LSB Based Text and Image Steganography Using AES Algorithm

Abstract

The steganography is the art of hiding data in another data. Secret information like messages, images, audio and video can be hidden inside the cover image. The main objective is to hide the secret message or image inside the image using Least Significant Bit (LSB) technique. To protect and provide security for the hidden message or image, Advanced Encryption Standard (AES) Algorithm is used. Various image formats with different text length or image size are compared. Efficiency of algorithm is estimated by Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE) where higher PSNR value gives the high-quality image. Steganography plays an important role in applications like medical, military, OTP (One Time Password), copyright etc.
