Abstract

DNA technology, as a more scientific method of physical evidence testing, is playing an increasingly important role in solving criminal cases. With the wide application of DNA, DNA has become one of the key evidences of forensic science. The DNA database is closely related to the investigation work. The combination of the DNA database and the investigation can not only improve the efficiency of the case investigation, but also promote the detection of major cases. The extensive application of DNA technology has promoted the development of DNA database. With the continuous expansion of database, the problem of intelligent management level and sufficient sharing between libraries is becoming more and more prominent. This paper discusses the problems existing in the application of database in the investigation of parallel cases and emphasizes the importance of perfecting the database supervision system. The relationship between database application and rights protection is analyzed, and finally the supervision system of DNA database is proposed through legislation.
