Abstract: Systems and techniques for ownership-directed functionalities within NFT platforms are illustrated for determining ownership over a token. The method receives a transaction request, wherein the transaction request seeks to grant ownership access to a first token over a second token. The transaction request includes a first token identifier corresponding to the first token; and a second token identifier corresponding to the second token. The method assesses whether the transaction request is authorized. When the transaction request is assessed to be authorized: the method obtaining a mapping including: the first token identifier, and a record of tokens owned by the first token; and grants ownership access over the second token to the first token, based on the mapping and the second token identifier. Granting ownership access over the second token to the first token includes adding the second token identifier to the record of tokens owned by the first token.

Abstract: One embodiment includes a method that recovers information on one or more characteristics of a node, wherein the information corresponds to at least one selected from the group consisting of: hardware, software, event history, and functionalities. The method derives one or more characterizations of the node based on the information. The characterizations reflect a current state of a characteristic of the one or more characteristics. Characterizations are expressed as statements on a blockchain. The method recovers, from an assertion unit, an assertion verifying validity of the characterizations. The method derives a reputation score for the assertion unit, wherein the reputation score discloses estimates of verification accuracy for the assertion unit. The method determines a risk score for the node based on the reputation score, the characterizations, and the assertion, wherein the risk score corresponds to a degree of risk associated with transacting with the node.

A block that incorporates the ledger entry can be broadcast to securely add the block to the distributed ledger.

Abstract: A method and apparatus for location sharing, consisting of sending a location report by a location determining device to a plurality of network enabled devices over a peer-to-peer network, the location determining device being associated with a first digital key pair. A first of the plurality of network enabled devices, associated with a second digital key pair, performs a validation computation on the location report and submits a validation computation result and the location report to a remainder of the plurality of network enabled devices for inclusion in a shared ledger. Including the location report creates commercially-valued credits associated with the public key of the second digital key pair recorded in the shared ledger. A transfer of commercially-valued credits from association with the first public key of the first digital key pair to the public key of the second digital key pair is also recorded in the shared ledger.

Abstract: A method and apparatus is presented for announcing the existence of cryptographic key pairs within a distributed ledger system in which no central trusted authority is available, consisting of sending a key announcement message by a network connected device to other network connected devices over a peer-to-peer network for inclusion in the distributed ledger. Once a valid key announcement message for a public key is included in the ledger, any future transactions that reference an address associated with the public key or other messages concerning said public key are accepted by other network connected devices on the peer-to-peer network and are included in the distributed ledger. If transactions or other messages reference an address not associated with an announced public key, they may be rejected by the peer-to-peer network and may not be included in the distributed ledger.

Abstract: A system and method for ensuring digital integrity of a blockchain is presented. The blockchain is initiated with one or more digital certificates presented in one of an initial set of blocks of the blockchain. One or more of the digital certificates may subsequently be used to sign a hash of a sequence of blocks in the blockchain at regular or semi-regular intervals. If a sequence of consecutive blocks is longer than a predetermined number and does not contain a signature from one or more of the digital certificates of a hash or one or more of the blocks in the sequence, the sequence may be considered not to comprise a part of the blockchain. In other embodiments side blocks may be signed and added to the blockchain.

Abstract: A radio frequency identification device, or RFID tag, has an antenna attached to or formed on a microchip. The microchip usually comprises low power fixed or programmable logic and a small quantity of persistent memory. As many RFID tags are powered by radio waves transmitted from an RFID tag reader, the low power fixed or programmable logic is often not capable of performing complex cryptographic calculations required for digital signing to provide one-way authentication of the tag. In the present disclosure a system and method are presented for enabling a low overhead challenge and response using a one-time password pad comprising passwords on the RFID tag and a blockchain to record a use of the passwords. Methods are also disclosed for securely replacing the one-time password pad, and using the RFID tag in combination with a blockchain to provide provenance information for the RFID tag.

Abstract: Identity and access management in computer systems without the need for a central authority is provided. A user may create an identity on a blockchain, and generate a one-time pad of access passwords derived from repeated hashing of a master password and cryptographic salt. The user may publish a last access password from the one-time pad on the blockchain. The user may then provide proof of identify in response to an access challenge by revealing a prior access password from which the last access password is derived, and may receive a session token in response. The publishing of access passwords and receiving of session tokens may be associated with a transfer of tokens or digital credits of commercial value on the blockchain.

Abstract: A method and apparatus is presented for reaching consensus on adding data to a distributed ledger system in which no central trusted authority is available, comprising sending an announcement message by a network connected device to a plurality of network connected devices over a peer-to-peer network, said message providing an identification of the network connected device using a public key of a public/private key pair, a unique address identifier, and a hash. Subsequently, after a waiting period measured in, for example, time or blocks of data, the network connected device may submit data for inclusion in the distributed ledger. If the announcement message and preceding data in the distributed ledger satisfy a predetermined condition, the plurality of network connected devices may include the data in the distributed ledger. If the network connected device fails to submit the data when the predetermined condition is satisfied, the announcement message may be canceled.
