I've always wanted to do something similar at scale. Generate all possible random mobile numbers 11^10, check if they have a WhatsApp profile pic and run it through AWS' rekognition celebrity model (https://docs.aws.amazon.com/rekognition/latest/dg/celebritie...). You could identify the personal numbers for a _lot_ of VIPs, politicians, etc.

"Amazon Rekognition can recognize thousands of celebrities in a wide range of categories, such as entertainment and media, sports, business, and politics. With Amazon Rekognition, you can recognize celebrities in images and in stored videos. You can also get additional information for recognized celebrities."

Wow, that's legal ? :P Not to mention moral...

I guess an argument could be made how celebrities are public figures which in some jurisdictions gives them a bit worse privacy protections.

Also interesting: The article "Celebrity recognition compared to face search" [0] does actually have a disclaimer:

> Celebrity recognition should not be used in a manner that could result in a negative impact on civil liberties.

Only to then follow up how face search allows for the very same thing with your own face collections, so it's apparently not just reserved to celebrities.
