Description

  The present invention relates to a seal verification device, a seal verification method, and a program.

  In general, when performing a transaction, a financial institution performs identity verification by checking a seal stamped on a form using a branch office terminal. The general seal verification flow is as follows.

  First, as a first step, the branch office terminal acquires a form image by scanning the form with a scanner connected to the branch office terminal. Next, as a second step, the branch terminal acquires the corresponding seal image from the seal server storing the customer's seal image using the account number / subject as a key. Next, as a third step, the branch office terminal cuts out the stamp area from the form image acquired in the first step, and acquires a seal impression. And as a 4th step, a branch office terminal collates the seal stamp acquired at the 3rd step, and the seal stamp image acquired at the 2nd step.

  For example, in Patent Document 1, in the third step, a position (a stamping field or a stamping area) where a stamp is cut out is specified for each type of form. Further, for example, in Patent Document 2, when a seal is stamped in an area other than the stamp area of the form, the operator can reset the position where the stamp is cut out.

  The image reading unit 112 and the seal data acquisition unit 126 illustrated in FIG. 1 correspond to the CPU 12 and the communication device 34, for example. The form identifying unit 114, the seal impression searching unit 118, the seal stamp extracting unit 120, the seal candidate position determining unit 124, and the seal collating unit 128 correspond to the CPU 12, for example. The form information DB 116 corresponds to the CPU 12 and the storage device 30, for example. The imprint candidate management unit 122 corresponds to, for example, the CPU 12 and the RAM 16.

  Next, a first seal collation process executed by the seal collation system 10 in FIG. 1 will be described. FIG. 3 is a flowchart of a first seal collation process executed by the seal collation system 10 in FIG. Note that processing not related to the seal collation executed by the branch terminal 110, for example, deposit / withdrawal processing is not related to the present invention, and thus description thereof is omitted.

  In FIG. 3, first, in the branch office terminal 110, for example, when an “image scan” key (not shown) is pressed, the scanner 130 acquires a form image from a form placed at a predetermined position on the scanner 130. To do. Then, the image reading unit 112 of the branch office terminal 110 acquires the form image acquired by the scan 130 (step S102).

  At this time, it is assumed that the form image is in a state where the form part is cut out based on the side of the form. This is possible by detecting the form side in the image based on the difference between the background brightness of the scanner image and the brightness of the form part. At this time, when the inclination of the form side is corrected by image rotation, an upright form image can be obtained. Alternatively, the same processing can be performed without cutting out the form part by specifying the coordinates of the form side in the acquired scanner image and using any vertex as a reference point.

  Next, the form identifying unit 114 of the sales office terminal 110 specifies the type of form from the form image acquired by the image reading unit 112 and also displays “store number”, “subject”, “account number”, and the like described in the form. Optical character recognition (OCR) is performed (step S104).

  Next, the seal data acquisition unit 126 of the branch office terminal 110 uses the “store number”, “subject”, and “account number” recognized by the form identification unit 114 in step S104 as keys, and the corresponding seal stamp from the seal server 210. The image is searched (step S106).

  Next, the seal stamp server 210 transmits the seal stamp image searched by the seal stamp data acquisition unit 126 in step S106 to the branch terminal 110 (step S108).

  Next, the seal stamp data acquisition unit 126 of the branch office terminal 110 acquires the seal stamp image transmitted from the seal stamp server 210 in step S108 (step S110).

  Next, the form identification unit 114 of the branch office terminal 110 uses the form type specified in step S104 and the “subject” recognized as a key as information from the form information DB 116, for example, the stamp area coordinates ( Xa, Ya) and (Xb, Yb) are acquired (step S112). Here, the stamp area is a place where a seal is supposed to be stamped in a form, that is, a stamp field. Further, as shown in FIG. 5, the stamp area coordinates are coordinates (Xa, Ya) and coordinates (Xb, Xb) of the upper left corner and the lower right corner of the form image based on one point in the form image, for example, the upper left corner. ).

  Next, the seal impression search unit 118 of the branch office terminal 110 searches the seal image candidate used for the seal stamp verification by the seal stamp verification unit 128 (hereinafter referred to as “imprint candidate”) from the entire form image acquired by the image reading unit 112. Then, the coordinates (Xlm, Ylm) and (Xmn, Ymn) of the searched seal candidate area are acquired (step S114). Here, the imprint candidate region is a region in which a circular imprint candidate is surrounded by a rectangle. In addition, as shown in FIG. 6, the imprint candidate area coordinates are one point in the form image, for example, the upper left corner coordinates (Xln, Yln) and the lower right corner coordinates (Xmn) based on the upper left corner. , Ymn). In step S114, the imprint candidate region coordinates are acquired for all the imprint candidates. N in the coordinates of the imprint candidate area is a mark for specifying the searched imprint candidate. For example, the coordinates of the first stamp candidate searched for are (Xl1, Yl1) and (Xm1, Ym1), and the coordinates of the next stamp candidate searched for are (Xl2, Yl2) and (Xm2, Ym2). . Here, the coordinates of the rectangle surrounding the imprint may be determined so as to circumscribe the imprint, or the outside may be surrounded by a predetermined amount from the imprint in consideration of chipping and the like.

  Next, the imprint cutting unit 120 of the branch office terminal 110 cuts out all the imprint candidate images from the form image based on the imprint candidate area coordinates acquired by the imprint search unit 118, and the imprint candidate management unit 122 selects the imprint candidate management unit 122. The images of all seal impression candidates cut out by the cutout unit 120 are stored (step S116).

  Next, the imprint candidate management unit 122 of the branch office terminal 110 determines whether there is an unprocessed imprint candidate (step S118).

図７は、上記方式１を満たした場合の帳票イメージにおける押印欄の拡大図である。 As a result of the determination in step S118, if there is an unprocessed imprint candidate (in step S118), the imprint candidate position determination unit 124 of the branch office terminal 110 determines whether or not the imprint candidate area is in the stamp area. Using the stamp candidate area coordinates and the stamp area coordinates, determination is made by the following method 1 (step S120).
[Method 1]

FIG. 7 is an enlarged view of the stamp column in the form image when the method 1 is satisfied.

  As a result of the determination in step S120, when the seal impression candidate area is in the seal area (in the seal area in step S120), the seal candidate position determination unit 124 of the branch office terminal 110 assigns the priority “1” to the seal stamp candidate. Set (step S122). Then, the process returns to the process of step S118 in order to shift the process to the next imprint candidate.

図８は、上記方式２を満たした場合の帳票イメージの拡大図である。 As a result of the determination in step S120, when the seal candidate area is not within the seal area (outside the seal area in step S120), the seal candidate position determination unit 124 of the branch office terminal 110 determines the seal candidate area and the seal area of the seal candidate. Is calculated by the following method 2 (step S124). Then, the process returns to the process of step S118 in order to shift the process to the next imprint candidate.
[Method 2]

FIG. 8 is an enlarged view of a form image when the method 2 is satisfied.

  As a result of the determination in step S118, when there is no unprocessed imprint candidate, that is, when the method 1 or the method 2 is applied to all the imprint candidates (none in step S118), the imprint of the branch office terminal 110 is performed. The candidate position determination unit 124 sorts the imprint candidates so that the value of the distance Ln calculated in step S124 is in ascending order with respect to the imprint candidates to which the method 2 is applied (step S126). .

  Next, the imprint candidate position determination unit 124 of the branch office terminal 110 sets the priorities “2”, “3”, “4”,... In order for the sorted imprint candidate group (step S128). FIG. 9 is an explanatory diagram showing an example of seal candidate data when the process up to step S128 in the first seal collation process of FIG. 3 is completed. In the present embodiment, it is assumed that an imprint candidate with a lower priority value is a higher imprint candidate with a higher priority in the selection of the imprint candidate in the seal collation. As a result, the priority is started from “2” for the seal imprint that is determined to be outside the stamp area.

  Next, the seal candidate management unit 122 of the branch office terminal 110 determines whether or not there is a seal stamp candidate that has not yet been subjected to seal verification by checking the seal stamp candidate data (step S130). In the seal stamp candidate data, “0” is set to “matched” for seal stamp candidates that have not been stamp verified (seal verification not completed). In addition, “−” is set as the distance for the seal impression candidate determined to be in the stamp area.

  As a result of the determination in step S130, when there is an imprint candidate that has not yet been verified (step S130), the imprint candidate management unit 122 of the branch terminal 110 selects the imprint candidate with the highest priority (step S132). . In the imprint candidate data of FIG. 9, the priority of the imprint 2 is set to the highest.

  Next, the seal collation unit 128 of the sales office terminal 110 performs seal collation using the seal image acquired in step S110 and the image of the seal impression candidate selected in step S132 (step S134). Then, the seal stamp collating unit 128 sets the collated flag of the seal impression candidate used for the seal stamp collation to “1”. FIG. 10 is an explanatory diagram illustrating an example of seal imprint candidate data after performing seal stamp collation on the seal imprint 2.

  Next, the seal collation unit 128 of the branch office terminal 110 determines whether the seal collation is OK or NG (step S136).

  If the result of determination in step S136 is that the seal collation is OK (OK in step S136), this process ends.

  As a result of the determination in step S136, when the seal verification is NG (NG in step S136), the process returns to step S130.

  As a result of the determination in step S130, when there is no seal imprint candidate that has not been subjected to seal verification (no step S130), the branch office terminal 110 determines that the seal imprint candidate could not be acquired, and manually operates the operator, for example. To set the seal impression candidate area (step S138). At this time, the operator visually confirms the imprint position from the form image and manually sets the imprint candidate area by operating the mouse.

  Next, the imprint cutting unit 120 of the branch terminal 110 cuts out the imprint candidate area set by the operator from the form image (step S140), and proceeds to the process of step S134. In the process of step S134, seal verification is performed using the seal stamp image acquired in step S110 and the image cut out in step S140. If the stamp verification is NG, processing such as canceling the transaction is performed according to the rules of the financial institution.

  According to the first stamp verification process of FIG. 3, it is possible to perform seal verification on a form in which a seal is stamped outside the stamp field without an operator's operation. In addition, since it is possible to perform seal verification for all seals in order from the seal closest to the seal field, even if a customer presses multiple seals on a form without knowing which seal is correct Verification can be performed. Usually, if there are multiple seals other than the stamp area, that is, if multiple seals are imprinted on the form, the seal imprint closer to the seal area is likely to be a regular seal, so the seal used for seal verification depends on the stamp area. Close ones are preferred.

  As described above, according to the first seal collation process of FIG. 3, when the seal is stamped in an area other than the stamp area of the form or when there are a plurality of seals on the form, the seal collation is efficiently performed. It can be carried out.

  In the first seal stamp verification process of FIG. 3, when the imprint candidate area is not in the stamp area, the distance between the imprint candidate area and the stamp area is calculated. The priority of the seal impression candidate may be set as described above by calculating the distances between the seal stamp candidate areas and the seal stamp areas of all the seal impression candidates without determining whether or not they are within. In this case, if the calculated distance is smaller than a certain value (for example, the distance from the center coordinates of the stamped area to the vertex of the rectangle of the stamped area or the side of the rectangle of the stamped area, etc.) You may make it discriminate | determine that it exists in an area | region.

  Next, a second seal collation process executed by the seal collation system 10 in FIG. 1 will be described. FIG. 4 is a flowchart of the second seal collation process executed by the seal collation system 10 in FIG. The second seal verification process is a modification of the process from step S130 to before step S134 in the first seal verification process described above. Since the processes other than the changed process are the same as the above-described first seal collation process, the description thereof is omitted.

  In FIG. 4, when there is an imprint candidate that has not yet been verified (step S 130) as a result of the determination in step S 130, the imprint candidate management unit 122 of the branch office terminal 110 displays an imprint candidate with a priority “1”. It is determined whether or not there is (step S142).

  As a result of the determination in step S142, when there is an imprint candidate with a priority “1” (“1” in step S142), the imprint candidate management unit 122 of the branch terminal 110 has the imprint with a priority “1”. A candidate is selected (step S144), and the process proceeds to step S134 described above. “1” as the priority is an example of a specific priority of the present invention.

  If the result of determination in step S142 is that there is no imprint candidate with a priority of “1” (“other” in step S142), the process proceeds to step S138 described above, and for example, the operator sets the imprint candidate region manually. Alternatively, the processing may be terminated by performing processing such as canceling the transaction according to the rules of the financial institution.

  According to the second seal verification process of FIG. 4, only the seal candidate with the priority “1” is determined to be a regular seal, and seal verification is performed for seals other than the seal column that the customer has imprinted by mistake. Since it is not implemented, financial transactions can be conducted safely.

  As described above, according to the second seal collation process of FIG. 4, when the seal is stamped in an area other than the stamp area of the form or when the form has a plurality of imprints, the seal is efficiently and safely performed. Verification can be performed.
