A Review on Reversible Data Hiding Techniques
نویسنده
چکیده
Reversible data hiding (RDH) has been intensively studied in the community of signal processing. Also referred as invertible or lossless data hiding, RDH is to embed a piece of information into a host signal to generate the marked one, from which the original signal can be exactly recovered after extracting the embedded data. The technique of RDH is useful in some sensitive applications where no permanent change is allowed on the host signal. In this paper, a survey on various data hiding algorithms has been discussed. From the survey, it has been concluded that none of the protocol performs effectively in all fields. Therefore the paper ends with the future scope to overcome these issues.

متن کاملA Survey on Data Hiding Techniques in Encrypted Images
The transmission of confidential data over the network requires more security. So, for improving security in data transmission, we can hide the data inside an encrypted image. Hence the confidentiality of the image and the data embedded in the image is maintained. The data embedded can be extracted without any error, and also the cover image can be restored with error free. This type of techniq...
