Template protection is an issue of paramount importance in the design of biometric recognition systems. In this paper we present a biometric cryptosystem applied to iris biometrics, where template security is guaranteed by means of a framework inspired by the digital modulation paradigm. Specifically, the properties of modulation constellations and turbo codes with soft-decoding are exploited to design...
In this paper a secure Incremental Redundancy - Hybrid Automatic Repeat Request (IR-HARQ) scheme, based on Turbo Codes (TC), is proposed. Typical drawbacks of HARQ systems, such as spectral efficiency, latency unpredictability, correct packet delivery control (under fixed dead-line time) are definitively minimized thanks to a mathematical approach that exploits the statistical property of Additive...
Providing protection to the transmission of digital multimedia contents is nowadays an important requisite for many applications. However, it can also represent a great challenge, especially when dealing with wireless channels where, apart from preventing illegal data access, it would desiderable to possess the ability of discriminating between malicious data modifications and data distortions due...
