摘要： A processing method and system of cloud broadcasting and printing data, relating to the field of information security. When receiving a service obtaining request, a server processes first data in the service obtaining request into printing and broadcasting data, processes the printing and broadcasting data into first verifying data and then sends the first verifying data to a cloud broadcasting and printing service platform. The cloud broadcasting and printing service platform processes the first verifying data into second verifying data and then sends the second verifying data to a cloud broadcasting and printing all-in-one machine. The cloud broadcasting and printing all-in-one machine processes the second verifying data into printing and broadcasting data, and extracts printing information and broadcasting information from the printing and broadcasting data at a time and performs broadcasting and printing respectively.

摘要： A method for secure interaction on a universal platform. The method comprises: when a verification code needs to be inputted, a universal platform transmits a switching notification to a security chip via a secure interface; when the security chip receives the switching notification, same controls a switching circuit to switch a touch input module and a display module to be controlled by the security chip, controls the display module to prompt a user to input the verification code, controls, on the basis of coordinate data, the display module to generate and display a keyboard, acquires from the touch input module verification code coordinate information generated by the touch input module on the basis of screen-touching information of the user, produces the verification code on the basis of the verification code coordinate information and of the coordinate data, encrypts the produced verification code to produce a verification code ciphertext, outputs the verification code ciphertext via a preset interface, and controls the switching circuit to switch the touch input module and the display device to be controlled by the universal platform. The present invention prevents losses incurred by a verification code leakage.

摘要： A method and apparatus for measuring the remaining power level of a device. The state of flag bits are detected, a password is calculated when a first flag bit is set, the password is displayed to reset the first flag bit, and the detection of the state of the flag bits is returned to; the total power consumption is calculated when a second flag bit is set, the remaining power level is updated on the basis of the total power consumption and of a second preset value, the second flag bit is reset, and the detection of the state of the flag bits is returned to. The present invention implements increased precision in measuring the remaining power level without additional component, accurately reflects the actual value of the remaining power level of a battery, and incurs no additional power consumption. This does not affect the service life of the device and is inexpensive.

摘要： A working method of an NFC dynamic token, comprising the following steps: after detecting that a preset press key is triggered, the NFC dynamic token activates NFC communication and builds connection with a mobile device via NFC channel; when the NFC dynamic token receives a second instruction from the mobile device, the NFC dynamic token obtains a seed key from the second instruction, stores the seed key and sends a message that writing is successful to the mobile device; when the NFC dynamic token receives a third instruction from the mobile device, the NFC uses self-stored seed data to generate a dynamic password and sends the dynamic password to the mobile device via the NFC channel. According to the present invention, the seed key is written into the NFC dynamic token via the NFC channel, which improves security and flexibility of the dynamic token.

摘要： A working method for an IC card having a fingerprint recognition function, comprising: an IC card receiving and determining an instruction type from a terminal, and when determined that the received instruction is an application selection instruction, the IC card selecting an application and returning a response to the terminal; when determined that the received instruction is a processing option acquisition instruction, the IC card acquiring a user fingerprint information verification state according to the content of the instruction, and if verification is successful, returning to the terminal a processing option instruction response containing an application file locator list for which a personal identification number does not need to be verified; if verification fails, returning to the terminal a processing option instruction response containing an application file locator list for which a personal identification number must be verified; when determined that the received instruction is a record reading instruction, the IC card returning a record reading response to the terminal according to the record reading instruction, wherein the record reading response contains a method for verifying a card holder. Thus, the risk of a personal identification number being leaked is avoided, thus enhancing the security of a transaction, while also improving user experience.
