Abstract
A method and system for granting an applicant associated with a client computer in a client-server system access to a requested service without providing the applicant with intelligible information regarding group membership. The applicant transmits a request for service to an application server over a computer network. In response, the application server prepares an encrypted message which includes the identification of the group or groups having access privileges and transmits the encrypted message to the client along with a request that the client prove membership in at least one of the groups. The message is encrypted with an encryption key which can be decrypted by a group membership server.
