Advanced Hieroglyphic Braille Transpixelation (AHBT): A Novel Approach to Secure Image Steganography

Modern correspondence protection is highly in demand for the protection of information exchange, mainly by means of cryptography and steganography. In this paper, a new method called Advanced Hieroglyphic Braille Transpixelation, or AHBT, is proposed and introduced. AHBT amalgamates Braille and hieroglyphs into a very complex algorithm of information hiding in digital images. The plaintext message will first be translated into hieroglyphics and Braille, then encrypted into 8-bit and 6-bit binary formats, correspondingly. These are camouflaged with columnar transposition and hidden inside the 2 LSB of pixel components (r, g, b) using LSB steganography, storing 6 bits of data per pixel. Experimental results have proven AHBT to improve in data security and visual quality compared to conventional methods, evidenced through higher PSNR rates. This technique is a revolution in personal information protection, as it has used multilevel encryption, steganography, and ancient scripts in combination for better security and privacy.
