ABSTRACT

As technology continues to be widely adopted and used, data slowly becomes more centralised and stored in servers owned by large companies. This opens up issues on security and the central point of failure for technology , such as IoT devices, that rely on these servers for access. The purpose of this study is to develop a decentralised authentication protocol system for IoT devices as an alternative to the traditional system for accessing IoT devices. The IoT devices that will be used are the ESP-8266 module and the sensors. Using blockchain technology, the researchers will then use smart contracts as the alternative authentication protocol. The researchers will develop and test both Centralised Authentication System and Decentralised Authentication System in the University of San Carlos - Talamban Campus Laboratory and compare the findings. With this system, the user can access their IoT devices from decentralised servers and the authentication details of the connection are securely stored in the blockchain which will avoid malicious people from accessing your IoT devices without his/her permission.

ABSTRACT

Finishing operations represent a crucial stage in manufacturing, where it is necessary either to remove unwanted material from a part, or provide aspect features to it. This includes smoothing, polishing and machining-alike solutions. In this paper, a new methodology to approach the automation of finishing processes in manufacturing, is presented. Four main steps are defined: part measuring, path creation, finishing operation, and part verification. Two use cases, belonging to real workplaces in an automotive factory of the Stellantis group, are presented as validation scenarios. One of these, a cyber-physical system to deburr a weld beam between two parts of complex geometry, has been successfully working in-line for the last ten years. This represents an improvement of the ergonomics of the operators and their working conditions, and a reduction of costs, showing that the automation of finishing process means an opportunity to increase productivity, quality and efficiency in the factory.
