A method and system for authenticating a service to access data respective of a user on a low-end mobile device. The method includes sending, from a telephone-to-web adapter, a first authentication token over a first communication path to the low-end mobile device, wherein the telephone-to-web adapter is a separate entity from the low-end mobile device; receiving, at the telephone-to-web adapter, a second authentication token over a second communication path, wherein the second authentication token is received from a host server hosting the service, wherein the first communication path is performed with a first method of communication and the second communication path is performed with a second method of communication; comparing, at the telephone-to-web adapter, the first authentication token to the second authentication token; and allowing access to data upon determining that the first authentication token matches the second authentication token.

An identification system uses a local cache for performing identifications. An identity system device may store identity information and identification information. An electronic device stores a cache of a portion of the identity information and a part of the identification information. The electronic device receives user input, determines an identity by comparing the user input to the cached identification information (such as by comparing a received digital representation of a biometric with cached biometric identification information), and performs an action using information in the cached identity information that is associated with the identity. The electronic device may update the identity information stored by the identity system device based on the action.

Methods and systems for processing a blockchain comprising a plurality of immutable sales records corresponding to sales made by agents of an entity are provided. According to certain aspects, a transaction request indicating a sale made by an agent of the entity may be received at a first node. A block including a sales record indicating the sale made by the agent may be added to a blockchain and transmitted to another node for validation. The first node may add the block to a copy of the blockchain, where the block may be identified by a hash value that references a previous block in the blockchain that includes at least one additional sales record.

A method for processing offline cryptocurrency transfers includes: receiving, by a receiver of a computing device, a first transfer message, wherein the first transfer message is cryptographically signed using a first private key of a first key pair; validating, by a processor of the computing device, the cryptographic signature of the first transfer message using a first public key of the first key pair; storing, in a memory of the computing device, the validated first transfer message; receiving, by an input device of the computing device, a transfer instruction, the transfer instruction including at least a communication address; and electronically transmitting, by a transmitter of the computing device, the validated first transfer message to an external device based on at least the communication address.

In one embodiment, a customer authentication system includes at least one sensor configured to provide location information of people around a product display section. A customer authentication device is configured to provide customer identification information. A processing device is configured to perform location tracking of the people around the product display section based on the location information from the one or more sensors. The number of people in a predetermined area around the first customer authentication device is then determined based on the location tracking. The processing device enables customer authentication via the customer authentication device if only one person is in the predetermined area and disables customer authentication via the customer authentication device if more than one person is present in the predetermined area.

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.

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.

An apparatus with a solid state drive (SSD) having an internal host to control proof of space activities. The SSD has a host interface configured to receive at least read commands and write commands from an external host system. The SSD has memory cells formed on at least one integrated circuit die, and a processing device configured to control executions of the read commands to retrieve data from the memory cells and executions the write commands to store data into the memory cells. The internal host operable is to generate, independent of the external host system, commands related to proof of space, such as plot generation, and plot farming.

Novel technical ways of facilitating secured execution of blockchain transactions are presented. In various embodiments, a system, comprises a non-transitory memory comprising instructions; and one or more hardware processors coupled to the non-transitory memory and configured to read the instructions to cause the system to perform operations comprising: detecting a request from a first user to access one or more digital assets of a first digital wallet of a second user; in response to detecting the request, determining whether to provide access to the one or more digital assets to the first user based on one or more factors, wherein the one or more factors includes a location of the first user, a location of the second user, or one or more characteristics of the first user; and restricting the first user from accessing the one or more digital assets based on the one or more factors.

A computer-implemented method of providing payment methods for an online transaction includes: receiving an unencrypted shopper identifier credential that is associated with a specific user and is input via a checkout user interface, wherein the checkout user interface is associated with the online transaction and is displayed at a user device; in response to receiving the unencrypted shopper identifier credential, generating a first encrypted shopper identifier credential based on the unencrypted shopper identifier credential; sending a first query that includes the first encrypted shopper identifier credential to a first payment instrument manager, wherein the first query requests an indication that the first encrypted shopper identifier credential is associated with an account for the first payment instrument manager; receiving a response from the first payment instrument manager that includes the indication; and causing the checkout user interface to be modified with a selection field, wherein the selection field is associated with the first payment instrument manager.
