Unik blockchain-teknologi kan 'afsløre' produkters identitet og historie

Infineon har udviklet og for nyligt demonstreret en blockchain applikation, der kan 'indbygges' i alle typer af produkter, og som via NFC-teknologi kan videregive relevante oplysninger om det aktuelle produkt (in english).

By storing information in the blockchain the manufacturer can document the authenticity of the product, feature a limited edition or demonstrate the sustainability of the production like e.g. its compliance with environmental standards. Consumers in turn can access the information stored in the Blockchain via a mobile device and an app.

SECORA Blockchain can be used for a wide range of products, from fashion and footwear to electronics or healthcare. At the virtual trade fair electronica 2020, Infineon presented the functionality and use cases of the innovative solution in cooperation with the block chain company block42.

The information about manufacturer and product can be stored in the blockchain as individual data blocks that build on each other. This can allow anyone to access the decentralized data register from anywhere. Besides origin, changes to the products, use of original spare parts or changes of ownership of limited collector's items can be continuously documented.

However, it is also important here that access to the blockchain is protected to prevent data manipulation. In this way, the brand and reputation of manufacturers can be protected and the sale of counterfeits be prevented.

SECORA Blockchain combines a tiny cryptochip with a radio antenna in a flat housing with a total thickness of max. 300 µm. It can be attached barely visible behind a label or on the product itself and is hence easy to integrate. As a hardware-based solution SECORA Blockchain has a decisive advantage over other blockchain access options: It is protected against both hardware- and software-based attacks.

Another essential advantage: SECORA Blockchain can encrypt data and signatures with a private key. The product with integrated chip can thus directly and easily establish a connection to the corresponding blockchain entry with an NFC-enabled mobile device. The signature key, which authenticates the identity of the product, is not generated on the mobile device, but in the cryptochip and is securely stored therein, unlike other solutions on the market. This further increases the security of the application.

SECORA Blockchain with SPA Package is now available in volume quantities. It supports cryptoschemes like Etherium, Bitcoin, ETR ERC-20. Additionally, Infineon’s Blockchain Security2Go starter kit enables blockchain designers to quickly develop easy-to-use access solutions for blockchain applications.
