Abstract: Implementations provide visual cryptographic techniques that obscure text using pixel manipulation and multiple visual layers. The visual cryptography techniques implemented in embodiments manipulate the pixel values of an image that define target text and generate multiple layers using the manipulated pixel values. The generated layers are configured such that successive and rapid display of the layers generates an obscured version of the image and a legible version of the target text when viewed by a person. However, implementations generate and/or display the layers such that the target text is illegible in captured image(s) or video of the obscured version of the image. Thus, embodiments provide an obscured version of an image with legible target text when viewed by a person, but the target text is illegible in captured image(s) or video of the obscured version of the image due to insufficient information capture.
