Description

[0001] Apparatus and method for generating wearable device password [0002]

The present invention relates to an apparatus and method for generating a password of a wearable device, and more particularly, to a wearable device for wearable wearable wearable devices, which is equipped with a plurality of pressure sensors, And a method thereof.

In recent years, wearable devices such as smart watches, smart bands, smart glasses, etc. have been inferior to smartphones due to the narrowness of the display and the inconvenience of the input interface.

In addition, as personal information and health information collected using a push alarm of a smart phone or a wearable device linked to a wearable device increase, the importance of personal information protection for a smart wearable device is increasing.

Most of the wearable devices that are launched today connect with the smartphone through the wireless LAN to collect personal information of the user, as well as push alarms from the smartphone. However, each security section is vulnerable and security is often not achieved even in the wearable device itself.

For example, password input function is not provided except for Apple watch of Apple and wearable device of Samsung's Tizen OS, and smart band product without display is not secured against wearable device itself.

The Apple Watch or Gear S2 uses a 10-digit number to generate and input a 4-digit password. In addition, it also has a Fat Finger problem that causes an error when entering a password due to a small screen, and also causes the user to steal over the shoulder There is also a security vulnerability against view attacks.

More specifically, A method of inputting a password by using the most commonly used 10-digit number is to input a numerical screen on a small display screen and input it from a user.

 This method can cause inconvenience and error in the input of the password depending on the narrowness of the screen and the size of the finger. In addition, since the 4-digit password is inputted, it is possible to combine 10000 passwords, There are disadvantages.

On the other hand, in the case of a wearable device in which there is no display, a wearable device without a display has no way of interacting with a user, and thus merely collects activity information and biometric information of a user when wearing a smart band. Since the user 's biometric information is also personal information, a method that can protect it even in the primary collection is needed.

And, in another way, It is the most popular password input method in smartphone with built-in Android OS and it is a way to draw pattern using 9 points. Patterns can be created by connecting a minimum of 4 points to a maximum of 9 points. It is possible to generate patterns from a minimum of 1400 to a maximum of 32256 patterns. It is more secure than the password input method using 10 digits, but it is vulnerable to attack over the shoulder

Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like numbers refer to like elements throughout.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions in the embodiments of the present invention, which may vary depending on the intention of the user, the intention or the custom of the operator. Therefore, the definition should be based on the contents throughout this specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a password generating apparatus and method of a wearable device according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a password generating apparatus for a wearable device according to the present invention.

1, the apparatus for generating a password of a wearable device according to the present invention includes a plurality of pressure sensors 10, 10-1, ..., 10-n, a control unit 20, a storage unit 30, Unit 40, and a communication unit 50. [0034]

The plurality of pressure sensors 10, 10-1, ..., 10n are mounted at different positions on the outside of the wearable device, respectively. The pressure sensors 10, 10-1, .

An example of mounting positions of the plurality of pressure sensors 10, 10-1, ..., 10-n will be described in detail with reference to FIG.

2 is a view showing an example of a mounting position of the pressure sensor shown in Fig. 1 in different types of wearable devices.

As shown in Fig. 2, let us consider a case where the wearable device is a smart watch, an eyeglass frame, and a band. In the following description, it is assumed that there are three pressure sensors.

Basically, each of the pressure sensors 10, 10-1, ..., 10-n is a sensor capable of recognizing a touch intensity by a user and should be attached at a position capable of distinguishing touch intensity of a user, One at the bottom and two at the top, and the eyeglass frame in a row, it can be attached to a convenient location for the user to use as an input interface.

For example, in the case of a band in which a smart watch and a display device are not present as shown in FIGS. 2A and 2C, the pressure sensors 10, 10-1, ..., 10- By attaching one at the bottom of the band and two at the top of the band in consideration of the use, both the right hand and left arm users can easily implement the touch using the band.

In the case of a wearable device having an eyeglass frame structure as shown in FIG. 2 (b), three sensors may be arranged in a row in consideration of finger detection, stop, It is preferable that the position of the sensor can control the intensity of the pressure.

The controller 20 shown in FIG. 1 stores the sensing input values input from the plurality of pressure sensors 10, 10-1, ..., 10-n in the storage unit 30 according to the user's selective touch input. Compares the sensed input value with the defined threshold, and distinguishes the sensed input value by the set step.

The control unit 20 generates a primary secret number by combining the divided sensing input values and stores the generated primary secret number in the storage unit 30. Alternatively, each of the sensing input values corresponding to each sensing input value The pattern values stored in the storage unit 30 corresponding to the sensing values input from the pressure sensors 10, 10-1, ..., 10-n are combined and stored in the storage unit 30, You can also generate a secondary password.

Here, the sensing input values of each step defined in the storage unit 30 will be described in more detail.

It is possible to use a method of dividing the range of the sensing value input from the plurality of pressure sensors 10, 10-1, ..., 10-n into strong / approximately two levels. For example, if the resistance value (0 to 1023) input from each pressure sensor 10, 10-1, ..., 10-n is divided into three levels, 0 means no input, 1-99 means weak input, 100 The above values are divided into strong input. Using these separated values, six pressure sensors can produce six input values. For example, it can be divided into 6 input values as "pressure sensor 1_power / pressure sensor 1_power / pressure sensor 2_power / pressure sensor 2_power / pressure sensor 3_power / pressure sensor 3_power" .

That is, since each pressure sensor 10, 10-1, ..., 10-n can recognize two or three or more simultaneous inputs, the input values can be defined as follows.

1. Input sensor 1_ weak = ○

2. Input sensor 1_strength = ●

3. Input sensor 2_Application = △

4. Input sensor 2_Strength = ▲

5. Input sensor 3_ approx. = □

6. Input sensor 3_Strength = ■

When the sensor values inputted from the pressure sensors 10, 10-1, ..., 10-n are defined as above, the inputted sensor values can be generated as a password by combining them as follows.

1. One input:? = A /? = B /? = C /? = D /? = E /? = F

2. Two inputs:? = G /? = H /? = I /? = J /? = K /

3. Input three: ○ △ □ = M / ● ▲ ■ = N

Here, it is excluded that the pressure sensor 10, 10-1, ..., 10-n inputs the strength / weakness separately during simultaneous input. For example, the combination of the index finger and the thumb is not only confusing to the user, but also difficult to input. Therefore, the total number of combinations that can be input by using three sensors is 14, and combinations of 14 or more can be formed by combining 3 or more digits. Accordingly, the number of passwords generated according to the 4-digit pin input according to the conventional art and the number of generated passwords according to the pattern input are different as shown in Table 1 below.

Invention 4 digit PIN Enter pattern 3 digits 2,744 1,000 - 4 digits 38,416 10,000 1,400 5 digits 537,824 100,000 5,184 6 digits 7,529,536 1,000,000 16,032 7 digits 105,413,504 10,000,000 35,328 8 digits 1,475,789,056 100,000,000 49,536 9 digits 20,661,046,784 1,000,000,000 32,256

When the primary password is generated and stored in the storage unit 30 through the above method, the controller 20 inputs the secondary password for generating the final password through the output unit 40 You can ask the user. Here, in the case of the smart watch having the display device, the output unit 40 may request a password input on the screen as text, vibration, and sound, and when there is no display device such as a smart band or smart frame, The speaker may be required to input a secondary password by vibration or sound (voice).

If the user inputs the secondary password using the plurality of pressure sensors 10, 10-1, ..., 10-n in the same manner as described above, the control unit 20 uses the above- And compares the generated secondary password with the primary password previously stored in the storage unit 30 to determine whether they are the same.

If the primary password and the secondary password are equal to each other, the control unit 20 controls the output unit 40 to notify the user that the password has been matched. And stores the generated final password in the storage unit 30 or transmits the generated final password to the portable terminal connected to the wearable device via the communication unit 50 by short range wireless communication and stores the generated final password.

However, if the primary password and the secondary password do not coincide with each other, the control unit 20 can notify the user through the output unit 40 that the passwords do not match and request the password again.

Then, when a password is inputted by using the pressure sensors 10, 10-1, ..., 10-n from the user when the wearable device is driven, the input password is compared with the password finally generated and stored in the storage unit 30 And the user authentication is performed according to the result.

The method of generating a password according to the present invention corresponding to the operation of the password generating device of the wearable device according to the present invention will be described step by step with reference to FIG.

3 is a flowchart illustrating a method of generating a password of a wearable device according to the present invention.

As shown in FIG. 3, step reference values and pressure sensor input sensor values of pressure intensities for a plurality of pressure sensors are defined and stored in the wearable device, respectively (S301). Here, the detailed definitions of the input sensor values for each pressure sensor and for each step are described in detail above, and a detailed description thereof will be omitted.

If the user's touch sensors are sequentially input from the respective pressure sensors for generating the password (S302), the sensed values are sequentially compared with the reference values of the stored pressure intensities of the respective pressure sensors (S303 ).

According to the comparison result, the pre-defined input sensor values of the respective sensing values for the input pressure sensors are respectively mapped, and the input sensor values of the mapped respective pressure sensors are combined to generate and store the primary secret number (S304 ).

When the primary secret number is generated and stored, the user may be requested to input a secondary secret number to generate the final secret password (S305). In the case of a wearable device in which a display device such as a band or an eyeglass frame does not exist, a request for inputting the secondary password may require a password input in the form of text, vibration, and sound on the screen in the case of a smart watch having a display device. Or as a speaker, it may be required to input a secondary password by vibration or sound (voice).

In response to the request, if the sequential sensed values are input from the respective pressure sensors by using the touch of the pressure sensor in the same manner as described above, the secondary password is generated in the same manner as in steps S303 and S304 (S306) .

Next, in step S307, it is determined whether the primary password generated in step S304 is identical to the secondary password generated in step S306.

As a result of the comparison, if the primary password and the secondary password are identical to each other, the user is notified that the password is matched, and the password is generated and stored as the final password (S308). Here, the generated final password can be transmitted to the portable terminal connected to the wearable device via the local area network in short-range wireless communication, and stored.

However, if the primary password and the secondary password do not coincide with each other, the user can be informed that the passwords do not match and request re-entry of the secondary password.

Thereafter, when a password is input using the pressure sensors from a user when the wearable device is driven, the input password is compared with the password generated and stored finally, and the user authentication is performed according to the comparison result. Here, after the final password is generated, the user authentication method by inputting the password is performed according to whether or not the password inputted through the above method matches the set password, and the detailed description will be omitted.

In the above embodiments, only a method of generating a password in accordance with the touch strength of a plurality of pressure sensors is mentioned. However, a password is generated according to the input of the pressure sensor based on the strength and the touch time interval of the pressure sensor, It should be understood that it may also be created.

If the user authentication using the wearable device according to the present invention can be transmitted using secure communication, it can be used in a 3 ^rd Party program or a system. For example, when authentication is required in a billing system, the user can be authenticated through a wearable device rather than a complicated authentication method such as an authentication certificate or a cellular phone authentication, and then transmitted to another system.

As described above, the apparatus and method for generating the password of the wearable device according to the present invention have been described with reference to the embodiments. However, the scope of the present invention is not limited to the specific embodiments, And various modifications, alterations, and changes may be made without departing from the spirit and scope of the invention.

Therefore, the embodiments described in the present invention and the accompanying drawings are intended to illustrate and not to limit the technical spirit of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments and the accompanying drawings . The scope of protection of the present invention should be construed according to the claims, and all technical ideas within the scope of equivalents should be interpreted as being included in the scope of the present invention.
