Some examples of the present disclosure relate to infusing custom qualities into an artificially intelligent entity. In one example, a system can initiate execution of a smart contract that is configured to generate a correlation between a second non-fungible token (NFT) and a first NFT. The first NFT can include personality fields with default values defining default personality characteristics for an artificially intelligent entity. The second NFT can include a personality field with a customized value defining a customized personality characteristic assignable to the artificially intelligent entity. The correlation can be configured to impart the customized personality characteristic to the artificially intelligent entity.

Devices, systems, and methods are provided for blockchain tokens and ledger for medical and dental transactions. A method may include determining a cost of a healthcare service provided to a patient by a healthcare provider; accessing a blockchain digital ledger; identifying a digital wallet of the patient stored using the blockchain digital ledger; identifying, a digital token stored in the digital wallet, the digital token restricted to payment for the healthcare service and issued by an insurer; transferring, based on a smart contract of the blockchain digital ledger, the digital token from the first digital wallet of the patient to the healthcare provider; determining a difference between the cost and a pecuniary amount provided by the digital token; and generating a bill for the patient, the bill indicating that the patient owes the difference to the healthcare provider.

Techniques are described, as implemented by computing devices, to control access to transactions through use of tokenized reputation scores. This is performed by leveraging a blockchain such that a tokenized reputation score is generated or calculated based on an amount of reputation tokens associated with a blockchain account address associated with a service provider account, and by making transactional functionality available to the service provider account based on a comparison of a tokenized reputation score affiliated with the service provider account with a threshold score associated with a transaction.

Techniques are described, as implemented by computing devices, to provide digital content to users through use of nonfungible tokens (NFTs). This is performed by leveraging a blockchain such that digital content associated with an item is made available to encourage the user to interact with NFTs on the service provider platform (e.g., discounts, NFT listing functionality, automatic initiation of NFT transfers, and so forth) based on a user's possession of the NFT.

Disclosed are various embodiments for using custodial systems to maintain ownership of digital assets and facilitate transfers of digital assets between individuals. To facilitate a user taking possession of a digital asset, the custodial system could update an owner identifier for a digital asset in an asset ledger to include a public key of an asset custodian, the public key of the asset custodian indicating that the asset custodian is the owner of the digital asset. The custodial system could then provide a verifiable credential to an identity wallet, the verifiable credential being linked to the digital asset in the digital asset ledger. Subsequently, the custodial system could create an asset record that stores an owner identifier in association with an asset identifier for the digital asset, the owner identifier representing a user of the identity wallet.

Methods and apparatus for enabling a proximity payment device to generate dynamic data for securely conducting a transaction by emulating a magnetic stripe payment card. In an embodiment, a mobile device processor transmits information to a digital enablement service computer to activate a simulated magnetic stripe payment wallet application stored in the mobile device. The mobile device then receives one or more cryptographic keys, generates an unpredictable number (UN), generates dynamic CVC3 data based on the UN, and then assembles emulated magnetic stripe data. During initiation of a purchase transaction, the mobile device processor transmits the emulated magnetic stripe data to a communications interface associated with a merchant device.

Systems and methods are described for provisioning access credentials to a mobile device using device and authorization codes. Once provisioned, a mobile device can be used to conduct a transaction.

Apparatuses, methods, and systems are disclosed for user authentication using a connection information package provided by a blockchain network. One apparatus includes a processor and a transceiver that receives, from a first address on a blockchain network, a plurality of connection information packages and also receives, from a first function, a request to authenticate a user. The processor determines whether the first function is associated with one of the plurality of connection information packages. In response to the first function being associated with a valid one of the plurality of connection information package, the processor accepts the request to authenticate a user.

A method for processing a transaction of a communications terminal, asking a server, through a communications network, for processing of a transaction involving the use of payment data. The method is implemented within the communications terminal. The method includes: transmitting a request for obtaining a certification code to the payment method whose data is used for the transaction; receiving the certification code coming from the payment method; inserting the certification code into a transaction data structure; transmitting the transaction data structure to the server; and when the certification code received by the server is valid, receiving a piece of data representing the validation of the transaction by the server.

A sensor device for conducting electronic transactions from a vehicle including a housing including an RFID circuit operably connected to an RFID antenna, a short range communication device, the RFID circuit and short range communication device operably connected to a processor, and a power supply. The sensor device is wirelessly connectable to a mobile communication device via the Bluetooth chip and the mobile communication device runs a software application. The RFID antenna is adapted to receive a wireless signal from a transmitter. Responsive to the wireless signal, the processor causes the short range communication device to wirelessly communicate with the mobile communication device to initiate a transaction.
