Device for detecting partial matches between a first time varying signal and a second time varying signal, the device including: a fingerprint extraction stage; and a matching stage, wherein each feature information of a first fingerprint is pairwise compared with each feature information of a second fingerprint; wherein the matching stage includes a similarity calculator stage; wherein the matching stage includes a matrix calculator stage configured for arranging similarity values in a similarity matrix having dimensions of L×L, wherein an entry in the i-th row and j-th column of the similarity matrix is the similarity value calculated from the pair of the i-th feature information of the first fingerprint and of the j-th feature information of the second fingerprint; wherein the matching stage includes a detection stage configured for detecting the partial matches by evaluating a plurality of diagonals of the similarity matrix.
