A method and system is used in transferring the real right. The real right cashing person makes digital signature for the digitized secret of the real right transferring person and information about the real right to be transferred, or for the digitized secret of both the transferring person and the accepting person and information about the real right to be transferred, and then generates the cipher real right and supplies it to the accepting person. The accepting person validates it and then supplies the corresponding price to the transferring person. Then the transferring person discloses all the secrets. The real right accepter submits the cipher real right to the cashing person and discloses all the secrets in the cipher real right. The cashing person validates it and then cashes the real right for the accepting person.

A hard disk read and write capability table is generated by a secure application software at the start-up of the computer for indicating the read and write capability of each sector of the hard disk, and this table is stored in a secure memory. During a hard disk read or write operation, the computer issues a request to a chip having computing ability, the legality of this read or write request is determined by the chip based on the hard disk read and write capability table, thereby, a hard disk read and write control circuit is controlled to allow or inhibit the execution of this read or write operation. This method and apparatus can effectively prevent the spread of computer viruses, so as to protect the files and data on hard disk from damages, alterations and illegal uses.

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.

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. Then, after verifying, the property-right-changer shall transfer the property right to the property-right-transferee.

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.
