To Improve Legal Issues Of Electronic Evidence Research Based On Cloud Computing Forensic In China

Innovations in technology bring new economic and social development.Since Google announced a worldwide cloud plan in 2007,the majority of IT industry,government,and enterprise have identified cloud computing as one of the major strategies for future development."cloud computing White Paper" released by China Center for Information Industry Development shows cloud computing services market is increasing year after year,up to $ 152.8 billion in 2014.Cloud computing fully embodies the "network is the computer".Information storage and processing are carried out over the network in the cloud,which causing users to worry about data security in cloud computing environment.When the illegal invasion and information leakage threaten the legitimate rights and interests of the right holder,it is necessary to collect,preserve and fix the electronic evidence in the cloud computing environment.However,how to obtain effective electronic data evidence in cloud computing environments is a huge challenge for investigators.How to obtain valid evidence of electronic data has always been the hotspot of scholars which has not reached a definitive conclusion yet.The service form of cloud computing environment to produce and store electronic data is different from that of computing or LAN.Therefore the traditional “one to one” evidence model is not completely applicable to the former.Collecting electronic data in a cloud computing environment often affects third-party interests.As it is often difficult for forensic personnel to determine the exact location of the large cloud computing storage server,the technology of data collection in long-distance becomes one of the common ways of data acquisition.In this case,what is collected is more likely to be a replica instead of raw data.To consistency between raw data and a copy one,further rules of evidence and regular instructions are needed to acquire,fix,store,analyze and display evidence.Therefore,it is necessary to study and perfect the legal issues related to electronic data forensics in cloud computing environments.This article takes the rules of electronic data collection as its basic point,considering evidence law,litigation law,investigation and cloud computing features at the same time.Comparing and researching thoroughly domestic and foreign laws and regulations and relevant legal issues of cloud computing forensics,the author puts forward some suggestions.Above all,this paper starts from the basic theory of electronic data forensics in cloud computing environment.By considering domestic and foreign laws and regulations on cloud computing forensics and specific certification rules,it brings out problems in electronic data forensics in cloud computing environment,including a set of legal issues.For example,the jurisdiction principle remains elusive,privacy data protection needs to be enhanced,forensic procedures need to be further improved,the proof of digital evidence is inevitably biased and devoid of relevancy.Finally,based on the guarantee of the authenticity,legitimacy and relevance of the electronic evidence collected in the cloud computing environment,this paper puts forward the rules of electronic data evidence in the cloud computing environment and the legal improvement measures related to the electronic data collection in the light of our current legal policy.This paper studies and expounds the fields related to cloud computing and digital data.Then it conducts a comprehensive,systematic,comprehensive analysis of cloud computing evidence of the relevant legal issues.From the adoption of the rules of electronic evidence and the improvement of relevant legislation,we clearly understand that the electronic evidence in the cloud computing environment is more reliable.
