Abstract

A method, apparatus, and system provide the ability to determine a validity of a file. A static image of a first version of the file is output. The outputting includes determining first identifying information that identifies the first version of the file, generating a first reference identifier that is associated with the first identifying information, storing the first reference identifier, and generating the static image that includes a visual representation of the first reference identifier. A second reference identifier (that is associated with second identifying information that identifies a second version of the file) is received. Based on the second identifying information, a determination is made regarding which version of the file is more recent. A validity or invalidity of the second version of the file is confirmed based on the determination.
