Interoperability of Digitizers

Dynamic signature verification is a subset of that larger science that includes fingerprint recognition, hand geometry, and voice recognition. Signature verification is primarily behavioral in nature like voice recognition, but has some very unique traits which make it harder to test and evaluate. These challenges include the fact that a signature is learnt, it contains variant measures, it can be changed by the owner of the signature, and that a signer might have several versions of the signature, depending on the intent of the signer. There are a number of digitizers on the market, and making sure that they interoperate is key in developing a DSV solution. This research will examine which variables are interoperable across a number of digitizers. In conjunction with the work done in SC37, a study is underway which examines the “force” variable to understand whether digitizers on the market are calibrated correctly.
