This article examines the legal and forensic problems of authenticating digital evidence in cybercrime investigations through a comparative legal analysis. The study compares the Federal Rules of Evidence, the Daubert and Frye standards, European approaches to electronic evidence, the procedural framework of the Budapest Convention and the national practice of Uzbekistan. Authentication is considered not as a single technical act, but as a continuous procedural and technical process aimed at proving the source, integrity, unchanged condition and relevance of digital evidence to the criminal event. The article analyzes the risks of manipulation, the difficulty of comparing volatile data such as RAM with an original source, errors arising from forensic tools and the problem of attributing digital activity to a specific person. The article concludes that Uzbekistan needs a unified methodological standard for authenticating digital evidence and a stronger practical use of hashing, forensic imaging and chain of custody mechanisms.
