【発明の詳細な説明】
（産業上の利用分野）
本発明はシステムのアクセス権の判定装置に関し、特に
第三者のアクセス（不正アクセス）を防止するアクセス
権の判定装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an access right determination device for a system, and more particularly to an access right determination device for preventing third party access (unauthorized access).
（従来の技術）
従来、システムに対するアクセス権の判定は、キーボー

ときに不当なアクセス権を有するものと判断していた。(Prior Art) Conventionally, access rights to a system have been determined by determining whether a password or PIN entered using a keyboard or magnetic card matches a password or PIN previously registered in the system (control device). If they match, it is determined that the access rights are illegal.

いという欠点がある。(Problem to be Solved by the Invention) Confirmation control of access rights for the conventional system described above uses a password or pin number registered in advance in the system, and a password or pin code input by a person attempting to access the system. Since it was a method of comparing with
This method has the drawback that it is not possible to know whether the accesser is an illegitimate holder, and it is also impossible to keep track of access history for specific users.

。(Means for Solving the Problems) An access right determination device according to the present invention inputs a fingerprint,
a fingerprint input means for temporarily storing a fingerprint image; a verification data extraction means for extracting verification data from the fingerprint image; a password input means for inputting a password; a verification means for verifying the identity of the user; a verification fingerprint data reading means for selectively reading out a set of fingerprint data to be verified using a password determined to be valid by the verification means; and verification data extracted by the verification data extraction means. and verification means for verifying the fingerprint data selectively read out by the verification fingerprint data reading means; and determination means for determining access rights based on the verification means and the output of the verification means. There is.
（実施例） 次に、本発明について図面を参照して説明する。(Example) Next, the present invention will be explained with reference to the drawings.
第１図は本発明によるアクセス権の判定装置の一実施例
を示すブロック図である。FIG. 1 is a block diagram showing an embodiment of an access right determination device according to the present invention.

きデータの集合を読出す、照合データ読出し指示信号３
２は入力された暗証番号により変化し、照合データ格納
部５から読出すデータを選択する。A person who wishes to have access rights determined (a person accessing the system) inputs his or her personal identification number into the device 1 through the identification number input section 2 and inputs his or her fingerprint through the fingerprint input section 6, respectively. The validity of the input FJIi identification number is confirmed by the PIN verification section 3, and if it is invalid, it outputs an invalidation instruction signal 31, and if it is valid, it outputs a verification data readout instruction signal 32. When the verification data readout section 4 receives the readout instruction signal 32, the verification data readout instruction signal 3 reads out a set of data to be verified from the verification data storage section 5.
2 changes depending on the input password and selects data to be read from the verification data storage section 5.
一方、入力された指紋イメージは入力指紋イメージ格納
部７に一時的に格納され、照合データ抽出部８において
特徴点等の照合データか抽出される。On the other hand, the input fingerprint image is temporarily stored in the input fingerprint image storage section 7, and a verification data extraction section 8 extracts verification data such as minutiae.
抽出された照合データと、照合データ読出し部４により
読出されたデータの集合とは指紋照合部９で照合され、
照合結果信号９１が出力される。The extracted verification data and the set of data read out by the verification data reading unit 4 are verified by the fingerprint verification unit 9,
A verification result signal 91 is output.

スの履歴が収集できることになる。The access right determination unit 10 determines whether the person who has attempted to have access rights determined is a legitimate right holder based on the verification result signal 91 and the password invalidation instruction signal 31. Therefore, even if a third party has access rights determined, the probability that both the password and the input fingerprint will match is extremely low, so unauthorized access can be prevented. Additionally, the history of accesses to specific persons can be collected.

クセスの履歴の収集が可能となるという効果がある。(Effects of the Invention) As explained above, the present invention determines access rights based on a PIN number and fingerprint information, which not only prevents unauthorized access by a third party, but also prevents access history for a specific person. This has the effect of making it possible to collect.
