地理大数据安全技术研究现状与展望

Research Status and Prospect of Security Technology for Geographic Big Data

大数据时代背景下,数据的大规模生产、分享和应用带来了新的安全隐患。地理大数据相较于其他大数据特有的性质是具有时空属性,而带有时空信息的数据泄露所造成的影响更加恶劣且损失也更加严重,因此地理大数据的安全保护尤为重要。目前,针对地理大数据的安全保护技术按照保护原理可分为事先防范和事后追究两类,主要包括加密技术、数字水印技术和访问控制技术。本文首先对这三种技术的研究现状进行了总结与评价,然后通过分析多种数据保护技术融合的研究前景,对地理大数据的安全研究提出展望。

In the era of big data,the mass production,sharing and application of data bring new security risks.Compared with other big data,geographic big data has the spatiotemporal attribute,and data leakage with spatiotemporal information has a worse impact and more serious loss.Therefore,the security protection of geographic big data is particularly important.At present,the security protection technology for geographic big data can be divided into two types according to the protection principle,which are advance prevention and after investigation,mainly including encryption technology,digital watermarking technology and access control technology.This paper firstly summarizes and evaluates the research status of these three technologies,and then puts forward a prospect for the security research of geographic big data by analyzing the research prospect of the fusion of various data protection technologies.
