Proposta de um sistema para controle de acesso seguro e inteligente de baixo custo

Abstract

The constant technological evolution makes possible the application of science to the most diverse elements of everyday life, being security and convenience the most benefited areas. Thus, this work proposes the development of a system that guarantees secure, smart access, and simplified access management to the laboratories of the Federal University of Pampa. This study became possible through the development and union of hardware and software. The ESP8266 microcontroller is used as the main processor, which has to enable the creation of numerous intelligent devices, given the ability to connect to the internet in a native and simple way. As a support structure for the electronic circuit, there is a server with a PHP API, accessed only through HTTPS requests and authentication, in order to maintain secure control. In order to store the system information, we opted for a MySQL database, which, in addition to being responsible for the data, also maintains several functions and procedures in order to resolve any possible failure or SQL injection. In addition to these, to avoid compromising the system, a web application in which management functions based on login access was developed. With the development of this complete system, it was possible to obtain a technological alternative with the potential for scalability, able to be implemented on a large scale in environments with high traffic and restricted access. Key-words: Internet of things. Security. Access control.
