Abstract: 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.

Abstract: 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.
