Bio-metric recognition and new patterns of behavioral data collection

Since some time on we have been hearing about bio-metric recognition and this technology has already been adopted in some airports to speed up transit procedures for passengers. In fact Bio-metric data are personal data because allow identity verification.

Bio-metric devices are actually very popular and are widespread in smartphones to enable the Face Unlock
Bio-metric characteristics can be biological but also behavioral and can lead to identification by performing the comparison one by one.
For example, fingerprints are bio-metric trait and allow identification in the comparison one by one and allow exclusion by making the comparison one by many.
Another example of bio-metric trait is the voice. The voice is the result of physical and anatomical characteristics that determine its qualities.
The most widely treated bio-metric trait is surely the face and requires necessarily the acquisition of an image. There are a varied selection of bio-metric sensors and different methods of data acquisition, however the purpose is common and it is to the elaboration of a mathematical representation (bio-metric model).
