Abstract: In order to validate a user to facilitate conducting a high-valued financial transaction via wireless communication between an electronic device (such as a smartphone) and another electronic device (such as a point-of-sale terminal), the electronic device may authenticate the user prior to the onset of the high-valued financial transaction. In particular, a secure enclave processor in a processor may provide local validation information that is specific to the electronic device to a secure element in the electronic device when received local authentication information that is specific to the electronic device (such as a biometric identifier of the user) matches stored authentication information. Moreover, an authentication applet in the secure element may provide the local validation information to an activated payment applet in the secure element. This may enable the payment applet to conduct the high-valued financial transaction via wireless communication, such as near-field communication.

Abstract: Systems and methods for secure digital asset transactions. An offline system includes a custodian computer, digital asset accounts accessible by the custodian computer and a centralized ledger maintained by the custodian computer. The custodian computer is in communication with public ledger computers of a public ledger, and receives transaction data associated with digital assets from among entity computers. Each account is prefunded with digital asset funds. The custodian computer monitors a transaction parameter of the transaction data and, in accordance with the monitoring, generates a transfer instruction indicating transfer of funds between the first and second accounts, updates the centralized ledger responsive to the transfer instruction, and transfers the funds between the first and second accounts, responsive to the transfer instruction. The transfer instruction remains offline and is not transferred to the public ledger.

Abstract: Healthcare transaction validation systems and methods are presented. Healthcare transactions associated with a stakeholder are compiled into a chain of healthcare transaction blocks. The chain can be considered a chronicle of person's healthcare path through life. When a transaction is conducted, the corresponding healthcare parameters (e.g., inputs, outputs, clinical evidence, outcomes, etc.) are sent to one or more validation devices. The devices establish a validity of the transaction and generate a new block via a proof-of-work principle. Once the new block has been calculated it can be appended to the stakeholder's health care blockchain.

Abstract: A game reward system is described herein that pays players to play a video game. The system does this by utilizing the unused resources of the player's computing device to perform cryptographic hashes and mine one or more cryptocurrencies. The game reward system generates a jackpot based on the cryptocurrency that has been mined, allocates some amount to the system operator for profit of running the system (e.g., 10%), and divides the remaining amount among the players of enough rank as a reward. Instead of charging people to buy a game, the game maker using the game reward system can make the game free for players to play. Thus, the game reward system completely changes the business model of games, makes games more fun, and rewards players in a new way for playing games.

Abstract: An example method includes receiving an encrypted biometric enrollment data and user identifier data. The encrypted biometric enrollment data includes at least one biometric enrollment sample from a user encrypted using an encryption key. The encryption key is generated based on a user secret and the user identifier is associated with the user. The user identifier is matched with a stored user secret. A decryption key is generated based on the stored user secret. The encrypted biometric enrollment data is decrypted using the decryption key. The at least one biometric enrollment sample is retrieved from the decrypted biometric enrollment data. The at least one biometric enrollment sample is processed using a biometric processing algorithm to generate a biometric reference template. A biometric reference template identifier uniquely identifying the biometric reference template is generated. An encryption key is generated based on the stored user secret and encrypts an enrollment confirmation message.

Abstract: Described herein are systems and methods for virtualizing policy enforcement amongst participants of an overlay network. In some embodiments, each of the participants may maintain a separate blockchain network. The overlay network may receive smart contracts or other policy documents that include information on interactions with a particular participant or between participants. A controller, which may be implemented on any node of the overlay network, may then extract an interaction algorithm from that smart contract that may be stored in policy data to be used in completing transactions between two participants of the overlay network. In some embodiments, the policy data may include cost data which may be used to determine how two entities may interact.

Abstract: A system is disclosed for a digital rights management system which enforces license rights by establishing an account domain of registered consumer devices which may each receive a decryption key to be used to decode digital content bought by any of the devices within the account domain. Such system further enables the decentralization of content sharing by establishing a network of trusted intermediate devices to manage licenses on end devices for a central rights provider.

Abstract: Systems and methods for servicing vehicle messages utilizing a common communications infrastructure are provided. A method includes obtaining, by a vehicle computing system onboard an autonomous vehicle, a message including a cryptographic signature and contextual information, a request, or a command.

Abstract: Techniques described herein relate to tracking and analyzing digital credential usage in sensor-monitored environments. A digital credential platform server may receive data identifying credential receivers, and then retrieve the digital credentials generated and issued to the credential receivers. The digital credential platform server may then determine sets of physical activities associated with the digital credentials issued to a credential receiver, and may use sensor-based monitoring systems to detect the user actions of the credential receiver and compare those actions to the physical activities associated with the credentials. Comparisons between the user actions detected for the credential receiver, and the physical activities associated with the receiver's credentials, may be used to determine re-credentialing time periods, credential expiration times, and the like.

Abstract: A computer can monitor network traffic on a blockchain computing network. The computer can determine a current level of network congestion on the blockchain computing network. The computer can execute a first machine learning model that predicts a timeseries of future transaction costs based on historical data and the current level network congestion level of the blockchain computing network.

Abstract: Systems and methods for effecting secure transactions are described. A processing device, when executing computer-executable instructions: receives from a requesting entity computing system a transaction request for a payload. The transaction request is transmitted to delivery entity computing system associated with a delivery entity identifier and geographic location. An encryption key, random number and a unique request identifier are generated and transmitted to requesting and delivery entity computing systems. In response to receiving a delivery transaction confirmation from the delivery entity computing system, the processing device verifies the secure transaction. After receiving a requestor transaction confirmation from the requesting entity computing system (indicating a verified transfer of the payload), a payload reimbursement is transferred to a delivery transaction account from a requestor transaction account.
