    摘要: A document accessible over a network can be registered. A registered document, and the content contained therein, cannot be transmitted undetected over and off of the network. In one embodiment, the invention includes maintaining a plurality of stored signatures in a signature database, each signature being associated with one of a plurality of registered documents. In one embodiment, the invention further includes maintaining the signature database by de-registering documents by removing the signatures associated with de-registered documents. In one embodiment, the invention further includes maintaining the database by removing redundant and high detection rate signatures. In one embodiment, the invention also includes maintaining the signature database by removing signatures based on the source text used to generate the signature.

    摘要: Objects captured over a network by a capture system can be indexed to provide enhanced search and content analysis capabilities. In one embodiment the objects can be indexed using a data structure having a source address field to indicate an origination address of the object, a destination address field to indicate a destination address of the object, a source port field to indicate an origination port of the object, a destination port field to indicate a destination port of the object, a content field to indicate a content type from a plurality of content types identifying a type of content contained in the object, and a time field to indicate when the object was captured. The data structure may also store a cryptographic signature of the object to ensure the object is not altered after capture.

    摘要: Packets can be read from a network interface into an application using a single kernel copy. In one embodiment, the invention includes a receiver packet memory to store captured packets, and a network interface driver operating in a kernel of a device to read packets captured by network interface hardware into the kernel by storing captured packets in the receiver packet memory. Then, an application interface can expose the receiver packet memory to an application executing on the device by representing the receiver packet memory as a virtual file.

    摘要: Visual objects can be classified according to image type. In one embodiment, the present invention includes capturing a visual object, and decompressing the visual object to a colorspace representation exposing each pixel. The contribution of each pixel to a plurality of image types can then be determined. Then, the contributions can be combined, and the image type of the visual object can be determined based on the contributions.

    摘要: In one embodiment of the present invention, a rule compiler can compress a plurality of rules to be parsed over a block of data into one state table tree structure. In one embodiment of the present invention, rue parsing over the block of data includes selecting a unit of the block of data, indexing into a state table of the state table tree using the selected unit. The state table indexed into can be used for determining whether a decision regarding the block of data can be reached based on the indexed entry, and for selecting a next state table indicated by the indexed entry if the decision regarding the block of data cannot be reached.
