    Abstract: An application-based data encryption method implemented in an operating system. When receiving system calls for writing data opened by an application, the operating system encrypts the data utilizing an encryption key. When receiving system calls for reading data requested by the application, the operating system decrypts the data utilizing a decryption key. The encryption key and the decryption key may be the same key or two different keys.

    Abstract: A user is provisioned for a Web service by supplying a user name and password. A digital certificate and VPN identifier are generated and downloaded to the user's computer. The VPN identifier and user identifier are stored into a database. The user accesses the Web service and establishes a VPN using the certificate and VPN identifier. A user identifier, user name or user password is not required. A gateway computer uses the VPN identifier to access the database previously established during the provisioning session to retrieve the user identifier. Retrieval of the user identifier validates that the computing device is authorized to use the Web service. The gateway computer stores the client IP address and a mapping to the user identifier into a database. A proxy server retrieves the user identifier from the database using the IP address and includes the user identifier in Web traffic for a remote computer.

    Abstract: A web application execution method, for a client to execute a web application on a remote server is provided. A connection status between the client and the remote server is monitored. If the connection is established, an online learning process is performed to monitor the handshakes between the client and the server, thereby constructing a virtual server. If the connection is disconnected, an offline service is activated, allowing the client to execute the web application through the virtual server. If the connection is reestablished after being disconnected, a synchronization process is performed to synchronize state machines within the virtual server and the server.

    Abstract: A crawling system crawls a web site initially in a pattern detection phase and subsequently in a pattern usage phase. The pattern detection phase attempts to identify patterns of references to pages that contain informational content of interest and patterns of references to pages that contain little informational content of interest. During the pattern usage phase, the crawling system crawls the web site. When the crawling system encounters a reference contained on an accessed page, the crawling system determines whether the reference matches a reference pattern. If the reference matches a reference pattern associated with pages that contain informational content of interest, the crawling system accesses the referenced page. If, however, the reference matches a reference pattern of pages with little informational content, then the crawling system discards that reference without accessing the referenced page.

    Abstract: A vehicle interior classification system and method in accordance with the present invention determines a classification relating to the interior of the vehicle, such as the occupancy status of a vehicle seat or the state of alertness of a vehicle driver, from one or more images of an appropriate portion of the interior of the vehicle acquired with an image capture device. The acquired images are preferably processed to limit the dynamic range of the images to obtain a resultant image which can comprise one or more regions of interest which are less than the total field of view of the image capture device. The resultant images are processed to extract information about features in the image and, in one embodiment, this processing is achieved with a two-dimensional complex discrete wavelet transform which produces a set of coefficients corresponding to the presence and/or location of the features in the resultant image. The set of coefficients produced with such a transform is potentially quite large and can be reduced, through described techniques, to a subset of the total number of coefficients, the members of the subset being selected for their ability to discriminate between the classifications defined for the system. By selecting a subset of the possible coefficients, computational requirements are reduced, as are hardware requirements in the system, such as memory. The selected set of coefficients (whether comprising all of the coefficients or a subset thereof) are provided to a classifier which processes the coefficients with a set of calibration vectors, that were determined when the system was calibrated, to determine the most probable classification for the portion of the vehicle interior.

    Abstract: The present invention provides a photodiode structure with a dark current indication function, including a photosensitive photodiode and a reference photodiode, where a photosensitive surface of the reference photodiode is provided with a light-blocking layer, and there is a fixed multiple relationship between dark currents of the photosensitive photodiode and the reference photodiode. The present invention further provides a photoelectric sensor, including a processing module and the photodiode structure. According to a structural design of the present invention, the photodiode structure may output two paths of current signals, so that an accurate signal photocurrent can be obtained only by subtracting the two paths of current signals in practice work, so as to finally achieve the objectives of eliminating the dark currents and reducing noise; and moreover, in the present invention, the dark currents of photodiodes are eliminated without increasing peripheral devices. Therefore, the present invention has the advantages of being simple in structure and low in cost, and further improving a photoelectric conversion efficiency.
