Photographed subject authentication system
First Claim
1. A photographed subject authentication system which performs photographed subject authentication using a photographed subject authentication card, comprising:
- a storing device for storing original image data obtained from a photographed subject and compression condition for compressing the original image data to obtain first compressed image data;
a first compression device for compressing the original image data based on the compression condition;
a compressed image data writing device for writing the first compressed image data and related information corresponding to the photographed subject into the photographed object authentication card;
a compressed image data reading device for reading a third compressed image data from the photographed subject authentication card;
a related information obtaining device for obtaining related information corresponding to the photographed subject from the photographed subject authentication card;
a data specifying device for specifying the original image data corresponding to the first compressed image data and the compression condition read from the storing device based on the obtained related information;
a second compression device for compressing the specified original image data based on the specified compression condition to obtain second compressed image data; and
a data verifying device for comparing the third compressed image data with the second compressed image data to determine whether the third compressed image data is equal to the second compressed image data, wherein the data verifying device determines that the third compressed image data is equal to the first compressed image data when the result of the comparison is that the third compressed image data is equal to the second compressed image data.

Abstract
A photographed subject authentication system comprising: a compressed image data writing device for writing the first compressed image data and related information into the photographed object authentication card; a compressed image data reading device for reading a third compressed image data from the photographed subject authentication card; a data specifying device for specifying the original image data corresponding to the first compressed image data and the compression condition read based on the obtained related information; and a second compression device for compressing the specified original image data based on the specified compression condition to obtain second compressed image data, wherein the data verifying device determines that the third compressed image data is equal to the first compressed image data when the result of the comparison is that the third compressed image data is equal to the second compressed image data.

8. A photographed subject authentication system which performs photographed subject authentication using a photographed subject authentication card, comprising:
-
a storing device for storing original image data obtained from a photographed subject and compression condition for compressing the original image data;
a compressed image data reading device for reading a third compressed image data from the photographed subject authentication card;
a related information obtaining device for obtaining related information corresponding to the photographed subject from the photographed subject authentication card;
a data specifying device for specifying the original image data and the compression condition read from the storing device based on the obtained related information; and
a data verifying device for comparing the third compressed image data with the compressed-original image data compressed based on the specified compression condition to determine whether the third compressed image data is equal to the compressed-original image data, wherein the data verifying device determines that the third compressed image data is valid when the result of the comparison is that the third compressed image data is equal to the compressed-original image data.
