OTP-Based Smart Fingerprint for Wireless Locking System Using Arduino

Abstract

The protection of private property is a top priority in today's society. A new security system that employs biometric data and a mobile number to enable access only to authorized people has been presented as a solution to this problem. Comparing this technique to more conventional approaches like using actual keys or door knobs, it offers a higher level of protection and the ability to manage access to doors. Biometric technologies are susceptible to a variety of errors and might not be appropriate for those with physical limitations. An alternative to this is a speech recognition access control system that enables users to access door systems using their mobile phones and a bluetooth connection. This system is excellent for usage in secure businesses, banks, and residences since it uses a distinct fingerprint, one-time password (OTP), and global arrangement for mobile communications (GSM) technology.
