A New Security Framework Of Mobile Two-Dimensional Bar Code Electronic Ticket System-Based On Digital Watermark

Mobile two-dimensional bar code electronic ticket system is a new thing burst from traditional ticket and motion network. The paper has done much profitable research about the security framework of the mobile two-dimensional bar code electronic ticket system and proposed a new security framework of the mobile two-dimensional bar code electronic ticket system, which is based on digital watermark. The paper has also done research about the two-dimensional bar code digital watermark arithmetic, which is suitable for the new security framework; and a novel spatial domain fragile digital watermark scheme has been proposed.The new security framework applies the digital watermark and encryption techniques into the mobile two-dimensional bar code electronic ticket system, adds three new security mechanisms: Electronic ticket binds only one SIM card,Encrypted two-dimensional bar code and Digital watermark identity validation, solves the security problem faced by the traditional electronic ticket system perfectly.First, the new framework uses the watermark as the identity of the electronic ticket, stops the forgery of the electronic ticket radically. Second,...
