Deepfakes and Digital Identity Protection: Legal Challenges, Privacy Risks, and Regulatory Responses in the Age of Artificial Intelligence

Abstract

With the rapid and increasing development of artificial intelligence (AI), deepfake technology has emerged to produce highly realistic synthetic audio, images and videos, thus presenting a wide range of possibilities as well as complex legal and social issues (Chesney & Citron, 2019; UNESCO, 2021). These technologies have valuable and legitimate uses in education, entertainment, and digital innovation, but their misuse has raised concerns about digital identity manipulation, privacy violations, misinformation, fraud, reputational harm and loss of trust in the public. While digital identity protection has gained increasing scientific interest, research on it is still scattered, only technical detection methods or only legal aspects are generally studied, and there is a lack of qualitative synthesis on the governance of digital identity and inter-jurisdictional legal aspects. The purpose of this research is to explore, critically analyse and provide a critical discussion of the legal challenges, privacy implications and regulatory responses raised by deepfake technologies, using a qualitative interpretivist methodology. The research uses document analysis, qualitative content analysis, comparative legal analysis, and analysis of the publications and peer-reviewed literature, legislation, judicial decisions, government reports, policy documents, international legal instruments and publications of the UNESCO, OECD, European Union and the Council of Europe. The conclusions reveal four interrelated themes: Emerging legal deficiencies in the protection against synthetic identity manipulation, rising privacy and human rights risks, differences in the national and international regulatory landscape, and the need for AI governance that is transparent, accountable, and rights-based. The analysis shows that the existing legal frameworks and jurisdictional issues are still hindering the effective protection of digital identities in a more connected digital world. Overall, the study makes a significant contribution to the growing body of research on AI governance, by synthesising insights from privacy law, digital identity protection, and regulatory governance, offering a holistic qualitative overview of deepfake regulation. It also provides concrete policy suggestions and measures for the improvement of legal accountability, harmonization of regulatory requirements, and responsible AI innovation while respecting fundamental rights for legislators, regulators, technology companies, and legal practitioners, as well as for policymakers. The authors conclude that there needs to be coordinated international regulatory cooperation, flexible legal frameworks, and human-centered AI governance that can strike a balance between technological innovation and safeguarding privacy, identity and democratic norms (OECD, 2019; UNESCO, 2021).
