Abstract: A method of anonymously matching a buyer to a seller comprises receiving, at a server from the buyer, an approval model in byte code format, encrypting, by the seller, customer data to produce encrypted customer data, executing, by the server, the approval model using the encrypted customer data as an input, generating, by the server from the executed approval model, a transaction response, determining, by the server, that the transaction response comprises an approval of at least one product, publishing, to the server by the seller, the product lead, receiving, at the server from the buyer, an acceptance of the product lead based on the approval, and sending, by the server, the customer data to the buyer in response to receiving the acceptance of the product lead. The customer data can correspond to a product lead.
