image falsification, is simple. An image's authenticity must be confirmed to preserve the image's integrity and prevent misuse. By reducing the image quality and comparing the error level, Error Level Analysis (ELA) can be used to find changes in an image. The most advanced method for resolving classification problems using picture data is the use of deep learning techniques. The goal of this study is to determine the impact of incorporating the ELA extraction procedure into the deep learning approach used to detect image counterfeiting. The picture forgery detection process uses the Convolutional Neural Network (CNN), a deep learning technique. In this study, the effects of applying various ELA compression levels, including 10, 50, and 90%, were also contrasted. The results show that implementing the ELA feature improves test accuracy and boosts validation accuracy by roughly 2.7%. However, the processing time will increase by around 5.6% when ELA is used.

Key Words: CNN, Classification 1. INTRODUCTION Introduction In today's digital environment, image data is incredibly vulnerable to alteration. Today, there is a large variety of image editing software that may be utilized on handheld mobile devices in addition to desktop and laptop computers. In some applications, hyper-realistic faceswapping photos and movies are frequently produced using a deep generative model. The results of this image editing are frequently used for commercial, illegal, and social media objectives. Since picture manipulation can constitute a significant threat to society, the government, and business, it should be a major subject of concern. Therefore, it is necessary to confirm the accuracy of the photographs found online. Therefore, it is essential to safeguard the integrity of digital photos. In this case, the legitimacy of digital photographs can be confirmed using an image forgery detection approach. The field of digital image forensics (DIF) aims to identify the legitimacy of digital photographs by determining the integrity of the image content and the source. There are two main kinds of algorithms—active and passive alteration detection techniques—for detecting image forgeries in DIF. The process of passive forgery detection does not require knowledge of the contents of the image beforehand. The active method, on the other hand, necessitates extracting

The WGAN is trained to differentiate between authentic and manipulated images, achieving promising results in detecting subtle and realistic forgeries in MRIs[3].

The proposed method extracts texture-based features using LBP and feeds them as input to a CNN, enhancing the model's ability to detect texture-based forgeries. The study demonstrates competitive performance on various medical imaging datasets[4]. James Williams, Anna Lee, et al "Forgery Detection in CT Scans using Multi-Modal Fusion and Graph Convolutional
