Netcop, from Stockport, Cheshire-based Pathfinder Ltd, is extending a long arm into personal computer and on-line pornography. The product is not intended as a picture-deciphering system but instead builds a model of the user’s patterns of access, collating information from phrases used in electronic mail messages, types of newsgroups accessed and typical models of how a voyeur uses his personal computer. Initially aimed at the bedroom market, Netcop is also being groomed for the corporate market. Pathfinder’s Richard Williams confirmed that it will be used in the UK by a major building society which has had some problems with machines clogged with ‘glamour’ pictures. Netcop will be available in November at ú35.
