A new model by researchers at Columbia Engineering can encrypt photos uploaded to cloud services including Google Photos and iCloud without making any change to the services. Encrypting photos on the cloud is a difficult task as most cloud services are not compatible with existing encrypting techniques. For example, Google Photos compresses uploaded files to reduce their sizes, but in the process, it would corrupt encrypted images. Now, a team of researchers at Columbia Engineering have developed a new technique to encrypt photos on popular cloud-based storage services, including Google Photos, Apple and Flickr. Called Easy Secure Photos (ESP), the technique encrypts photos uploaded to the cloud service, making it difficult for both hackers and cloud service providers to decipher.
