Electronic data relation chain generation system and method based on social network data chain

Abstract

The invention provides an electronic data relation chain generation system and method based on a social network data chain. The system comprises a judicial authentication terminal, a data timestamp authentication terminal, a data access device, a visualized engine and an application data server, wherein the judicial certification terminal is used for generating a judicial certification login signal; the data timestamp authentication terminal receives the authentication timestamp label; the data access device associates and then stores the authentication timestamp label and the acquired electronic data; and the visualized engine generates a visualized electronic data relation chain generated based on the social network data chain based on the electronic data information stored in the data access device. The method generates a visualized electronic data relationship chain map based on social network data of at least one mobile terminal. According to the technical scheme, an artificial intelligence technology, a knowledge graph technology and a data mining algorithm are applied, a suspect physical and virtual identity relation network is constructed, and case visualization is achievedfrom multiple dimensions such as time, space, social contact and capital.

Description

technical field [0001] The invention belongs to the technical field of electronic evidence processing, and in particular relates to a system and method for generating an electronic data relationship chain of a social network data chain. Background technique [0002] In the era of the Internet of Everything, mobile smart terminals and applications have become important carriers for committing crimes, and the electronic data in smart terminals and their applications has become an important source of evidence for the public security to crack cases. [0003] In recent years, with the popularization of mobile smart terminals and 4G networks, the world has entered the era of mobile Internet, and the Internet has become more and more developed, but cybercrime is becoming the "Sword of Damocles" of the Internet. Statistics show that 60% of online fraud originates from mobile devices, and of these 60% fraud, 80% originate from mobile applications. Once a cybercriminal gains access...

Problems solved by technology

[0011] However, it has been found in practice that relying solely on forensic equipment cannot meet the data analysis requirements

On the one hand, more and more data are stored on mobile smart terminals. There are hundreds of thousands or even millions of WeChat chat records stored in a mobile phone. The evidence clues in the case are submerged in a large amount of invalid data. Key pieces of clues need to be quickly mined and retrieved through analysis software; on the other hand, if the data itself is incomplete (which is the most common case, as criminals usually delete information in time), the above existing technologies cannot be used ; Even if the judiciary often requires the data service provider to provide data, it usually directly submits the mobile phone itself to the data service provider, so that the data service provider cannot clearly know what kind of data the judiciary needs and how to legally provide the data. In addition, the relationship network of criminal suspects is intricate, and there are correlations between application data such as calls, text messages, instant messaging, Weibo, geographic information, and e-commerce on mobile smart terminals. How to solve complex relationships? Quickly locating the path of criminal clues in the network also requires the support of analysis software
