摘要

A multimedia recording system verifies whether or not multimedia data created from an object belongs to the intended object, and has a multimedia recording apparatus which acquires object-specifying information specifying the object, creates first digest data from the multimedia data and creates authentication data by encrypting the first digest data with the object-specifying information, and records the authentication data, a server apparatus which decrypts the authentication data by using the object-specifying information previously registered on the server apparatus to create second digest data, compares the second digest data with the first digest data of the multimedia recording apparatus, and outputs a result of comparison of the first digest data and the second digest data as comparison data, and a verification apparatus which displays a result of verification of whether or not the multimedia data created from the object belongs to the intended object based on the comparison data sent from the server apparatus.
