A novel watermarking algorithm for resistant geometric attacks using feature points matching

Abstract

Purpose

Aims to report a novel method of estimating the geometric manipulation to which present day data hiding is subjected.

Design/methodology/approach

Computes the feature points matching measure for the geometric manipulation using shape‐specific points. The feature points matching is realized by simulated annealing algorithm.

Findings

Finds that the purposed scheme does not require the original image because reference point information on the original image has been contained in the secret key.

Originality/value

Experiments herein have proved the method's robustness in face of geometric attacks and a new way of designing a better blind secret message decodes has been revealed.
