fake image detection 2021




Due to the significant advancements in image processing and machine learning algorithms, it is much easier to create, edit, and produce high quality images. However, attackers can maliciously use these tools to create legitimate looking but fake images to harm others, bypass image detection algorithms, or fool image recognition classifiers. In this work, we propose neural network based classifiers to detect fake human faces created by both 1) machines and 2) humans. We use ensemble methods to detect GANs-created fake images and employ pre-processing techniques to improve fake face image detection created by humans. Our approaches focus on image contents for classification and do not use meta-data of images. Our preliminary results show that we can effectively detect both GANs-created images, and human-created fake images

Many fake images are spreading through digitalmedia nowadays. Detection of such fake images is inevitable forthe unveiling of the image based cybercrimes. Forging imagesand identifying such images are promising research areas in thisdigital era. The tampered images are a detected using neuralnetwork which also recognizes the regions of the image that havebeen manipulated and reveals the segments of the original image.It can be implemented on Android platform and hence madeavailable to common users. The compression ratio of the foreigncontent in a fake image is different from that of the originalimage and is detected using Error Level Analysis. Anotherfeature used along with compression ratio is image metadata.Although it is possible to alter metadata content making itunreliable on its own, here it is used as a supporting parameterfor error level analysis decision
