The way that use double watermark technique , and use asymmetric secret key system and a different secret key during watermark checking gives a novel idea to people : different information can be embedded into the image according to different requirement and provided for multiple utilization , because fragile watermark only require the trusted third part to extract and the user is transparent . the robust watermark required the authentication centre to extract the watermark . at the same time , the zero knowledge proof for the author id can be done by the authentication centre , which is the idea of the cryptology authentication and can solve problem of the copyright ownership more effectively 虽然本文对该模型提出的算法并没有具体实现,但是,在同一幅图像中嵌入鲁棒水印与易损水印的双水印技术,以及采用的非对称密钥体制即在水印嵌入过程与水印检测过程中使用了一对不同的密钥,可为人们提供一个新的思路:由于易损水印只需通过可信任第三方提取,对用户是“可见”的,因此可根据需要嵌入不同的信息,多方利用;鲁棒水印的提取需要认证中心提取,同时可由认证中心对商家身份进行的零知识验证,体现了密码学的认证思想,更能解决版权纠纷的所有权问题。
On this basis , according to water consumption mechanism and process of crops , the relationships , relative influence and effect transferring between various technology on water saving are fully considered . the calculating method of water saving potentialities on basis of the multiple utilization of water resources in irrigated regions is studied . the calculating model on water saving potentialities is set up 在此基础上,根据农作物耗水机理和耗水过程,充分考虑各种节水技术间的相互关系、相互影响和效应传递,研究基于灌区水资源综合利用的节水潜力计算方法,建立节水潜力计算模型,结合对不同阶段灌区节水技术发展水平的预测,定量计算黄河下游引黄灌区不同水平年的节水潜力。
