Information Hiding Using Temporally Brightness Modulated Pattern

Abstract

A new display system technology that may hide secret data behind a displayed image, whereas at the same time satisfying each high physical property and readability needs. The hidden data may be a reasonably binary image as well as characters, and varied varieties of patterns, i.e., Quadratic Residue (QR) codes. This system uses a temporally bright modulated invisible pattern in an exceedingly moving image, or video. Frame pictures over some period’s area unit summed up once scan out, enhancing the distinction of the invisible pattern to create it visible. We have a tendency to conjointly propose a replacement technique to unravel a problem that happens thanks to asynchronous operations of the show and video camera that may be a technique that was achieved by mistreatment time shift sampling. The hidden binary image scans out per experiments that we conducted to substantiate the results. Moreover, the patterns employed in this system were in spades invisible once arranged behind the most pictures, that steered the planned technology was extremely possible in sensible applications per this confirmation. At the decoder facet, a robust two-class SVM classifier is meant to tell apart encrypted and unencrypted image patches, permitting North American country to put together rewrite the embedded message and therefore the original image signal. Compared with the progressive ways, the planned approach provides higher embedding capability and is ready to dead reconstruct the first image likewise because the embedded message.
