摘要： A recording medium for storing an electronic image data verification program, an electronic image data verification system, and an electronic image data verification method are provided to generate partial signature information separately from registered electronic image information, divide and maintain the partial signature information, and clearly separate functions/roles of the electronic image information(original information) and the partial signature information(verification information), thereby detecting presence or absence of changes to the registered electronic image information and specifying a changed portion(position of a change) and accordingly proving the presence or absence of the changes and the changed portion to the third party. In a computer-readable recording medium for storing an electronic image data verification program which makes a computer execute verification of electronic image information, the electronic image data verification program comprises the followings steps of: a partial signature information generation step which uses partial information of the electronic image information, in order to generate partial signature information for specifying presence or absence of a change to the electronic image information and a changed portion if a change has been made(3); a registration step which registers the electronic image information and the partial signature information generated from the electronic image information(2); and a verification step which uses the electronic image information and the partial signature information registered by the registration step, in order to verify presence or absence of the change to the electronic image information, or a changed portion if a change has been made to the electronic image information(4).
