It’s hard to keep secrets in today’s increasingly interconnected, networked world. Social network megasites, mobile phones, webcams and inter-site syndication can broadcast and amplify the slightest fragment of information. Data linking and interpretation tools can put these fragments together, to paint a detailed picture of your life, both online and off.
This online richness creates offline risk. For example, if you’re going away on holiday, there are hundreds of ways in which potential thieves could learn that your home is vacant and therefore a target for crime: shared calendars, twittered comments from friends or family, flickr’d photographs. Any of these could reveal that your home and possessions sit unwatched, unguarded, presenting an easy target for criminals.
Q: What research challenge does this present to the Semantic Web community? How can we address the concern that Semantic and Social Web technology have more to offer Burglar Bill than to his victims?
A1: We need better technology for limiting the flow of data, proving a right to legitimate access to information, cross-site protocols for deleting leaked or retracted data that flows between sites, and calculating trust metrics for parties requesting data access.
A2: We need to find ways to reconnect people with their neighbours and neighbourhoods, so that homes don’t sit unwatched when their occupants are away.
ps. Dear Bill, I have my iphone, laptop, piggy bank and camera with me…
