LSB Steganography Mechanism to Hide Texts Within Images Backed with Layers of Encryption

Steganography is defined as the practice of writing hidden messages in ordinary text, pictures, etc. The proposed methodology can be implemented using any image in jpg (jpeg) or png format and text as input and generates the text embedded within the image as output. In this work, the retrieval of the original text on the receiver's side without any loss of data is discussed. To further strengthen the security of text being transmitted, two classical encryption techniques, namely Substitution and Transposition ciphers are implemented. The major contribution of this work is towards discovering an efficient way of hiding texts within images using LSB Steganography,
