Mashup is a representative of Web 2.0 technology that needs both convenience of cross-domain access and protection against the security risks it brings in. Solutions proposed by prior research focused on mediating access to the data in different domains, but little has been done to control the use of the data after the access. In this paper, the authors present Mash-IF, a new technique for information-flow control within mashups. Their approach allows cross-domain communications within a browser, but disallows disclosure of sensitive information to remote parties without the user's permission. It mediates the cross-domain channels in existing mashups and works on the client without collaborations from other parties.
