ABSTRACT:
A system and method of encrypting digital content in a digital container and securely locking the encrypted content to a particular user and/or computer or other computing device is provided. The system uses a token-based authentication and authorization procedure and involves the use of an authentication/authorization server. This system provides a high level of encryption security equivalent to that provided by public key/asymmetric cryptography without the complexity and expense of the associated PKI infrastructure. The system enjoys the simplicity and ease of use of single key/symmetric cryptography without the risk inherent in passing unsecured hidden keys. The secured digital container when locked to a user or user's device may not open or permit access to the contents if the digital container is transferred to another user's device. The digital container provides a secure technique of distributing electronic content such as videos, text, data, photos, financial data, sales solicitations, or the like.
