In the last few years, with the increasing popularity of cloud computing and the availability of
mobile smart devices as well as ubiquitous network connections, more and more users are …

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 …

For joint image compression and encryption schemes, the encryption power and
compression efficiency are commonly two contradictory things. In this paper, we propose a …

Many new DCT-like transforms have been proposed since the first edition of this book. For
example, the integer DCT that yields integer transform coefficients, the directional DCT to …

The rising popularity of social networks and cloud computing has greatly increased a
number of JPEG compressed image exchanges. In this context, the security of the …

Recovering unknown, missing, damaged, distorted, or lost information in DCT coefficients is
a common task in multiple applications of digital image processing, including image …

The security protection of Ultra-High-Definition (UHD) video is facing grand challenges due
to changeable application scenarios. The video business is highly dependent on the video …

High Efficiency Video Coding (HEVC) encryption, which has been proposed to encrypt intra
prediction modes (structural information), transform coefficients (texture information), and …

As cloud storage becomes more popular, concerns about data leakage have been
increasing. Encryption techniques can be used to protect privacy of videos stored in the …

With the increasing emphasis on security and privacy, video in the cloud sometimes needs
to be stored and processed in an encrypted format. To facilitate the indexing and tampering …
