Title: Method of using electronic tickets containing privileges for improved security

Abstract: A server system provides a client system with a number of on-line services including a log-in service. Once the server receives a request from the user for initiating access to the server, the log-in service accesses a user database for information including access privileges of the authorized user in relation to the other services available on the server. The server then generates an information packet containing this information, and transmits the information packet to the client. The client than transmits a second request to the server, requesting use of another service offered by the server. The information packet provided by the server in response to the log-in request is transmitted along with the second request to the server. The server then regulates access by the client to this other service by using the information packet transmitted back to the server from the client. Thus, access to the user database is minimized.
