A system for maintaining accurate health data and for providing rewards to data market participants. A marketplace platform based on Blockchain technology leverages smart contracts to provide rewards to sellers of data assets that provide corrections or updates to medical data, such as provider demographics. A URL API is provided to a buyer of the data with an encrypted password that is used to access the data from the URL API.

Methods and systems for micropayment support to blockchain-incentivized, decentralized data streaming and delivery are disclosed. To receive a blockchain-based payment for streaming a data resource to multiple users, a caching node first joins a payment-authorized peer group and is notified upon the creation of a micropayment pool. After delivering a portion of the data resource to each user, a service receipt signed by the recipient user is obtained, and submitted to a payment server together with a payment authentication certificate. An updated off-chain transaction is obtained from the payment server, for later submission to the blockchain to claim a total payment from the micropayment pool.

An online transaction with a merchant website is initiated and completed via a single input action by a user. An online transaction application retrieves a first portion of user credit card information from a first storage location and a second portion of the user credit card information from a second storage location, decrypts the first portion with a first decryption key and the second portion with a second decryption key, encrypts and temporarily stores the complete user credit card information, and publishes an order associated with user order information to a pub/sub message bus. In response to the order being published, a headless browser that is connected to the merchant website retrieves and decrypts the unified user credit card information; completes the merchant checkout process; and deletes, erases, or otherwise removes the temporarily stored complete credit card information.

A method for utilizing a registration authority to facilitate a certificate signing request is disclosed. In at least one embodiment, a registration authority computer may receive a certificate signing request associated with a token requestor. The registration authority may authenticate the identity of the token requestor and forward the certificate signing request to a certificate authority computer. A token requestor ID and a signed certificate may be provided by the certificate authority computer and forwarded to the token requestor. The token requestor ID may be utilized by the token requestor to generate digital signatures for subsequent token-based transactions.

Systems and methods for utilizing a mnemonic to communicate sensitive data to an agent are disclosed. In aspects, a computer-implemented method comprises: establishing a telephone connection between a caller and an agent; entering an encryption key received from the agent into a mnemonic application of the computer device to permute an algorithm of the mnemonic application; receiving sensitive data in the form of one or more alphabetic, numeric or alpha-numeric sequence; initiating the mnemonic application to generate a mnemonic of the sensitive data using the encryption key, wherein the mnemonic is a sequence of words representing the sensitive data; displaying the mnemonic to the caller; and conveying audio communication of the mnemonic to the agent through the telephone connection to enable remote decoding of the mnemonic back into the at least one sensitive number sequence.

A method of providing a payment system based on the unallocated gold transfer and digitally encrypted gold transfer between parties.

System methods and apparatus are disclosed for remote management of payment terminals. Public keys, or other security elements can be received from a certification authority and distributed to the payment terminals. A merchant, or other entity affiliated with the payment terminals, can monitor the status of the software and security elements of the payment terminals.

A validation system that includes a server and a validation terminal. The server is configured to receive location information for a mobile device and to determine the mobile device is at a registered location. The server is further configured to process a transaction for the products in a digital cart, to generate a barcode, and to encrypt the barcode using a private key linked with the registered location. The server is further configured to send the encrypted barcode to the mobile device. The validation engine is configured to scan the encrypted barcode using a barcode reader and to decrypt the encrypted barcode using the stored public key that is linked with the private key. The validation terminal is further configured to indicate the transaction is valid in response to decrypting the encrypted barcode using the public key.

Examples for enabling off-network transactions to be performed and securely managed are provided. An example system may include a data network, a digital ledger server, a blockchain platform, smart payment devices, and point of sale devices. Each respective point of sale device and each respective smart device may be operable to perform an off-network transaction, and store information related to the transaction in a digital ledger coupled to each respective device. When a transaction is executed between a POS device and a smart payment device, the POS device and smart payment device exchange a record of all off-network transactions that each respective device has executed since the last time a connection was made to the data network. When a network connection is established for each device, the respective information stored in the digital ledger is uploaded to the blockchain platform for storage and the digital ledger server for transaction resolution.

Techniques and apparatus for providing peer-based management of user accounts are described. In one embodiment, for example, an apparatus may include at least one memory and logic coupled to the at least one memory. The logic may be configured to determine a total entity risk value representing a risk position of an entity comprising at least one segment, generate a plurality of risk tokens, each of the plurality of risk tokens having a token value that is a portion of the total risk value, determine a total segment risk value for the at least one segment, the total segment risk value representing a portion of the total entity risk value allocated to the at least one segment, and distribute the plurality of risk tokens to the at least one segment of the entity to correspond with the total segment risk value. Other embodiments are described.
