Secure delivery of secret data on the Internet is an important research topic in digital
communications. Data encryption and steganography are two common techniques used for …

Steganography is a technique that conceals secret data into a cover medium for delivering
secret data over public computer networks. Reversible data hiding schemes not only can …

Reversible data hiding, in which the stego-media can be reversed to the original cover
media exactly, has attracted increasing interests from the data hiding community. Recently …

In recent years, much research has been focused on the delivery of secret data in
communications networks. Steganography is commonly used to ensure the successful …

Reversible data hiding is a technique that embeds secret information into a host media
without loss of host information. Ni et al.'s histogram shifting technique is a high-quality …

In this paper, we propose an efficient data hiding scheme based on reference pixel and
block selection to further improve the embedding performance of histogram shifting …

Data hiding is a technology that communicates the secret data by the multimedia carrier,
such like image, audio, and video files. A good data hiding scheme can hide huge secret …

Data hiding is a process of hiding information. There are various techniques used for hiding
data. Data hiding can be done in audio, video, image, text, and picture. This method is …

Reversible data hiding, which can restore the original image from the marked image after
extraction of hidden message, has drawn more attention recently. This paper proposed a …

In this paper, a novel reversible data hiding technique based on exploiting modification
direction algorithm is proposed. First, binary secret messages are converted into a sequence …
