Abstract
A system includes an authentication server and a media authentication device. The authentication server stores authenticated media files. The authenticated media files have an associated string value. Generally, the authentication device is used to scan a barcode on a media sample, determine a string value from the scanned barcode, generate a string value based on fragments of the media sample, and determine a string value from an authenticated media file on the authentication server. The authentication device then concatenates the barcode string value with the generated string value, and it concatenates the authentication string value with the generated string value. A hash function is applied to the concatenated string values, and the resulting hash values are compared. The authentication device causes to be displayed an indication that the media sample is authentic when the hash values match.
