  • Method and apparatus for achieving fine-grained access control with discretionary user revocation over cloud data
    Patent number: 11310041
    Abstract: A method for a data owner to enforce attribute-based and discretionary access control over a cloud-based data store by specifying an access policy, creating a plurality of users with attributes that satisfy the access policy, and revoking one or more of the plurality of users by embedding their respective identities as revoked into a ciphertext, whereby only those of the plurality of users whose attributes satisfy the access policy and that are not revoked can decrypt the ciphertext.
    Type: Grant

  • System and method for adding semantic support to existing syntactic infrastructure
    Patent number: 7933764
    Abstract: UDDI is not capable of handling semantic markups for Web services due to its flat data model and limited search capabilities. The present invention provides semantic service description and matchmaking with registries that conforms to UDDI specification. Specifically, the present invention stores complex semantic markups in UDDI data model and uses that information to perform semantic query processing. The present invention does not require any modification to the existing UDDI registries. The add-on modules reside only on clients who wish to take advantage of semantic capabilities. This approach is completely backward compatible and can integrate seamlessly into existing UDDI infrastructure.
