Description

  The present invention relates to a personal authentication method using an IC card.

  In the authentication of individuals using IC cards, in order to perform stricter authentication, not only authentication based on data that can be read from the IC card itself, but also a method of performing authentication in combination with data input by the individual at the time of authentication is known. It has been. This will be described with reference to FIG. FIG. 2 is a configuration diagram of conventional authentication. In FIG. 2, 101 is an IC card, 102 is an IC card reader, 103 is an authentication device, and in this example, it is composed of a personal computer 103a and an authentication data storage device 103b. Reference numeral 104 denotes a 10-key device.

Next, the operation when the user performs authentication will be described. The user holds the IC card 101 owned by the user over the IC card reader 102. Further, a predetermined number is inputted from the 10-key device 104. 102 and 104 send the read data to the authentication device 103. The authentication device 103 reads the authentication data corresponding to the user from the authentication data storage device 103b and collates it. If the collation result is correct, it is assumed that authentication has been completed.
Japanese Laid-Open Patent Publication No. 2000-145219 is known as a method in which data input by an operation by a user in addition to an IC card is used as an authentication means.
JP 2000-145219 A

  Such an authentication method is more reliable than the authentication using only an IC card, but it requires a device other than the IC card reader for inputting operation data at the time of authentication called a 10-key device. There is a problem that the price of the system to be used becomes expensive. Accordingly, an object of the present invention is to provide a method of inputting authentication input data using only an IC card reader.

  The present invention uses the timing of holding an IC card as a means for improving the authentication accuracy. Means for clearly indicating the timing of holding the card in the IC card reader, means for prompting the user to input according to the specified timing, and determining whether or not the held IC card is held at a specified timing The operator is authenticated together with the determination result.

  According to the present invention, accurate personal authentication can be realized without increasing the number of input devices other than the IC card reader.

  A first embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram showing the configuration of the first embodiment of the present invention. The same parts as those in FIG. In FIG. 1, reference numeral 301 denotes an IC card reader according to the present invention, which includes a sounding device 301a.

  Next, the operation will be described. When the operator performs authentication, the IC card 101 is first held over the IC card reader 301 first. At this time, the IC card reader 301 sends the data read from the IC card itself to the authentication device 103. Next, the operator holds the IC card over the IC card reader 301 in accordance with the sound emitted from the sound generator 301a. At this time, the sound generation device 301a emits a beep every 0.5 seconds in this example, and the operator holds the IC card 101 over the sound. For example, when the operator knows the authentication operation pattern 1001 in advance, the operation of holding the IC card 101 in time with a beep at the first 1 and not holding it at the beep at the next 0 is repeated.

  As a result, for the four beeps, the operation of holding, holding, holding and holding is performed. At this time, the IC card reader 301 sends data 1001 to the authentication apparatus 103 in response to holding, holding, holding, and holding. Inside the authentication device 103, the authentication unit 302 uses two data: data read from the IC card itself first sent from the IC card reader 301 and data 1001 created from an operation in accordance with a beep. And collate with the data of the authentication data storage device 103b. As a result, authentication can be performed using data read from the IC card itself and data obtained by subsequent operator operations.

  The operation of the IC card reader 301 in this series of operations will be described with reference to FIG. FIG. 3 is a flowchart for explaining the operation of the IC card reader 301. 201 is an initial state and is waiting for the IC card to be held. When the IC card is held over, the read data is transmitted to the authentication device 103 at 202. Further, it waits for the IC card to be released at 203 and proceeds to 204. In 204, the process of sounding a beep as an introduction sound and waiting for another 0.5 second is repeated a predetermined number of times. In this example, the introduction sound is defined as 4 times, and the operator performs an operation of holding or holding the sound a specified number of times following the beeping sound. 205 initializes a counter n for counting the prescribed number of repetitions to 1.

  Next, at 206, a beep is sounded, and at 207, it is determined whether or not the IC card is held over at the time of sounding. If not, 208 stores nth data as 0. If it is held over, it is determined at 209 whether or not it is the same as the IC card held over at the time of 201 first. If they are different from each other, it is determined that the authentication procedure is not normal, the subsequent authentication processing is stopped, and the process returns to 201 after waiting for the IC card to be released at 215.

  If it is determined at 209 that they are the same IC card, the nth data is stored as 1 at 210. After the nth data is stored in 208 or 210, it is determined in 211 whether or not it has been repeated a predetermined number of times. If not reached, 1 is added to the counter n at 212, and a prescribed time is awaited at 213. In this example, it is 0.5 seconds. Thereafter, the process returns to 206. If it is determined in 211 that the specified number of times has been reached, the first to nth data are transmitted as one data to the authentication device 103 in 214. In step 215, the process returns to 201 after waiting for the IC card to be released.

  Through the above processing, the operation of holding or not holding the operator can be used as the authentication data, and it is authenticated by the data by the operation of the operator in addition to the information of the IC card itself without providing the 10-key device. Will be able to.

  Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 4 is a block diagram showing a second embodiment of the present invention. The same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals. In FIG. 4, reference numeral 311 denotes an IC card reader according to the present invention. In this embodiment, a light emitting device 311a is provided instead of the sound producing device 301a of the first embodiment. The operation will be described with reference to FIG. FIG. 5 is a flowchart for explaining the operation of the IC card reader 311. The same parts as those in FIG. Processes 201 to 203 are the same as those in the first embodiment.

  In this embodiment, at 224, the process of emitting light from the light emitting device 311a as introduction light for a short time and waiting for 0.5 second is repeated a predetermined number of times. In this example, the introduction light is defined as four times, and the operator performs an operation of holding or not holding the light a specified number of times following the light emitted four times. In 226, light is emitted only for a short time. Other processes are the same as those in the first embodiment. Even in the case of the present embodiment, the operation of holding or not holding the operator can be used as the authentication data. In addition to the information on the IC card itself, data by the operation of the operator can be used without providing a 10-key device. You will be able to authenticate with. In addition, since the operation timing is clearly indicated by light rather than sound, it is characterized by being able to be operated even by an operator with hearing impairment.

  In the above embodiment, sound or light is used alone as means for clearly indicating the timing of holding the IC card, but the same effect can be obtained even when used together. In addition to sound and light, vibration such as a vibrator can be used. In short, the same effect can be obtained if there is a means for telling the operator when the IC card reader detects the IC card.
