Computer readadle medium recording handwritten signature authentication program, and handwritten signature authentication method and apparatus

A computer readable medium storing a handwritten signature authentication program which when executed controls a computer to perform a process to authenticate an input handwritten signature by making a check between a predetermined component characteristic amount obtained by analyzing a characteristic of each component of data of the input handwritten signature, and a predetermined component characteristic amount obtained by analyzing a characteristic of each component of pre registered signature data, said process comprising:

• storing fonts of predetermined types and codes respectively corresponding to the fonts, as a handwriting dictionary in a handwriting dictionary storing unit;
• making a comparison and a reference between the fonts stored in the handwriting dictionary storing unit and handwriting shape data of an input handwritten signature, and reading codes corresponding to a closest font from the handwriting dictionary storing unit;
• generating a user ID by making a predetermined number of digits of numeric values of the codes are made successive in an order where the codes are read from the handwriting dictionary storing unit;
• making correspondence between the user ID and data of the input handwritten signature, and storing the user ID and the data of the input handwritten signature as registered signature data, when a signature is registered;
• reading previously stored registered signature data corresponding to user IDs generated by a user ID generating module from a registered signature data storing module when a signature is authenticated;
• and
• performing authentication based on the data of the input handwritten signature and the registered signature data.
