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.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
