2 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico I-DASH goals To develop a collection of integrated tools capable of handling thousands of hours of videos potentially containing child pornography. The tools will focus on filtering out irrelevant material, recognition of known child pornography, interactive search in the material and establishing links between different videos. To establish a standard to exchange video fingerprints and corresponding data to facilitate international collaboration and development of new kinds of technology. To establish a European database with video fingerprints of known child pornography, allowing for efficient filtering of data and facilitating collaboration between national police forces.

7 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico Classify large amount of video and images Exact copy detection (MD5, SHA1) IMAGEfingerprinting Or near copy detection or Near hashing on images VIDEOfingerprinting Nearcopy detection on video Video linking Location matching Object matching Interactive search Genre classification Concept searches Off-the-shelf productsHigh science VizXview (video) VizXimage (picture) I-DASH first prototype I-DASH project

8 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico Overview Baseline: VizXview and VizXimage VIDEOfingerprinting Interactive search

9 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico Baseline Video: 1 hour in 1 minute Images: on a single machine Nudity detection MD5/SHA1 Hashing IMAGEfingerprinting (other names for this techniques are nearhashing or nearcopy detection) Huge codecset for both video and images More then hours of video classified so far More then images classified so far

10 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico Videofingerprinting Aim –Identify video material which has already been classified in earlier cases as being child pornography

11 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico For video youll often find … Resolution change Color change noise transcoding

12 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico MD5 hashes work for exact copies only: 32 characters, hexadecimal A0D5DA345 original modified F color noise size crop transcoding EDF12645A Videofingerprinting will yield a signature of each video which is robust against the various types of transformations

13 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico Global workings of VIDEOfingerprinting Video database Fingerprint Repository Videofile Fingerprinting Annotation Key Adding a videofile to the repository

14 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico Video database Fingerprint Repository Videofile Fingerprinting Searching Annotation Key Searching/matching for a videofile in the repository

15 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico Interactive search Both from a technological viewpoint and from a business perspective there are three approaches Genre classification to support the classification process. Filter out harmless material like normal home video, Hollywood movies, sport videos, normal porn, … Concept search to support the classification process. To find videos with screaming children, children expressing fear, interviews, faces, porn, nudity, bed or … Location and object matching to support crosslinking and tactical investigation

16 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico Genre Classification Potentially relevant data Captured video collection Clearly Harmless Data Genre Classification

17 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico Automatically detect TV-recordings, Hollywood movies, sports, harmless home videos or normal porn Based on for example average shot length number of different camera positions movement image quality Remarks: Technology is based on statistics. The longer the video the better the prediction. Do we trigger on a hidden child porn scene of 1 minute in a sportsvideo of one hour? Genre classification

18 University of Surrey, ZiuZ, University of Amsterdam, TNO, Instituto Superior Technico Semantic search engine New material Ranking of the data based on relevance to the query Audio Indexing: screaming, children, pool Visual Indexing: indoor, person, pool, beach Concept based search
