Enhanced Least Significant Bit (LSB) Algorithm for Steganography

The Least Significant Bit (LSB) algorithm is a steganography technique used to hide data within digital images by modifying the least significant bits of the pixel values.

Our work presented an enhancement to the Least Significant Bit (LSB) algorithm used in steganography for hiding data within images. Traditional LSB methods use all three color channels (red, green, and blue) in a pixel to embed data. The proposed algorithm improves upon this by using only the green and blue channels, minimising noticeable changes in the image's appearance while maintaining data security. Experimental results demonstrate that the algorithm effectively balances image quality and security, successfully hiding data ranging from 8 bytes to 1024 bytes without degrading the cover image.
