Contribution of an Embedded and Biometric System in a Replicated Database for Access Control in a Multi-Entry Institution

The present work solves the problem of automating access control to the premises in a multi-entry university institution by ruling out possible recurring problems due to falsification of receipts, pretending to be an assistant or a former student, etc. The work is based on the results of a study carried out by a team of experts in the field of access control. On the other hand, there is also the loss or forgetting of the slip for academic fees. To carry out this access control, we have used biometrics based on fingerprints stored in a distributed database that interacts with an on-board system under Arduino, which gives us the possibility of assembling the performance of the programming and the electronics. More precisely, we have programmed electronic systems for the automatic opening of doors without the action of a human being.
