Title: Graphics processing systems
Inventor: DAREN CROXFORD
IPC: H04N5/232
Filed: 2017-10-06
Abstract: The invention discloses a method of operating a graphics processing system. A sequence of source frames 40 depicting one or more objects is generated. The source frames are rendered based on a first viewpoint, and the position of an item 42 with respect to the line-of-sight (LOS) is determined. These source images are then transformed into further different versions 41A-41D, according to received user head orientation data and the variation of the relative locations of viewpoints and the one or more objects, or their motion (Fig. 19). The selection of the one or more additional rotated viewpoints may depend on properties of the object itself or the processing capability of the graphics processing system. Furthermore, the method may account for features which are partially occluded in some pictures, but visible in others (Fig. 10).

IPC: G06F21/55
Filed: 2019-02-25
Abstract: A system, method, apparatus, and computer program product to detect page impersonation in phishing attacks. The system detects phishing attempts by extracting an embedded URL from an e-mail message and captures a screenshot image of the referenced site. The captured screenshot is analyzed with an image recognition module that compares the captured screenshot with a record screenshot of one or more trusted sites. If the comparison indicates that the screenshots differ, the embedded URL is marked as safe. If the comparison indicates that the screenshots are the same, the domain of the embedded URL is compared with the domain for the trusted site. When the domains differ, the e-mail is marked as a page impersonation attempt. When the domains correspond, the e-mail is marked as safe. The system includes a page impersonation database of trusted site URLs, domains, and record screenshots.
