Binary Lower Triangular Matrix based Secure Text Embedding in RGB Images

Text steganography is an efficient method of hidden communication, where the secret text message is embedded into digital images. In this paper, a new method of embedding a text message into an RGB image using a Binary Lower Triangular Matrix (BLTM) is proposed. In the proposed method, the encrypted text bits are embedded into the least significant bits of the RGB components of the image using matrix-based XOR operations. The proposed method improves the security of text embedding while maintaining the image quality. A graphical user interface has been developed using Python.
