INDIVIDUAL BODY IDENTIFYING METHOD BY TWO-DIMENSIONAL CODE, HYBRID INDIVIDUAL PERSON AUTHENTICATING SYSTEM, AND OFF-LINE PERSON IDENTIFYING SYSTEM

摘要

An individual identifying method by encrypted two-dimensional codes, a hybrid individual person authenticating system, and an off-line person identifying system are disclosed. The content of two-dimensional codes representing encrypted individual body information is recorded as image information. Individual person specific information as an individual person recognizing means is composed of encrypted two-dimensional codes. The "order of arrangement" of two-dimensional codes mixed in dummies is made off-line input independent of card read information and online input information. Singular data created by subjecting image data on, e.g., a signature to a digital processing is added to data created by encrypting the individual person specific information as an individual person authenticating means. The resultant data is transformed into two-dimensional codes, which is printed on a document such as a certificate. In such a way, when individual person specific information such as a certificate is reproduced, image data such as on a signature is detected and reproduced based on the singular data, and thereby the person can be identified without online checking.
