Patent number: 9584539Abstract: A method scans a second web page linked to a first web page being displayed by a browser. The method identifies a target link to the second web page. Prior to receiving a user selection of the target link, the method prefetches content from the second web page and loads it into a safe cache before receiving the user selection of the target link. The method scans the prefetched content for a security threat, within the safe cache, which is configured to prevent the prefetched content from altering a memory or storage location external to the safe cache. The method detects user placement of a cursor proximate to the target link and, in response to identifying a security threat, presents a warning to the user, or in response to identifying no threat or the user opting to ignore the warning, causing display of a second window comprising the prefetched content.Type: GrantFiled: February 19, 2016Date of Patent: February 28, 2017Assignee: Cufer Asset Ltd. L.L.C.Inventors: Scott Milener, Wendell Brown, James Kelly

Patent number: 9299088Abstract: A multi-dimensional information repository storing data structures and tags associated with individual ones of the data structures. The data structures are tagged according to locations and defined regions relative to the surface of the Earth, and a data retrieval system retrieves information from the data structures according to location data accompanying requests for data. Data structures can also be tagged relative to time in addition to location and defined regions, and both tags can be used in retrieving data structures. A subscription server using the data repository can have a communication module for receiving data requests accompanied by location data and a code set for managing retrieval of information from the data repository. The subscription server can use the accompanying location data to determine a location in pre-defined regions, and use the pre-defined region information to retrieve information related to the pre-defined regions in response to the data requests.Type: GrantFiled: April 24, 2015Date of Patent: March 29, 2016Assignee: Cufer Asset Ltd.

Patent number: 9270699Abstract: A method scans a second web page linked to a first web page being displayed by a browser in a browser window. The method identifies, in the first web page, a target link to the second web page. Prior to receiving a user selection of the target link, the method prefetches content from the second web page and loads it into a safe cache before receiving the user selection of the target link and before the content of the second web page is opened by an application configured to provide access to the content of the second web page. The method scans the prefetched content from the second web page for a security threat, within the safe cache, which is configured to prevent the prefetched content from altering a memory location or storage location external to the safe cache.Type: GrantFiled: July 11, 2014Date of Patent: February 23, 2016Assignee: Cufer Asset Ltd.
