ABSTRACT:
A method and system to delegate an authority to access collaborative resources are provided. The system enables a participant to re-delegate the authority to another participant by an authorization certificate. A chain of authorization certificates is established along with the re-delegation of the authority from one participant to another. The participant requesting access to the collaborative resources is requested to provide the owner with the chain of authorization certificates for verification. Therefore, the re-delegation process may be performed without the need to notify the owner and yet without comprising the security of the collaborative resources.
