Visual incongruity in search result sets may be reduced at least in part by searching an optimized visually significant subset of a category tree that categorizes a collection of content. The category tree may be optimized at build time at least in part by pruning with respect to visual coherence and by the size of the content collection subset referenced by particular categories. Content collection subset sizes both too large and too small can detract from the visual significance of a particular category. The visually significant subset of the category tree may be further optimized at query time by intersecting the visually significant subset with the query-associated sub-tree(s) and further pruning categories in the visually significant subset that have child categories in the visually significant subset. Searching with respect to the optimized visually significant subset can also improve search efficiency.

Refinement shape content search

Present invention relates to a method and system for automatic searching for information on a network in response to an image query sent by a user. The image query includes an image that is captured by using a mobile communications device with a camera. The image is processed to detect the text present in it. The detected text is then recognized using an OCR. Subsequently, the text is searched for matches in the corresponding domain database, selected from the various domain databases present in the network. Thereafter, selected matches and additional related information is sent to the user.

Content search with category-aware visual similarity

The present invention relates to a method, system, and a computer program product for delivering content to a communication device, in response to an image sent by the communication device. The received image is matched with a plurality of images, and, when a match is found for the received image, content corresponding to the image is delivered to the communication device. The plurality of images is stored in an image database, and the corresponding content is stored in a content repository. The present invention enables a content provider to automatically update the image database and the content repository without any human intervention.

Systems and methods are discussed for providing multiple network interfaces to devices to communicate with each other using various policies, for using a proxy to maintain a connection with a legacy system such that a data connection to the legacy system may be continued when an end device connects with the proxy, and for maintaining application states when devices become disconnected such that their activities may be resumed when reconnected. Multiple wireless networks allow communication sessions to transfer across each of the multiple wireless networks in a seamless fashion. One wireless network may control the handoff to another wireless network or a mobile device with an OCMP may control the handoff.

Wireless network augmentation using other wireless networks

A system and a method for identifying significant behaviors from network traffic. A probability value is assigned to each cluster in a set of clusters. An uncertainty value is computed indicating a level of variability among the probability values. One or more clusters are removed from the set of clusters until the uncertainty value exceeds a desired uncertainty threshold, and each of the removed clusters is identified as a significant cluster.

Identifying significant behaviors within network traffic

The invention relates to a system and method for generating realistic network traffic by replaying captured network traffic using parallelized streams of subtraces. In accordance with one method of the invention, a captured trace of network traffic from a network link is provided. The captured trace is split into a number of subtraces. The subtraces are replayed and then recombined into a recombined trace, wherein the timing of packets in the recombined trace approximates the timing of packets in the captured trace.

System and method for trace replay using parallelized streams

The present invention relates to a method, system, and a computer-readable storage medium containing executable instructions for delivering content to a communication device, in response to an image sent by the communication device. The received image is matched with a plurality of images, and, when a match is found for the received image, content corresponding to the matching image is delivered to the communication device. The plurality of images is stored in an image database, and the corresponding content is stored in a content repository. The present invention enables a content provider to automatically update the image database and the content repository without any human intervention.

Systems and methods are discussed for providing a continuous monitoring system for high-speed links. Data packets are passively read in a high-speed environment. Concurrent streams are created to handle the high-speed data packets and to manipulate subsets of data packets in modules for output to various applications or destinations. The modules can include algorithms or filters created for various tasks.

CMON: an 'always-on' monitoring platform for high-speed links

A system and a method for profiling traffic on a computer network. Flows are observed traversing a communication link. Relative uncertainty values are computed for the dimensions of these flows. These relative uncertainty values are used to identify dominant feature values in the various flow dimensions. Flows having these dominant feature values are filtered.

Profile-aware filtering of network traffic

Image-based searching for information on a network is provided in response to an image query sent by a user. The image query includes an image captured using a mobile communications device with a camera. The image is processed to detect any text present in the image, and any detected text can be analyzed using a process such as optical character recognition (OCR). The analyzed text is used to search for matches in at least one corresponding domain database, selected from various domain databases present in the network. Thereafter, one or more selected matches and any additional related information can be sent to the user as one or more results for the submitted image query.

A system and a method for detecting port scanning activities on a computer network. A probability variable is assigned to a device on a computer network. The probability variable indicates the probability that the device is conducting port-scanning activities. Data describing transmissions by the device during multiple intervals of time is accessed, and, for each of the time intervals, a determination is made concerning whether or not the device conducted port-scanning activities. Based on these determinations, the probability variable is updated for each of the time intervals.
