Analog Video and its "Pornographic Years"

Managing Analog and Digital Video Clips

The V3 Video Server is a demonstration showing a multimedia application developed on top of the VODAK database management system. VODAK is a prototype of an object-oriented and distributed database management system (DBMS) developed at GMDIPSI. The V3 Video Server allows a user to interactively store, retrieve, manipulate, and present analog and short digital video clips. A video clip consists ...

Watermarking of Analog and Compressed Video

Watermarking techniques allow the embedding of additional information directly into digital media as audio and video. Small variations of the digital representation of those data are used to imperceptibly combine the watermark content with the media. Ideally, no subsequent modification will destroy the watermark. However, in practice, the robustness depends on the watermark energy used, which i...

User-generated Pornographic Video Detection Using Shot-based Sensor Pattern Noise

Illegal distribution of user-generated pornography (UGP) videos raises lots of negative aspects associated with the digital contents. This paper proposes a first forensic technique to detect UGP video. To discriminate UGP videos, we exploit shot based sensor pattern noise (SPN) from an image under investigation. By thresholding average peakto-correlation (PCE) values from the shot based SPNs, t...

Non-retrieval: Blocking Pornographic Images

We extend earlier work on detecting pornographic images. Our focus is on the classification stage and we give new results for a variety of classical and modern classifiers. We find the artificial neural network offers a statistically significant improvement. In all cases the error rate is too high unless deployed sensitively so we show how such a system may be built into a commercial environment.
