Steganography is the art of secret communication and steganalysis is the art of detecting the
hidden messages embedded in digital media covers. One of the covers that is gaining …

Reversible data hiding (RDH), also known as lossless data hiding, ensures the losslessly
recovery of both the cover medium and the secret message at the decoder. For the video …

With the development of digital video communication, the steganography based on H.
265/HEVC has attracted more and more attention. Because of higher security and better …

Cost assignment plays a key role in coding performance and security of video
steganography. Existing cost assignment methods (for adaptive video steganography) are …

Linguistic steganography (LS) aims to embed secret information into a highly encoded text
for covert communication. It can be roughly divided to two main categories, ie, modification …

Adaptive image steganography is the process of embedding secret messages into
undetectable regions of a cover image through the design of a distortion function by a …

Abstract High Efficiency Video Coding (HEVC) is well-known as an internationally popular
video coding standard, and HEVC-based steganography has received increasing attention …

Distortion compensation method is a common way to cope with the distortion drift problem in
coefficient domain HEVC steganography. However, it will leave obvious steganographic …

Linguistic steganography (LS) conceals the presence of communication by embedding
secret information into a text. How to generate a high‐quality text carrying secret information …

The cost function is crucial to the security of adaptive image steganography, However, some
existing cost functions are heuristically designed and hard to be optimal in the …
