A method for secure data transformation and lookup is executed by a computer system. A data value to create an encrypted value is encrypted by the computer system. A hash value based on the encrypted value is generated by the computer system. A modulo operation is performed by the computer system on the hash value to create a modulo value. A transformed value from a lookup table is retrieved by the computer system by using the modulo value as an index for the look up table. The transformed value is provided by the computer system. |
