Problems And Countermeasures Of Current DNA Database In Combining Investigation

In recent years,criminal suspects in the criminal investigation of the increasing awareness of the crime scene left fingerprints,footprints and other traces of the use of lower value,the suspects are more choice to video surveillance blind spot crime.The emergence of DNA technology to break the traditional method of physical evidence test,gene stability and objectivity to make the technology more scientific.As more and more cross-regional cases,modern investigation more focus on the work of the case,through the introduction of more public security business elements,such as: network monitoring,video detection,DNA technology,etc.,the traditional investigation and was injected into the new The contents of the investigation and conduct a combination of investigation and carry out investigation work.And the investigation of the case for rape,theft,robbery cases,due to the poor nature of the case,increased social instability,cross-regional crime characteristics of the investigation to increase the greater difficulty to determine the suspect and the victim’s identity as a case Key link.With the DNA technology in the detection of play an increasingly important role in the storage and retrieval as one of the database also came into being.DNA as the most stable and accurate identification of individual identification,the classification of the results into a DNA database is the most important component.The combination of detection and DNA database greatly improves the efficiency of the investigation work and also promotes the detection of some major cases.However,there are some technical problems and human factors in the process of DNA database construction,such as the relevant laws:The lack of privacy protection,technology research and development and demand are incompatible with these,these have become obstacles to the work of the case.Based on this,this paper attempts to explore the DNA database in the investigation and application of the problems and countermeasures,analysis of the DNA database at home and abroad in the investigation of the use of the status quo,database problems,database operation problems,from vigorously carry out DNA database The construction of the database,improve its network use ability,improve the resource sharing platform and other aspects of the DNA database in the investigation and use of the future development trend.This article divides the introduction and conclusion,it is divided into four parts.The first part is an overview of the DNA database.This part includes the theoretical basis of DNA database,such as: DNA typing technology,the same identification theory,elaborated the DNA database and the relationship between investigation and investigation.This paper discusses the background of the establishment of DNA database in China: the emergence of more and more series of cases,the maturity of the biophysical evidence extraction and the increasing popularity of network applications have laid a good foundation for the establishment of the database.Describe the necessity of establishing a database from a theoretical perspective.The second part is the application of DNA database in the investigation of domestic and foreign cases.This section describes the use of DNA databases in the Hong Kong Special Administrative Region and Anglo-American countries and the implications for our country.This paper expounds the database types which are mainly used in the investigation of the case,and analyzes the important role of the DNA database in the investigation of the case by means of the case form,and concludes with the technical investigation means such as video detection and network monitoring.The third part is the DNA database in the investigation and use of the existence of the problem.This part introduces the lack of foundation for the investigation of the case investigation,including the lack of corresponding construction conditions,and the construction of Y-STR DNA database is slow.This paper discusses the shortcomings of the database itself in the investigation of the use of the case investigation by analyzing the problem that the database network is restricted and the copyright infringement is involved in the retrieval.This paper focuses on the shortcomings of the DNA database not fully forming the resource sharing and practice departments in the use of DNA database,emphasizing the urgency of improving the database supervision system.The fourth part is the DNA database in the investigation and application of the perfect.This paper discusses how to lay the foundation for database retrieval in the investigation of the database by strengthening the construction of the primary DNA database and the Y-STR database.It is proposed to improve the network utilization ability of DNA database,to deal with the relationship between database utilization and rights protection,and to improve the database sharing platform.For the public security organs to improve the comprehensive utilization of the database capacity and through the legislation to improve the database monitoring system,also elaborated his point of view.
