Encryption technology is vital because it gives copyright owners an additional degree of protection against misappropriation.4 Using cryptography to protect intellectual property raises questions related to the strength of algorithms used to encrypt and decrypt digital objects. Specifically, the use of weak cryptography to protect exported digital objects could well result in considerable financial damage to the original creators of intellectual property.5 If it proves reasonable to protect intellectual property through encryption, pressures may well grow to allow stronger cryptography to be deployed worldwide so that creators of intellectual property can market their products safely and without fear of significant financial loss.
