.

In operation S260, when the timer expires, the mobile device may output an effect sound to inform the user that the timer has expired.

Thereafter, the mobile devices 100-1 and 100-2 exchange keys generated in step S270 (S280). When the mobile devices 100-1 and 100-2 confirm that the key generated by the counterpart received through the key exchange in step S280 is the same as the key generated by the mobile device (S290-Y), the counterpart mobile device Register as a collaborator (S300).

Since the key-1 of the mobile device-1 100-1 and the key-2 of the mobile device-2 100-2 are the same, the mobile devices 100-1 and 100-2 may register the other party as a collaborator. will be.

Thereafter, the mobile devices 100-1 and 100-2 collaborate using the key generated in step S270 (S310 to S340).

In detail, the mobile devices 100-1 and 100-2 encrypt data necessary for collaboration using their keys (S310), and transmit them to the counterpart (S320).

In addition, the mobile devices 100-1 and 100-2 decrypt the data received in operation S320 with their keys (S330), and perform collaboration using the decrypted data (S340).

If the collaboration performed between the mobile devices 100-1 and 100-2 is data sharing, the mobile devices 100-1 and 100-2 perform a procedure of storing the decrypted data in step S340. will be.

In the above embodiment, the mobile devices 100-1 and 100-2 determine whether to register a collaborator according to whether the keys generated in step S270 match each other, and the keys generated in step S270 are the mobile devices ( 100-1, 100-2) based on the movements. Therefore, whether or not the keys generated in step S270 are matched is determined according to whether the movements of the mobile devices 100-1 and 100-2 match.

Therefore, it can be said that whether to register a collaborator is ultimately determined according to whether or not the motion is matched.

3. Key Generation Method

Hereinafter, a method of generating keys by the mobile devices 100-1 and 100-2 will be described in detail with reference to FIGS. 3A and 3B. 3A and 3B conceptually illustrate a key generation process.

In FIG. 2, the motion data generated between the timer start time and the timer end time is stored, and the key is generated using the stored motion data.

3A illustrates a timer section formed by a timer start time and a timer end time. As shown in FIG. 3A, the timer section has a total of 8 sec, and is divided into 16 500 ms sections.

Only one 500 ms interval is shown in FIG. As shown in FIG. 3B, one 500 ms-section is further divided into five 100 ms-sections. As shown in FIG. 3B, it can be seen that the motion data is sampled once every 100 ms.

Although not shown, the sampled motion data is 16 bits. Then, an average of five motion data d ₁ , d ₂ , d ₃ , d ₄ and d ₅ generated over a 500 ms interval is calculated. Since the motion data is 16 bits, the calculated average is also 16 bits, where only the upper 8 bits are left and the lower 8 bits are discarded.

According to this, 8 bits are generated in the 500 ms interval. As shown in FIG. 3A, since the timer interval is divided into 16 500 ms intervals, a total of 128 bits (= 16 * 8 bits) are listed in the timer interval. The 128 bits listed are the keys.

4. Mobile device

As shown in FIG. 4, the mobile device 100 according to the present embodiment includes a touch screen 110, a sensor 120, a controller 130, a storage 140, and a communicator 150.

The touch screen 110 functions as a display means for displaying a cooperative pairing process, a cooperative process, and a GUI required therefor, as well as a user interface means for receiving a user command through the displayed GUI.

The sensor 120 detects movement of the mobile device 100 and generates movement data. The motion data generated by the sensor 120 is stored in the storage 140.

The controller 130 includes a GUI processor 131, a timer 133, an encryption / decryptor 135, and a collaboration processor 135.

The GUI processor 131 generates a GUI and displays the GUI on the touch screen 110, thereby receiving and processing a user command.

The timer 133 operates for a predetermined time when the motion detection of the mobile device 100 starts through the sensor 120 to set a timer section.

The encryption / decryption unit 135 generates a key using the motion data stored in the storage unit 140 and stores the generated key in the storage unit 140. In addition, the encryption / decryption unit 135 encrypts data to be transmitted to another mobile device through the communication unit 150 using a key stored in the storage unit 140. In addition, the encryption / decryption unit 135 decrypts data received from another mobile device through the communication unit 150 using a key stored in the storage unit 140.

The collaboration processor 135 processes processes required for collaboration.

The storage 140 provides a storage space for storing the movement data and the key. In addition, the communication unit 150 is connected to communicate with other mobile devices, and enables data transmission and reception.

5. Variant

So far, the present invention has been described in detail with reference to preferred embodiments of a pairing method for collaboration of a mobile device and a mobile device capable of performing the same.

In the above embodiment, it is assumed that data transmitted between the mobile devices 100-1 and 100-2 is encrypted / decrypted with a key generated using motion data, but this is merely an example for convenience of description. It is possible not only to perform encryption / decryption, but also to encrypt with a key other than the above key.

In addition, a specific method of generating a key using motion data is also only an example for convenience of description. It is also possible to implement a key generation in a different way than mentioned. That is, it is possible to implement to generate the key through a combination or calculation other than the average of the motion data. In the above embodiment, it is assumed that only the upper bits of the motion data are left and the lower bits are discarded. However, the remaining part and the discarding part of the motion data may be changed.

In the above embodiment, it is assumed that two mobile devices collaborate, but the technical idea of the present invention may be applied to three or more mobile devices collaborating.

In addition, it is also possible to perform collaborator registration by exchanging motion data itself instead of a key generated based on the motion data and determining a match.

In addition, the touch screen 110 may be replaced with another type of input / output device.

In addition, while the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above, but the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
