Abstract: In some examples, a first computing device receives, from a second computing device, a security certificate of the second computing device. Based on receiving the security certificate from the second computing device, the first computing device stores the security certificate in a data structure and causes a security layer of the first computing device to receive the security certificate. The security layer may implement a network security standard to communicate with the second computing device based at least on receiving the security certificate. Additionally, the first computing device transmits the security certificate stored in the data structure to a validation system to determine a validity of the security certificate.

Abstract: Disclosed are various embodiments for efficiently creating non-fungible tokens. A smart contract can receive a non-fungible token (NFT) creation request that specifies a number of non-fungible tokens (NFTs) to create. The smart contract can then create a plurality of NFTs equal to the number of NFTs specified in the NFT creation request. The smart contract can subsequently assign each of the plurality of NFTs to a blockchain address. Finally, the smart contract can store, in a single operation, the plurality of NFTs to the blockchain.

Abstract: Disclosed is a conversation management system that manages conversations about a content using blockchain technology. The content management system can use the blockchain technology to validate the conversations, and provide a content provider of the content a secured access to the validated conversations. The validation of the conversations can ensure that the conversations are not fake, e.g., provided by real people and not generated using bots. A conversation about the content is added as a block to the blockchain upon validation, and once added may not be modified, and therefore, the content provider may be assured that the conversation is secure and genuine. The content provider can use the knowledge obtained from the validated conversations in making future content.

Abstract: Payment systems and methods that facilitate electronic payer-payee financial transactions, using one or more universal payment identifiers, are disclosed. One method includes a payer computing device receiving a payment credential associated with a payee. The payment credential may be mapped to a universal payment address. The payer computing device may request a payment server for a payee account information associated with the payment credential. The payment server may translate the payment credential to the universal payment address, resolve the universal payment address to the payee account information, retrieve the payee account information using the universal payment address, and transmit the payee account information to the payer computing device. The payer computing device may perform a payment PUSH operation to the payment server. The payment server may forward the payment PUSH operation to the payee account to complete a financial transaction between the payer computing device and the payee.

Abstract: Methods and systems are presented for providing a framework for facilitating time-sensitive cryptocurrency transactions for users. When a request for processing a time-sensitive cryptocurrency transaction using funds from a cryptocurrency wallet is received from a user, a transaction system first verifies whether the cryptocurrency wallet has a balance to cover the cryptocurrency transaction. The transaction system also verifies the ownership of the cryptocurrency wallet based on an asynchronous method. The user generates verification data without any input from the transaction system, and based on a private key associated with the cryptocurrency wallet, a generator function, and a user-generated value. Without knowing the user-generated value, the transaction system verifies the ownership of the cryptocurrency wallet based on the verification data, and processes the transaction for the user.

Abstract: Example apparatus and methods facilitate providing an incremental future-proof license to a master stream of content. The master stream may be related to different instances of content (e.g., different versions) for which there is a unified content representation. A request for content available through the master stream may be received from a licensee. The request may include an explicit indication of which stream of frames is to be accessed or may include implicit information from which a stream of frames may be selected. The selected stream may be changed midstream in response to changing conditions (e.g., bandwidth), events (e.g., gesture), devices (e.g., licensee accesses different device) or explicit requests. As the available streams of frames associated with the content changes, the changes may be mapped to the master stream and made available to the licensee. The licensee may pay an incremental license fee for access to updated content.

Abstract: Various embodiments are generally directed to autofilling card data from a contactless card to a form of a computing device. An application may determine that a payment field of a form has received focus. The application may then receive encrypted data from a communications interface of a contactless card associated with an account. The application may then receive, from a server, verification of the encrypted data. The application may then receive, from the server, an encrypted account number associated with the account, and decrypt the encrypted account number to yield the account number. An autofill service of an operating system (OS) executing on the processor circuit, may then autofill the account number to the payment field of the form.

In embodiments, the present invention relates to specific applications of fiat-backed digital assets and/or stable value digital asset tokens tied to a peer-to-peer network, such as a blockchain network.

Abstract: An electronic data protection (EDP) computing device for protecting sensitive data of a user during a computer interaction between the user and a business entity computing device associated with a business entity is provided. The EDP computing device is configured to receive interaction data for the computer interaction from the business entity computing device. The interaction data includes an interaction identifier, a business entity identifier, and a user identifier in lieu of a protected data object. The EDP computing device generates a token request message using the interaction data and a request token and transmits the token request message to the user computing device, prompting the user to pick a user account. The EDP computing device receives a response token identifying an account selected to complete the computer interaction, retrieves the protected data object, and completes the computer interaction using the protected data object.

Abstract: The invention relates to systems and methods for distributing encrypted market data updates to market participants via private multicast channels. Among other factors, characteristics of modern computer networks may cause participants to be sent (and to receive) their encrypted data for that update at different times. Thus, after the participants have all been sent their data for that update the system may then simultaneously transmit to those participants the key that will enable them to decipher their data via a public multicast channel such that all recipients receive the key at the same time. In this manner the invention may ensure that although participants receive their data in a given update at different times, they are unable to decipher that data until substantially the same time.

Abstract: A system for extending the utility of blockchain environments when such environments become too large or complex, is disclosed. The system systematically creates a second generation, or child blockchain that can retain machine-readable links to the parent blockchain which, in turn, can be archived and referenced, when necessary, for historical reference. Accordingly, the system serves to reduce the size of the working blockchain thereby making it easier to store the blockchain, and further serves to increase the speed of queries to interrogate the current state of the blockchain. By reducing the size of the working blockchain, the present invention seeks to extend the utility of large blockchains by segregating and archiving historical or older transactions recorded in the blockchain. The system and process further include methodologies to create links between the current blockchain and the archived sections of the blockchain to ensure the integrity of the full historical ledger.
