A study from computer scientists at Columbia Engineering reveals what may be the first way to encrypt personal images on popular cloud photo services, such as those from Google, Apple, Flickr and others, all without requiring any changes to - or trust in - those services.

Cloud photo services currently not compatible with image encryption.

Even if compression worked on encrypted images, mobile users of cloud photo services typically expect to have a way to quickly browse through identifiable photo thumbnails, something not possible with any existing image encryption schemes.

A number of third-party photo services do promise image encryption and secure photo hosting, but these all require users to abandon existing widely used services such as Google Photos.

Now researchers have created a way for mobile users to enjoy popular cloud photo services while protecting their photos.

The system, dubbed Easy Secure Photos, encrypts photos uploaded to cloud services so that attackers - or the cloud services themselves - cannot decipher them.
