Abstract

Real-time online communication technology has become increasingly important in modern business applications. It allows people to easily connect with business partners over the Internet through the camera lens on digital devices. However, despite the fact that users can identify and confirm the identity of the person in front of the camera, they cannot verify the authenticity of messages between communication partners. It is because the tunnel for the video is not the same as the tunnel that delivers the messages. To protect confidential messages, it is essential to establish a secure communication channel between users. This paper proposes a biometrics-based RSA cryptosystem to secure real-time communication in business. The idea put forward is to generate a cryptographic public key based on a user’s biometric information without using Public Key Infrastructure (PKI) and establish a secured channel in a public network. In such a way, the key must be verified with the user’s biometrics online. Since the key is derived from the user’s biometrics, it is strongly user-dependent and works well to convince others of the authenticity of the owner. Additionally, the derived biometric key is self-certified with the user’s biometrics, which means the cost of certificate storage, delivery and revocation can be significantly reduced.
