The most important shortcomings of solutions based on public key infrastructure and digital signatures are: costs, ambiguous laws, and nuisance of daily use.
The purpose of this article is to discuss the motivation and benefits, as well as a presentation of concepts, high-level architecture, and demonstration of the operation of bioPKI; i.e., a server-side encryption and digital signature platform with biometric authorization. The usefulness of even the most advanced platform of any type is negligible if convenient and easy-to-implement mechanisms are not provided to integrate this solution with external systems and applications. Thus, the possibility of integrating the bioPKI platform with applications and systems supporting PKCS#11 or CryptoAPI CSP is discussed.
