Scan matching can be used for art authentication. A digital scan of at least a portion of the authentic painting (or other type of artwork) is created. If a scan exists that is trusted to be a digital image identifying the authentic artwork, a subsequent scan can be created of the work a buyer intends to purchase. If the subsequently created scan matches the trusted scan of the artwork, the buyer can conclude that the artwork to be purchased is the authentic one. The trusted scan passes to the buyer as a blockchain transaction.

The present invention relates to a system and method for intelligently locking and authenticating handicraft objects, the system and method being based on a unique vibrational signature specific to each object. The system comprises three main components: (1) a detection module incorporating a multi-connected WTVB01-BT50 vibration sensor for capturing and analysing, in real time, the specific vibrations of the object, (2) a generation module comprising a programmable vibration generator and a verification box with bidirectional communication, and (3) a distributed storage module using the Blockchain and IPFS to ensure secure traceability of the vibrational signatures while incorporating a generative artificial intelligence model making it possible to optimise authentication by dynamically recalibrating the signatures according to natural alterations of the object, thereby ensuring more accurate identification. In addition, all modifications and interactions are recorded on the Blockchain, ensuring reliable and transparent tracking of the life cycle of the object, while offering effective protection against counterfeiting and preserving its authenticity and history.

Certain aspects provide techniques for securely generating wallets for transactions on a blockchain. An example method generally includes receiving, at a first node, a request to generate a wallet on a blockchain. A first private share associated with the first node is generated for the wallet. A salted second private share for the wallet is received from a second node. Generally, the salted second private share is associated with a shared salt shared by the first node and at least the second node. A chain code associated with wallets generated by the first node is generated based on the first private share and the salted second private share. A wallet is generated based at least on the chain code. Generally, the wallet is defined based on wallet private shares for signing transactions on the blockchain and a wallet public key for verifying transactions on the blockchain.

The present disclosure relates to a method for secure blockchain transactions using a decentralized multi-hop proxy network (DMHPN). The method comprises obtaining an encrypted message containing original transaction information, which is routed through a plurality of proxy nodes. Each proxy node decrypts its respective segment using a unique Elliptic Curve Diffie-Hellman (ECDH) shared encryption key to determine the next hop. The final proxy node decrypts the complete transaction data and submits it to the blockchain. The encrypted message excludes identifiers of the transaction initiator and destination blockchain node, enhancing privacy. This method improves security and decentralization by making only the intended proxy node access its segment of the data, maintaining anonymity throughout the transaction while preventing unauthorized access and ensuring privacy in blockchain interactions.
