Abstract: A system and method for authenticating the source of, protecting the contents of, and ensuring the integrity of information. The information may be any digital information which can be stored in a computer file. The information is encapsulated in a computer file which also includes the biometrically verified identity of the person who packaged the information. The contents of the computer file are encrypted, and a unique message digest value is generated and stored in a secure central database. The message digest value functions as the digital signature of the encrypted information, and is used to ensure the integrity of the information.
