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.

24. A system for securely delivering data, comprising:
-
a first computer based component comprising computer instructions embedded in a computer hardware platform having a computer processor that executes the computer instructions to create a electronic container having electronic content and an electronic container identifier; a second computer based component comprising computer instructions embedded in a computer hardware platform having a computer processor that executes the computer instructions to encrypt at least one data block of the electronic content using a symmetric encryption technique and to encrypt at least one header associated with at least one data block of the electronic content using an asymmetric encryption technique, the at least one header including a symmetric decryption key; and wherein the at least one data block is configured to be decrypted and accessed by an entity or a device based on an authentication of a device or the entity associated with the electronic container identifier.
