Title: .B.3. THE RIGHT TO REQUEST CORRECTIONS

The right to request corrections is important to avoid possible mistakes in profiles based on data that are not correct or not up to date. To request these corrections, the data subject should have access to his data and therefore, first needs to be aware who is holding the data where. Today, this has become an impossible task due to the proliferation of data sharing, transfers and dissemination to third parties.  

One possibility to remedy this situation could be to tag personal data with digital rights management (e.g. adding a hash code to the data), but this seems technologically not possible because the DRM functionalities in the data seem to require much more bits and bytes than the personal datum itself. It could be applied to data such as pictures that are built of many bits and bytes. Another possibility could exist in the obligation for data collectors to send a copy to the data subject each time when data are collected, so that the subject has the possibility to contact every data collector to request a change of the data.  This would require almost 100% compatibility and interoperability of personal data tools, devices and databases.
