From Annex 2 of wp248 rev.01 Guidelines on Data Protection Impact Assessment (DPIA) and determining whether processing is “likely to result in a high risk” for the purposes of Regulation 2016/679 at http://ec.europa.eu/newsroom/document.cfm?doc_id=47711:
Annex 2 – Criteria for an acceptable DPIA
The WP29 proposes the following criteria which data controllers can use to assess whether or not a DPIA, or a methodology to carry out a DPIA, is sufficiently comprehensive to comply with the GDPR:
- a systematic description of the processing is provided (Article 35(7)(a)):
- nature, scope, context and purposes of the processing are taken into account (recital 90);
- personal data, recipients and period for which the personal data will be stored are recorded;
- a functional description of the processing operation is provided;
- the assets on which personal data rely (hardware, software, networks, people, paper or paper transmission channels) are identified;
- compliance with approved codes of conduct is taken into account (Article 35(8));
- necessity and proportionality are assessed (Article 35(7)(b)):
- measures envisaged to comply with the Regulation are determined (Article 35(7)(d) and recital 90), taking into account:
- measures contributing to the proportionality and the necessity of the processing on the basis of:
- specified, explicit and legitimate purpose(s) (Article 5(1)(b));
- lawfulness of processing (Article 6);
- adequate, relevant and limited to what is necessary data (Article 5(1)(c));
- limited storage duration (Article 5(1)(e));
- measures contributing to the rights of the data subjects:
- information provided to the data subject (Articles 12, 13 and 14);
- right of access and to data portability (Articles 15 and 20);
- right to rectification and to erasure (Articles 16, 17 and 19);
- right to object and to restriction of processing (Article 18, 19 and 21);
- relationships with processors (Article 28);
- safeguards surrounding international transfer(s) (Chapter V);
- prior consultation (Article 36).
- risks to the rights and freedoms of data subjects are managed (Article 35(7)(c)):
- origin, nature, particularity and severity of the risks are appreciated (cf. recital 84) or, more specifically, for each risk (illegitimate access, undesired modification, and disappearance of data) from the perspective of the data subjects:
- risks sources are taken into account (recital 90);
- potential impacts to the rights and freedoms of data subjects are identified in case of events including illegitimate access, undesired modification and disappearance of data;
- threats that could lead to illegitimate access, undesired modification and disappearance of data are identified;
- likelihood and severity are estimated (recital 90);
- measures envisaged to treat those risks are determined (Article 35(7)(d) and recital 90);
- interested parties are involved:
- the advice of the DPO is sought (Article 35(2));
- the views of data subjects or their representatives are sought, where appropriate (Article 35(9)).

In July 2020, the CNIL (DPA for France) published guidelines on data retention (Guide pratique – Les durées de conservation). https://www.cnil.fr/sites/default/files/atoms/files/guide_durees_de_conservation.pdf
These reflect early CNIL recommendations from 11-Oct-2005 on the archiving of personal data.
They aim to provide practical help to define the data retention rules and periods.
Similar to DIN-66398 (German industry standard on data retention/deletion) they don’t include guidance on specific data categories. https://din-66398.de/
However, CNIL does define data retention periods in separate dcouments (“Référentiel”). Up to now, two such Référentiels have been published for the health sector:
The EDPB just published the long-awaited successor of WP 169 of 2010:
Guidelines 07/2020 on the concepts of controller and processor in the GDPR
The CNIL publishes a GDPR guide for developers
In order to assist web and application developers in making their work GDPR-compliant, the CNIL has drawn up a new guide to best practices under an open source license, which is intended to be enriched by professionals.

“If processing of sensitive ‘special category’ data is necessary as part of performing the contract, controllers will also need to identify a separate exception to the general prohibition of processing such data, because contractual necessity alone does not fulfil the requirements of Article 9 GDPR. Thus, as with all processing of such special category data, the controller will need both a legal basis – in this case, necessary for the performance of a contract – as well as fulfilling a condition under Article 9(2) which allows for the processing that type of personal data – such as the fact that the data have been ‘manifestly made public’ or the processing is necessary to establish, exercise, or defend a legal claim.”
