Usage of fuzzy extractors in a handwritten-signature based technology of protecting a hybrid document management system

The paper covers the issue of protecting private keys of a digital signature in a hybrid document management system. It proposes a method of generating private keys based on a handwritten signature using a method of building a reference signature description. The method demonstrates the following indicators of reliability: FRR=0.148, FAR=0.05 when the length of the key is 304 bits.
