Description

  The present invention relates to an authentication system, an authentication method, a data control apparatus, and a program thereof, and more particularly, to an authentication system, an authentication method, a data control apparatus, and a program thereof using a device status check.

  An example of a conventional authentication method is described in Patent Document 1. This conventional authentication method includes the ITV control device and the operation content comparison device and operates as follows. The ITV control device compares the input password with a previously registered password. If the input password is correct, the subsequent operation input is accepted. The operation content comparison device determines whether the current operation content is a normal operation on the basis of the operation content for a certain period for each operation account stored in the memory, and performs processing when it is determined that the current operation content is a normal operation. Continue (access is authenticated).

  Other examples of conventional authentication methods are described in Patent Document 2 and Patent Document 3. In this conventional authentication method, an individual is authenticated based on a user's practice, such as a keyboard pressing timing when inputting a password and a mouse click timing / movement locus pattern.

Next, the configuration of the first exemplary embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing the configuration of the first embodiment of the present invention.
FIG. 2 is a diagram illustrating an example of the device state information storage unit.
FIG. 3 is a diagram illustrating an example of the user information storage unit.

  In the first embodiment of the present invention, a speaker is used as a device.

  Referring to FIG. 1, the first embodiment of the present invention includes a data control device 2, an input device 1, an output device 3, a speaker 4, and a storage device 5 that operate by program control.

  The data control apparatus 2 includes a device state analysis unit 21 and an authentication unit 22.

  The speaker 4 includes a state setting unit 41 and a state notification unit 42.

  The storage device 5 holds information (user ID, password, device type, device status information, etc.) necessary for authentication. The storage device 5 includes a device state information storage unit 51 and a user information storage unit 52.

  Each of these devices generally operates as follows.

  The device status information storage unit 51 stores information on the device to be checked. The information regarding the device to be checked includes a user ID, a device type to be checked, a state to be checked, and a check value. In the device state information storage unit 51, information on a device to be checked is stored in advance by a device state information storage unit (not shown). An example of the device state information storage unit 51 is shown in FIG. Referring to FIG. 2, for the user ID “aaaaaa”, the device type to be checked is “speaker”, the state to be checked is “volume”, and the check value is “2”.

  The user information storage unit 52 stores a correspondence between a user ID (identifier) and a password. FIG. 3 shows an example of the user information storage unit.

  The input device 1 includes input means such as a keyboard and a mouse for inputting characters and the like, and display means such as a display for displaying an authentication information input screen from the data control device 2. The authentication information input screen includes a user ID input field and a password input field. The input device 1 inputs a user ID and a password from a keyboard, a mouse, or the like on the authentication information input screen. The input user ID and password are passed to the authentication unit 22 via the device state analysis unit 21.

  The device state analysis means 21 receives a user identifier and a password from the input device 1. Then, the device type to be checked by the user ID and the state to be checked are read and acquired from the device state information storage unit 51. Then, based on the acquired device type (speaker 4 in this example) and the state to be checked (volume in this example), the state value is acquired from the state notification means 42. Then, the acquired device type, status, and setting value are passed to the authentication unit 22.

  The state setting means 41 sets and holds the state of the speaker 4. For example, a volume adjustment knob or the like is provided, and the user sets the volume of the speaker 4 with the volume adjustment knob or the like, and the state setting means 41 holds the set value.

  The state notification unit 42 acquires the set value of the state designated from the device state analysis unit 21 from the state setting unit 41 and notifies the device state analysis unit 21 of the set value. For example, the value of the volume of the speaker 4 is notified. Note that the status notification unit 42 may be configured by a driver (firmware or the like), for example.

  The authentication unit 22 compares the user ID and password acquired from the user information storage unit 52 with the user ID and password passed from the device state analysis unit 21. If they match, the password authentication is successful. When the password authentication is successful, information (device type, device state, and check value thereof) necessary for authentication is acquired from the device state information storage unit 51. Then, the device type, device status, and the check value acquired from the device status information storage unit 51 are compared with the device type, status, and the set value passed from the device status analysis unit 21, and if they match, the authentication is successful. And

  The output device 3 displays the authentication result. If authentication is not possible, an error message is displayed. Even if the password is correct, if the status of the target device (speaker 4) is incorrect, “password is incorrect” is displayed.

Next, the operation of the first embodiment of the present invention will be described in detail with reference to FIGS.
FIG. 4 is a diagram showing the flow of operation of the first embodiment of the present invention.

  It is assumed that the contents of the device state information storage unit 51 are as shown in FIG. 2, and the contents of the user information storage unit 52 are as shown in FIG.

  First, a user ID and a password are input from the input device 1 (step A1 in FIG. 4). In this example, the volume of the speaker 4 is set to “2”, “aaaaaa” is input as the user ID, and “Password” is input as the password.

  The device state analysis unit 21 acquires the device type (speaker in this example) to be checked with the user ID and the state to be checked (volume in this example) from the device state information storage unit 51 (step in FIG. 4). A2), the setting value of the state of the target device (in this example, the setting value of the volume of the speaker 4) is acquired (step A3 in FIG. 4).

  The authentication unit 22 acquires information (user ID, password, device type to be checked, status to be checked, and check value) necessary for authentication from the device status information storage unit 51 and the user information storage unit 52 (step in FIG. 4). A4).

  A password is compared and checked between the password input from the input device 1 and the password acquired from the user information storage unit 52 (step A5 in FIG. 4).

  A check is made by comparing the device state between the set value of the volume of the speaker 4 acquired by the device state analysis means 21 and the check value of the volume of the speaker acquired from the device state information storage unit 51 (FIG. 4). Step A6).

  The information necessary for authentication of the input user ID is “password =“ Password ”” and “speaker volume =“ 2 ””, the volume of the speaker 4 is set to “2” and the password is set in step A1. Since “Password” is entered in “No”, there is no problem in either step A5 or step A6, and the authentication is successful (step A7 in FIG. 4).

  When there is a problem in step A5 or step A6 in FIG. 4 (that is, when a value other than “Password” is input as the password in step A1 or when the volume of the speaker 4 is set to other than “2”). Then, an authentication error “password is incorrect” is displayed on the output device 3 (step A8 in FIG. 4).

  Next, effects of the first exemplary embodiment of the present invention will be described.

  In the first embodiment of the present invention, since the volume level of the speaker is referred to as one of the devices, whether or not the authentication is successful can be automatically determined based on the volume setting value when the password is input. . For legitimate users, authentication succeeds because they know the set volume that they registered, but authentication is difficult because it is impossible to know that the volume other than the user has an effect on the authentication. Become). Even if the device check determines that an error has occurred, the display content displays “Password is incorrect”. As a result, the third party does not know that an error has occurred in the device check.

Next, the configuration of the second exemplary embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 5 is a diagram showing the configuration of the second embodiment of the present invention.
FIG. 6 is a diagram illustrating an example of the device state information storage unit.

  In the second embodiment of the present invention, a display is used as a device.

  Referring to FIG. 5, the second embodiment of the present invention includes a data control device 6 that operates by program control, an input device 1, an output device 3, a display 7, and a storage device 8.

  The data control device 6 includes a device state analysis unit 61 and an authentication unit 22.

  The display 7 includes state setting means 71 and state notification means 72.

  The storage device 8 includes a device state information storage unit 81 and a user information storage unit 52.

  Each of these devices generally operates as follows.

  The device state information storage unit 81 is equivalent to the device state information storage unit 51 of the first embodiment described above. An example of the device state information storage unit 81 is shown in FIG. Referring to FIG. 6, for the user ID “aaaaaa”, the device type to be checked is “display”, the state to be checked is “luminance”, and the check value is “4”.

  The device state analysis unit 61 acquires the device type to be checked by the user ID and the state to be checked from the device state information storage unit 81. Then, based on the acquired device type (display 7 in this example) and the state to be checked (luminance in this example), the state value is acquired from the state notification means 72. Then, the acquired device type, status, and setting value are passed to the authentication unit 22.

  The state setting means 71 sets and holds the state of the display 7. For example, a brightness adjustment knob or the like is provided, and the user sets the brightness of the display 7 with the brightness adjustment knob or the like, and the state setting means 71 holds the set value.

  The state notification unit 72 acquires the set value of the state specified from the device state analysis unit 61 from the state setting unit 71 and notifies the device state analysis unit 61 of the set value. For example, the brightness value of the display 7 is notified. Note that the status notification unit 72 may be configured by a driver (firmware or the like), for example.

Next, the operation of the second embodiment of the present invention will be described in detail with reference to FIG. 3 and FIGS.
FIG. 7 is a diagram showing the flow of operation of the second embodiment of the present invention.

  It is assumed that the contents of the device status information storage unit 81 are as shown in FIG. 6, and the contents of the user information storage unit 52 are as shown in FIG.

  First, a user ID and a password are input from the input device 1 (step B1 in FIG. 7). In this example, the brightness of the display 7 is set to “4”, “aaaaaa” is input as the user ID, and “Password” is input as the password.

  The device state analysis unit 61 acquires from the device state information storage unit 81 the device type (display in this example) to be checked with the user ID and the state to be checked (in this example, luminance) (see FIG. 7). Step B2), the setting value of the state of the target device (in this example, the luminance setting value of the display 7) is acquired (Step B3 in FIG. 7).

  The authentication means 22 acquires information (user ID, password, device type to be checked, status to be checked, and check value) necessary for authentication from the device status information storage unit 81 and the user information storage unit 52 (step of FIG. 7). B4).

  A password is compared and checked between the password input from the input device 1 and the password acquired from the user information storage unit 52 (step B5 in FIG. 7).

  A check is made by comparing the state of the device between the set value of the brightness of the display 7 acquired by the device state analysis means 61 and the check value of the brightness of the display acquired from the device state information storage unit 81 (FIG. 7). Step B6).

  The information necessary for authentication of the input user ID is “password =“ Password ”” and “display brightness =“ 4 ””, the brightness of the display 7 is set to “4” in the above step B1, and the password is set. Since “Password” is entered in “No”, there is no problem in either step B5 or step B6, and the authentication is successful (step B7 in FIG. 7).

  When there is a problem in Step B5 or Step B6 in FIG. 7 (that is, when a value other than “Password” is input as the password in Step B1 or the brightness of the display 7 is set to other than “4”). Then, an authentication error “password is incorrect” is displayed on the output device 3 (step B8 in FIG. 7).

  Next, the effect of the second embodiment of the present invention will be described.

  In the second embodiment of the present invention, since the display brightness state is referred to as one of the devices, it is possible to automatically determine whether or not the authentication is successful based on the display brightness setting value when the password is input. . If the user is a legitimate user, the authentication is successful because he / she knows the set display brightness registered by himself / herself. However, authentication is difficult because it is not known that the display brightness affects the authentication except for the user. Success).

  That is, display brightness and speaker volume are usually not adjusted frequently (especially not changed much during login). For this reason, if a value different from the setting value that the user is normally using is set in the device status information storage unit in advance, it is difficult to match the authentication conditions and the effect of preventing unauthorized access is high (temporary only at login) To the display brightness and speaker volume set in the device status information storage unit).

Next, the configuration of the third embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 8 is a diagram illustrating examples of the device state information storage unit (a) and the user information storage unit (b).

  In the third embodiment of the present invention, a device check is linked to each character of the password to authenticate each character.

  The configuration of the third embodiment is equivalent to the configuration of the first embodiment described above (FIG. 1).

Next, the operation of the third embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 9 is a diagram showing the flow of operation of the third embodiment of the present invention.

  The contents of the device state information storage unit and the user information storage unit are as shown in FIG.

  First, “1” is set in the variable area i, and the user ID is input from the input device (step C1 in FIG. 9).

  The first character (i-th character) of the password is input from the input device (step C2 in FIG. 9). For example, when i = 1, the volume of the speaker 4 is set to “2”, and “x” is input as the first character of the password.

  The device state analysis means acquires the device type to be checked by the user ID and the state to be checked from the i-th in the device state information storage unit (step C3 in FIG. 9). For example, when i = 1, a speaker is acquired as a device type to be checked, and a volume is acquired as a check state.

  The setting value of the state of the target device is acquired (step C4 in FIG. 9). In this example, the setting value “2” of the volume of the speaker 4 is acquired.

  The authentication means acquires information (user ID, password, device type to be checked, status to be checked, and check value) necessary for authentication from the i-th and user information storage units of the device status information storage unit (step of FIG. 9). C5).

  The i-th character of the password is checked between the i-th character of the password input from the input device and the i-th character of the password acquired from the user information storage unit (step C6 in FIG. 9). For example, when i = 1, the information necessary for authentication of the input user ID is “password =“ x ””, and “x” is input as the password in step C 1, which matches. If not, the process proceeds to Step C11.

  The i th check of the device state is performed between the set value of the volume of the speaker 4 acquired by the device state analysis means and the check value of the speaker volume acquired from the i th of the device state information storage unit (FIG. 9). Step C7). For example, when i = 1, the information necessary for authentication of the input user ID is “speaker volume =“ 2 ””, and the volume of the speaker 4 is set to “2” in the above step C1. To do. If not, the process proceeds to Step C11.

  It is checked whether all characters of the password have been input (step C8 in FIG. 9). If all characters have not yet been input, “i = i + 1” is set (step C9 in FIG. 9), and the process returns to step C2.

  If all characters of the password have been entered, there is no problem with any of the checks, and the authentication is successful (step C10 in FIG. 9).

  Since there is a problem with any of the checks, an authentication error “password is incorrect” is displayed on the output device 3 (step C11 in FIG. 9).

  In this way, it is possible to make unauthorized authentication more difficult by linking a device check to each password.

  In the above-described embodiment, information (user ID, password, device type to be checked, status to be checked and check value) required for authentication is stored and managed separately in the device status information storage unit and the user information storage unit. ing. As another embodiment, information necessary for authentication may be collectively stored and managed in the device status information storage unit.

  In the above-described embodiment, one state of one device is checked and authenticated. As another example, a plurality of states of one device may be checked (see FIG. 10A), or a plurality of devices may be checked (see FIG. 10). b)). This makes it possible to make unauthorized authentication more difficult.

  In addition, when the password input timing is not known to anyone other than the authorized user (the password input screen etc. is not displayed), the device is automatically checked and nothing is done if it is not authenticated (for example, an error) You may make it self-loop without displaying a screen. In this way, authentication seems unnecessary, and in fact, by checking the device internally, it becomes possible to make unauthorized authentication even more difficult, and use other than authorized users can be prevented.

  In the above-described embodiments, the speaker or the display is described as the target device type. As another embodiment, not only a speaker and a display but also a hard disk drive, a USB memory, a USB accessory (light, fan, etc.) that can be connected by a USB (Universal Serial Bus) or the like may be used as the target device type. For example, when the device type is “USB memory”, “USB memory = connected as E drive” is set as the device state. Even if any device check determines that an error has occurred, “password is incorrect” is displayed on the output device as the error message display content. This has the effect of making it difficult for a third party to understand that an error has occurred in the device check.

  In the above-described embodiment according to the present invention, a program or the like for executing the processing operation of the data control device is recorded as data on a recording medium (not shown) such as a magnetic disk or a ROM of the data control device, The recorded data is read out and used to operate the data control device. As described above, the function of the data control apparatus can be realized by recording the data for operating the data control apparatus according to the present invention on the recording medium and installing the recording medium.

  INDUSTRIAL APPLICABILITY According to the present invention, the present invention can be applied to uses such as a laptop computer unauthorized use prevention device and a program (software license control, etc.) for realizing the unauthorized use prevention device on a computer. It can also be applied to uses such as prevention of unauthorized use of mobile phones and prevention of car theft.
