摘要
A privacy-preserving scalar product calculation system is provided. A first unit linearly transforms an n-dimensional vector Va into an n-dimensional vector based on a scalar value based on a random number Wi and a random number Rj to calculate a remainder by dividing each element of the linearly transformed n-dimensional vector by a random number Mi, and transmits an n-dimensional converted vector X including each of the remainders as its element to the second unit, the second unit calculates an inner product value Z based on the received n-dimensional converted vector X and an n-dimensional vector Vb, and transmits the inner product value Z to the first unit, and the first unit further calculates, based on a reciprocal of the scalar value and the receive inner product value, a scalar value and which calculates a remainder by dividing the scalar value by the random number Mi.
