The Electronic Frontier Foundation (or EFF) has posted a new Secure Messaging Scorecard, which ranks popular messaging offerings based on their security measures. The Scorecard uses a variety of metrics, such as methods of encryption and user privacy, and Apple's messaging options faired rather well.
While dedicated secure messaging apps like ChatSecure and CryptoCat scored the highest, the EFF found Apple's iMessage and FaceTime systems to be "the best of the mass-market options." The two services were found more secure than several high profile apps, including BlackBerry Messenger and Skype.
