Improved Bit Plane Splicing LSB Technique for Secret Data Hiding in Images Using Linear Congruent Method

Free registration required

Executive Summary

In this paper, the authors propose two algorithms based on the popular Bit Plane Splicing Least Significant Bit (LSB) Technique for secret data hiding inside images. One major disadvantage of Bit Plane Splicing LSB technique is its low hiding capacity which results in severe degradation of the cover image upon hiding large amount of data. The proposed algorithms overcome this issue by imposing hiding rules based on the intensity level of pixels. In addition the method for data hiding is done in a non-sequential manner using linear congruent random number generators.
