In present days, individuals in the society are becoming increasingly relying on multimedia content, especially digital images and videos, to provide a reliable proof of the occurrence of events. However, the availability of powerful and user-friendly video editing tools makes it easy even for a novice to manipulate the content of a digital video which may be used as evidence during digital investigation. This has led to great concern regarding the trustworthiness of digital videos. A number of techniques have proposed in the literature for different types of digital video forgery detections. In this work, a hybrid technique for detecting and localizing splicing video forgery using convolutional auto-encoder and GOTURN (Generic Object Tracking Using Regression Network) is proposed. The parameters of the auto-encoder are learned during the training phase on original video frames. During the testing phase, the auto-encoder reconstructs the original frames with small reconstruction error and the forged frame with large reconstruction error. The forged material is then tracked in subsequent frames using GOTURN algorithm. The result of the experiments demonstrates that the proposed detection technique can adequately detect video splicing with an AUROC ( Area Under the Receiver Operating Characteristics ) value of 0.9307.
