Least Significant Bit Hash Algorithm for Digital Image Watermarking Authentication
Stella D. Muyco, Alexander Arcenio Hernandez · 2019
Recent advancements in data security like images, audio, and video have shifted the focus of security from using cryptography to steganography or both. Steganography, the most widely used technique is the Least Significant Bit method which is simply and yet vulnerable to attacks. However, the study of modifying the Least Significant Bit method would be challenging or impractical to look at the hidden message domain where the process of extensive study must be done. However, due to its simplicity of the Least Significant Bit method, this technique could be easily modified, but the challenge is how you will modify with the digital image will be safety and integrity which is the top issue on information explosion. This study provides novelty on digital watermarking using least significant bit hash algorithm and is analyzed using data capacity analysis, histogram analysis, and hamming distance.
