As we are in the age of ubiquitous computing and communication, the need to provide safety
and security for such systems is more urgent than ever. Research works of cryptography …

In recent years, image encryption has been broadly researched. Since a large proportion of
images on Internet are compressed, and JPEG is the most widely adopted standards for …

Permutation is a commonly used primitive in multimedia (image/video) encryption schemes,
and many permutation-only algorithms have been proposed in recent years for the …

Compression and encryption are often performed together for image sharing and/or storage.
The order in which the two operations are carried out affects the overall efficiency of digital …

Protection on end users' data stored in Cloud servers becomes an important issue in today's
Cloud environments. In this paper, we present a novel data protection method combining …

This paper proposes a novel framework of reversible data hiding in encrypted JPEG
bitstream. We first provide a JPEG encryption algorithm to encipher a JPEG image to a …

With increasing use of mobile devices, photo sharing services are experiencing greater
popularity. Aside from providing storage, photo sharing services enable bandwidth-efficient …

While most techniques of reversible data hiding in encrypted images (RDH-EI) are
developed for uncompressed images, this paper provides a separable reversible data …

Video encryption has been heavily researched in the recent years. This survey summarizes
the latest research results on video encryption with a special focus on applicability and on …

In this paper a commutative watermarking and ciphering scheme for digital images is
presented. The commutative property of the proposed method allows to cipher a …
