Abstract:
In computer-implemented technology for comparing first and second values that are encrypted according to a fully homomorphic encryption scheme, the following function is computed: f ( ɛ ( x ) , ɛ ( y ) ) = { ɛ ( 0 ) … if … x ≠ y ɛ ( 1 ) … if … x = y } where ε(.) is a fully homomorphic encryption scheme.
