The problem BlockFace solves

Problem we solve -
Metamask which relies heavily on the security of the user's computer and browser which is a threat in itself.
If a user's computer or browser is compromised, an attacker may be able to access the user's Metamask wallet and steal their funds.Additionally, if a user accidentally visits a phishing site or downloads malware, they may inadvertently give an attacker access to their Metamask wallet.
Blockface aims to eliminate this problem.

Challenges we ran into

1. Improving the accuracy of the model to achieve accurate results. Facial recognition algorithms can sometimes produce false positives or false negatives, which can lead to incorrect identification or exclusion of individuals which can be problematic security applications .
2. Compatibility issues while connecting smart contract .
3. Storing face decryptor on filecoin, faced some api issues .
4. An error was encountered during the authentication process when multiple faces were detected. However, this issue was eventually resolved .
