A system and method for managing a plurality of network-enabled client devices such as Internet of Things (IoT) and smart devices employs a distributed ledger or blockchain to store security-related information for each client device. Access to the distributed ledger is provided through a proxy computing system that is configured to exchange security-related messages with the client devices over a first communication path, which may be over a public network; and to engage in transactions with or query the distributed ledger on behalf of the client devices over a second communication path, which is a private channel Vendible data published by the client devices may be routed by the proxy computing system to a data broker or publishing system in a manner that removes identifying information from the vendible data.

A system, method and computer program product for computer based open innovation, includes an asset valuation device receiving asset information regarding tangible or non-tangible assets, and generating a valuation signal, based thereon; a self-executing code device receiving the valuation signal, and generating a self-executing code signal, based thereon; an air router device having both low band radio, and internet router channels for redundant internet communications, and a malicious code removal device for scrubbing malicious code from data received, receiving the valuation signal, and generating a node voting request signal, based thereon; a mesh network having node devices receiving the node voting request signal, and generating vote confirmation signals, based thereon; and computing devices connected to each of the respective node devices, and configured to perform non-fungible token (NFT) generation based on the assets, including tracking respective ownership and valuation of the assets, based on the asset information.

A decentralized and trust-minimizing computer architecture for computing rewards for users of an advertising system includes cryptographic black box accumulators (BBA), which is a cryptographic counter that only the issuer can update. An attention application requests initialization of a BBA from a guardian and subsequently requests updates to the BBA to track interactions between a user of the attention application and ads on the attention application. The guardian signs updates to the BBA to reach agreement on the state of ad interactions. The attention application may randomize the BBA and submit requests via an anonymous channel such that no participant can link two encounters with the BBA to each other or link the BBA to a specific attention application, thus improving user privacy. Reward redemption requests can be made based on a known policy and committed to a public blockchain for verification by observers that the protocol is operating correctly.

A method, apparatus, and system of activating and using a contactless card are disclosed. A mobile device includes a wireless chip structured to allow short-range wireless communications (e.g., a near-field communication), a processor, and a memory storing instructions. The mobile device is configured to communicate with a contactless card via a short-range wireless communication and receive a customer-specific uniform resource locator (URL) from the contactless card via a wireless chip. In response, the mobile device is configured to automatically open a web browser and navigate to a website associated with the customer-specific URL. The customer-specific URL identifying the client associated with the contactless card. The mobile device then prompts, via a GUI on the display, a user for authentication information, and based on a verification of the authentication information, display a confirmation page indicating activation of the contactless card.

A computing system may receive a request of the user for a first action of the user with an entity. In connection with granting the request of the user, the computing system may configure a token for use by the user and the entity such that (i) the entity is added as an approved entity, and (ii) the token is configured with a resource amount of the first action as a usage threshold of the token. The computing system may receive a request of the entity to use the token. The computing system may determine whether granting the request of the entity would cumulatively exceed the usage threshold of the token. Based on a determination that granting the request of the entity would not cumulatively exceed the resource usage of the token, the computing system may grant the request of the entity to use the token.

A system for preventing or inhibiting Payment Card fraud. When a Payment Card transaction is initiated, the card network conveys cardholder identifying information to the bank that issued the Payment Card. The issuing bank generate a random, one time data code (OTDC) upon receipt of cardholder identifying information. Alternatively, the cardholder may request an OTDC, by directly messaging the issuing bank or via an automated communication between the cardholder's mobile device and the issuing bank. The issuing bank then sends the cardholder an OTDC, preferably via an encrypted, secured transmission. The cardholder provides the OTDC to the merchant. The OTDC is part of the issuing bank's transaction approval criteria. The transaction should not be approved unless the merchant provides the OTDC to the issuing bank. The OTDC will only work for the transaction in question, and it will preferably expire shortly after its generation, if it remains unused.

Systems and methods for secure resource management are provided. A secure resource management system includes a resource record repository, such as a secure database or a blockchain, for storing resource records for resources. The resource records contain information of resource providers, information of resource users having a right to obtain resources, and resource transaction histories. Responsive to a request to verify an authorized user of a resource, the secure resource management system further queries the resource record repository, retrieves the resource record, determines the resource user currently having a right to obtain the resource as the authorized user of the resource, and transmits the verification result in response to the request. The verification result identifies the authorized user of the resource and can be used to grant access to the resource by the authorized user.

Example embodiments relate to performing activation techniques for contactless cards. For example, embodiments may include performing a near-field communication (NFC) exchange with a contactless card, processing a message comprising data to activate the contactless card, communicating the data to a server to activate the contactless card; and receiving a response from the server, the response to indicate whether the contactless card is successfully activated or not successfully activated.

A method and system are provided to support a decentralized distributed ledger in which transactions are recorded by parties to the transactions without the use of a blockchain. A distributed ledger system provides a protocol framework that supports the development of protocol flows. A protocol flow is computer code that controls the performance of a transaction by the party or parties to the transaction. Protocol flows can be developed for different types of transactions. The distributed ledger system allows transactions to be proposed, accepted, and notarized by a notary and stored without the use of a blockchain ledger. The distributed ledger system can avoid the expense of the computational and storage resources needed to redundantly verify a transaction and store evidence on the many nodes of a blockchain distributed ledger.

This disclosure provides techniques for recovering a root key from measurement of a circuit function. In some embodiments, a checkpointing feature is used to periodically mark measurements of this function and thereby track drift in the value of the root key over the life of a digital device; the checkpointing feature permits rollback of any measurement of the function in a manner that negates incremental drift and permits recovery of the root key for the life of a device (e.g., an IC circuit or product in which the IC is embedded). This disclosure also provides novel PUF designs and applications.
