A method for detecting irregular inputs for data processing applications, wherein the method comprises the followings steps: a) capturing an input signal sequence in a data processing application from at least one physical and/or virtual input unit and determining at least two time durations tS for a duration of capturing an input signal and at least two time durations tP for the duration until the capturing of a next input signal, b) forming a first vector with or based on the determined time durations tS and forming a second vector with or based on the determined time durations tP, wherein a length of the first and the second vector is predetermined and the elements of the first and the second vector correspond to consecutive predetermined time intervals until a maximum capturing duration tMax; wherein the values of the elements of the first and the second vector have Boolean characteristics; wherein a fingerprint of the input is determined by converting the first and the second vector in one bit field each and by connecting the bit fields of the first and the second vector in full extent or by blurring in shortened form into a common bit field; and wherein the method further comprises the following steps: c) determining irregularities in the input signal sequence by analyzing the fingerprint, and d) providing an indicator value based on the determined irregularities. a) capturing an input signal sequence in a data processing application from at least one physical and/or virtual input unit and determining at least two time durations tS for a duration of capturing an input signal and at least two time durations tP for the duration until the capturing of a next input signal, b) forming a first vector with or based on the determined time durations tS and forming a second vector with or based on the determined time durations tP, wherein a length of the first and the second vector is predetermined and the elements of the first and the second vector correspond to consecutive predetermined time intervals until a maximum capturing duration tMax; wherein the values of the elements of the first and the second vector have Boolean characteristics; wherein a fingerprint of the input is determined by converting the first and the second vector in one bit field each and by connecting the bit fields of the first and the second vector in full extent or by blurring in shortened form into a common bit field; and wherein the method further comprises the following steps: c) determining irregularities in the input signal sequence by analyzing the fingerprint, and d) providing an indicator value based on the determined irregularities. wherein the values of the elements of the first and the second vector have Boolean characteristics; wherein a fingerprint of the input is determined by converting the first and the second vector in one bit field each and by connecting the bit fields of the first and the second vector in full extent or by blurring in shortened form into a common bit field; and wherein the method further comprises the following steps: c) determining irregularities in the input signal sequence by analyzing the fingerprint, and d) providing an indicator value based on the determined irregularities. c) determining irregularities in the input signal sequence by analyzing the fingerprint, and d) providing an indicator value based on the determined irregularities. <EOS>
