How application protects images?
All images are crypted “on the fly” using SSL encryption and a key, generated each time the user download an image. Encryption key never repeats. By default RSA encryption is used for keys, and AES-256 encryption is used for downloaded files. But this also can be customized (see more about customization of software).
After encrypted file is downloaded it would be decrypted by a client application in memory (no temporary files created) and viewed inside internal viewer, which is copy-protected.
No Print Screen Key can be pressed, no external capturing software can access client application. The only way to copy image is to picture the screen with the camera . But this is too complicated…
Each software package (client + server) protected with newly generated cryptographic keys, so two different servers can’t view each other contents.
