Abstract:
This study proposes inattentive image
watermarking scheme for tamper detection. By comparing
pixel channel values of the image, the scheme endows to
distinguish tamper attacks such as blurring, replacing, adding
features from non - tamper regions out coming from general
image processing operations. This technique can be
implemented with small memory and computational
requirements, which makes it potentially useful for hardware
implementation in digital cameras. The scheme works by
increasing the pixel value of odd number of an each pixel
channel by one and embedding the hidden data value into the
base image, robust watermark that sensitively depends on a
secret key. The technique of watermarking method is designed
based on Least Significant Bit algorithm. To achieve of finding
the tamper region on the tampered image, this study proposed
the inverse extraction procedure that extracts the watermark
region and tampered region on the testing image.
