Rumormongers always use long paragraphs to spread slanderous stories so that they can convince readers. Those illegal or sensitive rumors uploaded into the internet can be written on images to by-pass text filters. These images can be detected by existing filters such as OCR, but the detection is very time consuming. To prohibit the dissemination of those commentaries, detecting whether an image contains...
This paper proposes a novel data hiding method for authenticating binary images through establishing dense edge adaptive grids (EAG) for invariantly selecting good data carrying pixel locations (DCPL). Our method employs dynamic system structure with carefully designed local content adaptive processes (CAP) to iteratively trace new contour segments and to search for new DCPLs. By maintaining and updating...
This paper presents a novel lossless data embedding algorithm for electronic inks. The proposed algorithm first computes the analytical ink-curve for each stroke as a set of smoothly concatenated cubic Bezier curves. During embedding, a set of data carrier points on the ink-curve are evaluated, perturbed, and then inserted into the original point array. Our proposed smooth ink-curve generation method...
