A New Image Steganographic Technique using Pattern based Bits Shuffling and Magic LSB for Grayscale Images
This work addresses the need for enhanced information security in image steganography, though it appears incremental as it builds on existing spatial domain techniques.
The paper tackles the problem of securely embedding secret information in grayscale images by proposing a new steganographic technique that combines pattern-based bits shuffling and magic LSB embedding, achieving improved effectiveness compared to state-of-the-art methods as validated through experimental analysis.
Image Steganography is a growing research area of information security where secret information is embedded in innocent-looking public communication. This paper proposes a novel crystographic technique for grayscale images in spatial domain. The secret data is encrypted and shuffled using pattern based bits shuffling algorithm (PBSA) and a secret key. The encrypted data is then embedded in the cover image using magic least significant bit (M-LSB) method. Experimentally, the proposed method is evaluated by qualitative and quantitative analysis which validates the effectiveness of the proposed method in contrast to several state-of-the-art methods.
