Business representatives have also noticed the opportunity to use biometric data. Currently, this solution is the most common used in the banking sector. Biometry can be used in this sector to secure access to mobile applications, accounts in transaction services or for the identification of customers using their helplines, and while creating bank accounts on the Internet.
Behavioral biometry constitutes an addition to the traditional biometry. Behavioral data can be used to supplement biometric features by adding the behavioural data of a specific person, which are not their biological features. Handwriting or the power that they press the screen of a smartphone may constitute as examples of behavioral data.
The most significant benefit of employing biometric data in securing our personal data or our money on the Internet is, in general, the difficulty of such data being used by third parties. The combination of traditional biometric data and behavioral biometry allows for the creation of a complex, unique pattern that provides a robust defence against fraud.

They cannot be used freely, and you should consider not only the provisions of GDPR, but also the data minimisation rule. The use of such data should always requires a decision to be made on the balance between the goals of the business and the rights and freedoms of the data subjects.
