Abstract

The invention provides a computer implemented method of receiving content at an electronic processing device. The electronic processing device has a data processing application. The method comprises a first step of receiving a message or invitation, said message or invitation not including the content to be received, wherein opening of the message or invitation causes the data processing application to configure a camera of the electronic processing device to capture image data. The data processing application uses image data captured by said camera of said electronic processing device to determine that a user viewing said screen is an authorized or recognized user and, in response to a positive determination, receives said content as encrypted content at said data processing application. In response to a negative determination, the content is not received said content at said data processing application. The data processing application is also configured to not locally store said provided content on said electronic processing device and to disable any screen or video capture functionalities of the electronic processing device.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. Ser. No. 16/800,154 filed Feb. 25, 2020 which is a Continuation-in-Part application claiming priority to U.S. Ser. No. 15/692,019 filed 31 Aug. 2017, each of which is incorporated herein by reference. FIELD OF THE INVENTION The invention relates to a computer implemented method of receiving content at an electronic processing device and, more specifically, to a method of displaying received digital content on a screen of said electronic processing device. BACKGROUND OF THE INVENTION A number of social media applications are available for electronic processing devices such as smart phones, tablet computers and even personal computers (PCs) which seek to display received digital content such as photographs or videos without allowing the user to save the displayed content. One option for preventing displayed content such as a photograph or video being locally saved is to disable any functions on the device such as ‘screenshot’, ‘screensave’ or ‘video capture’ or the like. However, this option does not prevent a user from photographing or videoing the screen by way of indirectly saving the content locally. In another field of endeavor, it is proposed in US2014/0366159 to protect digital content being displayed on a screen of a device by detecting when a number of viewers of the screen increases to more than one. In response to detecting multiple viewers, the display of the digital content is halted. However, the digital content being displayed is stored on the device and is accessible by other means. There is therefore a need for an improved way of displaying digital content such that only an intended user can view it and that unauthorized saving or accessing the digital content locally is prevented. OBJECTS OF THE INVENTION An object of the invention is to mitigate or obviate to some degree one or more problems associated with known methods of displaying received digital content. The above object is met by the combination of features of the main claims; the sub-claims disclose further advantageous embodiments of the invention. Another object of the invention is to provide a system and method for displaying received content on an electronic data processing device to an authorized user but preventing said displayed content being locally saved or accessed on said device. One skilled in the art will derive from the following description other objects of the invention. Therefore, the foregoing statements of object are not exhaustive and serve merely to illustrate some of the many objects of the present invention.
