Methods and systems for multi-party sorting of private values

摘要

Disclosed embodiments include a computer-implemented first method for providing the blinded result of a subtraction of a first split value of a first system (500) from a second split value of the first system (500) for a comparison. Furthermore, a computer-implemented second method is disclosed for computing a comparison of the blinded result of the subtraction provided by the first system (500) with a result of a subtraction of a blinded first split value of a second system (600) from a blinded second split value of the second system (600). Computer-implemented further methods for providing a contribution to the comparison of the split values are disclosed. The further methods involve a third system (700) and a fourth system (800).
