Abstract

The invention provides an image file using and verifying method, compressing image file into a file packet to be stored at client end, and the file packet includes a list of HASH values of all files in the image file; when verifying the image file, reading in the list of HASH values; drawing a record from the list; calculating the HASH value of an image file in the client end corresponding to the record; comparing whether the HASH value of the record is equal to the calculated HASH value of the current file. Thus, it can prevent image files being modified at will.

Description

technical field [0001] The invention relates to image data processing technology, in particular to a method for verifying and using image files to prevent the image files from being changed arbitrarily.
