Ask HN: Could you help me to build a database?

Recently, I am doing a Deep Learning project, which related to the PRNU (which can be described as a fingerprint of the mobile camera). But we need a lots of training data (pictures and brands of devices), so I want to ask if you can help me to collect photo data.

All you need to do is installing a small app, take several photos then upload to our server. The application is totally open source, We will not collect any of your private data, you can checkout the source code. And, once the raw pictures database is established, it will be free for anybody to download.

I need your help, it only takes your very few minutes to finish, we appreciate your help, Thanks.
