With the development of technology and the increase in digitalization, the use of data in criminal cases is becoming increasingly important. While law enforcement and prosecutorial authorities try to catch criminals and provide justice by collecting and analyzing electronic evidence during investigations, the protection of personal data of defendants and witnesses is of great importance. This situation necessitates the establishment of a delicate balance between data protection in criminal cases.
The Importance of Data Protection
Data protection in criminal cases basically covers three main principles:
Prohibition of Unlawful Processing of Personal Data: Personal data cannot be processed only for purposes determined by law and without the consent of the relevant person or a legal justification.
Ensuring the Security of Personal Data: Personal data must be protected against unlawful access, use, disclosure, alteration or destruction.
Rights of the Person Concerned with Personal Data: The relevant person has the rights to obtain information, rectify, delete, limit the processing of and object to his/her personal data.
Data Protection Issues in Criminal Cases
Some important issues regarding data protection in criminal cases are as follows:
Collection and Processing of Electronic Evidence: Failure to comply with data protection principles during the collection and processing of electronic evidence by law enforcement and prosecutorial authorities.
Sharing of Personal Data: Sharing personal data with third parties unrelated to the criminal case.
Cyber Security Vulnerabilities: Inadequate protection of data against cyber attacks.
Data Breaches: Unlawful acquisition or disclosure of personal data.
Solution Proposals
The following solution proposals can be considered to ensure data protection in criminal cases:
Strengthening Data Protection Legislation: Aligning criminal procedure laws and other relevant legislation with data protection principles.
Increasing Data Protection Capacity: Employing personnel trained in data protection in law enforcement and prosecutorial authorities and providing the necessary technical infrastructure.
Increasing Transparency and Accountability: Increasing transparency regarding data protection practices and establishing an effective accountability mechanism against data protection violations.
Strengthening International Cooperation: Improving international cooperation on data protection in criminal cases.
