- Authors: Marta Gomez-Barrero, Javier Galbally
- Abstract summary: It is now an accepted fact that it is possible to reconstruct from an unprotected template a synthetic sample that matches the bona fide one.
This reverse engineering process constitutes a severe threat for biometric systems from two different angles.
Biometric stakeholders have produced over the last fifteen years numerous works analysing the different aspects related to inverse biometrics.

- Abstract: With the widespread use of biometric recognition, several issues related to
the privacy and security provided by this technology have been recently raised
and analysed. As a result, the early common belief among the biometrics
community of templates irreversibility has been proven wrong. It is now an
accepted fact that it is possible to reconstruct from an unprotected template a
synthetic sample that matches the bona fide one. This reverse engineering
process, commonly referred to as \textit{inverse biometrics}, constitutes a
severe threat for biometric systems from two different angles: on the one hand,
sensitive personal data (i.e., biometric data) can be derived from compromised
unprotected templates; on the other hand, other powerful attacks can be
launched building upon these reconstructed samples. Given its important
implications, biometric stakeholders have produced over the last fifteen years
numerous works analysing the different aspects related to inverse biometrics:
development of reconstruction algorithms for different characteristics;
proposal of methodologies to assess the vulnerabilities of biometric systems to
the aforementioned algorithms; development of countermeasures to reduce the
possible effects of attacks. The present article is an effort to condense all
this information in one comprehensive review of: the problem itself, the
evaluation of the problem, and the mitigation of the problem. The present
article is an effort to condense all this information in one comprehensive
review of: the problem itself, the evaluation of the problem, and the
mitigation of the problem.

sparsely-connected RNNs [61.080598804629375]
People with chronic pain unconsciously adapt specific body movements to protect themselves from injury or additional pain.
Because there is no dedicated benchmark database to analyse this correlation, we considered one of the specific circumstances that potentially influence a person's biometrics during daily activities.
We proposed a sparsely-connected recurrent neural networks (s-RNNs) ensemble with the gated recurrent unit (GRU) that incorporates multiple autoencoders.
We conducted several experiments which indicate that the proposed method outperforms the state-of-the-art approaches in classifying both pain level and pain-related behaviour.

Cancelable biometric schemes aim at generating secure biometric templates by combining user specific tokens, such as password, stored secret or salt, along with biometric data.
The security requirements of cancelable biometric schemes concern the irreversibility, unlinkability and revocability of templates, without losing in accuracy of comparison.
In this paper, we formalize these attacks for a traditional cancelable scheme with the help of integer linear programming (ILP) and quadratically constrained quadratic programming (QCQP)
