Abstract:

Data hiding is a major issue of concern while exchanging secret information in an untrusted network. Reversible data hiding plays a vital role in secure secret data transmission. For many applications such as medical image processing and military application every bit of data is important .Even a small amount of distortion is unacceptable and any change can affect the intelligence of the image. RDH-EI is the process of hiding secret information in a cover medium and the lossless extraction of the same ensuring increased payload capacity, better protection and better visual quality of the recovered image. This paper presents a survey on various data hiding techniques and related works.
