Privacy Protection of Digital Images Using Watermarking and QR Code-based Visual Cryptography
Algorithm 1
Algorithm for image watermarking phase.
| INPUT: Secret Image (C1) and watermark image (WI) | | OUTPUT: Watermarked secret image (WC) | (1) | Select secret image CI | (2) | Perform wavelet decomposition and get WCI | (3) | Split the selected wavelet WCI1, WCI2, WCI3, and WCIn | (4) | Select the watermark image (WI) | (5) | Split the binary watermark in blocks B1, B2, B3, …, Bn | (6) | Embedding the watermark blocks into the selected wavelet coefficients | (7) | Get the resulting values after embedding the watermark | (8) | Perform wavelet reconstruction to get the watermarked image | (9) | Stop |
