  Advances in image processing and analysis as well as machine learning
techniques have contributed to the use of biometric recognition systems in
daily people tasks. These tasks range from simple access to mobile devices to
tagging friends in photos shared on social networks and complex financial
operations on self-service devices for banking transactions. In China, the use
of these systems goes beyond personal use becoming a country's government
policy with the objective of monitoring the behavior of its population. On July
05th 2021, the Brazilian government announced acquisition of a biometric
recognition system to be used nationwide. In the opposite direction to China,
Europe and some American cities have already started the discussion about the
legality of using biometric systems in public places, even banning this
practice in their territory. In order to open a deeper discussion about the
risks and legality of using these systems, this work exposes the
vulnerabilities of biometric recognition systems, focusing its efforts on the
face modality. Furthermore, it shows how it is possible to fool a biometric
system through a well-known presentation attack approach in the literature
called morphing. Finally, a list of ten concerns was created to start the
discussion about the security of citizen data and data privacy law in the Age
of Artificial Intelligence (AI).
