Abstract— 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.
