METHOD AND SYSTEMS FOR COLLECTING ADDRESSES FOR REMOTELY ACCESSIBLE INFORMATION SOURCES
First Claim
1. A method of collecting addresses for remotely accessible information sources for use in updating a filtering system (100) which controls access to such information sources via a public access network (N1), the method comprising;
- interrupting transmission of a message destined for a terminal (T2, T3) other than the filtering system (100);
identifying an address for a remotely accessible information source from the message;
analyzing the message on the basis of an attribute of the message so as to classify the message as either a first type of message or a second, different, type of message; and
if the message is classified as the first type of message, transmitting a filter message comprising data indicative of the identified address to the filtering system (100).

Abstract
A method and system are described for collecting addresses for remotely accessible information sources. Messages, such as emails, carried by a messaging network (N1) are intercepted before reaching a destined terminal. Addresses for remotely accessible information sources (i.e. URLs) are identified from the intercepted email messages. The messages are analysed to be classified as either a first type of message (e.g. spam or virus messages) or a second, different, type of message. If the intercepted message is classified as the first spam/virus type then data indicative of the identified address (URL) is transmitted to a filtering system (100) which controls access to the remotely accessible information sources. As a result, addresses (URLs) are gleaned from transmitted messages such as spam e-mail and supplied to a filtering system (100) which controls access to the resources accessible at those addresses.

13. A message processing system (103) for use in updating a filtering system (100) which controls access to remotely accessible information sources via a public access network (N1), the message processing system (103) comprising:
-
an interface (205) for receiving a message destined for a terminal (T2, T3) other than the filtering system (100); and a message processor (207) arranged to identify an address for a remotely accessible information source from the message, the message processor (207) being arranged to analyze the message on the basis of an attribute of the message so as to classify the message as either a first type of message or a second, different, type of message; wherein the interface (205) is arranged to transmit a filter message comprising data indicative of the identified address to the filtering system (100) in the event that the message is classified as the first type of message.
