摘要
交通数据因其数据覆盖广泛、数据动态及时更新的特征被广泛应用于金融、保险等场景。在数据流通中如果缺乏完善的数据安全防护措施,就会存在数据泄露和数据贬值风险。本文提出了一种基于椭圆曲线加密的二值图像可逆水印算法,创造性地运用了图像仿射变换,将数据映射为一张预设的水印图像上的像素点,通过像素点和数据记录之间一对多的映射关系来实现鲁棒性。作者在数据交易场景中应用验证了方案的高效性和可行性。
Traffic data is widely used in finance,insurance and other scenarios because of its extensivedata coverage,dynamic and timely data update.If there is no perfect data security protection measures in the data circulation,there will be data leakage and data devaluation risk.In this paper,a reversible watermarking algorithm protected by elliptic curve encryption is proposed,which creatively uses image affine transformation to map data to a preset watermark image,and the robustness is achieved through one-to-many mapping between one pixel and the data records.
