The Influence of Additive Noise on Information Hiding Based on Linear Carrier
Deng Yu Li, Jun Xiao, Xiao Xu Leng · Applied Mechanics and Materials · 2014
The additive noise is a common type of noise in signal processing. Although its existence does not depend on the input signal, it has a great interference on the useful signal. In the field of information hiding, additive noise and de-noising is also an important research direction and is crucial for the security. In this paper, different information hiding methods of linear carrier are analyzed and the pros and cons of each way are compared. Beside this, a deep research is carried on the effect of Gaussian noise and Salt & Pepper noise on each method. The simulation comparison shows that additive noise has a great influence on information hiding, and under the same noise intensity, the method of hiding information based on the difference of concave and convex square waves has stronger robustness.
