摘要： A workflow order is created for the object. Public parameters are received from a key generation center at a computer associated with an object master. A public key is generated at the computer system based on a user identifier and the public parameters, wherein the user identifier is comprised of user related information. The object is encrypted using the public key such that the object cannot be opened without the a private key, wherein the object is a composite document comprising multiple elements of documents of different formats, and wherein the private key is generated in response to a request from an authenticated user using the user identifier at the key generation center. Access to the multiple elements of the object is controlled based on workflow order.

摘要： Detecting a workflow termination. An object with embedded access control is sent to a next participant in a workflow, wherein the embedded access control is provided and enforced by placing a subset of access keys for individual content-parts into a unique key-map entry for each participant, wherein the object is a Publicly Posted Composite Document. A workflow termination is detected after failure to receive a confirmation token from the next participant after a specified condition is not met.
