Abstract: Systems and Methods are utilized for determining a software signature. A software program in a form of a sequence of instructions of the software program is obained. The software program is clustered into a software family. A signature for each software family is generated.

Abstract: A system and a method for determining at least one software signature, comprising: performing process associated with obtaining a software program in a form of a sequence of instructions (SOI) of the software program; and performing processing associated with generating a signature for the software program where the signature comprises a ratio of a set of SOI counts over total SOI counts of the software program.

Abstract: Using stochastic directed graphs, a social network stochastic directed graph model allows for policy analysis and action. An activity generator may be used for creating agents that represent a population stratum. Agents may be proportionally selected to the size of the population stratum and representative activities that are associated with said population stratum. Agents have one or more conditional probabilities attached to the activities, which indicate the likelihood of interaction between agents and one or more agents or actors. Outcomes for the interactions may be accumulated. Based on these outcomes, which include benign and acute, a multinomial probability distribution may be estimated.

Abstract: A tangible computer readable medium encoded with instructions for automatically generating metadata, wherein said execution of said instructions by one or more processors causes said “one or more processors” to perform the steps comprising: a. creating at least one feature vector for each document in a dataset; b. extracting said one feature vector; c. recording said feature vector as a digital object; and d. augmenting metadata using said digital object to reduce the volume of said dataset, said augmenting capable of allowing a user to perform a search on said dataset.

Abstract: The present invention relates to systems and methods for generating and displaying an immersive three-dimensional visual environments. In preferred aspects of the invention, the system uses a central processing unit which contains a low-cost commodity chip. The immersive system can further comprise a voice recognition component which is utilized to manipulate the visual environment.
