In the context of data protection regulations, I would like to open a discussion on the technical and procedural implementations for handling subject access requests (SARs). Specifically, my inquiries are as follows:
What are the recommended technical strategies for verifying the identity of a requestor to ensure that SARs are processed securely without inadvertently disclosing sensitive information to unauthorized individuals?
How should organizations integrate legacy systems and modern cloud-based architectures in order to retrieve all relevant personal data during a SAR, especially when data is stored in disparate formats or locations?
What are the best practices for maintaining immutable audit trails during the SAR process, and how can such trails be leveraged to demonstrate compliance in the event of an audit or investigation?
Are there any specific challenges or considerations when automating portions of the SAR workflow, particularly with respect to ensuring the accuracy and completeness of the information retrieved?
I look forward to insights and shared experiences on these topics, particularly those that address both technical and regulatory compliance perspectives.
