SECURE TRANSACTION OBJECT CREATION, PROPAGATION AND INVOCATION

摘要

Functional data for use in one or more digital transactions is secured by using an encapsulated security token (EST). In certain embodiments, the EST is created by encapsulating digital data including the functional data using at least two digital signature systems of two parties. The encapsulation and subsequent de-encapsulation can utilize digital signature systems of the parties that involve a private key for encapsulation and a public key for de-encapsulation. If constructed carefully over a series of rigorous events, the resulting EST can be practically impossible to counterfeit. In addition, a propagation of rights can be tracked for auditing and rights can be easily terminated or modified.
