  • Patent number: 8176173
    Abstract: Embodiments locate a botmaster on a network. A honeynet host is configured to join a botnet and generate a watermarked packet flow by applying a watermark to an outgoing packet flow in response to commands from the botmaster. The watermark is applied to the outgoing packet flow by: choosing distinct packets from the outgoing packet flow; forming packet pair(s) from the distinct packets, that include a reference packet and an encoding packet; and encoding bits in the watermark to the packet pair(s) by increasing the length of the encoding packet when watermark bits have a predetermined value. The cooperating node(s) are configured to: inspect passing packet flows for the watermarked packet flow and generate tracking information related to detection of the watermarked packet flow. The path determination processor is configured to analyze the tracking information to locate a path taken by the watermarked packet flow.

  • Patent number: 8145583
    Abstract: Disclosed is a medical outcome prediction tool that predicts an individual patient's medical outcomes by identifying patients having a same disease; selecting a set of characteristics unique to an individual; determining the similarities between the individual and other cases; and calculating the expected outcome for the individual that is proportional to a weighted sum of outcomes of similar cases. The similarities can be determined by calculating the number of matches between the individual and cases over the set of characteristics, and using that result to determine a similarity score.

  • Patent number: 8131998
    Abstract: A system, apparatus and method for transparently authenticating continuous data streams. A continuous data stream is divided into data blocks. Block authentication code(s) are determined using the data in the data blocks, a hash function and a key. The block authentication code(s) are embedded into the data block(s) by adjusting the timing between the packets in the data block(s). Timing delays may be used to separate the blocks. The continuous data stream may be received and authenticated by comparing an extracted block authentication code with a new calculated content-based block authentication code.

  • Patent number: 8019127
    Abstract: A system and method for determining if a computer user is a human or a computer program. A computer user is presented with a series of images, the series of images including: at least two related images of an object, at least one of the at least two related images independently processed using an image modifying algorithm; and at least one unrelated image. The computer user is then requested to identify the related images from the series of images. These image identifications are received from the computer user. A determination is made that the computer user is: a human if the image identifications only identify the related images from the series of images; and a non-human if the image identifications do not only identify the related images from the series of images.
