Cambridge Analytica is a dirty, Dementor-focused big data research outfit that provided the analysis and psych profiles that the Trump campaign used in its electioneering; because its parent company is in the UK, it is required (under EU law) to send you its dossier on you for £10.
Various privacy advocates have been trying to get Cambridge Analytica to comply with UK privacy rules for some time; the company has finally started obeying the law, and PersonalData.io's Paul-Olivier Dehaye lays out a roadmap for forcing the company to cough up yet more of the data it holds on us and the psychological profiles it has derived from this data.
Dear Data Compliance Team at SCL Group,
Under the purview of EU Data Protection Directive 95/46/EC and Data Protection Act 1988, I wish to:
know whether your company or any of its processors hold any of my personal data (this includes Cambridge Analytica and other companies in the SCL Group);
know the legal basis of such processing, for each of those companies holding my data (if you rely on consent, please be specific on when I might have given consent and how);
know how you classify this data into the different categories recognized by applicable data protection regimes;
know for what purposes you process this data;
know the legal bases of potential transfers of such personal data to the United States, for each vendor;
for each vendor, obtain my own identifiers within that vendor's systems;
for each data point, obtain full information as to its source;
get an explanation on the "logic of the processing" of my personal data;
get a list of recipients of my personal data;
obtain a copy of all my personal data.
It has now been a long time since I initially asked for my data. I trust that you will do your best to respond promptly to my request. Given undue delays incurred so far, a response time below a week seems reasonable.
I particularly wish to attract your attention to the "General provisions relating to offences" articles in the Data Protection Act 1988, as they pertain to liabilities by body corporates, but also the personal liability of any officer in such body.
