Internet of Things and biometric data versus employee privacy in the Polish case
2020
The Internet of Things is a modern technology that affects every area of human life, includ- ing employment relationships. IoT enables the processing of specific personal data categories, including biometric data, and entails the risk of employers interfering with employee privacy. Due to the use of intelligent solutions, the issue of employee privacy, which is, in princi- ple, a personal right subject to protection, becomes significant. The relationship between an employee and an employer includes two subjects of legal protection, the meeting of which may lead to internal contradiction. There is the employee’s dignity and privacy, on the one hand, and protection of reasonable interests of …
Biometric characterisation and taxonomic considerations of european rabbit Oryctolagus cuniculus (Linnaeus 1758) in Sicily (Italy)
2014
In Sicilian Mediterranean ecosystems the European rabbit Oryctolagus cuniculus is a keystone species, very important for popular small game species and for ecological reasons. However, its spread across the island seems to have decreased and fragmented in recent times, but until now no accurate population management has been carried out due to the lack of ethological, ecological and taxonomic knowledge. A biometric analysis of European rabbit specimens from Sicily to widen current taxonomic knowledge was performed. In this paper, 7 body variables and 23 cranial variables of 166 and 120 individuals, respectively, were examined. Thereafter, the results were compared with biometric data from o…
EEG-based biometrics: effects of template ageing
2020
This chapter discusses the effects of template ageing in EEG-based biometrics. The chapter also serves as an introduction to general biometrics and its main tasks: Identification and verification. To do so, we investigate different characterisations of EEG signals and examine the difference of performance in subject identification between single session and cross-session identification experiments. In order to do this, EEG signals are characterised with common state-of-the-art features, i.e. Mel Frequency Cepstral Coefficients (MFCC), Autoregression Coefficients, and Power Spectral Density-derived features. The samples were later classified using various classifiers, including Support Vecto…
Comparison of biometric measurements using partial coherence interferometry and applanation ultrasound
2003
Abstract Purpose To compare and contrast axial length (AL) measurements assessed by ultrasound biometry and optical biometry. Setting Department of Ophthalmology, Johannes Gutenberg-University, Mainz, Germany. Methods Optical biometry and ultrasound biometry were performed in 360 eyes to measure AL. Results In eyes with a clear-appearing crystalline lens, there was a statistically significant median difference in AL measurements between the 2 methods in eyes with a normal or long length. In eyes with cataract, there was a statistically significant median difference in AL measurements in eyes with a normal or short length. In these cases, optical biometry produced larger readings than ultras…
Caratterizzazione e valorizzazione bio-agronomica di diverse accessioni di aglio in ambiente collinare siciliano
2008
L'aglio coltura "antica" e tipica di molte aree della Sicilia, ha svolto e continua a svolgere un ruolo fondamentale nella storia della tradizione culinaria. La specie viene, inoltre, utilizzata per usi terapeutici e presenta pregevoli caratteristiche nutrizionali. L'ampia disponibilità di popolazioni locali di aglio ha indotto, il Consorzio di ricerca Co.Ri.S.S.I.A. di Palermo ad avviare una ricerca finalizzata alla caratterizzazione e valorizzazione di accessioni di aglio di diversa provenienza. Dall'esperienza condotta è emerso che la specie ha presentato, in generale, una buona adattabilità all'ambiente di prova, riuscendo a fornire produzioni quanti-qualitative soddisfacenti.
Smart Wireless Sensor Networks and Biometric Authentication for Real Time Traffic Light Junctions Management
2013
The main challenge of intelligent transportation systems (ITS) is to deal with ‘real-time’ information to improve vehicular traffic management. Road data can be processed and used for dynamic traffic light management in order to reduce waiting times in queues. This paper proposes an innovative distributed architecture based on a wireless sensor network (WSN) with a network coordinator providing remote and ubiquitous authentication module for managing unexpected events. The architecture is completed by a dynamic module for street priority management depending on traffic rate. Many experimental trials have been carried out considering three different levels of traffic intensity to prove the e…
Wildflowers: opportunities for urban landscapes
2022
The concept of “sustainability” is also becoming of great interest in the management of ornamental and territorial greenery. The new trends in the design of green spaces are aimed both at enhancing their “natural” aspects and at researching schemes characterized by lower maintenance costs. Spontaneous vegetation represents a characteristic component of the urban environment and is always adequate to the conditions of the site in which it is located. In this context, the role of spontaneous herbaceous plants becomes fundamental and constitutes an effective response to the current demand for the defence, conservation and enhancement of biodiversity. So far, the use of spontaneous vegetation f…
