Analysis of spectral opportunity in the UHF terrestrial TV frequency band
Ferreira, Melvyn; Helberg, Albert (SATNAC, 2014)In this paper an analysis to quantify the Spectral Opportunity (SO) or so-called TV white space that can be made available to White Space Devices (WSDs) as Secondary Users (SUs) of the Ultra High Frequency (UHF) terrestrial ... -
An approach to improve the match-on-card fingerprint authentication system security
Nair, Kishor Krishnan; Helberg, Albert; Van der Merwe, Johannes (IEEE, 2016)The combination of smart cards and biometrics results in a strong 2-factor authentication. It facilitates a trusted credential for authenticating an individual's identity through one-to-one biometric verification using the ... -
Fingerprint matching on smart card: a review
Baruni, Kedimotse; Helberg, Albert; Nair, Kishor (IEEE, 2017)Fingerprint Match-on-Card (MoC) offers the highest degree of privacy and security to cardholders as the fingerprint never leaves the secure environment of a smart card. The level of security of a biometric system is evaluated ... -
