1. An image verification system for verifying a correspondence between a current sample image, and a reference image registered beforehand, comprising:
- means for storing a relationship between a characteristic of a known sample image and characteristics of said reference image when said known sample image is known to correspond to said reference image; and
means for determining if said current sample image corresponds to said reference image by determining said relationship between said characteristic of said current sample image and said characteristics of said reference image and determining if said relationship corresponds to that stored, wherein said relationship stored in said storing means is formed by classifying said relationship into plural clusters of standard data within which correlation between images is acceptable, said determining means verifies said current sample image as corresponding to said reference image if it is within one of said clusters, and wherein said characteristics include all of a blur ratio indicative of smearing of ink made during a sealing process, a faint and scratchy ratio and an identification ratio.

Abstract
An image verification system for verifying whether a sample image corresponds to a reference image registered beforehand. A relationship between the sample and the reference image is stored when the sample image corresponds to the reference image. The sample image is compared with the reference image by verifying the sample and the reference according to the relationship between characteristics values of the sample and reference.
