Otentikasi Image Berbasis Magic Square Orde 𝒏 (Image Authentication Based on Magic Square Order n)
Abstract
Image is a digital media that is easy to change, so it is susceptible to being
used for crime. Image changes may be affected by the unstable internet during
transmission or deliberate manipulation of images for specific purposes. Hence, we
need a tool to determine the authenticity of the image. One strategy that can be used
is to insert code into the entire image, so that any changes to the image information
can be detected. The insertion process performed by dividing the image into several
blocks, where the size of each block is adjusted according to the size of the magic
square order 3. For the authentication process, the image that has been manipulated
will be counted for each pixel. The results show that the manipulated image can be
detected. The parts of the image that have changed can be identified because the
pixel value doesn’t satisfy the magic square rule.
