AI总结:

针对数字视频源摄像机识别问题,提出基于特征提取、特征选择与分类的盲取证技术,利用机器学习确定视频声称的源是否为原始源,实验证明其优于传统指纹方法。

摘要:

数字视频的源摄像机识别是指在可能的设备闭集中,将未知数字视频与其源设备相关联的问题。现有数字视频源检测技术试图以PRNU(Photo Response Non-Uniformity,光响应非均匀性)的形式在视频中寻找实际源的指纹,并将其与每个可能设备的SPN(Sensor Pattern Noise,传感器模式噪声)进行匹配。最高相关性指示正确的源。我们研究了通过基于特征的机器学习方法来识别视频源的问题。本文提出了一种视频源认证与识别的盲取证技术,基于特征提取、特征选择及随后的源分类。主要目标是确定视频所声称的源是否为其真正的原始源。若否,我们识别其原始源。实验结果证明了所提方法相较于传统基于指纹技术的有效性。

英文摘要:

Source camera identification in digital videos is the problem of associating an unknown digital video with its source device, within a closed set of possible devices. The existing techniques in source detection of digital videos try to find a fingerprint of the actual source in the video in form of PRNU (Photo Response Non--Uniformity), and match it against the SPN (Sensor Pattern Noise) of each possible device. The highest correlation indicates the correct source. We investigate the problem of identifying a video source through a feature based approach using machine learning. In this paper, we present a blind forensic technique of video source authentication and identification, based on feature extraction, feature selection and subsequent source classification. The main aim is to determine whether a claimed source for a video is actually its original source. If not, we identify its original source. Our experimental results prove the efficiency of the proposed method compared to traditional fingerprint based technique.
