Recently, diagnosing diseases using medical images became crucial. As these images are
transmitted through the network, they need a high level of protection. If the data in these …

Images are very important forms of data that are widely used nowadays. Every day, millions
of grey and color images are transferred via the web. Protecting these images from …

Aiming at the problems of small key space and weak resistance to differential attacks in
existing encryption algorithms, we proposed a chaotic digital image encryption scheme …

The fractional-order functions show better performance than their corresponding integer-
order functions in various image processing applications. In this paper, the authors propose …

In the age of Information Technology, the day-life required transmitting millions of images
between users. Securing these images is essential. Digital image encryption is a well-known …

The advent of the Internet led to the easy availability of digital data like images, audio, and

To protect the medical images integrity, digital watermark is embedded into the medical
images. A non-blind medical image watermarking scheme based on hybrid transform is …

With the widespread use of color images, the copyright protection of those images using
watermarks is one of the latest research topics. The use of color images as watermarks has …

The single watermarking algorithm for medical images faced several inherent problems like
lack of security. In this paper, a new geometrically invariant multiple zero-watermarking …
