The development of artificial intelligence (AI) technology has given rise to a new threat in the legal sphere, namely deepfakes. The emergence of deepfake technology as a sophisticated form of digital forgery poses serious legal challenges, particularly regarding the position of electronic evidence in the judicial process. This technology enables the creation of electronic evidence—such as audio, images, or videos—that appears highly authentic yet is entirely fabricated or manipulated. This study aims to analyze the legal challenges posed by deepfakes concerning the validity and verifiability of electronic evidence within the justice system. Employing a normative legal research method with statutory and conceptual approaches, the findings indicate that deepfakes generate complex legal challenges. These primarily concern: (1) Authenticity and Integrity Aspects, where the boundary between genuine and fabricated evidence becomes blurred; (2) Evidentiary Aspects, particularly in meeting statutory standards for valid electronic evidence; and (3) Procedural Law Aspects, manifesting in the difficulties faced by judges and litigating parties in examining the authenticity of deepfake evidence in court. This research concludes that the existing legal framework, including the Information and Electronic Transactions (ITE) Law, remains inadequately equipped to address the vulnerabilities exploited by deepfake technology. Therefore, strengthening regulations, establishing technical standards for digital forensic verification, and enhancing the capacity of law enforcement agencies are imperative to confront these challenges.
