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...
This paper presents a novel lossless data hiding technique for electronic inks. The proposed algorithm first computes the analytical ink-curve function 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 computed, perturbed and inserted back into the original point array together with some marker points. In extraction,...
