Secure Text/Image Data Hiding in Images with Efficient Key Management

Anjaly Mohanachandran, Mary Linda P.A.

Abstract: The security plays an important role in transmission of confidential data over internet. So, as a part of improving security in data transmission, we will hide the data inside an encrypted image. Thereby, confidentiality of the image as well as the embedded data is maintained. The embedded data can be extracted without any error, and also the cover image restoration is also free from error. So, here we are implementing a system in which text data can be embedded inside an encrypted image for security and also cover image can be send separately to the destination by hiding it inside another image. It maintains the excellent property that the original image can be losslessly recovered after embedded data is extracted. The major application of this method is medical imagery, military where both data and cover image is confidential. The most improved technique of data hiding is that we can make use of separate keys in case of encryption and data hiding in sender side and receiver side. Thus the concept of efficient key management improves the security.
