A method including receiving a first application user credential associated with a user profile; comparing, for a first match, the first application user credential with a stored second application user credential, wherein the stored second application user credential is associated with a user identity; and responsive to finding a first match, verifying the user identity by performing the following: communicating with a card using near field communication; receiving a public key of a key pair of the card and cardholder identification information of an account holder of the card; instructing the card to generate a digital signature; receiving the digital signature from the card; verifying the digital signature using the public key; and comparing, for a second match, at least a portion of the user identity with at least a portion of the cardholder identification information.

Methods for providing provable access to a distributed ledger with a tokenized instruction set are disclosed. A method may include accessing a distributed ledger including an instruction set, tokenizing the instruction set, interpreting an instruction set access request, and in response to the instruction set access request, providing a provable access to the instruction set.

Some embodiments of the application disclose a method and apparatus for paying a fare. When a user takes a public transit means, the user terminal establishes an NFC connection with the fare-collecting device of the public transit means, the user terminal transmits the encrypted account ID of the user to the fare-collecting device, and the fare-collecting device may request a server to deduct the fare from the account of the user.

Systems and methods for machine forward energy transactions optimization are disclosed. A transaction-enabling system may include a resource requirement circuit to aggregate a resource requirement for a fleet of machines to perform a task, a forward resource market circuit to access a forward market for energy, and a controller. The controller may include an artificial intelligence (AI) circuit to configure a transaction on the forward market for energy in response to the aggregated resource requirement and a machine resource acquisition circuit to automatically solicit the configured transaction on the forward market for energy. The AI circuit may also iteratively improve the configured transaction to improve a task outcome of the fleet of machines.

Computer-readable media, systems and methods may improve an ability to validate a multipart transaction involving multiple parties and sub-transactions and securely store and access multipart transaction data through a peer-to-peer computer network and a distributed ledger. A multipart transaction, such as a Murabaha transaction, may refer to a transaction having multiple parts involving multiple parties in connection with an agreement between two or more of the parties in which a commodity sale or other vehicle is created based on the agreement. The commodity may be tokenized for transfer in the multipart transaction. Validation of digitally signed data relating to the sub-transactions may provide secure authentication of the sub-transactions and atomic transfers of the tokenized commodity between relevant parties of sub-transactions in connection with the agreement. Storage of the validated sub-transactions and transfers on the distributed ledger may provide secure, immutable, and transparent proof of the validated sub-transactions and transfers.

Systems and methods for fleet forward energy and energy credits purchase are disclosed. An example transaction-enabling system may include a resource requirement circuit to aggregate a resource requirement for a fleet of machines to perform a task; a forward resource market circuit to access a forward market for energy; and a machine resource acquisition circuit to execute a transaction on the forward market for energy in response to the aggregated resource requirement.

Systems and methods for machine forward energy and energy storage transactions are disclosed. An example transaction-enabling system may include a resource requirement circuit to aggregate a resource requirement for a fleet of machines to perform a task, wherein the resource requirement comprises an energy storage capacity requirement, a forward resource market circuit to access a forward market for energy, and a machine resource acquisition circuit to execute a transaction on the forward market for energy in response to the aggregated resource requirement.

Systems, methods, apparatuses, and computer-readable media for secure generation of one-time passcodes using a contactless card. In one example, an operating system (OS) of a device may receive a uniform resource locator (URL) and a cryptogram from a contactless card. The OS may launch an application associated with the URL. The application may transmit the cryptogram to an authentication server. The application may receive a decryption result from the authentication server indicating the authentication server decrypted the cryptogram. Based on the decryption result, the application may request an OTP. The processor may receive an OTP from an OTP generator. The application may receive an input value and compare the input value to a copy of the OTP. The application may determine that the comparison results in a match, and display, based on the determination that the comparison results in the match, one or more attributes of the account.

A central computer system transforms identification information of a consumer into an identity code that hides the identification information and stores it with contact information of a consumer's computer system. When a computer system on the network of the central computer system conducts a transaction with a subject who uses the identity code of the consumer, the central computer system contacts the consumer's computer system so that the consumer can stop the transaction if it is not authorized. Because only the identity code is used to protect the consumer, the original identification information of the consumer is fully protected.

Systems and methods for authentication may include a first device having an association with a first account, including a memory containing one or more applets, a counter value, and transmission data, a communication interface, and one or more processors in communication with the memory and communication interface. The first device may create a cryptogram based on the counter value, wherein the cryptogram includes the counter value and the transmission data. The first device may transmit, after entry of the communication interface into a communication field, the cryptogram, and update, after transmission of the cryptogram, the counter value. The first device may receive, via the communication interface, one or more encrypted keys and one or more parameters. The first device may decrypt the one or more encrypted keys and, after decryption of the one or more encrypted keys, switch an association from the first account to a second account.
