In the trial of the case regarding Facebook's disclosure of user information in California, the court filed on May 25 a new lawsuit accusing Facebook of collecting users and their friends’ information with the APP. At this point, the safety of big data around the world has attracted widespread attention.
Data from Gemalto showed that about 1.9 billion data records were leaked out worldwide in the first half of 2017. Compared to the last six months of 2016, the number of lost, stolen or leaked records increased by a staggering 164 percent, in which a large portion came from the 22 largest data breaches, each involving more than one million records.

Up to 96.6 percent of Android apps get users' mobile phone privacy rights and for iOS apps, the number is 69.3 percent. In addition, 25.3 percent of Android apps even obtain users’ mobile phone privacy rights illegally.
“Some companies cannot make accurate judgments on the importance of data, so data is not protected properly based on data level.”said Lu Baohua, an information security expert, adding that though the country has explicit stipulations on hierarchical protection of data to ensure data security and privacy, companies are allowed to classify and protect data independently in specific implementation and thus some companies may abuse data.
“The issue of big data security is still severe. At present, relevant departments are accelerating the supplement and improvement of a series of laws, regulations and systems such as network security law.” Qing said.
