Steganography Scheme Based on LSB Embedding Technique with Different Image Format
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 6
Abstract
To increase the security of messages sent over internet steganography is used. Various steganography techniques have been proposed so far. Least Significant Bit steganography is one such technique in which least significant bit of pixels of the image is replaced with data bits. This approach has the advantage that it is simplest one to understand, easy to implement and results in stego-images that contain embedded data as hidden. The disadvantage of Least Significant Bit is that it is vulnerable to stego analysis and is not secure at all. So as to make it more secure, the least significant bit algorithm is modified to work in different way. The proposed method performs a selection of suitable direction for secret byte embedding so as to minimize the bit changes in the cover image when a secret data is embedded. This paper reports a new algorithm for LSB (Least Significant Bit) replacement based image steganography for RGB color images. The directional aspects of embedding data are explored to develop an improved LSB embedding technique.
