TALER with journalists for journalists

This Thursday 28 March 2024 I’ll be with radio journalists and students in Nantes, France. As part of the Festival des Libertés Numériques 2024 (Digital Freedom Fest).
It will also be an opportunity to discuss TALER, privacy rights, data protection, investigation and reportage.
I’ll share a round-up of the discussions below after the event.

Journalism, investigation and reportage must be based on the need to preserve privacy, including day-to-day personal and business payments.

It’s also an opportune moment to ask where in your workflow a privacy-preserving payment model could be implemented.

And where do you see a potential use for TALER in the day-to-day details of professional life to protect sources of information?


Hi XavCC : if selected by NGI Taler’s Open Call, the project Aipress24 will implement GNU Taler system into our journalist-centric B2B platform for players of information and innovation. Supported by the Strategic Fund for Press Development [Fonds stratégique pour le développement de la presse (FSDP)] of the French Ministry of Culture, the French Federation of News Agencies [Fédération française des agences de presse (FFAP)], the French national cluster of Open Source companies [Conseil national du logiciel libre (CNLL)], and the Technology University of Compiègne [Université technologique de Compiègne (UTC)], Aipress24 would use GNU Taler privacy-preserving functionnalities for purchasing the consultation of news. But, as a B2B platform, this privacy is no use for other products and se’rvices. On the other hand, we’re interested by GNU Taler as an alternative payument system and internal payment system in ordfer to write a new equation of how to finance the factory of information and innovation. Hope it may be useful for your reflexions.

The pricacy-preserving use of Taler will concern
1- the purchasing of consultation of news : this helps employees consult the news they want, not necessarely what their employer would like them to consult. This will be a massive use.
2- the gift of news consultation to members : same idea but you can also develop your influence or share some knowledge with members.
3- the publication of some announcements on the marketplace . For example: selling or transmitting a company.

Concerning the others product and services, we’d like to use Taler as an alternative payment service that is respectful of taxes regulations.

Several profiles were represented at this meeting in Nantes.

  • Students, who are not university or journalism school students. They are disadvantaged people apprenticed by 1 professional radio journalist.
  • Radio journalists
  • Activists from Café Vie Privée / Crypto party
  • Librarians

The thing that came up most often about TALER was its potential use in their day-to-day working lives,
the urgent need (sic) to leave fewer traces, especially for small payments, because some of them are under the eye of police or intelligence services, and also under the harmful attention of extreme right-wing groups or some of them are facing other troubles and threats. Yes, that’s the current state of affairs and daily life in France for many people.

There is a habit acquired by disadvantaged people in their daily lives and experience: to be wary of a technical solution designed and proposed by individuals/groups/organisations that seem to them to be more privileged and dominant.

Also, the hyper-technical dimension they see in TALER, and the extent of their knowledge, make them feel a certain distrust when it comes to delegating trust to a “dark box”. We could discuss why TALER and why not other technical devices. Let’s leave that aside for the moment.

The “students” in the room use their smartphones a lot, and their 3-month apprenticeship in radio journalism and investigative reporting was largely smartphone-based. At the same time, the questions were very similar for all profiles of people

I then suggested we “lift the hood” and we did a 45-minute introduction to digital hygiene through investigation together, as follows (very briefly):

  • Installing TALER via F-droid on an Android 9 device dedicated solely to testing
    • Static analysis / reverse engineering
      • Using Exodus Privacy to display the permissions and trackers of the TALER application.
      • Use of ClassyShark3xodus to display the TALER application manifest and go further in the discovery with verbosity of the results (and be able to send the information to a trusted person with skills).
    • With a computer on TALER app:
      • exodus-standalone: εxodus CLI client for local APK (file format used by the Android operating system) static analysis
      • apkcli: Command line tool gathering information on APKs based on androguard.

(If anyone here in TALER ICH is interested in finding out more about this technical point and workshop, I suggest opening a dedicated post and topic in the forum. Let me know)

It was also a matter of demystifying our relationship with technology.
There was no more time or energy to carry out a dynamic analysis (mitmproxy + PyRogue).

In the end,
although TALER remains something of a UFO for all of them, there is a definite interest in it. I have to admit that this has a lot to do with the ‘café’/workshop set-up and the close relationship we’ve maintained.
I also know that investigations journalists are also interested in what they are just discovering with TALER.

This meeting enabled us to start a small local community of interest, to receive feedback (which I think is priceless), and to open up new areas for discussion and work. The question of “Digital Identity” on a European scale was the closing theme of the session. It was posed by people other than myself who were present, rather as an overture to clearly address this problem.


Bravo ! Cool. Keep on going !
