Text-To-Image Steganography is a steganography technique to hide information such as text messages inside a given image file by manipulating bits of the original image file. The technique has been implemented using LSB Algorithm where the least significant bit of the original image is replaced with the given message bits. LSB algorithm in this project has been implemented for red color channel data for given RGB image files. The original image bits are extracted and replaced with the message bits and the image is saved and retrieved to pull back the information from the stego-image. In order to maintain the integrity of the secret message the lossless compression is used to save the carrier image to stego-image. In order to make the stego-image undetectable to the naked eye LSB algorithm has been used. The performance of the algorithm is tested in RGB and grayscale images.
