Any cryptographers out there willing to do some cryptanalysis on my data protection?

Here's a link to the README.md that has the high level design.

Are there weaknesses in the scheme? For example, if the user got enough data after one bad guess to brute-force guesses on their own afterwards, the scheme would be useless. It defends vs that attack by hashing the user ID, device ID, and pin to a point on the curve before blinding the point and sending it to the distributed pseudo-random function servers.

It?s best to start by sharing only non-sensitive, sample data or algorithm details with experienced cryptographers or cybersecurity professionals. They can review your encryption methods, key management, and potential vulnerabilities. For reliable insights, you can also post your request on specialized security forums or platforms like Stack Exchange?s Cryptography section, where experts can safely evaluate your system.
