Design of Information Hiding Software Based on One-step Bézier Curve
Abstract
Along with the rapid development of information technology, the network already affects society's politics, economical, cultural, military and social life and so on, and it has become the main constituent of the global information infrastructure. But the network takes as a “double-edged sword”, in humanity information society's advancement, has brought the enormous challenge for the safeguard information security. As an important branch of information security, information hiding technology has a better hiding and operating, gradually becomes the focus of information security domain.
At first, this paper analyzes and researches the application of the picture aerial region, discusses with emphasis based on one-step Bézier curve, and proves the usability of this algorithm; Next this algorithm is improved partly, the programming of the information hiding and restore-function are realized; Finally through the test and the analysis, the software can carry on the hide and information and restoration to the data stream information; As a result of this algorithm reasonable design, as an BMP file of carrier, it can hide approximately its 3/8 capacity of plain information, which shows this software has some practical values.
Key words: Information Hiding Technology; Aerial Region of Picture; One-step Bézier curve; Hiding Proportion; BMP
