摘要:
随着科技水平的不断提高,各行各业对气象数据的需求越来越大。 技术发展给气象数据共享带来便利的同时,也给气象数据的非法泄露、篡改和滥用的责任追查带来困难。 目前,气象数据的安全保护措施还比较匮乏,为了有效解决这一问题,提出了一种高效的可行性方案——INVIEN。 该方案能够根据不同的气象数据类型,自适应地采用不同的隐写嵌入算法,将授权用户的用户信息以隐写的方式嵌入原始数据文件中。 该方案不仅可以有效解决数据共享后该数据的原授权用户信息不易追查的问题,还可以为数据所有者版权追溯提供必要的技术支撑依据。 经过反复测试和试验,该方案可以应用于 TXT 格式和 PNG 格式的气象数据中。 通过多次实验分析发现,该方案处理批量数据非常高效、隐蔽。
Abstract:
With the continuous improvement of science and technology,the demand for meteorological data from all walks of life is increasing. While the technical development brings convenience to the sharing of meteorological data,it also brings difficulty to the responsibility tracing of illegal leakage,tampering and abuse of meteorological data. At present,meteorological data security protection measures are still relatively scarce. In order to effectively solve this problem,an efficient and feasible scheme - INVIEN is proposed. According to different weather data,we use different digital watermarking encryption algorithms to add authorized usage information of data in different locations. Through the decryption and analysis of digital watermark,we can track the weather data of authorized users. This scheme can not only effectively solve the problem that it is difficult to trace the original authorized user information of the data after data sharing,but also provide necessary technical support for the copyright tracing of the data owner. The experimental model is applied to the weather data in TXT and PNG formats. It is found that this scheme is very efficient and covert in processing batch data.
