A NOVEL APPROACH FOR SECRET DATA TRANSFER USING LSB BASED STEGANOGRAPHY WITH WATERMARKING

N any communication, security is the most important issue in today’s world. Lots of data security and data hiding algorithms have been developed in the last decade, which worked as motivation for our research. In simple words, Steganography can be defined as the art and science of invisible communication. In this paper we present the combination of LSB steganography and watermarking that will allow an average user to securely transfer secret messages by hiding them in a digital image file using the local characteristics within an image. Watermarking has become a popular technique for copyright enforcement and image authentication. The goal of this paper is to provide the two tier security i.e protectio n against detection and protection against removal. The performance of purposed method is estimated with the parameters PSNR, MSE and results show that this proposed technique is more efficient and secure
