In this paper we propose a general biometric cryptosystem framework inspired by the code-offset sketch. Specifically, the properties of digital modulation and turbo codes with soft-decoding are exploited to design a template protection system able to guarantee high performance in terms of both verification rates and security, also when dealing with biometrics characterized by a high intra-class variability. The effectiveness of the presented approach is evaluated by its application as case study to on-line signature recognition.
