Fighting crime with digital media Big Data

NetClean can use the Big Data from images to help police investigators.

By James Nunns

NetClean has released its latest version of Analyze Digital Investigator, which includes visual navigation tools that can suggest relationships between millions of data points pertaining to digital media.

The technology is designed to help detect, block and analyse digital media, but with vast amounts of digital media the task of investigating it all can be an impossible task to do manually.

Johann Hofmann, product manager, Analyze, said: "Analyze has always been at the forefront of the digital investigative industry, but we have now made the digital analysis process even more seamless."

"We are excited to introduce Analyze Relations, which gives users the ability to automatically pinpoint and correlate information of interest in what can seem like a needle in a haystack. Ultimately, investigators are able to produce better results and maximise their limited resources."

"For example, in a child sexual abuse case, an innocent photo (with EXIF data intact) and an abuse image (where it has been removed) could have been taken on the same camera, Analyze actively suggests and visualises that connection for the investigator, and puts it in the context of hundreds more connections that it may have been able to find."

This solution aims to actively connect the dots between images and can build a visual map to help further investigators ability to gain actionable intelligence from visual big data.

This works by comparing multiple types of data collected from digital media, such as what camera was used, when and where the image was taken and particular attributes in the image.
