| “Authentication is a lawsuit activity in which the evidence through cross-examination in court is reviewed and judged by the fact-finders so that it is determined whether it could be admitted by explaining the reasons.†The fact-finders in the criminal lawsuits of our country are judicial personnel, which include mainly judges and people’s jurors. Authentication rules are the regulations of the activities during which the fact-finders judge the evidence in order to ascertain the facts, and they have important value for the criminal trials, which could ensure the legitimate rights and interests of defendants, victims and other personnel related to the cases, the thorough investigation of a case timely and effectively to restore the truth and bring the real criminals to justice as well as the prevention of misusing power and judicial corruption. Meanwhile, the application of authentication rules could make the parties understand clearly the authentication process, and accordingly appeal no more improving the judicial credibility. However, perfect authentication rules have not been established nowadays in our country. The front-line judges in the field of criminal trials can only grope based on their personal knowledge, experience, and so on. Compared with other evidence of the criminal law, the testimony of witnesses has the characteristic of strong subjectivity. In addition, because of the imbalance of the experience and knowledge level of our country’s judicial personnel it is hardly convincing that the judges just come to a conclusion of adoption or not as to the authenticity and the proving ability of the testimony of witnesses, which therefore leads to misjudged cases sometimes.
