TL;DR: The proposed fully recoverable encrypted and watermarked image technique was used to authenticate and secure the medical images in health information systems and the results showed to be very effective and reliable for fully recoveredable images.

TL;DR: This paper proposed a fully recoverable encrypted and watermarked image processing technique for the security of medical images in health information systems and showed to be very effective and reliable for fully recoveredable images.

TL;DR: An encryption technique of securing the biometric image data collected from devices with an approach of feature based encryption technique based on a visual cryptographic technique is proposed.

TL;DR: A hybrid image cryptographic encryption and digital watermarking technique was proposed for the encryption and authentication of digital image content and the image was successfully reconstructed without any loss of pixel value after decryption.

TL;DR: This paper proposed a robust, efficient and fully recoverable encrypted-compressed image based on hybrid discrete cosine transformation and visual cryptographic technique for securing digital images and proved to be an efficient way of encrypting images and compressing them for other channels without the worry of visual loss.
