Abstract: A process for combining domain restriction and remote authentication may include receiving a token from a plug-in application to conduct a transaction associated with a user of a communicating device. The process may include sending an authentication request to a remote access control sever to authenticate the user, and receiving, from the remote access control server, an authentication tracking value that the remote access control server used in generation of an authentication cryptogram. The process may also include generating, using the authentication tracking value, a domain restriction cryptogram that is used for domain restriction of the token, and sending, to the plug-in application, the domain restriction cryptogram.

Abstract: Delegating issuance capability to a third-party of fungible digital assets involves a central (e.g., central bank) processor receiving a request to issue fungible digital assets from a third-party node; verifying the request; validating request to issue fungible digital assets from the third-party; approving or rejecting the request; if the request to issue fungible digital assets is approved, creating an issuance authorization message; executing a smart contract clause to add an entity of the third-party node to a list of authorized entities; publishing the issuance authorization message on a blockchain indicating that a third-party node has been added to the list of authorized entities; and publishing a revocation message on the blockchain revoking an authorization granted to the third-party node to issue digital assets.

Abstract: Disclosed are examples of a method, a wearable device and a system enabling authentication of a user of a payment account or completion of a purchase transaction via signals generated by the wearable device. A process may include a wearable device generating a modulated signal using an encryption algorithm. The modulated signal may contain authentication information related to the wearable device including a cryptographic authentication message. The modulated signal is output to a biological medium interface of the wearable device that is coupled to a biological medium of a wearer of the wearable device. The biological medium is operable to conduct the modulated signal. A receiving device processes including decrypting and demodulating the modulated signal received from the biological medium. Using the demodulated signal, the authentication information transmitted from the wearable device is obtained. Based on the obtained authentication information, a transaction may be authorized, or a user authenticated.

Abstract: A method of displaying a multi-layer digital asset in a digital environment includes retrieving, from a digital blockchain ledger, data associated with a first, primary non fungible cryptographic token (NFT) and data associated with a second, sub-asset NFT. The data associated with the first NFT identifies a first retrieval location of a first digital graphics file that is representative of a primary digital asset. The data associated with the second NFT identifies a second retrieval location of a second digital graphics file. The method includes retrieving, the first digital graphics file from the first retrieval location, retrieving the second digital graphics file from the second retrieval location, layering an image from the second digital graphics file onto the primary digital asset to form the multi-layer digital asset, and displaying the multi-layer digital asset in a digital environment.

Abstract: An online store can transmit an online account token to an electronic device or to a biometric sensing device after a user successfully enters his or her account password. The electronic device or the biometric sensing device can countersign the online account token when the one or more biometric images match reference biometric images and the account password matches user identifier data stored in the electronic device or in the biometric sensing device. The countersigned online account token can then be transmitted to the online store. The user can then make one or more purchases after the online store receives the countersigned online account token.

Abstract: Quantum security may be enhanced through the use of quantum-safe validators for transactions whereby the quantum-safe validators process quantum-safe addresses and signatures of parties to the transactions. Quantum safety may be added to conventional blockchain transactions, for example, via smart contracts which are executed using cryptographic interlocks to between conventional smart contract execution engines and quantum-safe validators to ensure both quantum-safe processing of addresses and signatures and legitimacy of quantum-safe validators in presenting transactions for incorporation on the chain.

Abstract: This disclosure describes techniques for implementing a blockchain to manage license compatibility. The techniques include parsing a code segment in a version of source code based on one or more parsing parameters, wherein the code segment is associated with a transaction and distributed under a license. Thereafter, one or more blocks are inserted onto a blockchain distributed ledger recording the transaction. Upon receiving an updated version of the source code comprising a change to at least one code segment associated with a new transaction, additional blocks are inserted onto the ledger recording the new transaction. Based at least on the transaction recorded in the blocks, the license associated with the version of the source code is identified. Additionally, a flag may indicate license incompatibility with the license if the change to at least one code segment associated with the new transaction violates a license restriction of the identified license.

Abstract: An apparatus including processing circuitry and a method are described. When receiving a cross-chain transaction request to transfer a resource from a first account to a second account, the processing circuitry is configured to generate a task corresponding to the first account. The task can indicate conditions for implementing events in transferring the resource. A first blockchain system provides services for the first account, and a second blockchain system different from the first blockchain system provides services for the second account. The processing circuitry transfers the resource to the second account based on the task when a first plurality of first nodes in the first blockchain system reaches a consensus on a generation event of the task and updates a task status of the task to being finished when a plurality of second nodes in the second blockchain system reaches a consensus on a transfer event of the resource.
