Fading data could improve privacy

Privacy could be enhanced if data was allowed to fade, suggests research.
Dutch researcher Dr Harold van Heerde is looking into ways to gradually "degrade" the information that sites gather about visitors.
Slowly swapping details for more general information can help guard against accidental disclosure, he said.
"There are so many weak points in security that you can never be sure that your data is safe," said Dr van Heerde.
