Could a Blockchain/DHT solution work for this? Normalize and hash the data and send it to the network to check its karma. If there's no karma then it's a new customer, otherwise the karma tells if it's a good/bad customer. Then after they buy you add or reduce a karma point.
Would there be a way for someone to reverse/bruteforce the hashes to figure out people information?
