Proof of Presence based on Blockchain Technology

In different areas such as the financial field, supply chain management, and healthcare are moving to a new technology to manage their own business in a secured and decentralized way by using the blockchain. Basically, it is a particular type of distributed ledger technology which is a protocol that allows the transactions to be distributed and validated among peers in a synchronized way and to be recorded. Once these transactions are recorded, they cannot be changed or spoofed. Due to these features, blockchain is being used in the validation and proofing of presence of an object. Proof of presence means to know whether a person or an object was in a certain time at a certain position. For example, we hear a lot of people are trying to make a bad review for an hotel or a restaurant and basically; they have not been there, for the manager to be sure of these reviewers whether they were really in the hotel or not, they basically need to proof their presence. Relying on GPS for tracking online shopping is not a good idea since the GPS can be jammed, spoofed, and hacked due to several factors. So, the blockchain helps in solving these problems by validating the presence of a person or an object. In this thesis we will deal with the Hyperledger fabric blockchain in proofing the presence of vehicles in a pre-defined area.
