Image encryption techniques play a significant role in multimedia applications to secure and
authenticate digital images. This paper presents a comprehensive study of various image …

In this paper, we present a robust and secure watermarking approach using transform
domain techniques for tele-health applications. The patient report/identity is embedding into …

In this paper, by using Logistic, Sine and Tent systems we define a combination chaotic
system. Some properties of the chaotic system are studied by using figures and numerical …

In this paper, a digital image encryption algorithm is proposed based on the generalized
model of the chaos game. The chaos game is a well-known fractal, which acts as a pseudo …

In this paper, a distinctive Hybrid Adaptive Image Encryption (HAIE) scheme is proposed that
utilizes some statistical parameters of the plain image like mean and variance to modify the …

The explosive generation of data in the digital era directs to the requirements of effective
approaches to transmit and store the data. The necessities of security and limited resources …

Hyperchaotic maps are generally used in the encryption to generate the secret keys. The
number of hyperchaotic maps has been implemented so far. These maps involve a large …

In this paper, a chaotic based secure medical image watermarking approach is proposed.
The method is using non sub-sampled contourlet transform (NSCT), redundant discrete …

The holistic concept of smart cities has been adopted to increase economic, environmental,
and social sustainability. For the sustainable health of a smart city inhabitant, there is a …

At the present time, the protection of multimedia data has become a very important process
which can be achieved by encryption. Basically, so many different techniques have been …
