While personal data is currently captured and monetized by platforms without real consent, the control and ability of users to act are at the heart of "self data" (or "my data"), with the ambition of placing the user at the heart of the system. Providing real means of control over personal data: this approach has been the subject of experimentation for several years: in France (MesInfos), but also in the United States (My Data Initiatives), in the United Kingdom (midata) and in Finland (MyData Finland).

On July 2, 2019, the Fing and its partners organized at La Caisse des Dépôts et Consignations, the Self Data Territorial event to explore the privileged links between Self Data and territorial authorities. This day provided an overview of urban initiatives on the theme of shared personal data

Metropolis of Lyon

• In November 2016, the MesInfos Hackathon held in Lyon allowed developers, designers or project leaders to think about how to return data to citizens so that they can make good use of it.
• In September 2017, the first self data morning enabled the 120 people gathered in Lyon to discover this theme, the opportunities offered by sharing the power of personal data, and to make a progress report on the MesInfos pilot.
• The project changes scale in 2018 with two thousand volunteer individuals, MAIF, Orange, EDF, GrDf and Enedis. These organizations had committed to return to the two thousand testers all the information collected about them: detailed statement of communications (Orange) to energy consumption recorded by Linky meters (Enedis) or Gazpar (Grdf). The Metropolis of Lyon, for its part, retrocedes water consumption data. Only the user has access to all of this data, which he or she can consult and classify, and which he or she can authorize companies to use in exchange for services. All of this data is gathered in a protected area accessible only to users.
• The theme of social action has been chosen for the next steps: this theme could, later on, overlap with others such as mobility or energy. Three use cases have been developed with the help of social workers.
• The experimentation finally chosen will focus on the " My Social Situation" scenario (with the possibility of extending it, in the long term, to the other two scenarios: " My Direct Assistance" and " Sortia" ) to allow individuals to follow, with social workers, the evolution of their path and their files.

Nantes Metropole

• In order to massify this approach, which only reaches a public that is already aware of the issue, the City of Nantes wishes to rely on a digital tool. Nantes is supported in this approach by La Fing, Ademe and energy companies such as Enedis, EDF, GrDF and Engie.
• Through several workshops, 4 use cases were designed(TechnoZeus, MySmartHome, La Toque Verte and WeMix) based on 3 challenges: " know your energy consumption, help self-consumption and renovation, know your food carbon footprint".
• The City plans to launch an experiment in 2020 with a hundred accompanied testers and a second panel of 1000 participants (less accompanied)

La Rochelle

For its MesInfos experimentation, the city has chosen the theme of mobility, a field where La Rochelle has already innovated a lot. Among the four scenarios of uses envisaged(Coach Co², Shared Mobility, Par 4 chemins, Mon Budget Mobilité), it is finally the Coach CO² and Shared Mobility scenarios that will be tested on a base of 50 testers, agents of the agglomeration or postal workers. The construction of the tools will be based on existing solutions in order to propose operational and reliable solutions for the testers.

Other cities in Europe

• The city of Ghent is building on Tim Berners Lee's new project, Solid, which aims to give users back the power over their data. With the support of the startup Inrupt, founded by Tim Berners Lee, users will be able to create their own PODS (personal online data stores), allowing them to keep control of their data.
• The European DECODE project has launched pilots in Barcelona and Amsterdam. The first city has focused on Digital Democracy (Decidim Platform) and Citizen Science Data Governance (citizen sensor systems).
• The City of London is working with the Open Data Institute and the Sharing Cities project to develop the Data Trust.
• The city of Trento, Italy, is experimenting with the My Data Store tool, designed by the Mobile Territorial Lab (Telecom Italia) through a variety of experiments.
