Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a seal verification method for determining the authenticity of a seal imprinted on a bill, a check, or the like.

[Prior art]

Traditionally, in banks, the impressions of seals used in transactions with customers are registered in three ledgers called the seal register, and the registered seals and the impressions stamped on checks, bills, and bankbooks are visually checked. Comparisons and cross-checks have been carried out, but it takes time to search for the desired registered seal imprint in the ledger.

Further, FIG. 1 shows an example in which the matching method is mechanized in order to shorten the search time. This device is equipped with a registered seal imprint file 1 that holds registered seal imprints that serve as a reference for comparison, and a number input keyboard 4 in which a number attached to each registered seal impression is read out from this file 1 as a registered seal imprint pattern that serves as a reference for comparison.
By inputting more information, 1. The corresponding registered seal imprint patterns are sequentially outputted from 1, processed into image patterns by the processing processor 3, and displayed as images on the image display device 5 (L). is optically read and converted into an electric @ sign, and the signal is input to the processing processor 3.Furthermore, this stamp pattern information is subjected to image pattern processing by the processing processor 3, and displayed as an image on the image display device 5. The image display device 5 displays a second seal imprint image read from the former registered seal imprint file 1 and a second seal imprint image read from the latter seal imprint reader 2.
As shown in the figure, they are displayed in parallel on the same screen. Authenticity is verified by visually comparing and verifying the two seal impressions A and A' displayed in parallel on the same screen. This method has the drawbacks of low verification reliability, such as the long time it takes to verify the entire seal imprint, the fact that it is easy to overlook differences, and the inability to determine differences in size even though the imprint patterns are the same.

[Purpose of the invention]

The object of the present invention is to provide a low-cost device that allows such seal imprint verification to be performed easily and reliably.

[Summary of the invention]

The present invention divides a reference seal imprint and a verified seal imprint into two with the same dividing line, constructs one seal imprint with opposite parts, and determines authenticity by verifying the joint.

[Embodiments of the invention]

FIG. 3 shows an embodiment of the present invention, in which numeral 6 denotes an image synthesis processor that divides and synthesizes two seal impression patterns, and numeral 7 denotes a keyboard that provides the image synthesis processor 6 with dividing boundaries of patterns. In response to designations from the number input keyboard 4, the registered seal imprint pattern read from the file 1 and the imprint pattern read by the seal imprint reader 2 are input to the image synthesis processor 6, respectively. As shown in FIG. 4, the image synthesis processor 6 receives a boundary line instruction (from the keyboard 7) for dividing a pattern for image synthesis, and divides both patterns into two at the specified boundary line.

Furthermore, the image synthesis processor 6 synthesizes one seal imprint pattern using the divided pieces of the registered seal imprint pattern and the divided pieces of the input seal imprint pattern on the opposite side. The image synthesis processor 6 inputs this synthesized seal impression pattern to the image processing processor 3. The image processing processor 3 processes this information into a display image and displays it as an image on the image display device ft5 as shown in FIG. By visually inspecting the degree of image joining on the composite boundary line of this composite seal imprint image, accurate authenticity determination can be made. Since it is insufficient to have only one composite boundary line, a plurality of them are required, but by using a boundary setting keyboard 7 as shown in FIG. 5, the operation can be made easier.

〔Effect of the invention〕

According to the present invention, the disadvantage of visual redundancy caused by alternate visual comparison of two patterns is eliminated, and since the objects of comparison are simultaneously visible, the comparison becomes absolute and the reliability of matching is improved.
