Information Hiding Technology in Electronic Notes System

This paper starts from security needs of electronic notes in the present situation of e-commerce and discusses the application of information hiding technology and relative concepts. Then it presents a algorithm of information hiding technology that applies in the electronic notes system, including embedded hidden information algorithm and hidden information extraction algorithm, and describes the idea of the algorithm. Finally, the paper discusses realization of the e-ticketing system based on information hiding technology, and points out the security that information hiding technology brings to the system, so that the e-ticketing system gets with the security needs of e-commerce in authentication, notes anti-counterfeiting, tamper-resistant features.
