The present invention provides a method for tracking and managing power supplying devices and a blockchain-based system to perform such tracking and monitoring. The method comprises the steps of retrieving recorded characteristic data that is associated with an existing product identification from a blockchain, verifying such recorded characteristic data, generating a new product identification that is connected to the existing product identification and recording the new product identification and new characteristic data in the blockchain. The system comprises a blockchain and a middleware computer to perform the above-mentioned steps. Also provided herein is a blockchain-based system for monitoring and renting a power supplying device.

A blockchain-based privacy protection method for a CCN includes: executing, by a trusted AAC, an initialization algorithm to generate common parameters and a master key, generating a public key and a private key for each consumer and publisher, and randomly generating, by the trusted AAC, its own public key and private key; calculating a public key, and generating ciphertext and uploading the ciphertext to a CSP; performing transaction on-chaining; and during decryption, finding, by the consumer, transaction information of the content on the consortium blockchain, sending an interest packet based on the transaction information, and obtaining ciphertext CT through a storage address in the transaction information; generating, by the consortium blockchain, an access transaction based on access information of the consumer; sending the ciphertext CT to the consumer through a data packet; and locally decrypting, by the consumer, the ciphertext CT, and verifying correctness of the content.

Disclosed herein are apparatuses and methods for verifying video authenticity using blockchain. An implementation may include receiving a video clip from a first source and generating a genesis block of a blockchain, wherein the genesis block includes the video clip, metadata of the video clip, and a first hash value of both the video clip and the metadata. The implementation includes distributing the blockchain to a plurality of nodes in a blockchain network. The implementation includes for each indication received of activity performed on the video clip to be recorded on the blockchain, verifying the activity and generating a new block on the blockchain recording the activity. The implementation includes receiving a modified version of the video clip, verifying an authenticity of the modified version based on each activity recorded in the blockchain, and in response to determining that the modified version is not authentic, generating an alert indicating inauthenticity.

Systems and methods to perform validation of authentication of a security device in a decentralized network are disclosed. In one aspect, embodiments of the present disclosure include a method which can be implemented on a system to, identify telemetry associated with the successful authentication. The telemetry is further in a distributed ledger in the decentralized network and can be used to determine validity of an authentication attempt of the security device by a second user device.

Disclosed are systems and methods that authenticate non-fungible tokens (“NFT”) and/or digital data represented by or pointed to by an NFT. In some implementations, authentication may be with respect to an existing NFT. In other implementations, authentication may be with respect to an NFT that is being created. The disclosed implementations may compare a candidate and/or candidate NFT data with existing NFTs and/or existing NFT data to determine if the candidate NFT and/or candidate NFT data is similar to other NFTs and/or other NFT data of another NFT, which may exist on any of many different blockchains.

An example method of performing interactive videogame verification using cryptographically protected transaction records includes: receiving, by a videogame server, from a first videogame client device, a first transaction record reflecting a first set of events associated with an interactive videogame session, wherein the first transaction record is cryptographically signed by a first private cryptographic key associated with the first videogame client device; receiving, from a second videogame client device, a second transaction record reflecting a second set of events associated with the interactive videogame session, wherein the second transaction record is cryptographically signed by a second private cryptographic key associated with the second videogame client device; and validating the first transaction record based on the second transaction record.

Devices can be configured to implement distributed ledgers capable of immutably recording ledger entries that have validated version identifiers. The devices can include network interfaces, memory and processors. Processors can be configured to obtain ledger entries including version identifiers and version authenticator values, determine software versions that correspond to version identifiers, determine that version identifiers are valid based on version authenticator values, obtain challenges using cryptographic systems, wherein challenges are based on ledger entries, and/or broadcast blocks that incorporate ledger entries to securely add blocks to distributed ledgers. Blocks can be capable of being validated by using cryptographic systems to obtain proofs based on challenges.

A vehicle identifier and a nonfungible token (NFT) associated with the vehicle identifier are stored on an electronic ledger. The electronic ledger is a distributed electronic ledger shared between at least a computer and a remote computer. Upon transitioning a vehicle to an on state, the electronic ledger is queried to identify programming instructions associated with the NFT. Upon retrieving the identified programming instructions from the electronic ledger, the vehicle is actuated based on the retrieved programming instructions.

The present disclosure describes a system, method and computer readable medium for verifying the ownership of an article. In one embodiment, one or more physically unclonable functions may be applied to an article and associated with a non-fungible token in order to create a digital fingerprint. The digital fingerprint may then be stored on a blockchain network and utilized to verify and authenticate the ownership of the article.

Systems, computer program products, and methods are described herein for the divergent distribution of electronic digital certificates. The present invention may be configured to generate an electronic digital certificate associated with an artifact, store the electronic digital certificate on a distributed ledger, and record, on the distributed ledger, an interest of the user in the electronic digital certificate. The present invention may be configured to receive a request from the user to divide ownership of the electronic digital certificate amongst a group of users. The present invention may be configured to determine shares in the electronic digital certificate by determining for each user of the group of users a share of the shares. The present invention may be configured to record, on the distributed ledger and based on the shares, interests of the group of users in the electronic digital certificate.
