An anonymous reader writes MIT researchers believe the solution to misuse and leakage of private data is more transparency and auditability, not adding new layers of security. Traditional approaches make it hard, if not impossible, to share data for useful purposes, such as in healthcare. Enter HTTPA, HTTP with accountability.
From the article: "With HTTPA, each item of private data would be assigned its own uniform resource identifier (URI), a component of the Semantic Web that, researchers say, would convert the Web from a collection of searchable text files into a giant database. Every time the server transmitted a piece of sensitive data, it would also send a description of the restrictions on the data’s use. And it would also log the transaction, using the URI, in a network of encrypted servers."
