A system for managing and using digital financial assets, such as cryptocurrency uses multiple independent devices that mutually cooperate to control cryptocurrency assets in a secure manner. Each of these devices may store a unique private key associated with the cryptocurrency assets, which may be configured such that a certain minimum number of these private keys are required to transfer the cryptocurrency assets. The use of multiple private keys spread across multiple distinct devices may reduce the likelihood of loss stemming from a hardware failure or reduce the likelihood of an attacker successfully gaining access to the cryptocurrency assets. In addition, selection of the devices to be used for storing these private keys, as well as how many private keys are required to authorize a transaction, may be tailored to balance a user's preferences for reliability of access versus security and for third-party custody versus self-custody.

A method for communicating information relating to test results of a user includes obtaining test results of a user. An assertion is derived from the test results of the user. The test results are input to a pre-provisioned first algorithm. The assertion is encapsulated in a first data object by a PGE that controls an environment in which the first algorithm is executed. A first proof is generated which is configured to be usable to verify that the first algorithm used the test results to produce the assertion when provided to a PVE along with the first data object. The test results itself are excluded from the first proof and the first data object such that privacy of the test results is maintained. The first proof and the first data object are communicated to a receiving communication device from an enterprise communication device associated with the user and an enterprise.

A method for touchless communication between an ATM and a smartglasses device worn by a user is provided. The method may be executed at the smartglasses device. The method may include identifying a current global positioning system (“GPS”) location of the ATM. The method may include communicating with an external database to determine an ATM identifier associated with the ATM. The ATM identifier may include ATM communication data. The method may include transmitting an external smartglasses identifier to the ATM via the ATM communication data. The method may include receiving a communication from the ATM. The communication may include an interactive payment interface. The method may include displaying the interactive payment interface on the smartglasses. The method may include receiving one or more commands from the user. The method may include transmitting the one or more commands from the smartglasses to the ATM.

A system for access control includes an interface to receive an access request from a first user application for permission to access a first digital identity wallet application and a processor to: determine whether to grant access for the first user application to the first digital identity wallet application, wherein access is granted for the first user application to the first digital identity wallet application in response to the first user application belonging to a first circle of trust and the first digital identity wallet application belonging to the first circle of trust; and in response to determining to grant access for the first user application to the first digital identity wallet application, provide an access granting indication.

A system and method provide efficient, secure and highly reliable authentication for transaction processing and/or access control applications in which only biometric input is required from the user. A Personal Digital Key stores a biometric profile that comprises a representation of physical or behavioral characteristics that are uniquely associated with an individual that owns and carries the PDK. The PDK wirelessly transmits the biometric profile over a secure wireless transaction to a Reader for use in a biometric authentication process. The Reader compares the received biometric profile to a biometric input acquired at the point of transaction in order to determine if the transaction should be authorized.

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.

An apparatus for validating an identity of an individual based on biometrics includes a memory and a processor operatively coupled to a distributed database and the memory. The processor is configured to provide biometric data as an input to a predefined hash function to obtain a first biometric hash value. The processor is configured to obtain, using a first pointer to the distributed database, a signed second biometric hash value. The processor is configured to define a certification of the biometric data in response to verifying that a signature of the signed second biometric hash value is associated with the compute device and verifying that the first biometric hash value corresponds with the second biometric hash value. The processor is configured to digitally sign the certification using a private key associated with the processor to produce a signed biometric certification and store the signed biometric certification in the distributed database.

This specification techniques for sharing service and identity information between devices. One example method include acquiring, by a first device, a digital object identifier (DOI) of a second device, the DOI including identity information associated with the second device; generating, by the first device, a service DOI based on the identity information from the DOI of the second device, the service DOI including the identity information of the second device and service information; and displaying, by the first device, the service DOI on a display of the first device, wherein the displayed service DOI is configured to cause the second device to perform service processing when the displayed service DOI is acquired by the second device, and wherein the service processing is based at least in part on the identity information and the service information included in the service DOI.

A payment method, apparatus, and device are provided. The method includes: determining, according to geographical location information of a user, a third-party payment institute corresponding to the user's location, obtaining, through a payment server, a payment account of the third-party payment institute compatible for a local transaction, and scanning a barcode to complete a payment using the payment account. During the payment process, a DOI including information of the payment account is presented to a merchant, and the merchant extracts the payment account therein, and forwards order information and the payment account to the third-party payment institute. The third-party payment institute identifies the payment account and forwards the same to the payment server. The payment server identifies a user identity corresponding to the payment account, and then completes the payment process.

This disclosure is directed to an item-identifying cart that may be utilized by a user in a materials handling facility to automatically identify items that the user places in their cart, and update a virtual shopping cart to include items taken by the user. The mobile cart may include four capture assemblies that are disposed proximate to each of the four corners of a basket of the cart, and oriented such that their respective optical axes are directed towards an interior of a perimeter of the top of the basket, and above the top of the basket. The capture assemblies may include proximity sensors that are used to detect movement above the top of the basket, LEDs that illuminate items, and cameras that generate image data representing the items as they are placed in, or removed from, the cart.
