An electronic file certification, validation or comparison method and system. The method includes the steps of: a) receiving a first file at a server from a first user; b) encoding with an electronic tattoo the first file with a first unique serial code to thereby certify the first file; c) encrypting and storing the first file in the server; d) receiving a second file at the server from a second user, the second file having a second unique serial code; and e) comparing the second unique serial code to the first unique serial code. If the serial codes mismatch an e-mail is sent to the second user indicating that the second file is not certified, or else decrypting the first file, and comparing the second file to the decrypted first file. If the files match an e-mail is sent to the second user indicating that the second file is a true copy of the first file, if not it indicates that the second file is not a true copy of the first file.
