"Amazon may be experimenting with a seller verification program in which people record video of their faces to create accounts and sell goods"

Buzzfeed:

The seller, who asked to remain anonymous out of fear of retaliation from Amazon, told BuzzFeed News he was not given an option to decline to submit a video of his face

...

Amazon declined to explain why or when it began asking some sellers for video proof of identity, in what regions it requests that proof, and what it does with the videos it records. The Seattle-based tech giant also would not say if the videos are processed by its Rekognition facial recognition technology, if a seller can remove video proof of identity from Amazon’s servers, and whether it has updated its seller agreements and privacy policies to address the collection and storage of biometric data.
