The scientific study of privacy-preserving biometrics, represented by the palmprint, face, and
iris, has grown tremendously. That being said, there has not been much attention paid to the …

Images with sensitive content require encryption for storage and transmission. Symmetric
schemes can cipher them, while an asymmetric cryptosystem can distribute the secret key …

Recently, many existing image encryption schemes suffer from security vulnerabilities due to
system key leakage. In response to this issue, this paper proposes a novel asymmetric …

With the innovation of high-throughput big data storage technology and the construction of
digital information systems in media applications, images are the common and most popular …

Today, safeguarding sensitive content through encryption is crucial. This work presents a
hybrid cryptosystem for images that employs both asymmetric and symmetric encryption …

High leakage power consumption has become one of the main concerns of data security
protection with CMOS device scaling. Spintronic technology is one of the efficient solutions …

This paper proposes a new cipher image transmission system in free space optics system
(FSO). A secure and effective image cryptosystem algorithm based on the Choquet fuzzy …

The exchange of digital images on the internet has become more convenient, but it has also
led to increasing security concerns. Image encryption differs from text encryption, as inherent …

This paper offers an efficient hybrid image encryption algorithm based on an elliptic curve
cryptography (ECC), skew tent map and hyperchaotic system in order to enhance the …

The picture archiving and communication system is a powerful mechanism to store and
securely transmit images and reports. The development of a cost-effective encryption …
