Research on Criminal Sampling Forensics Under The Background of Big Data

Sampling forensics, as a method of forensics that has long existed in the field of administrative law enforcement, has been gradually extended to the field of criminal proceedings. In the digital age, there is a large number of homogeneous evidence in some cases, in this case, the public security organs or the public prosecution want to carry out comprehensive evidence will undoubtedly lead to the phenomenon of high cost of evidence, low efficiency, or even can not achieve comprehensive evidence. At this time, the proposal of sampling forensics provides a new way to solve the difficulty of obtaining evidence of a large number of homogenous evidence. However, in criminal proceedings, the application of sampling evidence collection is still in its infancy, and there are still various problems. There are still different opinions on the nature, legality and specific procedure norms of sampling forensics in criminal proceedings. Therefore, this paper will focus on the issue of criminal sampling forensics, its nature, rationality and legitimacy, the problems in practice and the construction of criminal sampling forensics applicable procedures and specific norms to launch a discussion.
