摘要： The present invention provides a resource file processing method based on a blockchain structure. The method includes a member node in a blockchain including at least one supervision node and at least one member node constructs a resource file registration request according to a user instruction, and sends the resource file registration request to one of the at least one supervision node. According to the resource file registration request from any member node, the at least one supervision node audits and registers a resource file indicated by the resource file registration request, and transmits the registration result back to the member node initiating the resource file registration request. The at least one member node performs an operation on a real physical resource associated with the registered resource file by performing data communication with another member node.

摘要： A non-contact communication method and a communication device are presented. The communication device includes a trusted execution environment (TEE). A first security application and a second security application are provided in a security element of the communication device. The first security application and an application in the trusted execution environment are communicationally connected by means of a first communication channel. The second security application and a near-field communication (NFC) module provided in the communication device are communicationally connected by means of a second communication channel. The first security application and the second security application are communicationally connected by means of a security channel. Using the non-contact communication method and the communication device, a security channel may be established between NFC and a TEE, which may enable NFC non-contact card reading for a TEE application.

摘要： The invention relates to a data processing method and a system based on NFC tag. The method comprises: acquiring amount data; generating custom order number for identifying a transaction; issuing tag data application request based on original NFC tag data, acquired amount data and custom order number; generating updated NFC tag data based on tag data application request and saving custom order number, and setting payment state for custom order number to be the unpaid state; updating the NFC tag based on the updated NFC tag data to obtain an updated NFC tag, wherein the updated NFC tag includes amount data; and reading the updated NFC tag and completing payment processing based on updated NFC tag. According to embodiments of the invention, it does not require transaction amount to be input by the user's mobile phone terminal, but instead, transaction amount is obtained by tag receiving terminal through input device.
