Abstract: A method for applying pairwise differential privacy to variables in a data set is disclosed. The method includes designating a random instance seed value to a first data set variable in an original data set and designating the random instance seed value to at least one additional data set variable in the original data set if a high degree of correlation is identified between the first data set variable and the at least one additional data set variable. The method further includes determining an adaptive sensitivity parameter corresponding to the first data set variable and utilizing, by a noise generation manager, two or more among the first data set variable, the random instance seed value, and/or the adaptive sensitivity parameter to generate and apply additive noise to the first data set variable to produce a pseudonymized variable for inclusion in a pseudonymized data set associated with the original data set.

Abstract: The invention provides an input device of an electric apparatus and a method of manufacturing an input device, wherein the input device comprises: a key member for receiving an input from a user, the key member comprising a plurality of circumferentially arranged touch-sensitive sensor segments and having at least one degree of freedom with respect to the body of the electric apparatus; and a feedback unit coupled to the key member and configured to generate feedback to the key member in the direction of the at least one degree of freedom as a response to the input.
