Abstract
A method and apparatus for user information processing in a network environment. The method performs an orthogonal transform on first and second vectors representing information related to first and second users respectively to obtain first and second transformed vectors. Then, the method splits the first and second transformed vectors into two parts respectively, such that first and second vectors cannot be derived from the first or second parts. The first and second user devices exchange the first part of the first transformed vector and the second part of the second transformed vector. The first and second user devices calculate the inner product of the first parts and the second parts respectively. Finally, the two inner products of the parts are summed to get an inner product of the first and second vectors. Also provided are a method and system for resource recommendation in a network environment.
