    摘要: One exemplary embodiment involves receiving, at a server, a request for a document key for accessing a document on a client device, wherein the request comprises an identity of an access policy and information about the document. The exemplary method further comprises determining, at the server, whether access to the document is permitted according to the access policy. If access to the document is permitted, the exemplary method involves computing, at the server, the document key using the information about the document, wherein the document key is document specific, wherein, prior to the computing of the document key, the document key is not stored for access by the server. The exemplary method further involves responding to the request by providing the document key for use in accessing the document on the client device.

    摘要: A method and apparatus for automatically administrating access rights for confidential information is disclosure. In one embodiment, access rights are established for at least one user group. Each user group is identified by at least one authentication attribute. In response to verification information from a user requesting access to the confidential information that is stored at a, the verification information is compared with the at least one attribute for the each user group to generate a comparison result. Access to the confidential information by a second computerized device is controlled based on the comparison result and the access rights.
