Abstract

Digital forgery detection implies the identification of any modifications or manipulation of the digital content, typically image, video, or document, to confirm their authenticity. Consequently, this contribution seeks to address the challenges experienced by existing techniques by introducing the Modified DepthResNet descriptor and Layer Optimized Dunnock Deep model (MDR-LOD2) model. MDR descriptor is proficient at generating features in ResNet architecture and hence it helps in the fusion of a DepthNet to detect depth-related cues which plays a crucial role in spotting forgery. More specifically, the MDR descriptor captures the subtle details via the spatial connections and depth perception, resulting in boosting the detection performance. The hybrid optimizer strategy combines meticulous exploration and dynamic adaptation together increasing the model's ability to detect splicing forgery. The proposed approach exploits the LOD2 architecture well suited for capturing the temporal aspects and effectively analyzes the intricate patterns of video data. Additionally, the LOD2 model is enabled with the Dunnock Hunt Optimization (DHO) algorithm for layer optimization facilitating optimal performance of every layer in LSTM. Moreover, the integration of LOD2 and MDR descriptor in conjunction with the DHO algorithm in the proposed approach assist in identifying the forged regions in the video frames. The experimental results demonstrate that the proposed approach attains an accuracy of 98.54 %, sensitivity of 98.54 %, specificity of 98.53 %, and F1-score of 98.54 % for DSO-1. For DSI-1 DTS, the proposed approach achieves remarkable results with high accuracy of 98.47 %, sensitivity of 98.41 %, specificity of 98.52 %, and F1-score of 98.47 %. Finally, the proposed model obtained the remarkable results for the Face Forensics database achieving high accuracy of 97.83 %, sensitivity of 97.76 %, specificity of 97.89 %, and F1-score of 97.83 % outperforming other existing techniques.
MDR-LOD2模型:基于改进深度ResNet特征和图层优化Dunnock深度模型的视频伪造检测
数字伪造检测意味着对数字内容(通常是图像、视频或文档)的任何修改或操作进行识别,以确认其真实性。因此,本文旨在通过引入Modified DepthResNet描述符和Layer Optimized Dunnock Deep model (MDR-LOD2)模型来解决现有技术所面临的挑战。MDR描述符精通于在ResNet架构中生成特征,因此它有助于融合深度网络来检测深度相关的线索,这在发现伪造中起着至关重要的作用。更具体地说,MDR描述符通过空间连接和深度感知捕捉细微细节,从而提高检测性能。混合优化策略将精细探索和动态适应相结合,提高了模型检测拼接伪造的能力。所提出的方法利用LOD2架构,非常适合于捕获时间方面,并有效地分析视频数据的复杂模式。此外,LOD2模型还启用了Dunnock Hunt Optimization (DHO)算法进行层优化,从而使LSTM中的每一层都具有最佳性能。此外,该方法将LOD2和MDR描述符与DHO算法相结合,有助于识别视频帧中的伪造区域。实验结果表明,该方法对DSO-1的检测准确率为98.54%,灵敏度为98.54%,特异性为98.53%,f1评分为98.54%。对于DSI-1 DTS,该方法准确率为98.47%,灵敏度为98.41%,特异性为98.52%,f1评分为98.47%,效果显著。最后,该模型在人脸取证数据库中取得了显著的效果,准确率为97.83%,灵敏度为97.76%,特异性为97.89%,f1评分为97.83%,优于现有的其他技术。
