Method and Apparatus for Deep Packet Inspection for Network Intrusion Detection

In a method of determining whether a data stream includes unauthorized data, the data stream is analyzed using a hardware filter to detect a presence of one or more of a first set of patterns in the data stream. It is determined whether a packet in the data stream belongs to one of a plurality of data flows to be further inspected based on the analysis of the data stream by the hardware filter. A set of rules is applied to the packet to produce rule match status data if it is determined that the packet belongs to one of the plurality of data flows to be further inspected. The packet is analyzed to determine if the packet includes unauthorized data using software stored on a computer-readable medium and implemented on a processor if the rule match status data indicates that the packet potentially includes unauthorized data.

Perception-based image retrieval

A content-based image retrieval (CBIR) system has a front-end that includes a pipeline of one or more dynamically-constructed filters for measuring perceptual similarities between a query image and one or more candidate images retrieved from a back-end comprised of a knowledge base accessed by an inference engine. The images include at least one color set having a set of properties including a number of pixels each having at least one color, a culture color associated with the color set, a mean and variance of the color set, a moment invariant, and a centroid. The filters analyze and compare the set of properties of the query image to the set of properties of the candidate images. Various filters are used, including: a Color Mask filter that identifies identical culture colors in the images, a Color Histogram filter that identifies a distribution of colors in the images, a Color Average filter that performs a similarity comparison on the average of the color sets of the images, a Color Variance filter that performs a similarity comparison on the variances of the color sets of the images, a Spread filter that identifies a spatial concentration of a color in the images, an Elongation filter that identifies a shape of a color in the images, and a Spatial Relationship filter that identifies a spatial relationship between the color sets in the images.
