An open source software group, Open Whisper Systems , has announced the release of Signal 2.0 — the second version of its free and open source messaging application for iPhone and iPad users. Signal  app is specifically designed to make secure and easy-to-use encrypted voice calling. But that's what the application was providing in its previous release introduced last July with  Signal 1.0 . Apple's iMessage also provides encrypted communication, but it was challenged by security researchers in 2013, revealing that  Apple controls the key infrastructure  and could, in turn, be compelled to change a key anytime they want, and read the content of your messages. But there was no way to send secure messages from an iPhone iMessage to an Android phone, or vice versa, unless you signed up for a monthly subscription plan and got the person you wanted to communicate with to sign up for it too. GAME CHANGER: SIGNAL 2.0 Signal 2.0 lets you send end-to-end encry...

Do you know that your Facebook account can be accessed by Facebook engineers and that too without entering your account credentials? Recent details provided by the social network giant show who can access your Facebook account and when. No doubt, Facebook and other big tech companies including Google, Apple and Yahoo! are trying to keep their data out of reach from law enforcement and spies agencies by adopting encrypted communication and end-to-end encryption solutions in near future, but right now they have access to your personal data, and at least few of their employees can access it with one click. Earlier this week, director at the record label Anjunabeats, Paavo Siljamäki , brought attention to this issue by posting a very interesting story on his Facebook wall. During his visit to Facebook office in LA, a Facebook engineer logged into his Facebook account after his permission, but the strange part — they did it without asking him for the password. ACCESS WITHOUT...
