Patent ID: 8356115

Claim:
A computer-implemented method for preserving computer user attribute data, said method for use in a computer network including a plurality of servers, and a plurality of clients having a network browser, said method comprising the steps of: storing the user attribute data in two or more data locations, said user attribute data being associated with a client; receiving, at a client from a server, instruction code which is code executable by the client or code self-executing in the client, and which is configured to cause the user attribute data to be preserved; determining synchronization of the user attribute data stored in said two or more data locations responsive to receipt of the instruction code; synchronizing the user attribute data stored in said two or more data locations to preserve the user attribute data if said stored user attribute data is not already synchronized to preserve the user attribute data; determining a lack of synchronization of the user attribute data stored in a first of said two or more data locations with the user attribute data stored in a second of said two or more data locations; and responsive to determining the lack of synchronization of the user attribute data stored in the first and second of said two or more data locations, restoring the user attribute data in the first of said two or more data locations so that the user attribute data in the first and second of said two or more data locations is synchronized.
