Arrest warrants are crucial tools in the process of apprehending and prosecuting suspects according to the law. Therefore, arrest warrant data must be accurate and reliable. Currently, various organizations involved in the criminal justice system in Thailand are incorporating technology to manage arrest warrant data. However, the arrest warrant data from each organization may not align with the arrest warrant data from the Off ice of the Judiciary. Outdated arrest warrant data can lead to wrongful arrests, violating the rights and freedoms of individuals. The author proposes studying ways to address this issue by developing the arrest warrant information system to a single platform for managing arrest warrant data by using blockchain technology. Blockchain is considered eff icient and trustworthy in ensuring data integrity, as it prevents unauthorized tampering or modif ication of data. Research methods include documentation analysis and interviews with executives or representatives and off icials of government organizations involved in the criminal justice, as well as interviews with experts in technology and bureaucracy government organizations, such as Off ice of the Public Sector Development Commission and Digital Government Development Agency. Research f indings suggest that while using blockchain technology to manage arrest warrant data on a unif ied platform may not be suitable due to the nature of arrest warrant issuance by the courts and the sole ownership of this data by the Off ice of the Judiciary, there have been no reported issues of falsif ied or unauthorized modif ications to arrest warrants. Each organization already has its own systems for managing arrest warrant data, which operate differently. Therefore, using a unif ied platform would not address concerns about data security and other operational challenges. Instead, it is suggested to address the current issues with arrest warrants by utilizing existing technology and systems in each organization, while improving them to solve the problems, such as data linkage through API. This approach would be more cost-effective and benef icial compared to using blockchain
technology, as it would yield similar results.
