High-capacity reversible data hiding in binary images using pattern substitution

Privacy protection of fingerprint database using lossless data hiding

“…The locations of the patterns with low frequency will be recorded and used for reconstructing the original image. Similar to [8], Xuan et al…”

“…Furthermore, the host image bit pairs can be recovered from the stego bit pairs. Ho et al [8] propose a approach based on pattern substitution in the difference image. Two groups of patterns are utilized in their technique, i.e., patterns with high frequency and patterns with low frequency.…”

“…Consider a single pixel P 0 located at ith row and jth column of the fingerprint template. We denote the eight neighbors of P 0 in Figure 2 as P 1 , P 2 , P 3 , P 4 , P 5 , P 6 , P 7 and P 8 . In what follows, we denote "1" as the foreground (black) pixel and "0" as the background (white) pixel.…”

“…In order to reconstruct the original image after data embedding, some lossless binary image data hiding techniques are proposed in [7,8,9]. Tsai et al [7] propose a lossless data hiding technique based on pair-wise logical computation.…”

Reversible Data Hiding Scheme via Recursive Codes for Grayscale and Binary Covers

“…Celik et al [2] predict multiple LSB planes and enhances the scheme proposed in [1]. However, many other researchers used the idea presented in [1] for RDH into binary images [3], [4] or videos [5], [6].…”
