| 20090232391 | Identifying Image Type in a Capture System - 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. | 09-17-2009 |
| 20100121853 | QUERY GENERATION FOR A CAPTURE SYSTEM - A document accessible over a network can be registered. A registered document, and the content contained therein, is not transmitted undetected over and off of the network. In one embodiment, the invention includes a manager agent to maintain signatures of registered documents and a match agent to detect the unauthorized transmission of the content of registered documents. | 05-13-2010 |
| 20100185622 | Attributes of Captured Objects in a Capture System - Regular expressions used for searching for patterns in captured objects can be grouped into attributes. Such attributes can be associated with captured objects using tags stored in a database. In one embodiment, the present invention includes capturing an object being transmitted over a network, and determining that a regular expression appears in the object, the regular expression belonging to a group of one or more regular expressions associated with an attribute. If a regular expression associated with the attribute is found in the object, then an attribute field of a tag containing metadata related to the captured object is set to indicate the presence of the attribute in the captured object. The presence of the attribute in the captured object can now be determined from the tag, which can be stored in a database. | 07-22-2010 |
| 20100268959 | Verifying Captured Objects Before Presentation - Objects can be extracted from data flows captured by a capture device. Each captured object can then be classified according to content. Meta-data about captured objects can be stored in a tag. In one embodiment, the present invention includes receiving a request to present a previously captured object to a user, accessing a tag associated with the requested object, the tag containing metadata related to the object, the metadata including an object signature, and verifying that the object has not been altered since capture using the object signature before presenting the object to the user. | 10-21-2010 |
| 20110004599 | A SYSTEM AND METHOD FOR WORD INDEXING IN A CAPTURE SYSTEM AND QUERYING THEREOF - Searching of objects captured by a capture system can be improved by eliminating irrelevant objects from a query. In one embodiment, the present invention includes receiving such a query for objects captured by a capture system, the query including at least one search term. This search term is then hashed to a term bit position using a hash function. Then objects can be eliminated if, in a word index associated with the object, the term bit position is not set. | 01-06-2011 |
| 20110149959 | HIGH SPEED PACKET CAPTURE - 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. | 06-23-2011 |
| 20110167265 | CRYPTOGRAPHIC POLICY ENFORCEMENT - Objects can be extracted from data flows captured by a capture device. In one embodiment, the invention includes assigning to each captured object a cryptographic status based on whether the captured object is encrypted. In one embodiment, the invention further includes determining whether the object violated a cryptographic policy using the assigned cryptographic status of the object. | 07-07-2011 |
| 20110196911 | TAG DATA STRUCTURE FOR MAINTAINING RELATIONAL DATA OVER CAPTURED OBJECTS - 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. | 08-11-2011 |
| 20110197284 | ATTRIBUTES OF CAPTURED OBJECTS IN A CAPTURE SYSTEM - A system and method for capturing objects and balancing systems resources in a capture system are described. An object is captured, metadata associated with the objected generated, and the object and metadata stored. | 08-11-2011 |
