Since Clears doesn’t keep any personal information about its users in an online database, there is no data to steal, resell or tamper with.
Each KYC is encrypted and hosted by Clears. No data is shared with/by anyone. We certify that the KYC has been completed and we act as an escrow for personal data between the user and the company doing the KYC. A hash of the data is stored daily in the blockchain to ensure data integrity.
Data hashes for users can be securely stored inside the blockchain since there is no possibility of decryption because the data stored in the hash is not actual data, but a representation of data. When we hash the data we also encrypt it before. That way, even for small strings of data, brute force attacks are useless.
