Once known for distributing hacking tools and shaming software companies into improving their security, a famed group of technology activists is now working to develop a system that will allow the creation of messaging and social networking apps that won't keep hold of users' personal data. From a report: The group, Cult of the Dead Cow, has developed a coding framework that can be used by app developers who are willing to embrace strong encryption and forsake revenue from advertising that is targeted to individuals based on detailed profiles gleaned from the data most apps now routinely collect. The team is building on the work of such free products as Signal, which offers strong encryption for text messages and voice calls, and Tor, which offers anonymous web surfing by routing traffic through a series of servers to disguise the location of the person conducting the search.

The latest effort, to be detailed at the massive annual Def Con hacking conference in Las Vegas next week, seeks to provide a foundation for messaging, file sharing and even social networking apps without harvesting any data, all secured by the kind of end-to-end encryption that makes interception hard even for governments. Called Veilid, and pronounced vay-lid, the code can be used by developers to build applications for mobile devices or the web. Those apps will pass fully encrypted content to one another using the Veilid protocol, its developers say. As with the file-sharing software BitTorrent, which distributes different pieces of the same content simultaneously, the network will get faster as more devices join and share the load, the developers say. In such decentralized "peer-to-peer" networks, users download data from each other instead of from a central machine.
