The messaging service WhatsApp has announced plans to implement end-to-end encryption for Android phones. WhatsApp gained popularity as a pro-privacy alternative to text messaging. However, privacy concerns were raised after Facebook's proposed acquisition of the company. EPIC filed two complaints with the Federal Trade Commission, urging the FTC to block the sale unless adequate privacy safeguards for WhatsApp users were established. The Commission then notified Facebook and WhatsApp that they must honor their privacy commitments to WhatsApp users. Now, WhatsApp has adopted the Open Whisper Systems protocols to ensure that users' messages are encrypted from sender to receiver and not simply between the user and the service provider.
