A Cost Effective IoT-based Solution for Biometric Security Systems in Blood Banks

We have always been concerned about outsiders breaking into our homes, offices, and, in particular, hospital blood banks. Blood samples from people with uncommon blood types are stored in a blood bank. Any adjustments or modifications can possibly endanger people's lives. As a result, security is critical. The Internet of Things (loT) paradigm seeks to solve this security issue as cheaply as possible. This research proposes a low-cost fingerprint door lock system that can store 137 fingerprints at once. The loT model includes two phases: the enrolment phase, in which fingerprints are enrolled, and the verification phase, in which the person accessing the blood bank must authenticate their fingerprint. This is one of the cheapest and finest ways to safeguard blood banks against intruders, and it may be simply implemented by various government entities and non-profit groups that serve society. It has a 98% accuracy rate. The system uses lights and a buzzer to approve or disapprove people.
