Abstract: A computer-implemented method includes: transmitting, by a mobile device, to a mobile wallet computer system, an indication that a user of the mobile device wishes to perform a mobile wallet transaction to transfer funds to a merchant; receiving, by the mobile device, an amount of merchant rewards that are available for the user to use at the merchant; displaying, by the mobile device, the amount of merchant rewards; receiving, by the mobile device, an indication that the user wishes to apply at least a portion of the available rewards to the transaction; and, transmitting, to a merchant computer system, the indication that the user wishes to apply at least a portion of the available rewards to the transaction. The merchant rewards are applied to the transaction prior to submitting the transaction to a card network computer system, and no physical rewards card is used to complete the transaction.

Abstract: Methods and systems for blockchain token-based access control in which an access control rule sets an access condition that is satisfied if a wallet address holds one or more specified non-fungible tokens or tokens having specified attributes. To conduct in-person or on-location token-based gating, the system may employ pre-authentication of a wallet address. An identifier may be stored securely on both the system and a user device following pre-authentication. When seeking access, a user device provides identification data generated based on the identifier and the system verifies that the identification data was generated based on the identifier and, on that basis, retrieves a pre-authenticated wallet address. It then verifies using blockchain data that the wallet address holds the requisite token or tokens to satisfy the access condition.

Abstract: Systems and techniques are described for token device transfer management. A system identifies, in a payload of at least one block of a distributed ledger, a token corresponding to media content. A parameter of the token in the distributed ledger indicates that the token is associated with a first user. The system identifies a device that is associated with the token and the media content. The device is also associated with the first user. The system identifies that the device has been relocated to an area associated with a second user. In response to identifying that the device has been relocated to the area, the system causes the parameter of the token in the distributed ledger to be modified from indicating that the token is associated with the first user to indicating that the token is associated with the second user.

Abstract: A network-based service creates a smart contract on a blockchain on behalf of a user who has a loan or a subscription that requires installment payments be collected by a provider from the user and provided to creditor of the loan or subscription. The smart contract associates a default account of the user with a first access token and non-default registered other accounts of the user with a second access token. The smart contract when presented with the access tokens from a provider determines whether the payment due can be satisfied from a current balance of the default account and if so, transfers the payment from the default account to the provider. If the default lacks sufficient funds for the payment, the smart contract proportions the amounts taken from each of the accounts to reach the amount due and transfers the amount due to the provider.

Abstract: A blockchain agnostic token network is described. In an example, a request to purchase a non-fungible token (NFT) minted on a blockchain from a seller is received. Based at least in part on context data associated with at least one of the user, the seller, or a digital asset associated with the NFT, a plurality of available blockchains is determined for holding the NFT. Information associated with the plurality of blockchains is surfaced and one of the plurality of blockchains is determined for holding the NFT. Based at least in part on the determined blockchain, the NFT is transferred to the determined blockchain and associated with a user account for subsequent viewing.

Abstract: Example embodiments provide systems and methods for increasing the cryptographic strength of an encryption or message-authentication-code-(MAC) generation technique. According to some embodiments, a MAC may be constructed around a shared secret (such as a random initialization number), thereby increasing strength of the MAC against brute force attacks based on the size of the shared secret. The MAC may be combined with randomized data, and may also be encrypted to further bolster the strength of the code. These elements (shared secret, MAC algorithm, and encryption algorithm) may be employed in various combinations and to varying degrees, depending on the application and desired level of security. At each stage, the cryptographic construct operates on the cyptographically modified data from the previous stage. This layering of cryptographic constructs may increase the strength of the group of contrasts more efficiently than applying any one construct with a larger key size or similar increase in complexity.

Abstract: A dynamically regulated advertising delivery control system. A campaign is operated by sending bids to an exchange responsive to receiving bid requests from the exchange, each bid request representing an opportunity to expose a browser to content. Won bid notifications are received from the exchange and exposure notifications are received from exposed browsers. Failed exposures are detected by detecting won bid notification identifiers without corresponding exposure notification identifiers. Responsive to the failed exposures exceeding an upper limit, the campaign is operated in a throttled mode. Responsive to detecting successful exposures in the throttled mode, the campaign is operated in a recovered mode.

Abstract: Disclosed herein is a user identity sharing system utilizing a distributed ledger technology security platform. The present invention includes an OFF-CHAIN configured to operate as a regional or national blockchain within a single jurisdiction, in which one or more virtual asset service providers and one or more identity management service providers are participating; and an ON-CHAIN configured to operate as a global blockchain with no borders, in which one or more virtual asset service providers are participating, wherein user identity information of the OFF-CHAIN are shared as de-identified identity information between a virtual asset service provider participating in both the OFF-CHAIN and the ON-CHAIN and another virtual asset service provider participating in the ON-CHAIN, thus preventing forgery of user identity information, and sharing user identity information between virtual asset service providers, other blockchains, distributed ledger technology platforms, and existing IT systems.

Abstract: Systems and methods are described herein for resolving advertisement placement conflicts. Specifically, a number of parameters may be entered into a system in order to distribute advertisements into advertisement slots. In many instances, a combination of these parameters causes a conflict in the system where all the parameters cannot be applied in order to place advertisements into advertisement slots. The conflict may be resolved by using an advertisement assignment model to determine which parameters may be relaxed in order to arrive at an optimal solution that violates a smallest number of parameters having the least priority. When such a solution is found, the advertisement assignment model may be modified and advertisements may be placed into advertisement slots based on the modified advertisement assignment model.
