| titleOfInvention | METHOD AND FIRST COMPUTER. |
| abstract | METHOD AND FIRST COMPUTER. A method and system for performing a calculation for a scalar privacy preservation product is provided. A first part and a second part (for example, a first computer and a second computer) having a first vector and a second vector, respectively, can simultaneously determine the scalar product of the two vectors, without revealing any of the vectors to the other part. Each vector can be masked and then encrypted using a public key from an asymmetric key pair. Using homomorphic encryption operations, the scalar product of the vectors can be determined while the vectors are still encrypted. Each party can compare the scalar product or a value derived from the scalar product against a predetermined limit. As an example, two parties can make the scalar product to compare two biometric models expressed as vectors without revealing the biometric models to each other, preserving the privacy of the people corresponding to this biometric data. |
