Abstract: The purpose of the present invention is to propose a dual-channel identity authentication selection device, system and method. During payment or login, a security method is involved, where one channel is used to transmit a user name, and identity authentication data and devices are selected by a selection device according to the transformed user name, and the other channel is used to transmit the data to a server. When an insecure computer terminal is used, another computer terminal can be used to cooperate with a server to achieve secure payment or login. The method can be used for network payment, and can simply and securely solve the problems of identity authentication and payment data security in the process of using services of banks, games and the like by combining with a good cryptographic protocol.

Abstract: The invention discloses a computing system such as a computer, a Personal Digital Assistant, or a mobile phone, being connected both to an internal network and an external network and being able to quickly and safely switch therebetween without being shut down while ensuring a physical separation between the two networks. When a user inputs a request of switching, a switching unit will set a trigger thereof and generate a consequent non-maskable interrupt to CPU. After receives the NMI, the CPU controls the switching unit to run a switch program kept therein to back up a current status of the system. Then the switch program backs up a current status, controls the switching unit to interrupt all serving programs and loads the other status other than the current status to the computing system, and finally control the switching unit to reset the trigger.

Abstract: A device and method for computer display synthesis are provided. The device collects the display output information of each operation system; according to the content of each operation system display windows register, the device synthesizes the display information of each operation system to the corresponding windows for displaying, outputs the information to a screen, determines the position of the mouse on the screen, and sends the information to display synthesis control device; according to the present position of the mouse and the content of each operation system windows register, determines the operation system locates in which the mouse, connects the mouse and the present operation system, or clicks the mouse to confirm, and then connects with it.

Abstract: The invention presents an apparatus and method of realizing secured and compatible partition or absolute separation of multiple sections on a single hard disk for multiple OS as well as other software programs. One-way lockup device and set address lock device together constitute a complete and secured apparatus to separate OS and other software programs on a single hard disk. Furthermore, with hard disk reserved section, write-protection section in the front of hard disk, write-protection section at the back of hard disk, and hard disk Address Offset technology, it can realize secured and compatible absolute separation of multiple OS or software programs on a single hard disk with data exchange or one-way data exchange at the same time.

Abstract: The invention is an apparatus and methods realizing secured switch of computing system status. Explanatorily, the switch control unit responds to status switch requests and sends out NMI to CPU; CPU responds to the interrupt signals and processes secured switch control programs; through the stated switch control unit, the stated switch connection unit completes the switch connection alternatively to one of the two stated state save units; after processing the interrupt service program, the stated switch control unit notifies the stated CPU to resume the data stored in the alterable state registers of the computing system before the interrupt; thus the computing system can be safely switched between different operation systems, or internal and external networks.

Abstract: The present invention relates to a method and system for transferring property right from a property-right-transferor to a property-right-transferee. A property-right-changer makes a digital signature for the digital secrets of the property-right-transferor and the information related to the property right to be transferred, or makes a digital signature for the digital secrets of both the property-right-transferor and the property-right-transferee and the information related to the property right to be transferred, and generates a encoded-property-right which is then provided to the property-right-transferee. After verifying, the property-right-transferee provides a consideration to the property-right-transferor. Then, the property-right-transferor discloses his secrets to the property-right-transferee. The property-right-transferee submits the encoded-property-right to the property-right-changer and discloses all the secrets included in the encoded-property-right.
