Abstract
A device for integrity verification of image data. The device comprises: a database configured to store multiple field signatures respectively corresponding to multiple editing tools; a memory configured to store a program for integrity verification of image data; and a processor configured to execute the program stored in the memory. The processor: extracts a field from the image data when the program is executed; determines whether or not there is a field signature matched with the extracted field from among the multiple field signatures; and determines whether or not the image data are edited depending on a result of the determination.
