He called on “all web users to demand better legal protection and due process safeguards” such that the privacy of their online communications is protected and asked them to demand for rights such that they be informed as and “when someone requests or stores their data.”

Closing the statement Berners-Lee noted that personal and sensitive information about a person when stored “is a huge liability” questioned as to “Whom would you trust to decide when to access it, or even to keep it secure?”

The statement and comments from Berners-Lee come after a whistleblower, a former IT contractor who worked at the CIA’s offices in Hawaii, leaked details of an operation dubbed PRISM which was used to covertly snoop on internet users. Through PRISM, NSA officials were able to access information about users of Google, Facebook, Microsoft and quite a few other high-profile web companies.

Edward Snowden, the whistleblower, said, “The NSA targets the communications of everyone. It ingests them by default. Any analyst at any time can target anyone.” Google, Facebook and other tech companies have denied their involvement in the scandal.
