Inspired by a previous attempt at creating a True Random Number Generator based on pixel fluctuations of the mobile phone camera by Andika Wasisto I implemented a Rust library with FFI bindings that uses a different approach with higher bandwidth entropy outcome based on an IEEE Southeastcon research paper.
It has been successfully tested on several mobile phones and will be implemented into the Randonautica app in the near future to provide a high quality on-device randomness source.
