TECHNICAL FIELD OF THE INVENTION
The present invention relates to a palmprint collation method and a palmprint collation method for identifying a person having a retained palmprint by comparing a left palmprint left at an incident site or the like with a palmprint stored in a database.
[0002]
[Prior art]
In the field of criminal investigations that have conventionally relied on fingerprint matching, the importance of matching with palm patterns (palm prints) has recently begun to be recognized.
[0003]
[Problems to be solved by the invention]
Since the palmprint matching method is computerized similarly to the fingerprint matching method, if the resident palmprint matches a part of the entire palmprint or a part of the side palmprint stored in the database, it is highly accurate. Although a person having a left palm print can be specified, when a left palm print extends over all palm prints and a side palm print, a person having a left palm print could not be specified with high accuracy.
[0004]
That is, referring to FIG. 3, since the remaining palm print is compared with a part of the entire palm print, even if a part of the entire palm print matches a part of the remaining palm print, other parts of the remaining palm print match what. Because it was unknown, it was not possible to identify the person holding the palm print. Similarly, referring to FIG. 4, since a part of the left palm print and a part of the side palm print are compared, even if a part of the side palm print matches a part of the left palm print, other parts of the left palm print match no matter what. It was not possible to identify the person holding the palm print, because it was unknown.
[0005]
An object of the present invention is to provide a palmprint collation method and a palmprint collation method capable of specifying a person having a retained palmprint with high accuracy even when the retained palmprint straddles the entire palmprint and the side palmprint. And

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0016]
FIG. 1 is a block diagram showing a configuration of a palm print collation method according to an embodiment of the present invention.
[0017]
Referring to FIG. 1, a palm print collation method according to the present embodiment includes a left palm print reading unit 101 for optically reading a left palm print, personal information such as the name and address of at least one person (usually, a large number of persons), and a seal of the person. The palm print database 102, which stores the entire palm print and the seal side palm print in association with each other, reads the seal full palm print from the palm print database 102, and compares the read seal full palm print with the retained palm print read by the retained palm print reading means 101. All-palm-print collation means 103, side-palm-print collation means 104 for reading the imprint-side palm-palm from the palm-print database 102 and collating the read imprint-side palm-palm with the residual palm-print read by the retained-palm-print reader 101; The palm print and the imprint side palm / palm print are read from the palm print database 102, and all or a part (normally a part) Combined palm print generating means 105 for combining all or a part (usually a part) of the imprint side palm / palm print to generate an imprint combined palm print; Receiving the collation results of the combined palmprint collation means 106, all palm / palmprint collation means 103, side palm / palmprint collation means 104, and coupled palmprint collation means 106, which are compared with the read palmprint, and processes them. Is provided.
[0018]
Next, a palm print matching method performed by the palm print matching method according to the embodiment of the present invention will be described with reference to FIG.
[0019]
The flowchart shown in FIG. 2 shows a process for one person whose personal information and the like are recorded in the palm print database. The processing shown in FIG. 2 is performed for some persons who satisfy the conditions.
[0020]
Referring to FIG. 2, first, the left palm print reading unit 101 optically reads the left palm print (S201). Next, the all palm / palm print collation unit 103 reads the imprint all palm / palm print from the palm print database 102 (S202). Next, the all-palm-print collation means 103 collates each part of the left palm-print and the imprinted all-palm print, and determines whether any part of the left palm-print and the imprint-all-palm print matches (S203). If the determination result in S203 is affirmative, the process proceeds to S210 (described later). If the determination result in S203 is negative, the palm / palm-print collation unit 104 reads the seal / palm-print from the palm-print database 102 (S204). Next, the palm / palm-print collation unit 104 compares each part of the left palm / palm-print with the stamp / palm-print, and determines whether any part of the left palm-print and the stamp / palm-print matches each other (S205). If the determination result in S205 is affirmative, the process proceeds to S210 (described later). If the determination result in S205 is negative, the combined palmprint generating means 105 reads the stamped palm / palmprint from the palmprint database 102 (S206), and reads the stamped palm / palmprint (S207).
[0021]
Next, the combined palm print generating means 105 combines the portion of the read stamped palm / palm print adjacent to the stamped palm / palm print with the portion of the stamped palm / palm print adjacent to the stamped / palm print to generate an imprinted combined palm print. (S208).
[0022]
In step S208, the combined palm print generating unit 105 combines all of the read stamp palm / palm prints and all of the stamp / palm palm prints to generate a combined stamp / palm print (S208). In this case, steps S201 to S205 become unnecessary.
[0023]
Next, the combined palm print collation unit 106 compares each part of the left combined palm print with the imprint combined palm print, and determines whether or not any part of the left combined palm print and the imprint combined palm print matches (S209). If the determination result in S209 is affirmative, the process proceeds to S210; otherwise, the collation between the imprint palm print of the subject and the remaining palm print is ended. In S210, the collation result processing means 107 searches the palm print database 102 for personal information of the person corresponding to the imprinted palm print that matches the resident palm print, and outputs the personal information as a collation result.
[0024]
Note that, in the above-described method illustrated in FIG. 2 performed by each unit illustrated in FIG. 1 of the palm print collation method, the computer reads a computer program for causing the computer to execute the method from a recording medium, or executes an ASP (Application Server). (Provider) or the like via a network such as the Internet and the like, and can be executed.
[0025]
【The invention's effect】
The effects of the present invention will be described with reference to FIGS.
[0026]
When the retained palm print straddles the entire palm print and the retained palm print, when each part of the stamped all palm print is compared with the retained palm print, as shown in FIG. Even if it does, since there is no part of the imprinted entire palmprint that matches the other part of the remaining palmprint, it is not possible to obtain an imprinted full palmprint completely matching the remaining palmprint, and it is possible to identify the person who has the remaining palmprint. Can not. Further, in such a case, when each part of the imprint-side palm print is collated with the retained palm print, as shown in FIG. 4, even if the effective portion of the collation portion matches a part of the retained palm print, Since there is no portion of the imprint side palm / palm pattern corresponding to the other part, the imprint side palm / palm pattern completely matching the surviving palm pattern cannot be obtained, and a person having the surviving palm pattern cannot be obtained.
[0027]
However, in such a case, when each part of the imprinted combined palm print is compared with the remaining palm print, as shown in FIG. 5, since the entire matching portion matches the entire remaining palm print, the person having the remaining palm print is identified. can do.
[0028]
Therefore, in the conventional example in which only the collation of the remaining palm print with the imprinted palm palm print and the collation of the retained palm print with the imprinted palm are conventionally performed, if the retained palm print is straddling the entire palm print and the retained palm print, Although the person having the palm print was not able to be specified, the present invention which also performs the comparison between the remaining palm print and the combined palm print, according to the present invention, even if the remaining palm print extends over the entire palm print and the remaining palm print, Therefore, for example, it is possible to increase the arrest rate of a criminal, thereby improving security.
