The disclosed technologies include receiving a request from a second computing device to verify ownership of a blockchain address. A challenge content is generated and sent to the requestor. A signature is received comprising a hash of the challenge content generated using a private key. A public key corresponding to the private key is obtained, and the signature is validated using the public key. In response to validating the signature, a characteristic is associated with a user associated with the blockchain address.

A multi-lender architecture is configured to provide a loan applicant with automated pre-qualification and automobile loan eligibility evaluation for multiple candidate lenders. Lender output data may include sensitive data. The lender output data is stored in a data object of a first format and one or more fields of the data object are encrypted at the field level. The encrypted data object may be transmitted through multiple application layers or terminals. The encrypted data object may be reformatted at one or more application layers or terminals without decryption. A reformatted encrypted data object containing the lender output data may be decrypted at the last layer before forwarding the lender output data to the loan applicant.

Systems and methods for verifying a financial transaction based on an account number, a mobile directory number associated with the financial transaction, a mobile directory number associated with the account number, an email address associated with the account number, internet protocol address data associated with the financial transaction, and internet protocol address data associated with accesses of the email address.

A method and system for receiving digital artifacts from a management server. The method includes sending a request for a digital artifact from a mobile application to the management server for display within a specific mobile application generated screen, receiving the digital artifact from the management server, and displaying the digital artifact with the specific mobile application generated screen.

Embodiments relate to progressively validating access token. In response to intercepting an initial call for a transaction for a service from a client, a token is validated for the initial call of the transaction for the service, the validating including contacting an authentication sever and locally storing a time to live received for the token. In response to intercepting at least one successive call for the transaction for the service from the client, it is determined that the token for the at least one successive call is valid based on the time to live locally saved. The at least one successive call for the transaction for the service is permitted to pass without contacting the authentication sever.

A method of providing prescription drug preparation, distribution and delivery services through an electronic prescription. The method includes: executing, by a user terminal, a patient-only application to select a hospital where to receive medical care and whether to receive remote medical care, and transmitting a result of the selection to a cloud server; determining, by the cloud server, whether a hospital appointment and remote medical care are possible based on a selection result received from the user terminal, and requesting, by the cloud server, an appointment and remote medical care to a hospital server available of provision of medical care based on a determination result; proceeding with, by the hospital server, the appointment of the remote medical care and the remote medical care, requesting, by the hospital server, payment of medical expenses from the cloud server, and requesting, by the cloud server, confirmation of medical expenses from the user terminal.

Provided herein is a method for delivering web content to a computer user where the computer user must provide data for verification. A control presented by a first web page provided by a requesting server of a requesting party may be selected to request a further web page where data may be entered that requires verification. The requesting server may redirect the computer user to a verifying server that may provide a second web page to fulfil the request for the further web page. The second web page may be presented as a foreground window positioned over a backdrop frame. The foreground window may be provided with fields for entering the data and the backdrop frame may be provided by the requesting party. The verifying server may verify data entered in the foreground window and may send the requesting server a notification as to whether the verification was successful.

In some embodiments, in connection with an API request to transact with an entity, a first conversion rate associated with a first time may be determined, where the first conversion rate is a current conversion rate for an on-chain asset at the first time; Based on a monitoring of a blockchain, a receipt of the on-chain asset at a second blockchain address from a first blockchain address associated with the user may be detected on the blockchain. In response to the detection, the on-chain asset may be converted to an off-chain asset at a second time associated with a second conversion rate, the second conversion rate being the current conversion rate for the on-chain asset at the second time. An amount of the off-chain asset may be transmitted to the entity, where the amount of the off-chain asset sent to the entity is based on the first conversion rate.

Disclosed is a method to calculate and display carbon emissions impact savings for a metalook or a transaction, by receiving from transaction data sources data items describing the transaction. Each transaction is associated with a user identifier (ID), metalook ID, and garment classification category associated with the metalook ID. For each transaction, a processor calculates, based on an amount of hours spent on garment creation and dressing associated with the transaction and the carbon emissions data for the garment classification category, a carbon emission impact saving associated with the transaction. Calculating carbon emissions impact savings for the transaction may include multiplying the hours on creation and dressing a metalook to a carbon emission multiplier, determined empirically, and subtracting this amount from a physical garment carbon footprint obtained from a database. The carbon emissions value may be displayed to a user.

A method implemented on an augmented reality (AR) electronic device includes receiving a request to activate a transaction card account on a transaction card. The transaction card account is activated on the transaction card. A virtual representation of account information corresponding to the transaction card account is displayed on the AR electronic device. The exterior of the transaction card is free of account identifying information.
