Claim 17:
18. A method for screen capture disablement, comprising:
in a screen capture disablement (SCD) module of a digital rights management (DRM) Mobile Messaging application (App),
receiving, at a DRM Cloud Server, a DRM-restricted photo, from a sender mobile device having the DRM Mobile Messaging App installed thereon, wherein a DRM restriction is screen capture disablement;
splitting, at the DRM Cloud Server, the DRM-restricted photo into two or more subframes by identifying pixels that make up the DRM-restricted photo, and then dividing the pixels into two or more subframes, wherein the DRM restriction includes a command to alternate display of the two or more subframes at 30 Hz, permitting a human eye to construct a complete image and causing a screen capture function to capture a blurry image;
wherein dividing comprises a step selected from the group consisting of:
removing a portion of horizontal pixel lines from a first subframe and removing a portion of vertical pixel lines from a second subframe;
dynamically presenting a sequence of incomplete subframes;
splitting the DRM-restricted photo into multiple subframes, each subframe having pixels only in a subsection at a specific geographic grid address and redacting all other pixels, wherein any specific subframe will have entire subsections redacted and having zero pixels and at higher frame rates of 120-1000 Hz, a screen capture function will only capture a highly pixelated subframe;
splitting the DRM-restricted photo into a first sampling subframe and one or more in-fill subframes of unequal sizes, in terms of number of pixels, wherein a sampling subframe uses a sampling setting to ensure that the screen capture function of recipient mobile device captures a blurry image while maintaining sufficient image quality to enable the human eye to process a clear image, wherein a range from 30-1000 frames per second (fps)(Hz), is used for sequencing of the subframes to construct a composite image; and
transmitting the subframes of the split DRM-restricted photo to a recipient mobile device having the DRM Mobile Messaging App thereon, wherein the DRM restriction command instructs the recipient mobile device to alternate display of the subframes at a rate permitting a human eye to construct a complete image and causing a screen capture device to capture a blurry image.
