In this paper, we are going to have a survey on one of data hiding techniques called "Reversible Data Hiding (RDH)". Due to this, basic principles and notions of RHD are introduced. Also, primary techniques as the principles of RHD are talked. They are: Pair-Wise Logical Computation (PWLC) data hiding technique and Data Hiding by Template ranking with symmetrical Central pixels (DHTC) technique...
With the wide spread utilization of biometric identification systems, establishing the authenticity of biometric data itself has emerged as an important research issue. The fact that biometric data is not replaceable and is not secret, combined with the existence of several types of attacks that are possible in a biometric system, make the issue of security/integrity of biometric data extremely...
Reversible data hiding, in which the stago-media can be reversed to the original cover media exactly, has attracted increasing interests from the data hiding community. In this study, the existing reversible data hiding algorithms, including some newest schemes, have been classified into three categories: 1) Those developed for fragile authentication; 2) Those developed for achieving high data ...
We propose a video data embedding scheme in which the embedded signature data is reconstructed without knowing the original host video. The proposed method enables high rate of data embedding and is robust to motion compensated coding, such as MPEG-2. Embedding is based on texture masking and utilizes a multi-dimensional lattice structure for encoding signature information. Signature data is em...
Reversible Data hiding is a process of hiding information into a cover image. There are various techniques used for hiding secret data. Audio, video, image, text, and picture can be used as a cover medium in data hiding. In images, Reversible Data Hiding (RDH) is a method which is very helpful in the recovery of original cover after the inserted message is extracted. This vital method is broadl...
