| Abstract(in English) | In this paper, a private scalar product comparison protocol is sudied. When private vectors x_1,x_2 and a private vector y is distributed among two parties, the private scalar product protocl compares the magnitude of x_1・y and x_2・y privately without revealing any information regarding privte vectors. The security of proposed protocol is shown following the simulation paradigm. As applications of private scalar comparison, we show the protocl to solve private linear discriminant problem and private Euclid distance comparison problem. |
