摘　　要：随着电子技术和互联网技术的发展和广泛应用,涉及电子证据的犯罪案件与日俱增.由于存储技术的迅速发展,取证人员往往无法在限定时间内完成对大容量存储介质的取证工作,针对这种取证时间和设备不足以应对取证需求的困境,本文借鉴军事医疗类选的思想设计了电子证据评估算法,根据案情对电子证据进行价值评估,然后根据证据价值大小决定取证顺序,以此提高电子取证的工作效率.With the development and extensive application of IT technology, crimes related to the digital evidence have increased dramatically. Owing to the rapid development of storage technolo- gy, ,sometimes investigators can＇t finish carrying out investigation and obtaining evidence in a limited time. In the face of the plight of lack of time and forensic resource, the paper proposes an evaluation algorithm of digital evidence which is based on the military medical triage. By using the algorithm to evaluate the digital evidence and determine the forensic priority based on the value of evidence, we can increase the efficiencv of digital forensics.
