ESP’s key management makes it simple to authorize multiple user devices to view encrypted image content via a process similar to device pairing, but using the cloud photo service as a QR code communication channel. ESP efficiently generates and displays encrypted thumbnails for fast and easy browsing of photo galleries from trusted user devices. ESP encrypts image data such that the result is still a standard format image like JPEG that is compatible with cloud photo services. ESP introduces a new client-side encryption architecture that includes a novel format-preserving image encryption algorithm, an encrypted thumbnail display mechanism, and a usable key management system. For general users, the best Google Photos alternatives outside of more regular cloud storage services are Flickr (in second place) and Amazon Photos (in fourth).
We have created Easy Secure Photos (ESP) to enable users to protect their photos on cloud photo services such as Google Photos.
As users store more and more photos in the cloud, significant privacy concerns arise because even a single compromise of a user’s credentials give attackers unfettered access to all of the user’s photos. New paper: “ Encrypted Cloud Photo Storage Using Google Photos.”Ībstract: Cloud photo services are widely used for persistent, convenient, and often free photo storage, which is especially useful for mobile devices. Storing Encrypted Photos in Google’s Cloud
