摘要
论文针对电子海图在应用中面临的数据安全问题,提出一套以非对称加密和可逆数字水印技术为核心、综合采用信息隐藏和USB密钥管理等软硬件手段的电子海图数据安全解决方案。该方案可有效克服现有海图安全技术的缺陷,全面实现数字海图的防伪、防篡改和流失途径追踪等功能,为电子海图的发放、管理提供可靠的安全保障。
Towards the security issue of digital chart data ,a solution is presented based on asymmetric encryption and digital watermarking .Both information hiding techniques and USB encryption equipments are utilized in our scheme .The proposed scheme can avoid the weaknesses of most current security methods and ,furthermore ,achieve more comprehensive security functions such as anti-fake ,anti-tamper ,and illegal-copy chasing .Consequently ,it can provide a more reliable pro-tection for digital chart data .
