| 发明名称 | Screen privacy filter using software | ||
| 摘要 | A software-based privacy filter is provided on a computing device. First, a content window is opened and displayed on a display of the computing device. Then a semi-transparent topmost window is created, wherein the semi-transparent topmost window includes a moving privacy pattern designed to obscure first portions of the content window at a first time and obscure second portions of the content window at a second time. The semi-transparent topmost window is then displayed on top of the first content window on the display of the computing device. | ||

| 主权项 | 1. A method for providing a privacy filter on a computing device, the method comprising: opening a first content window; displaying the first content window on a display of the computing device; creating a semi-transparent topmost window, wherein the semi-transparent topmost window includes a moving privacy pattern designed to obscure first portions of the content window at a first time and obscure second portions of the content window at a second time; and displaying the semi-transparent topmost window on top of the first content window on the display of the computing device, wherein said privacy pattern is moving at a rate sufficient to render said moving privacy pattern imperceptible to a user viewing said topmost window at a substantially perpendicular angle to said display. | ||
