Civil liability of software using biometrics on the grounds of Polish jurisdiction

- Introduction
We live in a smartphone era, almost every of the latest smartphone model includes a fingerprint reader. Some models feature facial recognition systems (such as the latest Apple iPhone 8 smartphone, that will use such system) or iris scan (for instance Samsung Galaxy S8 has that system incorporated). As you can see, the use of biometric security in the smartphone market has become a common practice. Earlier, before smartphone manufacturers began using biometrics, it was “present” at airports, state borders, or in security systems. It is already a noticeable part of our everyday life, which makes it clear that in the future biometric security will be an important part of our daily lives. The use of biometrics in computer science opens up a new sphere in the use of sensitive personal data. What is biometry? What are its types? What about the data that it holds? Who is responsible for possible system failures? Finally, what legal regulations can apply to it?
