New feature suggestion: add a face-blurring tool to Tella app

I have been receiving numerous requests from at-risk activists around the world specifically in the context of documenting protests under hostile regimes for a secure face-blurring tool for both photos and videos.

At the moment it seems there aren't too many easy-to-use FOSS options which digital security trainers feel comfortable to suggest aside from the Signal's face-blurring tool. Other existing options are not available for recent devices/software such as the Guardian Project's Obscura Cam .

Like many other digital security trainers I highly recommend Tella for documenting human rights violations and collecting data including in the context of documenting protests, I think this feature definitely fits the scope of the Tella app and would be really useful for its community of users to securely share the photos and videos documented.

Please let me know if this is feasible.

Thank you so much.

The issue names no files, tests, or entry points. Start by scoping secure face blurring for both photos and videos in the Tella Android app, then determine the privacy and usability requirements; done would mean an agreed, feasible feature definition for both media types.
