Biometric databases are among the most promising technologies which have contributed to the emergence Genetic Policing, where biometric data (fingerprint, eye print, facial print, DNA) is stored in advanced electronic systems to identify individuals and detect perpetrators of crimes quickly and precisely, that the INTERPOL expects to revolutionise the field of policing and criminal evidence. In line with this global policing trend, the Sultanate of Oman recently issued the Biometrics Law by Royal Decree (21/2024) and the Royal Oman Police launched Yaqeen Project (the national biometric database system), which is aimed at supporting the efforts of Judicial authorities in investigations and prosecutions to combat crimes and strengthen national security in accordance with the strategic goals of Oman Vision 2040. Given the Sultanate's new experience in this challenging sphere, the research by conducting a descriptive, analytical and comparative approach and through interviews discusses the legal and technical challenges of the law enforcement use of biometrics, specifically those related to genetic privacy, data confidentiality and refusal to provide samples. Is also consider innovative practices to overcome the current challenges, as well as prospects for genetic policing, such as identifying those likely to be involved in a crime and international data exchange to achieve the desired results that the Sultanate seeks to attain in the domain of criminal justice. Indeed, identifying the challenges and prospects associated with the Yaqeen project will not only contribute to developing regulatory procedures and proposing legislative amendments to ensure the optimal utilisation of biometric databases, but will also enhance the chances of establishing a cost-effective policing tool for crime prevention as planned by national visions.
