Abstract: Multiple video game consoles each store a blockchain ledger with multiple blocks, which is either associated with a particular video game or with a the particular type of video game console that the video game consoles are each characterized by. One of the consoles receives a message identifying an intended transaction corresponding to transfer of an identified quantity of an in-game virtual asset from a transferor account to a transferee account. The console verifies that the intended transaction is valid and generates a new block that includes the transaction, optionally one or more additional verified intended transactions, and a block header that includes a hash of a most recent block in the blockchain ledger. The console appends the new block to the blockchain ledger and transmits it to the other consoles, which each also append the new block to their copy of the blockchain ledger, thereby completing the transaction.

Abstract: A payment-enabled mobile device is placed in communication with a POS (point of sale) terminal to facilitate a purchase transaction.

Abstract: Systems and methods for controlling distributions by an automated electronic networked central clearinghouse are disclosed. Exemplary implementations may: receive an exchange request that indicates a first user offers a first digital asset for a reversible exchange on a fiat-currency-based online exchange platform; obtain asset-specific distribution rights for the first digital asset; receive exchange information regarding the reversible exchange with an exchanging user; monitor, during a waiting period, whether any actions taken by the exchanging user determine reversibility of the reversible exchange, or whether the waiting period for reversibility times out; based on a time-out or a determination regarding reversibility, either (i) transfer the ownership of the first digital asset to the first user, or (ii) clear the reversible exchange by non-temporarily transferring the ownership to the exchanging user, and by distributing benefits in accordance with the asset-specific distribution rights.

Abstract: A payment system implemented on a mobile device authenticates transactions made via the mobile device. The mobile device generates a public-private key pair and receives an authenticating input from a user of the device. The public key is sent to a secure payment system, and the authenticating input is used to generate a symmetric key that encrypts the private key. After a transaction is initiated, the mobile device receives an authenticating input from the user. The symmetric key is generated from the authenticating input and the mobile device attempts to decrypt the private key from the encrypted private key using the symmetric key generated by the user's input. The decrypted key is used to sign a transaction authorization message which is sent to the secure payment system, along with payment information, which can verify the signed message via the public key. Additional techniques related to secure payments are also disclosed.

Abstract: Technologies are shown for controlling a transaction on a digitally stored blockchain by creating a contract data block for a transaction involving entities and by event code executed after receipt of digital signatures from the entities. A refund transaction may be digitally signed by entities and linked to the contract block within the blockchain. A payment transaction block may also be digitally signed by entities and linked to the contract block. Code authorized to execute by the blocks executes based on receipt of digital signature events.

Abstract: Measures, including methods, apparatus and computer software are provided for processing electronic tokens. An authorization request is received in relation to processing of an electronic token. An identifier for a user terminal associated with the electronic token, and an account, are determined on the basis of the authorization request. In some arrangements, a location query for the user terminal is performed on the basis of the determined identifier, whereby to determine a location of the user terminal on the basis of a proximity of the user terminal to one or more base stations in a cellular telecommunications network. In some arrangements, a challenge message is sent to the user terminal, to establish a confidence that the transacting user terminal is the designated user terminal. Processing of the electronic token in relation to the account is selectively authorized on the basis of the result of the location query or challenge response.

Abstract: A method and apparatus for processing secure transactions of a requested service at a merchant point of sale (POS) using a customer mobile device and a virtual payment gateway (VPG) server, the method comprising an authentication and a transaction. The activation establishes a mobile device transport key (mTK) at the mobile device and a server, and assigns a mobile application identifier (MAID) to a mobile application of the mobile device. The transaction is based on generating a mobile device transport session key (msTK) derived from a server generated session ID and the mobile device transport key (mTK) generated during activation. The transaction of the requested service is initiated by the customer mobile device and is processed without storing confidential data such as financial account data or financial account identification data at the POS and/or the customer mobile.

Abstract: The Social Data Tracking Datastructures, Apparatuses, Methods and Systems (“SDTD”) transforms brokerage order request, blockchain transaction request, agency action request inputs via SDTD components into brokerage order confirmation, transaction confirmation, agency action notification outputs. An agency action request is obtained from a user of an agency oversight configured blockchain. A transaction identifier of an unwind transaction associated with the agency action request is determined. An unwind address associated with the agency action request is determined. The agency oversight configured blockchain is analyzed to determine an affected transaction for the unwind transaction, wherein the affected transaction involves unspent crypto tokens that originated from the unwind transaction. An agency blockchain transaction request that facilitates transferring crypto tokens from an address associated with the affected transaction to the unwind address is generated.

The transaction scoring model uses a plurality of global profile variables, each of the plurality of global profile component instances using its own global profile partition that contains the estimate of global profile variables and being configured for update by a dedicated thread of execution of the real-time transaction scoring system, each dedicated thread being configured for receiving and scoring a portion of input transactions.

Abstract: The methods described herein are configured to obtain a first record pattern associated with the unidentified entity and select a second record pattern associated with an entity identifier of a known entity. Based on the first record pattern matching the second record pattern, the entity identifier of the known entity is associated to the unidentified entity to indicate that the unidentified entity and the known entity are the same. Determining the entity identifier of the unidentified entity enables the linking of separate identifier systems of data structures to facilitate communication and/or interaction between the data structures.
