Project Description:
Our project seeks to detect
images that have been modified to include hidden data. Using LabVIEW, we
examined the 2-dimensional Fast Fourier Transform of altered and unaltered
images. If a discontinuity exists in a frequency band of the image (frequency
domain encoding), then we conclude that the image contains embedded data.
Using this method we were able to successfully detect images that have
been altered to include secret data.
