Teklia has developed a tool to validate if a website user is a human or a bot (like the famous reCaptcha service from Google).
If you want to use Ocapi, contact us!
We currently support 3 types of challenges:
- a user must write down 2 words or numbers after reading them from 2 images (transcriptions challenge)
- a user must select all the images described by a word (classification challenge)
- a user must write down one or more words after listening to an audio sample (audio fallback for people with low-vision)
You can try out the challenges on our demonstration page!
The original idea was developed in 2018 during a hackathon at the Archives Nationales, under the name CaptchAN, and described in this blog post. The project was then awarded by the Ministère de la Culture in 2019 as a cultural innovative service project. The partners were the Archives Nationales, the Bibliothèque Nationale de France, the Musée de Bretagne and Decalog. Read this post on the project 2 years after its start.
