Abstract: A method for programming a key for selectively allowing access to at least one enclosure having a lock controlled by a lock controller is disclosed. The method comprises: detecting the key; identifying the key by a static key number and a key user; identifying the at least one authorized enclosure corresponding to the identified key; loading the at least one authorized enclosure identification onto the key; generating a plurality of date sensitive key access codes; and loading the plurality of date sensitive key access codes in the key.

Abstract: An access control technique to limit access to information content such as available on the Internet. The technique is implemented within a network device such as a proxy server, router, switch, firewall, bridge or other network gateway. The access control process analyzes data in each request from the clients and determines if the request should be forwarded for processing by a server to which it is destined. Access control may be determined by comparing client source information against a database of Uniform Resource Locators (URLs), IP addresses, or other resource identification data specifying the data requested by the client. The invention therefore provides access control not based only upon content, but rather, based primarily upon the identity of the computers or users making the requests. The technique further avoids the problems of the prior art which categories or filters the content of only web pages based solely upon objectionable words.
