An identity system is provided that may include an attestation service that is configured to communicate with a user computer device and a blockchain platform, and create a blockchain account for the attestation service on the blockchain platform, the account having an associated backend blockchain identity application. The attestation service may further be configured to determine that a user of the user computing device owns a user blockchain account by obtaining a signed message of the user. The signed message may include a user access token from the user of the user computer device and a blockchain address of the user to associate with the access token, the user access token having been generated by a trusted identity provider service. The attestation service may further be configured to identify one or more identity claims associated with the token, and store the identity claim for future presentation to a third party.

This disclosure describes techniques for authenticating a person that seeks to engage in a voice call session with a call center agent, an interactive voice response system, or other system. In one example, this disclosure describes a method that includes storing information associating an authorized device with an account; receiving, over a network and from a device operated by a user, authentication credentials for the user; determining, based on the authentication credentials, that the user is authorized to access the account; receiving, over the network and from the device operated by the user, a request to engage in a voice conversation; responsive to receiving the request, accessing the phone number associated with the authorized device; and initiating a voice call session by placing a call, over the network, to the phone number associated with the authorized device.

There are provided systems and methods for automated data tokenization through networked sensors. A network of data sensors may detect that a user is likely to engage in electronic transaction processing with a merchant device, for example, based on an action performed by the user and/or with a user device. One or more of the sensors may connect with the user's device and retrieve financial data from the device and/or data necessary to issue a token to the device for transaction processing. The sensor may perform a background process to issue the token to the device, and once onboarded, may store the token to the user's device and/or the merchant device that the user is likely to interact with for transaction processing. The token may be limited in use by location and/or amount, or may be used to fully onboard the user with the token service provider.

Examples in this application disclose data verification methods, media, and systems. One example method includes receiving, from a blockchain network by a trusted execution environment (TEE) in a blockchain node, a trigger instruction based on a timed starting logic identifying a starting time to execute a smart contract, where the timed starting logic is comprised in a chain code which comprises information of a blockchain account and is executable by the blockchain node to determine the information of the blockchain account, retrieving first encrypted data from a first institution, decrypting the first encrypted data, receiving a data sharing request comprising a user identity corresponding to user basic data from a second institution, retrieving the user basic data based on the user identity, performing verification processing of the user basic data based on the trigger instruction to obtain a verification result, and sending the verification result to the second institution.

A system and method for third-party food and dining ordering control, comprising at least one device capable of accessing the internet which may be a mobile device or personal computing device such as a laptop or desktop, a web application, and a point-of-sale system at a restaurant or retailer, wherein users of the web application may deposit funds into an account and set regulations on what they may purchase with the deposited funds, or have an administrator set up an account for them such as a parent setting up an account for a child or a doctor setting up an account for a patient, allowing the parent or doctor or other administrator to regulate what the sub-user such as the child or patient may purchase, in keeping with budget, diet, and lifestyle restrictions, and which may utilize zero-step authentication to allow for seamless use of the service at certain establishments.

Secure authentication and delayed transaction processing for booking management systems is provided. Third-party services partner with booking management systems to aggregate and list offerings of the third-party services in a digestible display on a one-stop platform. A booking management system can manage the authentication of payment card information on behalf of any number of such third-party services. The booking management system can maintain and process authentication information associated with traveler payment cards, and provide virtual payment information to the third-party services for delayed transactions. The third-party services may later initiate the delayed transactions using the virtual payment information, without being required to perform authentication processing on the traveler payment card information maintained by the booking management system.

A method for limiting exposure to infectious disease by controlling access to a controlled access venue to admit individuals who have tested non-infectious for a particular highly infectious disease or have received a vaccination against the same comprises receiving, at a central website operator server, consumer user identification information from consumer users and storing that information in a consumer user database associated with the server. A biometric identifier from the consumer users is transmitted to the consumer user database and each associated with its respective associated consumer user to form an enrollment record. Identity of a presented individual is collected at a medical certification point and an authority record is created in an accessible authority database. At said medical certification point, an antibody test or vaccination is administered and the same is noted in the authority record. A biometric is collected from a venue presented consumer at a presentation venue, compared to authority records for a match, and the result provided to the venue.

A near-field communication (“NFC”) tag identifier (ID) associated with an establishment obtain by scanning an NFC tag at a location in the establishment using a wireless device of a patron is received. Login credentials associated with the patron and the wireless device are received. A location of the patron in the establishment is determined from the login credentials associated with the patron and the wireless device, and from the NFC tag ID. An available service of the establishment is communicated to the wireless device of the patron based on the login credentials associated with the patron and the wireless device, and from the NFC tag ID. The identified location is associated with exact order items so the service staff is able to keep track of an order made by the patron.
