Abstract:
A two-party approximation protocol is transformed into a private approximation protocol. A first input xε{0, 1, . . . , M}n and a second input yε{0, 1, . . . , M}n of a two party approximation protocol approximating a function of a form ƒ(x, y)=Σj=1ng (xj, yj) is received. Variable B is set as a public upper bound on ƒ(x, y). Variable l is set l=O*(1). The following is performed until ∑ j = 1 l z j ≥ l t or B
