FAKE PRODUCT IDENTIFICATION USING BLOCKCHAIN TECHNOLOGY

ABSTRACT:-

            Nowdays, Blockchain technology has a great demand in today’s market. It gained a lot of interest over the past few years. Blockchain technology explored itself  very rapidly in the financial industry. Blockchain does not have any trusted intermediary. The attention toward blockchain technology is increasing and it develops various applications in an easy way. It is known for faster transactions and adding more transparency. It is used in financial transactional records. Therefore  the contents of its data are tamper-proof before it is used in blockchain. The customer thinks a thousand times before purchasing the product. He has questions in his mind whether the product that he is purchasing is fake or not. So in order to stop the making of fake products ,it is important to bring transparency about the products to the notice of the consumers. The developing presence of fake and risky products in the world is a purpose for the situation and blockchain technology has taken the following step toward its entire demolition. This technique is used to watch the supply chain in the market. So In this paper , we create a system that delivers the original product to the customer and helps to identify if the product is fake or real to the customer. This proposed system not only stops the making of fake products but also spreads awareness about this. For the creation and packaging of the right items each of these items needs to be provided with a digital code of its own. This research paper proposes a form of identification of fake products using blockchain technology. Discusses the software implementation process where the product code is scanned using this application and confirms whether the given product is fake or not.

OBJECTIVES OF THE PROJECT:-

The main objectives of this system are:

• To Design an Anti Counterfeit System using Blockchain.
• To secure product details using a QR code.
• Provide security to the clients by offering data to clients.
• The immutable characteristic of the blockchain provides more security and transparency in the transactions of the proposed system.
• To stop the making of fake products by conducting transparency about the products to the notice of the consumers.
• To become aware of fake products from the primary product available in the marketplace and to enhance this performance.

EXISTING SYSTEM:-

In Existing system, ‘A Comparison Survey Study on RFID Based Anti-Counterfeiting Systems’ describes a frequency identification tag for the detection of fraud products that has been considered over the last few years. In this system we represent a review based on a test topic for duplicate items using Radio Frequency Identification tags in products. In this system, Radio frequency identification (RFID) and remote sensor networks are most used for remote development and It offers a number of possibilities for future while RFID tags like an actuator require a control signal and a power source. RFID detects areas and physical evidence of labeled objects – but unlike using laser light from verified tags, it uses low-frequency radio waves to collect and store data. In a cell or distribution center, this system is used to make the assortment of information automated. The transceiver scans the radio waves and sends them to the RFID tag. Separate data is then transferred from a small microchip tagged to the RFID reader.           

PROPOSED SYSTEM:-

As most people shop from remote places, there is the possibility of getting Counterfeit or fake products. This fake product affects the customer as well as company name. They have to face major loss from this situation. There is no right solution before dealing with this problem. As easily copied barcodes there is no guarantee system, or a good solution to distinguish counterfeit products from real products. Blockchain is the most promising technology emerging in recent years that can help to solve that type of problem. Blockchain Technology can be used to monitor and keep track of shipped products so that users only get the right product. The main purpose of the project was to bring transparency about the product during customer purchasing and help customers to see if the product they are buying is original or counterfeit easily. 

In this proposed system, we do Fake product Identification Using Blockchain Technology. The first step is to bring all the manufacturers to the blockchain network and collect their major product information. Product verification is done by registering and providing them with the correct id and password. The manufacturer will be the main owner of the item. The manufacturer will ask the manager to add the product to the network while the QR code will be assigned to that product. The regulator will register the product and the manufacturer on the network if the applicant is the actual manufacturer. Once the product is recorded on the network it will create a smart contract with the unique QR code of the product where the product details are stated in the encrypted text form. To protect the QR code from copying there is a Copy Sensitive digital image in the QR code. In the next step the manufacturer will send the product to the distributor and the status is set as shipping; it will not change the ownership of the product until a request from both parties for the purchase and sale of the product is approved. As soon as both parties agree to a joint venture, its ownership in the blockchain network will be transferred in the form of a smart contract automatically after payment has been made. At this stage clients will be provided with the Android app and consumers can scan the QR code assigned to the object using the Android app. The scanner scans the product and removes the encrypted text in the algorithm provided and receives information about the current manufacturer and owner of the product and can decide whether to purchase the item or not.

MODULES:

• Type of Logins: Three Type of login. Manufacturer, User and Admin.
• Registration: User have to register to become a part of project.
• Login: User have to login themself to access in project.
• Add Product : After Manufacturer Login Manufacturer can add product using java script and smart Contract in Block chain Database.
• Generate Qr Code: All Product data display in admin side and admin verify that product and generate qr code of that related product using python and add in block chain database.
• Scan Qr Code: User Scan that QR code using Android Application And then Display All information of product in our mobile screen.

ADVANTAGES OF PROPOSED SYSTEM:

• The information used for this proposed system is obtained by distributed computers throughout the world. All distributed computers show their computational power to make information secure and immutable.
• Using functions and power allocations, the entire blockchain system uses authentication, delivery, and data management on the local side. Blockchain technology is not dependent on additional external controls, has no internal controls, and is independent.
• The move to the blockchain is completely transferable and straightforward. Anyone can come to them from anywhere in the world. 
• We use cryptography algorithms to add a special identifier of the individual information in the blockchain  and we implant such identifiers in the Blockchains. 
• It is not possible to reproduce the substance from any identifier since we utilize single-direction cryptographic functions(hashes).
• Blockchain facilitates faster transactions by allowing P2P cross-border transfers with digital currency.
