The popularity of Digital Image has widely increased in society. Nowadays, by the easy availability of image editing software people can manipulate the image for malicious intent. Our proposed method is to detect inconsistency in the exact area of an image. The paper involves different steps, i.e., preprocessing, feature extraction, and matching processes. In feature extraction, we apply Discrete Cosine Transform (DCT). Evaluate our system by calculating True Positive Rate (TPR), False Positive Rate (FPR), and Area Under the Curve (AUC) of 0.3372, 0.5278, and 0.949, respectively. The results show more efficiency.
