Transparency is key to accountability. One can only guarantee accountability if information about the functioning of the system or device is available in a transparent and proper way. The tool must be designed in such a way that transparency and user control can become a reality .
Furthermore, as the EDPB stated, “in order to ensure their fairness, accountability and, more broadly, their compliance with the law, the ICT tools must be auditable and should be regularly reviewed by independent experts. The application’s source code should be made publicly available for the widest possible scrutiny”. However, this might collide with intellectual property considerations. In any case, developers must ensure that their devices incorporate functions that allow end-users to be fully aware of the processing that will be given to their data.
The source code of the application and of its backend is open, and the technical specifications have been made public, so that any concerned party can audit the code, and where relevant, contribute to improving the code, correcting possible bugs and ensuring transparency in the processing of personal data.
