In this way, unique profiles can be created and shared in real time while maintaining confidentiality of health records and more as relates to providing the implementation of control measures to protect workers from identified occupational health hazards. The system relates generally to a system and method to characterize risk of occupational health hazards and implement control measures to protect workers, with real time evaluations of environmental conditions and exposure concentrations, and platform for use are disclosed herein. Furthermore, the system relates to providing a system and method for characterizing the risk of various occupational health hazards across various industries, implementing and providing control measures that can be adopted to protect workers in such hazards or situations in real time.

Systems and methods are provided for processing objects. For example, a call request message is received, the call request message carrying an identification (ID) of order data associated with one or more objects, the order data including at least a total value of the objects and an ID of a second subject; a first account related to a first subject and a user password related to the first subject are acquired; the first account and the user password and the ID of the order data are sent; the first account and the user password and the ID of the order data are forwarded; and based on at least information associated with the first account and the user password and the ID of the order data, the total value is deducted from a first value included in the first account related to the first subject.

Disclosed herein is a method and system to establish a secure communication channel between a payment object reader and a payment terminal For this, the server determines whether a payment terminal has associated with an attestation ticket. The method further includes determining, whether to approve or deny the request for establishing the secure communication channel between the payment object reader and the payment terminal based on the attestation ticket. If the determination yields that the request has been approved, further generating a session approval interrupt having one or more session approval conditions; and sending the session approval interrupt to the payment terminal, where the session approval interrupt causes a secure communication channel to be established between the payment object reader and the payment terminal.

A method including receiving, by a server computer, a request message from a token requestor computer on behalf of a user device. The request message comprising a first current token tracking value and a first function index value. The server computer can determine a second function index value. The server computer can then compare the first function index value to the second function index value. If the first function index value and the second function index value match, the server computer can determine a function based on the first function index value and a stored function table associated with the user device. The server computer can then determine a second current token tracking value based on the function, then compare the first current token tracking value to the second current token tracking value. The server computer can generate a response message in response to the comparing.

Systems and methods for facilitating transfer of ownership of tokens between users on a decentralized database stores a registry of assets and transactions are disclosed. Exemplary implementations may: store, on electronic storage, a set of code executable by the decentralized database to manifest individual tokens on the decentralized database; and record the set of code on the decentralized database such that the set of code is accessible at a creator address that is associated with the creator of the set of code. Using the functions defined by the set of code, an owner of an individual token can offer to sell the individual token, and a buyer can accept this offer to buy the individual token, at an agreed-upon price.

Various examples are directed to secure communications for mobile wallet applications. A first mobile wallet application may send a content request describing a first offering to a wallet management system. The first mobile wallet application may receive from the wallet management system first merchant web content describing the first offering. The first merchant web content may be verified by the wallet management system and may comprise first address data describing a first address of a first merchant payment gateway. The first mobile wallet application may send payment data to the first merchant payment gateway at the first address. The payment data may indicate a payment amount for the first offering.

A block packaging method based on blockchain transaction is used in an electronic device. The electronic device controls each node in the blockchain to receive and store a blockchain transaction, and calculate a hash value of the each node according to the blockchain transaction, generate a package voting information according to the hash value of the each node, and send the package voting information to a voted node. The electronic device further controls the each node to record the number of votes as the voted nodes according to the package voting information to obtain the number of votes of the each node, take the node with the largest number of votes as a target node according to the number of votes, and pack the blockchain transaction into blocks and broadcast the blocks to all nodes in the blockchain.

A method for selling a cryptocurrency via a consumer-operated kiosk is provided. In some embodiments, the method: displays to a user, via a user interface, one or more options to purchase one or more cryptocurrencies; receives from the user, via the user interface, a selection of one of the cryptocurrencies; obtains a cryptocurrency exchange rate from a cryptocurrency exchange; presents the exchange rate to the user via the user interface; receives from the user payment for the selected cryptocurrency via a bill acceptor; purchases the selected cryptocurrency from the cryptocurrency exchange in an amount based on a value of the received payment and the exchange rate; and displays to the user, via the user interface, a receipt having a redemption code and a personal identification number (PIN), wherein both the redemption code and the PIN are necessary to obtain the selected cryptocurrency.

Disclosed is a value transfer system based on the Domain Name System (DNS) including: a fund management server, leveraging network protocols to transfer value that includes, but not limited to, digital currency and electronic currency; a DNS server, configured with a resource record that has a mapping relationship to the IP address of a fund management server, wherein when a client queries the resource record through the DNS server, the DNS server resolves the resource record to obtain the IP address of the fund management server and feeds the IP address back to the client so that the client interacts with the fund management server according to the IP address to perform the corresponding value transfer. A user can perform cross-platform remittance directly via a wallet address or an e-mail address related to a domain name, thereby greatly improving the reliability and efficiency of remittances/receipts. Since each of the domain names has WHOIS records containing real information and data of the domain name owners, registrars, and the relevant personnel, real-name authentication can be achieved through remittances by wallet or email addresses bound to the domain names, thereby obtain necessary legal support and supervision.
