Description

  The present invention relates to a personal verification system that performs personal verification using a fingerprint and a method for controlling the personal verification system.

  Conventionally, personal verification systems that perform personal verification based on fingerprints are less likely to be lost or forgotten by individuals and prevent fraud due to counterfeiting than personal verification systems based on cards or passwords. Since it has the feature of being easy to do, it is widely used in various fields.

  These personal verification systems read a fingerprint as an optical image or a pressure distribution image from a fingertip placed at a predetermined position of the fingerprint input unit, and extract feature points of a plurality of fingerprints from the read fingerprint image, Get fingerprint information. This fingerprint information is collated with the fingerprint information registered in advance. When the fingerprint information matches, the corresponding individual is specified by the fingerprint information registered in advance, and the collation is completed.

  However, the fingerprint image read by the fingerprint input unit is not always a clear image over the entire required image range. Accordingly, the fingerprint information obtained from such a fingerprint image does not necessarily match all the feature points of the fingerprint information registered in advance with the predetermined feature points. Therefore, a criterion for determining whether or not the fingerprint information matches or not is set in advance depending on how many feature points match, and a collation result is output depending on whether or not this criterion is satisfied.

  This means that if the criteria are tightened, the acceptance rate of others, which means the error of accepting another person as the principal, will decrease, but the false rejection rate, which is an error that the principal is not the principal, will increase, and if the criteria are relaxed, This means that the acceptance rate for others is high and the rejection rate is low.

  This can be said to be a conflicting condition that if the safety is increased, the convenience is lowered, and if the safety is increased, the safety is lowered.

  To deal with such problems, register fingerprints of multiple fingers in the order unique to each individual, collate the input fingerprints in the registered order, and match both the fingerprint and the input order In this case, there is a proposal of an apparatus in which an individual succeeds in collation (for example, see Patent Document 1).

However, it is conceivable that the input order is forgotten or that the input order is incorrect at the time of input, and it cannot be said that both safety and convenience are satisfied.

  FIG. 1 is a conceptual diagram of a personal verification system.

  The personal verification system includes an information processing device 1, a fingerprint verification device 2, and a connection cable 3.

  The information processing apparatus 1 is typically a personal computer, but may be an apparatus having a function connectable to a fingerprint collation apparatus, for example, an image forming apparatus such as a copier, a fax machine, or a printer. In this example, a personal computer is applied.

  The fingerprint collation device 2 includes a fingerprint input unit 21, reads a fingerprint of a finger placed at a predetermined position, obtains a fingerprint image, extracts fingerprint feature points and the number thereof from the fingerprint image, and prints fingerprint information. Is generated. The generated fingerprint information is collated with previously registered fingerprint information, and when collation is successful, an individual having the fingerprint is specified.

  The connection cable 3 is a communication cable having connectors at both ends, and a cable that conforms to a predetermined specification such as USB or RS232C is adopted. In this embodiment, communication between apparatuses is performed using a communication cable, but communication may be performed wirelessly. Moreover, you may incorporate in one apparatus, without using a cable.

  FIG. 2 is a block diagram showing the control relationship of the personal verification system.

  The control unit C1 of the information processing apparatus 1 is a computer system including a CPU (CPU1), a memory M1, and an arithmetic unit, an I / O port, a communication interface, etc. (not shown), and a predetermined interface. Are connected to the input unit 11 and the display unit 12, which are user interface devices, and the control unit C 2 of the fingerprint collation device 2.

  Each control is performed by executing a program corresponding to the job, which is software stored in the memory M1.

  The control unit C2 of the fingerprint collation device 2 is a computer system including a CPU (CPU2), a memory M2, and an arithmetic unit, an I / O port, a communication interface, etc. (not shown in the figure). The collation process is performed based on the fingerprint information obtained by processing the fingerprint image input from 21, and the collation result is sent to the connected information processing apparatus 1.

  Each control is performed by executing a program corresponding to the job, which is software stored in the memory M2.

  In the figure, the description of blocks not directly related to the description of the embodiment of the present invention is omitted.

  Next, verification processing by the personal verification system will be described.

  Prior to the operation of the system, the personal verification system needs to register personal fingerprint information to be personally verified beforehand.

  FIG. 3 is a flowchart showing the flow of fingerprint information registration.

  When the execution of fingerprint information registration 101 which is a program stored in the memory M1 is started by an instruction operation from the input unit 11 of the information processing apparatus 1 (step S1), the display unit 12 of the information processing apparatus 1 displays a fingerprint. Entering the personal name or personal code to be registered, and placing a finger designated by the fingerprint input unit 21 of the fingerprint collation device 2, such as the index finger of the right hand, or a plurality of fingers in a predetermined order at predetermined positions. A prompting display is output (step S2).

  When the personal name is input by the input unit 11 and the fingerprint is input by the fingerprint input unit 21 (step S3: Y), the feature point extraction 201 which is a program stored in the memory M2 of the fingerprint collation device 2 is performed. Is called and executed, and the input fingerprint is read as an image. Then, the feature points of the fingerprint are extracted and encoded to generate fingerprint information (step S4).

  The generated fingerprint information is combined with the personal name sent from the information processing apparatus 1 and stored in the registered fingerprint information file 202 which is a data file provided in the memory M2 for sequentially storing the combined data. Registration of fingerprint information for the minute is completed (step S5).

  When the registration is completed, registration completion information is sent from the control unit C2 of the fingerprint collation device 2 to the control unit C1 of the information processing device 1, and the display means 11 of the information processing device 1 displays the next personal name and fingerprint image. A display prompting input is output (step S6). If it is necessary to perform the next registration (step S7: N), the processing of steps 3 to 6 is repeated. If the next registration is not necessary (step S7: Y), the fingerprint information registration routine is started. Get out.

  In this example, the input unit 11 of the information processing apparatus 1 performs display for prompting the input of the personal name and the display unit 12 of the information processing apparatus 1 to input the personal name and the fingerprint image. 2, an input unit, a display unit, and a fingerprint information registration file may be provided so that fingerprint information can be registered by a single fingerprint verification device.

  Next, the flow of personal verification by the personal verification system that has completed personal fingerprint registration will be described.

  FIG. 4 is a flowchart showing the flow of personal verification in the first embodiment.

  When an instruction input for executing a program for personal verification is made from the input unit 11 of the information processing apparatus 1, instruction information is sent from the control means C1 to the control means C2, and the mode transition between the two modes has been performed. The mode transition flag 203 that stores whether or not is reset (step S10). Next, an image for selecting one of the two modes is displayed on the display unit 12 (step S11).

  If mode 1 is selected (step S12: Y), selection information indicating that mode 1 has been selected is sent from the control unit C1 of the information processing device 1 to the control unit C2 of the fingerprint collation device 2. Then, various settings for processing in mode 1 are made in the fingerprint collation apparatus 2 by the mode setting program 204 (step S13). Next, an image instructing the fingerprint input from the fingerprint input unit 21 of the fingerprint collation apparatus 2 is displayed on the display unit 12 of the information processing apparatus 1 (step S14).

  When a fingerprint is input (step S15: Y), after the feature points of the fingerprint are extracted from the fingerprint image by the first algorithm and the fingerprint information is generated, the fingerprint information in the registered fingerprint information file 202 registered in advance is Are collated (step S16). The first algorithm here refers to extracting fingerprint feature information by extracting the positions and directions of a plurality of fingerprint feature points (end points and branch points of fingerprint ridges) and, in some cases, their interrelationships. A known technique for collating the generated fingerprint information with pre-registered fingerprint information can be used. The verification accuracy is generally evaluated based on the principal rejection rate and the other person acceptance rate, but as described above, these are usually contradictory numbers. For example, if the number of feature points to be extracted and the number of feature points that must be matched with each other are increased, the person rejection rate increases and the other person acceptance rate decreases. In the present embodiment, the first algorithm is set so that the rejection rate is higher and the acceptable rate is lower than that of the second algorithm.

  When the collation result that the fingerprint information is registered in the registered fingerprint information file 202 is obtained, that is, when the collation is successful (step S17: Y), collation is performed from the control unit C2 to the control unit C1. The personal name corresponding to the fingerprint information that has been successfully sent is sent (step S18).

  On the other hand, when collation fails, that is, when a collation result is obtained that the fingerprint information is not registered in the registered fingerprint information file 202 (step S17: N), the collation control unit which is software 240 determines whether or not the mode transition flag 203 is set (step S19). If it is not set (step S19: N), the mode transition flag 203 is set (step S20). The process proceeds to fingerprint collation in mode 2 (step S21), and if it is set (step S19: Y), information notifying that collation has failed is sent from the control means C2 to the control means C1 (step S31).

  When mode 2 is selected in step 12 (step S12: N), or when processing has flowed from step 20, various settings for performing processing in mode 2 are set by the mode setting program 204 in the fingerprint collation device. (Step S21). Next, an image instructing a plurality of fingerprint inputs from the fingerprint input unit 21 of the fingerprint collation device 2 is displayed on the display unit 12 of the information processing apparatus 1 (step S22).

  When a predetermined number of fingerprints are input (steps S23 and S24), after the fingerprint information of the number of fingerprints input by the second algorithm is generated, these fingerprint information is sequentially registered in advance as registered fingerprint information. The fingerprint information in the file 202 is collated (steps S25 and S26). When all the fingerprint information has been successfully verified (step S27: Y), the personal name corresponding to the fingerprint information that has been successfully verified is sent from the control means C2 to the control means C1 (step S18).

  If the collation fails, that is, if any one of the plurality of fingerprint information fails, 1 is added to the value K of the collation counter 205 that counts the number of collations performed in mode 2. (Step S28). The value K of the collation counter 204 is set to zero prior to the mode 2 collation process by the mode 2 setting in step S21.

  The value K of the collation counter 205 is compared with a preset value KK (step S29). If K <NN (step S29: N), an image prompting the collation again in mode 2 is displayed on the display unit. 12 (step S22), and the processing of steps 23 to 27 is repeated. If fingerprint verification is not successful even after repeated fingerprint input (step S27: N), steps 22 to 27 are repeated until the value K of the verification counter 204 reaches KK.

  If collation is successful before K reaches KK (step S27), the personal name corresponding to the successful fingerprint information is sent from the control means C2 to the control means C1 (step S18), but K is KK. If the collation is not successful even after reaching (steps S27: N to S29: Y), the collation control unit 240 determines that the collation in mode 2 is unsuccessful, and refers to the mode transition flag 102. Thus, it is confirmed whether or not the mode 1 has been changed to the mode 2 (step S30). If the mode 1 has been changed to the mode 2 (step S30: Y), the control is performed from the control means C2. Information notifying that the verification has failed is sent to the means C1 (step S31).

  If the mode has not been shifted from mode 1 to mode 2 (step S30: N), the collation control unit 240 sets the mode transition flag 102 (step S32) and shifts to mode 1.

  As described above, a system that performs fingerprint collation using either one or both of two algorithms having different refusal rates and other-person acceptance rates can achieve collation rather than fingerprint collation using one algorithm. A system is realized in which the ratio of rejected persons is high and the rejection rate of others and the acceptance rate of others are not increased.

  FIG. 5 is a flowchart showing the second embodiment.

  Since the flowchart of the present embodiment has many parts that overlap with the flowchart of the first embodiment shown in FIG. 4, only the vicinity of different processing steps is described.

  In the first embodiment, in mode 2, a plurality of fingerprint information is obtained from a plurality of inputted fingerprints, and all the fingerprint information is collated with the fingerprint information registered in the registered fingerprint information file. Although it is assumed that the individual has been collated when all have been successfully collated (FIG. 4, steps S23 to S27), in this embodiment, the input order of each fingerprint information that has been successfully collated is determined ( In step S100), this order is checked against the input order registration file 210 in which the input order is registered in advance, and it is determined whether or not the input order is correct (step S101). That is, this is a process in which it is assumed that the collation of the individual is successful when all the inputted fingerprint information is successfully collated and the input order matches the pre-registered order.

  By such processing, personal verification with higher identification rejection rate is realized with higher verification accuracy than personal verification in mode 2 of the first embodiment using only fingerprint information.

  FIG. 6 is a flowchart showing the third embodiment.

  Since the flowchart of this embodiment also has many parts that overlap with the flowchart of the first embodiment shown in FIG. 4, only the vicinity of different processing steps is described.

  In the first embodiment, in mode 2, a plurality of fingerprint information is obtained from a plurality of inputted fingerprints, and all the fingerprint information is collated with the fingerprint information registered in the registered fingerprint information file. In this embodiment, the fingerprint is input a predetermined number of times, but is used for fingerprint verification. Only fingerprint information input in the input order corresponding to the numerical value M set in the collation fingerprint designation file 230 in advance is selected as a fingerprint collation target (step S200), and fingerprint collation is performed (step S200). S25).

  Note that one or more numerical values may be set in the collation fingerprint designation file 230.

  By such processing, the processing time required for fingerprint collation is shortened compared to the case of the first embodiment.

  FIG. 7 is a flowchart showing the fourth embodiment.

  In the third embodiment described above, a plurality of fingerprint inputs are accepted, and only the fingerprint input at a predetermined number of times is used as fingerprint information. At least one numerical value P is set in advance so that the Pth input fingerprint is not used as fingerprint information. Note that the numerical value P may be set and fixed in advance in the unused input count file, or may be changed for one or more individual verifications.

  Since the flowchart of this embodiment also has many parts that overlap with the flowchart of the first embodiment shown in FIG. 4, only the vicinity of different processing steps is described.

  When the first fingerprint is input in accordance with the fingerprint input instruction (steps S22 and S23), 1 is added to the content J of the fingerprint input number counter 260 (step S300).

  Next, it is determined whether or not J = P (step S300). If J = P, the input fingerprint is not used as fingerprint information for collation (step S300: Y). If J is not equal to P (step S300: N), it is determined whether or not J is greater than or equal to a predetermined fingerprint input count JJ (step S301), and if not greater than JJ (step S301: N). The inputted fingerprint is used as fingerprint information for collation (step S25), and if it is JJ or more (step S301: N), the process proceeds to determination of whether collation is successful (step S27). .

  As described above, in this embodiment, fingerprint input not used as fingerprint information is counted as the number of times of input, a predetermined number of fingerprint inputs are requested, and the number of times of input is set as one of the conditions for fingerprint verification. The fingerprint information used in the process is appropriately omitted to shorten the processing time.

  In the above-described embodiment, a personal computer is applied as the information processing apparatus. However, in the case where an image forming apparatus is applied instead of this, after personal verification is performed, the information is stored in association with the corresponding user. It is also possible to automatically set the print conditions, for example, the conditions such as the magnification, density, and post-processing. Further, after performing personal verification, control may be performed so as to execute confidential printing for the corresponding user.

  As described above, according to the present invention, there are provided a personal verification system having two algorithms for fingerprint verification and performing fingerprint verification utilizing the characteristics of each algorithm, and a verification method of the personal verification system.
