Performance Analysis of Spatial and Frequency Domain Multiple Data Embedding Techniques towards Geometric Attacks

摘要

Data hiding is an age-old technique used to hide data in an image. Several attacks are prevalent to hack the data hidden inside the image. Considerable researches are going on in this area to protect the hidden data from unauthorized access. The current work is focused towards studying the behavior of Spatial and Frequency Domain Multiple data embedding techniques towards noise prone channels enabling the user to select an optimal embedding technique. The Performance of the above techniques is also focused towards multiple embedded data inside a single cover image. The robustness of the watermark is tested by incorporating several attacks and testing the watermark strength.
