Device Distributed Blockchain - 2DB

Resumen de: US20260095307A1

0000 This invention relates to an improved method and system for authenticating the travel path of an object using a distributed asynchronous system incorporating blockchain technology and encrypted codes. The system utilizes digitally secured tags containing encrypted logistical data. These tags are physically and digitally associated with the product prior to entering the supply chain. Gateways equipped with artificial intelligence are strategically placed throughout the transportation route, each gateway receiving inputs from any number and type of sensors placed throughout the gateway's physical location. These gateways continuously collect data from their environment and utilize artificial intelligence to create dynamic environmental profiles. These profiles, encapsulated within a cryptographic key, are immutably recorded onto the blockchain ledger associated with the tag device physically associated to a shipment. The distinctive feature of this innovation assures an unalterable record of each shipment's journey, enhancing security, promoting transparency, and enabling swift transmission—and verification—of shipment data.

NCHAIN LICENSING AG [CH]
nChain Licensing AG

Resumen de: EP4718768A2

A public key may be recorded on the blockchain by a certificate authority in such a manner that any third party may quickly and easily verify that the public key is certified by the certificate authority and that the certification has not been revoked. The certificate authority may be able to revoke the certification nearly instantaneously, and/or may be able to simultaneously certify a new key for the same entity while revoking the old key. The verification may be incorporated into a new transaction so that there is no gap between reliance on the certificate and the verification of its validity. In some cases, each transaction in which the certificate is used may also serve as linked certificate transaction that renews the certificate to enable a subsequent use.
