Security Using LSB & DCT Steganography In Images

  title={Security Using LSB \& DCT Steganography In Images},
  author={Deepak Singla and Rupali Syal},
Abstract Steganography is a technique of hiding information in digital media. In contrast to cryptography, it is not to keep others from knowing the hidden information but it is to keep others from thinking that the information even exists.In this paper, we propose a LSB & DCT-based steganographic method for hiding the data. Each bit of data is embedded by altering the least significant bit of low frequency DCT coefficients of cover image blocks. There are some techniques to utilizes the idea… Expand
