Online signature verification by continuous wavelet transformation of speed signals

作者:

Highlights:

• We proposed a novel online signature validation system using signature frequencies.

• A hidden subsystem extracts the displacement data disregarding the signature shape.

• Speed signal is extracted from the data to be transformed by CWT and trained by SVM.

• EER of 3.41% with 1.67% FNR and 3.33% FPR are achieved for 120 trials.

• Similar results are achieved by the samples taken from SVC2004 and SUSIG datasets.
