Secure image data transmission and hiding technique: a survey

Security is the need of today’s era. In every field like data management, data communication, e-commerce etc. The security task is being complicated as there are variety of data to secure as different level of data security is needed based on the data type. In this paper we have discussed and analyse the image data security. Image cryptography, data hiding, image entropy and image XOR. Based on these parameters we have analysed the previous research work and discussed the advantages and gaps.
