Special Issue Information

Dear Colleagues,

Biometrics is a technology used for authentication and identification purposes, determining whether a person is the same individual as one previously stored within the system through the analysis of the person’s raw data acquired through a sensor. With the recent development of sensor technology, the quality of raw data for realizing biometrics has been dramatically improved, and recognition accuracy has also been greatly improved through sensor data analysis based on deep learning. The number of biometrics applications for smart device identification, identification for fintech untact transactions, and intelligent CCTV implementation is also increasing significantly. Within this framework, we are pleased to serve as Guest Editors of this Special Issue on “Sensor-Based Biometrics Recognition and Processing”. In this Special Issue, all issues related to sensors can be addressed regarding their use for biometrics-based authentication/identification purposes. In addition to new biometrics sensors, topics such as pre-processing, (signal or image) quality enhancement, and performance improvement through multi-sensor data fusion or multi-data fusion from single sensors for human data acquired through the sensor can be considered. In addition, topics such as anti-spoofing and new databases considering various sensor variations can also be considered. New neural network models or matching methods for biometrics can also be proposed. Biometrics methods that are robust to limited information and occlusion issues in the COVID-19 pandemic are also a welcome topic.

Two important tasks in many e-commerce applications are identity verification of the user accessing the system and determining the level of rights that the user has for accessing and manipulating system’s resources. The performance of these tasks is directly dependent on the certainty of establishing the identity of the user. The main research focus of this paper is user identity verification approach based on voice recognition techniques. The paper presents research results connected to the usage of open-source speaker recognition technologies in e-commerce applications with an emphasis on evaluating the performance of the algorithms they use. Four open-source speaker recognition solutions (SPEAR, MARF, ALIZE, and HTK) have been evaluated in cases of mismatched conditions during training and recognition phases. In practice, mismatched conditions are influenced by various lengths of spoken sentences, different types of recording devices, and the usage of different languages in training and recognition phases. All tests conducted in this research were performed in laboratory conditions using the specially designed framework for multimodal biometrics. The obtained results show consistency with the findings of recent research which proves that i-vectors and solutions based on probabilistic linear discriminant analysis (PLDA) continue to be the dominant speaker recognition approaches for text-independent tasks.
