End-to-End Encryption Based Biometric SaaS: Using Raspberry Pi as a Remote Authentication Node

End-to-End Encryption Based Biometric SaaS: Using Raspberry Pi as a Remote Authentication Node Biometric systems are an integral part of physical access control systems. Biometric systems ensure that an opportunity to use a system or service is done by a valid user. These systems are used in various applications like ATMs, voting system, aadhar card, attendance management system etc. The biometric systems are in operation for a quite long time and their use is increasing. There is a need for low cost, scalable systems with high availability. In this paper a cloud based biometric system architecture is proposed, to make the system efficient and economical for remote enrollment. Authentication node is implemented on a Raspberry Pi, which is a low cost computer running on Linux. The system is capable of capturing multimodal biometric traits such as face and fingerprints and send them to cloud service by end-to-end encryption process. The proposed architecture is leveraging the power of cloud to make the system scalable and pluggable. Thus the use of Raspberry Pi makes the biometric system low cost and portable.
