Abstract: A system includes an image capturing device, a subject reference marker disposed adjacent to a subject, a tool reference marker disposed on a treatment tool, a display device mounted on an operator, an operator reference marker disposed on the display device, and a processor. The image capturing device includes two image capturing modules that simultaneously and respectively capture two images of the operator, the subject, and the treatment tool. The processor receives the images, analyzes the images to obtain spatial locations of the reference markers, and transmits coordinate information and auxiliary information.

Abstract: In a proposed surgical navigation method for a surgical operation to be performed on an operation target, a mobile device stores 3D imaging information that relates to the operation target before the surgical operation. Then, an optical positioning system is used to acquire spatial coordinate information relating to the mobile device and the operation target, so that the mobile device can obtain a relative coordinate which is a vector from the operation target to the mobile device, obtain a 3D image based on the relative coordinate and the 3D imaging information, and display the 3D image based on the relative coordinate, such that visual perception of the operation target through the mobile device has the 3D image superimposed thereon.

Abstract: A network reputation system and its controlling method are provided. A credential and exchange component permits a user to generate credentials and exchange matching items with those persons having a social relationship with the user. A reputation evaluation component enables other users to make evaluations about an estimatee via the sharing of social network information. A query and response component receives a query from a person having a social relationship with the user for requesting an evaluation about the estimatee, and responds with an associated evaluation result to the person having a social relationship with the user, via the sharing of social network information and the evaluations made by the other users about the estimatee.

Abstract: A biometric method, a biometric apparatus, and a biometric data encryption method thereof are disclosed. In the biometric method and the biometric apparatus, a biometric data is quantified to obtain a quantified data. A one-way function is then performed to convert the quantified data into an encrypted data. In the present invention, the biometric data is protected through a cryptography system so as to prevent the biometric features from being stolen or misappropriated. Moreover, in the present invention, a biometric technique can be integrated with a cryptography technique.

Abstract: An authentication system for a wireless network is disclosed. The authentication system includes a card, a card reader, an end-user device, and a wireless access device. The card reader is coupled to the wireless access device. The card records a data, and the card reader reads the data recorded in the card. The wireless access device receives the data read by the card reader and performs authentication between the wireless access device and the end-user device according to the data.

Abstract: A handover authentication method includes performing, by a wireless network server, a first authentication between a client and the wireless network server via a first network gateway; obtaining first authentication keys for the wireless network server and the client based on the first authentication; determining, by the wireless network server, a need to handover the client from the first network gateway to a second network gateway; deriving, by the wireless network server and from the first authentication keys, a handover authentication key shared by the client and the wireless network server; obtaining, by the wireless network server, second authentication keys for the network server and the client; and serving, by the wireless network server, the client via the second network gateway.

Abstract: Disclosed is a computerized apparatus and method for version control and management. The apparatus includes a cryptography boot loader, a control module on key usage, and one or more agents. After the user's device is powered on, the cryptography boot loader stores a user key, and checks an operating system (OS) certificate for an OS and an application certificate for an application to determine whether these certificates are valid. Then, a right object is obtained with a user certificate through an agent. The control module on key usage compares the OS version and the application version with the version required by the right object. The permission access to the user key is determined by the comparison result. This invention associates the cryptography component with the boot loader to develop a security mechanism performed by OS and application for using a secret key.

Abstract: A web transaction system and a controlling method thereof are provided. The controlling method of web transaction system includes the following steps. The translating information of a temporary unit is provided to a first service unit by a web transaction system. Whether the temporary unit has received a first transaction element of the first service unit is determined. The translating information of the first service unit is provided to a second service unit. Whether the first service unit has received a second transaction element is determined. If the first service unit has received the second transaction element and the temporary unit has received the first transaction element, then the first transaction element is sent to the second service unit from the temporary unit.

Abstract: Provided are a wireless network management system and a method thereof based on a positioning system. By the positioning system, whether there are available wireless access points (WAPs, or APs) at the vicinity of a communication device is identified, so the communication device needn't hold the search for the APs and the power thereof is saved. Besides, by path programming, the possible path of the communication device is known and the next available AP for wireless communication is identified, so the communication to the current AP can be quickly switched to the next AP if necessary.
