A block-based adaptive data hiding approach using pixel value difference and LSB substitution to secure e-governance documents
T Halder, S Karforma, R Mandal - Journal of Information …, 2019 - koreascience.kr
In order to protect secret digital documents against vulnerabilities while communicating,
steganography algorithms are applied. It protects a digital file from unauthorized access by
hiding the entire content. Pixel-value-difference being a method from spatial domain
steganography utilizes the difference gap between neighbor pixels to fulfill the same. The
proposed approach is a block-wise embedding process where blocks of variable size are
chosen from the cover image, therefore, a stream of secret digital contents is hidden. Least …
