Abstract
A system and method of validating and performing operations on homomorphically encrypted data are described herein. The methods include processing a secure financial transaction by receiving a transaction request to complete a financial transaction, with at least a portion of the request encrypted according to a homomorphic encryption scheme, and the transaction request comprising confidential cardholder data including an account number, non-confidential cardholder data, and transaction data, and retrieving one or more sets of encrypted comparison cardholder data encrypted according to a homomorphic encryption scheme. The confidential cardholder data is then compared to each set of the comparison cardholder data using one or more homomorphic operations to determine which set of comparison cardholder data matches the confidential cardholder data and validating the confidential cardholder data. An encrypted indicator is generated indicating authorization or rejection of the request and forwarded to a party seeking authorization to complete the financial transaction.
