Abstract
A method of verifying integrity of a digital file includes receiving the digital file subsequent to exposure to a foreign environment and validating the digital file. The received digital file has an appended signature label that includes one or both of a first hash value and a digital signature. Validating the digital file includes hashing the digital file to obtain a second hash value, retrieving the first hash value from the signature label, and comparing the first hash value and second hash value.
