  FIG. 3 is a diagram for explaining functions provided in the mobile terminal 1. In the mobile terminal 1, an authentication seed composed of at least one authentication information is registered in advance for each type of vibration, and when performing personal authentication as a means realized by an application program that operates the processor of the mobile terminal 1, A process for determining the type of vibration to be generated by the random number before the user inputs authentication information for each number of input operations that the user inputs input information used for verification, and an authentication seed corresponding to the determined type of vibration Authentication processing is performed, and a personal authentication sequence generating means 10 is generated for generating a personal authentication sequence in which the determined vibration type and authentication information are described in association with the number of input operations. By changing the type of vibration and authentication information for each user authentication, the authentication information can be stolen by visual inspection of the input operation or visual inspection of the display. It has prevented that is.

  In addition, when the personal authentication sequence generation unit 10 generates the personal authentication sequence, the mobile terminal 1 refers to the personal authentication sequence and inputs information input by the user after generating a type of vibration corresponding to the number of input operations. After executing the processing to obtain as information for each number of input operations described in the personal authentication sequence, the authentication information described in the personal authentication sequence and the number of input operations described in the personal authentication sequence The personal information authenticating means 11 that determines that the personal authentication is successful when the input information acquired from the user is collated and all the pieces of input information obtained from the user are successfully collated. Specifying authentication information entered by the user and verifying the identity by verifying the input information entered by the user

  In addition, the mobile terminal 1 registers an authentication seed corresponding to the vibration type for each set vibration type so that an authentication seed composed of at least one authentication information can be registered in advance for each vibration type. The registration means 12 is provided.

  FIG. 4 is a diagram for explaining the operation of the mobile terminal 1 when performing personal authentication.

  When an operation for unlocking is performed (for example, an operation of sliding a button for unlocking with a finger), personal authentication is started in the mobile terminal 1. When personal authentication is started, first, a personal authentication sequence generation of the mobile terminal 1 is generated. The means 10 operates, and the personal authentication sequence generation means 10 of the mobile terminal 1 generates a personal authentication sequence used for the current personal authentication (S1).

  FIG. 5 is a diagram for explaining the operation of the mobile terminal 1 when generating the personal authentication sequence. When the personal authentication sequence generation means 10 of the portable terminal 1 generates the personal authentication sequence used for the current personal authentication, first, the number of input operations is set to “1” (S10), and then a random number is generated (S11). ), The type of vibration corresponding to the number of input operations is determined based on random numbers (S12).

  The type of vibration used for personal authentication is preset in the personal authentication sequence generation means 10, and the personal authentication sequence generation means 10 generates a random number that matches the number of types of vibration set in the personal authentication sequence generation means 10. The type of vibration is determined based on the generated random number.

  For example, if the type of vibration used for personal authentication is presence / absence of vibration, two types of vibration corresponding to the presence / absence of vibration, “no vibration” and “vibration” are registered in the mobile terminal 1 to generate a personal authentication sequence. The means 10 generates a random number having a value of “0” or “1”. Then, when “no vibration” corresponds to “0” and “vibration” corresponds to “1”, the personal authentication sequence generation unit 10 determines that the vibration corresponding to the number of inputs is the random number value “1”. The type of is determined as “with vibration”.

  If the type of vibration used for personal authentication is the number of times of vibration, the type of vibration corresponding to the number of times of vibration is set, and if the maximum value of the number of times of vibration used for personal authentication is “3”, the personal authentication sequence generation means 10 A random number having a value of “0”, “1”, or “2” is generated. If “one vibration” corresponds to “0”, “two vibrations” corresponds to “1”, and “three vibrations” corresponds to “2”, the personal authentication sequence generation unit 10 determines the value of the random number. If “1”, the type of vibration corresponding to the number of times of input is determined as “twice vibrations”.

  When the personal authentication sequence generation means 10 of the mobile terminal 1 determines the type of vibration using the generated random number, it determines authentication information from the authentication seed corresponding to the determined type of vibration (S13), and determines the type of vibration and the authentication. Information is described in the personal authentication sequence in association with the number of input operations (S14).

  The content that the personal authentication sequence generation means 10 of the mobile terminal 1 determines the authentication information depends on the authentication seed registered in the mobile terminal 1. The authentication seed is information composed of at least one authentication information, and an example of an authentication seed composed of a plurality of authentication information is a password. Moreover, an image and a finger locus are given as examples of authentication seeds configured by a single piece of authentication information.

  For example, when using an authentication seed (in this case, a password) composed of a plurality of authentication information, a password having the same length is registered in advance for each type of vibration used for personal authentication, and the maximum number of input operations is the password length. become. And the personal authentication sequence generation means 10 of the portable terminal 1 respond | corresponds to the frequency | count of input operation from the character contained in the password corresponding to the kind of vibration determined by the random number as authentication information corresponding to the frequency | count of input operation. Extract the first character.

  Further, when using an authentication seed (here, an image or a finger trajectory) configured by a single piece of authentication information, the personal authentication sequence generation means 10 of the mobile terminal 1 uses a random number as authentication information corresponding to the number of input operations. An image or finger trajectory corresponding to the type of vibration determined by the above is extracted.

  When the personal authentication sequence generation means 10 of the portable terminal 1 stores the type of vibration and the authentication information in association with the number of input operations, the number of input operations is incremented by one (S15). If the number of times does not exceed the preset maximum number of input operations (S16), the process returns to S11 in FIG. 5, and the number of input operations after the increment exceeds the preset maximum number of input operations. If so, the procedure of FIG.

  Returning to the description of FIG. When the personal authentication sequence generation means 10 of the mobile terminal 1 generates the personal authentication sequence, the personal authentication means 11 of the mobile terminal 1 operates, and the personal authentication means 11 of the mobile terminal 1 starts the number of input operations from “1”. A loop process (S2) is repeatedly executed until the maximum number of input operations is reached.

  In this loop process (S2), the personal authentication means 11 of the portable terminal 1 refers to the personal authentication sequence and generates a type of vibration corresponding to the number of input operations of the loop process (S2) (S3). Information input by the user is acquired as input information (S4), and processing for storing the input information acquired from the user in association with the number of input operations in the loop process (S2) is performed.

  When the loop process (S2) is completed, the personal authentication unit 11 of the mobile terminal 1 refers to the personal authentication sequence, and inputs the authentication information described in the personal authentication sequence and the input information acquired from the user for each input operation. Collation (S5), if all the input information acquired from the user is successfully collated, it is determined that the personal authentication has succeeded (S6), and if there is at least one input information that has failed in collation, it is determined that the personal authentication has failed. Then (S7), the procedure of FIG.

  If the authentication seed is registered for each type of vibration, the number of authentication seeds that the user must remember increases. Therefore, the type of vibration that does not register the authentication seed is provided, and the number of authentication seeds that the user must remember Can be reduced.

  When providing a vibration type that does not register an authentication seed, the personal authentication sequence generation means 10 of the mobile terminal 1 determines a vibration type corresponding to the number of input operations using a random number, and the authentication seed corresponds to the determined vibration type. If not attached, the information associated with the number of input operations is limited to the type of vibration.

  And when the personal authentication means 11 of the portable terminal 1 collates the authentication information described in the personal authentication sequence with the input information acquired from the user for each number of input operations, the authentication information is associated with the number of input operations. If not, if the input information is other than the authentication information determined from the authentication seed registered in the mobile terminal 1, it is determined that the verification is successful.

  From here, the registration means 12 of the portable terminal 1 will be described. In the present embodiment, the registration unit 12 of the mobile terminal 1 sets each authentication type set in the mobile terminal 1 so that an authentication seed composed of at least one authentication information can be registered in advance for each type of vibration. A form for allowing the user to set an authentication seed corresponding to the vibration type is displayed, and the user can register an authentication seed corresponding to the vibration type.

  For example, if the authentication seed is a password, the form that allows the user to set the authentication seed corresponding to the vibration type is a form for entering the password, and if the authentication seed is an image, it is registered in advance for use as an authentication seed. The form allows the user to select an authentication seed corresponding to the type of vibration from the plurality of images.

  From here, the specific example of the portable terminal 1 which concerns on this embodiment is demonstrated.

(Embodiment 1)
From here, the first embodiment will be described. The first embodiment is a mode in which the type of vibration is the presence / absence of vibration and the authentication seed registered in the mobile terminal 1 is a password.

  When the type of vibration is set to presence or absence of vibration, there are only two types of vibration, “with vibration” and “without vibration”, and an authentication seed (here, image or finger trajectory) composed of one piece of authentication information is used. When used, only two pieces of authentication information are used for personal authentication. Therefore, in the first embodiment, a password which is an authentication seed composed of a plurality of pieces of authentication information (here, characters) is used.

  FIG. 6 is a diagram for explaining the first embodiment when setting an authentication seed for each type of vibration, FIG. 6 (a) is an example of setting a password, FIG. 6 (b) is an example of a personal authentication sequence, FIG. 6C is an image diagram of personal authentication.

  In FIG. 6A, a password corresponding to “vibration” and a password corresponding to “no vibration” are set. In FIG. 6A, the password length is 4 characters, and the password corresponding to “no vibration”. “0312” is set, and “1207” is set as the password corresponding to “with vibration”.

  Here, since the password length is 4 characters, the maximum number of input operations is four, and the personal authentication sequence generation means 10 of the mobile terminal 1 performs the first, second, third and fourth input operations respectively. , The type of vibration (in this case, either no vibration or with vibration) is determined based on the random number, and authentication information is further determined from the authentication seed corresponding to the determined type of vibration.

  Since the password is used as the authentication seed, the personal authentication sequence generation unit 10 of the mobile terminal 1 uses the characters included in the password corresponding to the type of vibration determined by the random number as authentication information corresponding to the number of input operations. The character of the character corresponding to the number of input operations is extracted from.

  In FIG. 6B, the vibration type corresponding to the first input operation is “with vibration”, the vibration type corresponding to the second input operation is “no vibration”, and the vibration corresponding to the third input operation. Since the type of vibration is determined to be “with vibration” and the type of vibration corresponding to the fourth input operation is determined to be “no vibration”, the authentication information corresponding to the first input operation is “with vibration”. The first character (here, “1”) is extracted from the characters included in the password (here, “1207”). Also, as authentication information corresponding to the second input, the second character (here, “3”) out of the characters included in the password (here, “0312”) corresponding to “no vibration”. Is extracted.

  In this way, by extracting authentication information corresponding to the number of input operations, the vibration type corresponding to the first input operation in the personal authentication sequence shown in FIG. The code is “1”, the vibration type corresponding to the second input operation is no vibration, the authentication code is “3”, the vibration type corresponding to the third input operation is vibration, and the authentication code is “0” The vibration type corresponding to the fourth input operation is “no vibration” and the authentication code is “2”.

  When performing personal authentication on the mobile terminal 1, vibrations of the type corresponding to the number of input operations occur according to the personal authentication sequence. Therefore, according to the personal authentication sequence of FIG. 6B, FIG. As shown, vibrations are generated during the first and third input operations.

  In FIG. 6, since the authentication seed is a password and the authentication information is a character extracted from the password, when acquiring authentication information corresponding to the number of input operations from the user, as shown in FIG. The personal authentication means 11 of the mobile terminal 1 displays a form for inputting characters on the touch panel 1g of the mobile terminal 1, acquires the characters input on the form as input information from the user, and then executes the personal authentication sequence. The authentication information described in the personal authentication sequence is compared with the input information acquired from the user for each number of input operations, and if the verification of all the input information is successful, it is determined that the personal authentication is successful.

  Specifically, in the personal authentication sequence of FIG. 6B, the authentication code corresponding to the first input operation is “1”, the authentication code corresponding to the second input operation is “3”, and the third input is performed. Since the authentication code corresponding to the operation is set to “0” and the authentication code corresponding to the fourth input operation is set to “2”, the input information input in the first input operation (here, Character) is “1”, the input information input in the second input operation is “3”, the input information input in the third input operation is “0”, and in the fourth input operation If the input information is “2”, it is determined that the personal authentication is successful.

  FIG. 7 is a diagram for explaining the first embodiment when a vibration type that does not register an authentication seed is provided. FIG. 7A is an example of setting a password, FIG. 7B is an example of a personal authentication sequence, and FIG. FIG. 7C is an image diagram of personal authentication.

  In FIG. 7A, a password corresponding to “no vibration” is not set, only a password corresponding to “no vibration” is set. In FIG. 7A, the password length is 4 characters, and “vibration” “0312” is set as the password corresponding to “None”.

  Here, since the password length is 4 characters, the maximum number of input operations is four, and the personal authentication sequence generation means 10 of the mobile terminal 1 performs the first, second, third and fourth input operations respectively. , The type of vibration (in this case, either no vibration or with vibration) is determined based on the random number, and authentication information is further determined from the authentication seed corresponding to the determined type of vibration.

  In FIG. 7A, since the password corresponding to “with vibration” is not registered, the personal authentication sequence generation means 10 of the portable terminal 1 determines the number of input operations when the vibration type is “without vibration”. When the character of the character corresponding to the number of input operations is extracted from the characters included in the password corresponding to the type of vibration determined by random numbers as the corresponding authentication information, and the type of vibration is “With vibration” The authentication information corresponding to the number of input operations is set to NULL indicating that there is no authentication information.

  In FIG. 7B, the vibration type of the first input operation is “with vibration”, the vibration type of the second input operation is “no vibration”, and the vibration type of the third input operation is “with vibration”. And, since the type of vibration of the fourth input operation is determined as “no vibration”, the authentication information corresponding to the first and third input operations is NULL, and the second and fourth times. As the authentication information corresponding to the input operation, the character corresponding to the number of input operations is extracted from the characters included in the password corresponding to “no vibration” (here, “1207”).

  Thus, by extracting authentication information corresponding to the number of input operations, the type of vibration corresponding to the first input operation in the personal authentication sequence illustrated in FIG. 7B is “with vibration”. The authentication information is NULL, the vibration type corresponding to the second input operation is “no vibration”, the authentication information is “3”, and the vibration type corresponding to the third input operation is “vibration”. The information is NULL, the type of vibration corresponding to the fourth input operation is “no vibration”, and the authentication information is “2”.

  When performing personal authentication on the mobile terminal 1, vibrations of a type corresponding to the number of input operations are generated according to the personal authentication sequence. Therefore, according to the personal authentication sequence of FIG. 7B, FIG. As shown, vibration is generated in the first and third input operations.

  In FIG. 7, the password corresponding to “with vibration” is not registered, so that the personal authentication unit 11 of the mobile terminal 1 inputs the authentication information described in the personal authentication sequence and the input information acquired from the user the number of input operations. When verification information is not associated with the number of input operations for each verification, it is determined that verification is successful if the input information is other than authentication information determined from the authentication seed registered in the mobile terminal 1 Will do.

  Specifically, in the personal authentication sequence in FIG. 7B, the authentication code corresponding to the first input operation is set to NULL, so that it is registered in the mobile terminal 1 as shown in FIG. 7C. The character corresponding to the first input (here, “0”) is extracted from the password corresponding to “no vibration” as the authentication seed, and the character input by the user in the first input operation is “0”. If it is other than “”, it is determined that the collation is successful.

  Further, in the personal authentication sequence of FIG. 7B, the authentication code corresponding to the second input operation is set to “3”. Therefore, as shown in FIG. If the inputted character is “3”, it is determined that the collation is successful.

  Since the authentication code corresponding to the third input is set to NULL, as shown in FIG. 7C, from the password corresponding to “no vibration” as the authentication seed registered in the mobile terminal 1, The character of the character corresponding to the third input operation (here, “1”) is extracted, and if the character input by the user in the third input operation is other than “1”, it is determined that the verification is successful. It will be.

  Further, in the personal authentication sequence in FIG. 7B, the authentication code corresponding to the fourth input operation is set to “2”, so that the user in the fourth input operation as shown in FIG. 7C. If the input character is “2”, it is determined that the collation is successful.

(Embodiment 2)
From here, 2nd Embodiment is described. In the second embodiment, the type of vibration is the number of vibrations, and the authentication information is an image. When the type of vibration is the number of vibrations, the number of types of vibration can be arbitrarily set according to the number of vibrations. Therefore, in the second embodiment, an image that is an authentication seed composed of one piece of authentication information is used. Yes.

  FIG. 8 is a diagram for explaining Embodiment 2 when setting authentication information for each type of vibration, FIG. 8A is an example of setting an image, FIG. 8B is an example of a personal authentication sequence, FIG. 8C is an image diagram of personal authentication.

  As shown in FIG. 8A, when the type of vibration is the number of vibrations and the authentication information is an image, an image corresponding to each number of vibrations is set. The number of vibrations is set in the mobile terminal 1 in advance. In FIG. 8A, the number of vibrations is “1 vibration”, “2 vibrations”, and “3 vibrations”. The image of the child is set with the image of the zodiac kite for “twice vibrations” and the image of the zodiac kite for “three times vibration”.

  When an image is used as the authentication seed, the maximum number of input operations can be arbitrarily set, and is four here.

In FIG. 8B, the number of vibrations corresponding to the first input operation is “vibration twice”, and the number of vibrations corresponding to the second input operation is “vibration once”, corresponding to the third input operation. Since the number of vibrations to be performed is “3 times vibration” and the number of vibrations corresponding to the fourth input operation is determined to be “one vibration”, the authentication information corresponding to the first input operation is “ An image of the eyelid corresponding to “vibration twice” is extracted. In addition, a child image corresponding to “one vibration” is extracted as authentication information corresponding to the second input operation.

  In this way, by extracting authentication information corresponding to the number of input operations, as shown in FIG. 8B, the personal authentication sequence has the number of vibrations corresponding to the first input operation as “ “Vibration 2 times”, authentication information is 丑 image, number of vibrations corresponding to second input operation is “vibration 1 time”, authentication information is child image, number of vibrations corresponding to third input operation Is “vibration 3 times”, the authentication information is a bag image, the number of vibrations corresponding to the fourth input operation is “vibration 1 time”, and the authentication information is a child image.

  When the personal authentication is performed by the mobile terminal 1, a vibration corresponding to the number of input operations is generated with reference to the personal authentication sequence. Therefore, according to the personal authentication sequence of FIG. ), The first input operation generates vibration twice, the second input operation generates vibration once, the third input operation generates vibration three times, and In the fourth input operation, vibration occurs once.

  In FIG. 8, since the authentication seed and the authentication information are images, when acquiring the authentication information corresponding to the number of input operations from the user, as shown in FIG. 8C, the personal authentication of the mobile terminal 1 is performed. The means 11 selects several images randomly selected without overlapping from images registered in the mobile terminal 1 so as to exclude images corresponding to the number of input operations and images corresponding to the number of input operations ( Here, three images are displayed on the display of the portable terminal 1, the image selected by the user is acquired from the user as input information, and the authentication information described in the authentication sequence is referred to by referring to the authentication sequence. And the input information acquired from the user are collated for each number of input operations, and if the collation of all the input information is successful, it is determined that the personal authentication is successful.

  Specifically, in the personal authentication sequence of FIG. 8B, the authentication code corresponding to the first input operation is input to the bag image and the authentication code corresponding to the second input operation is input to the child image for the third time. Since the authentication information corresponding to the operation is set to the image of 寅 and the authentication information corresponding to the fourth input operation is set to the child image, the authentication information input by the first input operation is the image of 丑Then, the input information input in the second input operation is a child image, the input information input in the third input operation is a spider image, and the input information input in the fourth input operation is If it is a child image, it is determined that the personal authentication is successful.

  FIG. 9 is a diagram for explaining the second embodiment when a type of vibration in which no authentication seed is registered is provided. FIG. 9A is an example of setting an image, FIG. 9B is an example of a personal authentication sequence, and FIG. FIG. 9C is an image diagram of personal authentication.

  In FIG. 9A, images corresponding to “vibration 2 times” and “vibration 3 times” are not registered, and only images corresponding to “vibration 1 time” are registered. In FIG. The image of the child of the zodiac is registered in “Vibration once”.

  When an image is used as the authentication seed, the maximum number of input operations can be arbitrarily set, and is set to 4 here. The personal authentication sequence generation means 10 of the mobile terminal 1 determines the type of vibration for each of the first, second, third and fourth input operations based on the generated random number, and further supports the determined type of vibration. Authentication information is determined from the authentication seed to be used.

  Since the images corresponding to “2 times vibration” and “3 times vibration” are not registered, the personal authentication sequence generation unit 10 of the mobile terminal 1 performs the number of input operations when the type of vibration is 1 vibration. If the child image corresponding to the vibration type determined by the random number is extracted as the authentication information corresponding to the number of vibrations, and the vibration type is 2 vibrations and 3 vibrations, the authentication information corresponding to the number of input operations is the authentication information. Set to NULL to indicate that there is no

  In FIG. 9B, the number of vibrations corresponding to the first input operation is 2 vibrations, the number of vibrations corresponding to the second input operation is “vibration 1”, and the vibration corresponding to the third input operation. The number of times is determined as “3 times vibration” and the number of times of vibration corresponding to the fourth input operation is determined as “one vibration”, so that the authentication information corresponding to the first and third input operations is NULL. As the authentication information corresponding to the second and fourth input operations, a child image corresponding to “one vibration” is extracted.

  In this way, the authentication information corresponding to the number of input operations is extracted, and as shown in FIG. 9B, the personal authentication sequence is such that the number of vibrations corresponding to the first input operation is “ “Vibration 2 times”, the authentication information is NULL, the number of vibrations corresponding to the second input operation is “1 vibration”, the authentication information is the child image, the number of vibrations corresponding to the third time is “3 vibrations” The authentication information is NULL, the number of vibrations corresponding to the fourth input operation is “one vibration”, and the authentication information is a child image.

  When the personal authentication is performed by the mobile terminal 1, the personal authentication sequence is referred to, and the type of vibration corresponding to the number of input operations is generated. Therefore, according to the personal authentication sequence of FIG. ), The first input operation generates vibration twice, the second input operation generates vibration once, the third input operation generates vibration three times, and In the fourth input operation, vibration occurs once.

  In FIG. 9, since the images corresponding to “vibration twice” and “vibration three times” are not registered, the personal authentication means 11 of the mobile terminal 1 acquires the authentication information described in the personal authentication sequence and the user. When the input information is collated, if the authentication information is not associated with the number of input operations, the input information is other than the authentication information (here, the child image) determined from the authentication seed registered in the mobile terminal 1 If so, it is determined that the verification is successful.

  Specifically, in the personal authentication sequence of FIG. 9B, the authentication information corresponding to the first input operation is set to NULL, so that it is registered in the mobile terminal 1 as shown in FIG. 9C. A child image corresponding to “one vibration” is extracted as an authentication seed, and if the image selected by the user in the first input operation is other than the child image, it is determined that the verification is successful.

  Further, in the personal authentication sequence of FIG. 9B, the authentication information corresponding to the second input operation is set in the child image. Therefore, as shown in FIG. If the selected image is a child image, it is determined that the collation is successful.

  Since the authentication code corresponding to the third input is set to NULL, as shown in FIG. 9C, the child corresponding to “vibration once” is registered as the authentication seed registered in the mobile terminal 1. If an image is extracted and the image selected by the user in the third input operation is other than the child image, it is determined that the collation is successful.

  Further, in the personal authentication sequence in FIG. 9B, the authentication information corresponding to the fourth input operation is set in the child image, so that the user in the fourth input operation as shown in FIG. 9C. If the selected image is a child image, it is determined that the collation is successful.
