1. A content filtering system for filtering content retrieved from an Internet computer network by individual controlled access network accounts, said filtering system comprising:
- a local client computer generating network access requests for said individual controlled access network accounts;
at least one filtering scheme;
a plurality of sets of logical filtering elements; and
a remote ISP server coupled to said client computer and said Internet computer network, said ISP server associating each said network account to at least one filtering scheme and at least one set of filtering elements, said ISP server further receiving said network access requests from said client computer and executing said associated filtering scheme utilizing said associated set of logical filtering elements.

Abstract
A method and system for filtering Internet content retrieved from an Internet computer network (110) by a remote Internet Service Provider ("ISP") server (100) and forwarded to a local client computer (10). The method and system matches at least one filtering scheme (121), such as an inclusive or exclusive filter, and at least one set of filtering elements (120), such as a list of allowed or excluded sites, to each Internet access request generated at the local client computer (10). The filtering scheme is implemented on the ISP server (100).

18. An ISP server for filtering content forwarded to controlled access network accounts accessing an Internet computer network from a remote client computer, said remote client computer generating network access requests containing a destination address, said ISP server comprising:
-
a plurality of sets of logical filtering elements, each controlled access network account being associated with at least one set of said plurality of sets of logical filtering elements; and at least one filtering scheme associated with each controlled access network account, said associated filtering scheme for determining whether to allow said network access request based on said at least one logical set of logical filtering elements. - View Dependent Claims (19, 20, 21)

22. An ISP server for filtering content forwarded to controlled access network account generating network access requests at a remote client computer, each network access request including a destination address field, said ISP server comprising:
-
a master inclusive-list of allowed sites; a plurality of sets of exclusive-lists of excluded sites, each controlled access network account associated with at least one set of said plurality of exclusive-lists of excluded sites; and a filtering scheme, said filtering scheme allowing said network access request if said destination address exists on said master inclusive-list but not on said at least one associated exclusive-list, whereby said controlled access accounts may be uniquely associated with one or more sets of excluded sites. - View Dependent Claims (23)

24. A method for filtering content retrieved from an Internet computer network by a controlled access account, said method comprising the steps of:
-
transmitting a network access request associated with said controlled access account from a local client computer; receiving said network access request at a remote ISP server; associating said network access request with a set of logical filtering elements from a plurality of sets of logical filtering elements stored remotely from said local client; executing a filtering scheme on said ISP server, said filtering scheme utilizing said associated set of logical filtering elements; and transmitting said network access request from said ISP server to said Internet computer network if said filtering scheme accepts said network access request and transmitting a rejection from said ISP server to said client computer if said filtering scheme denies said network access request. - View Dependent Claims (25)
