  • Publication number: 20170034020
    Abstract: In one embodiment, one or more BitTorrent management pages, such as an index site or a Rich Site Summary (RSS) feed, may be scanned for indicia of a torrent file that is associated with one or more search terms. After the torrent file is located, information associated with the torrent file may be utilized to initiate the downloading of one or more portions of the content indicated by the torrent file over a network from swarm computers utilizing a BitTorrent Protocol. As the content is being downloaded from the swarm computers, identification information associated with each swarm computer may be obtained. Data associated with the torrent file and the identification information may be stored at a database. Thereafter, a client may search the database to locate one or more swarm computers that may be sharing, for example, unauthorized or illegal information.

  • Patent number: 9260672
    Abstract: The present invention provides a process for deep desulphurization of cracked gasoline with minimum octane loss of about 1-2 units. In this process full range cracked gasoline from FCC, Coker, Visbreaker etc is sent to Diolefin Saturation Reactor for selective saturation of diolefins. After saturation of diolefins, the stream is sent to Splitter for splitting into three cuts i.e Light Cut (IBP-70° C.), Intermediate Cut (70-90° C.) and Heavy Cut (90-210° C.). The Light Cut which contains majority of the high octane olefins and mercaptan sulfur is desulfurized with caustic treatment using Continuous Film Contactor (CFC). The sulfur in the Intermediate Cut is also predominantly mercaptans and the cut can be desulfurized by caustic treatment using CFC along with Light cut or separately desulfurized before being sent for isomerization. The Heavy Cut containing mainly thiophinic sulfur compounds is treated either by using conventional HDS process or reactive adsorption process.

  • Patent number: 9135306
    Abstract: A “data breach” or loss of sensitive data can cause an organization to lose revenues or suffer other damages. Analyzing data to locate a breach and to identify its source, however, is difficult because the data can come from many sources in an unstructured format and, typically, there is a large amount of data to analyze. A forensic analysis system, according to one embodiment, collects unstructured data from disparate sources, like the Internet, and peer-to-per filesharing and social media networks, and generates structured representations of the data, called virtual profiles. The system forms relationships among the virtual profiles. The system uses the virtual profiles and relationships to reduce the amount of information to be analyzed while including additional information that is related for analysis. By analyzing a smaller amount of related information, a cyber forensic analyst is better able to identify a data breach or other suspicious or illegal activity.
