BiosecurID: a multimodal biometric database

A new multimodal biometric database, acquired in the framework of the BiosecurID project funded by the Spanish MEC, is presented together with a brief description of the acquisition setup and protocol. The database includes 7 unimodal biometric traits, namely: speech, iris, face (photographs and talking faces), signature and handwriting (online and off-line), fingerprints (acquired with two different sensors), hand (palmprint and contour-geometry) and keystroking. The database comprises 400 subjects and presents features such as: realistic acquisition scenario, balanced gender and population distributions, availability of information about particular demographic groups (age, gender, handedness), acquisition of skilled forgeries, and compatibility with other existing databases. All these characteristics make it very useful in research and development of multimodal biometric systems
