Abstract
One exemplary embodiment involves receiving a request for a document key for accessing a document on a client device. The request comprises a user identity identifying a requester requesting access to the document. The request also comprises information about the document. The exemplary embodiment further involves determining, at the server, whether access to the document by the requester is permitted. And, the exemplary embodiment further involves, if access to the document is permitted computing, at the server, the document key using the user identity and using the information about the document. The document key is document specific and, prior to the computing of the document key, the document key is not stored for access by the server. The exemplary embodiment further involves responding to the request by providing the document key for use in accessing the document on the client device.
