A Dutch researcher is suggesting that privacy could be enhanced if data were allowed to fade. Dr. Harold van Heerde, is looking for ways to gradually degrade the information that sites gather about visitors. He says that slowly swapping details for more general information can help guard against accidental disclosure. The BBC reports the research looked into ways to change the way databases manage information about users and customers. Instead of simply refusing to use services that gather data, researchers believe it would be better for people to surrender data knowing that there was a policy that determined how it degraded over time.
