One alternative method for giving individuals better control over their data, who can access and for what purpose, could be the use of personal data stores or ‘data vaults’. The concept of such a ‘personal store’ requires security mechanisms that ensure that only those entities authorised by the data subject can access the data and only those parts for which they are authorised. Personal data stores would be most effective where they concern current and constantly updated information, such as geospatial data or signs of life. Beyond the technical safeguards, data users would be obliged to respect the rules about data sharing and use. (Quelle: Towards a new digital ethics Data, dignity and technology)
