中文摘要：

随着信息技术的发展,以Web2.0技术为基础的博客、微博、社交网络等新兴服务和物联网以前所未有的发展速度产生了类型繁多的数据,而云计算为数据的存储提供了基础平台,这一切造就了大数据时代的正式到来.大数据中蕴藏着巨大的价值,是企业的宝贵财富.但大数据同时也带来了巨大的挑战,个人隐私保护问题就是其中之一.迅速发展的互联网已经成为人们生活中不可或缺的一部分,人们在网络上留下了许多数据足迹,这些数据足迹具有累积性和关联性,将多处数据足迹聚集在一起,就可以发现个人的隐私信息.恶意分子利用这些信息进行欺诈等行为,给个人的生活带来了许多麻烦或经济损失,因此大数据的个人隐私问题引起了工业界和学术界的广泛关注.首先介绍了大数据时代个人隐私保护的相关概念,讨论了个人隐私保护面临的挑战和研究问题;然后从数据层、应用层以及数据展示层叙述了个人隐私保护所使用的技术,探讨了个人隐私保护的相关法律以及行业规范的几个重要方面;最后提出了大数据个人隐私保护的进一步研究方向.

英文摘要：

With the development of information technology, emerging services based on Web2.0 technologies such as blog, microblog, social networks, and the Internet of things produce various types of data at an unprecedented rate, while cloud computing provides a basic storage infrastructure for big data. All of these lead to the arrival of the big data era. Big data contains great value. Data become the most valuable wealth of the enterprise, but big data also brings grand challenges. Personal privacy protection is one of the major challenges of big data. People on the Internet leave many data footprint with cumulativity and relevance. Personal privacy information can be found by gathering data footprint in together. Malicious people use this information for fraud. It brings many trouble or economic loss to personal life. Therefore, the issue of personal privacy has caused extensive concern of the industry and academia. However, there is little work on the protection of personal privacy at present. Firstly, the basic concepts of big data privacy protection are introduced, and the challenges and research on personal privacy concern are discussed. Secondly, the related technology of privacy protection is described from the data layer, application layer and data display layer. Thirdly, several important aspects of the personal privacy laws and industry standards are probed in the era of big data. Finally, the further research direction of personal privacy protection is put forward.
