Microsoft's new technology - PhotoDNA

STATE and federal police will begin using sophisticated image-matching software to tag and track child pornographic images in an attempt to reduce their sharing across the internet.

The technology, developed by computer giant Microsoft's research group along with scientists from Dartmouth College, creates a unique signature on a digital image that could be compared with the signature of other images to determine if they were copies.

The manager of cyber crime operations at the Australian Federal Police, Glen McEwen, said when police came across child abuse material their first priority was to establish whether the images were new, and the child was still at risk, or whether they were versions of known images.
That process was currently carried out manually by police officers, he said.

Commander McEwen said,”access to the new technology, called PhotoDNA, will mean police could identify victims and apprehend abusers faster, and make it easier for enforcement agencies to share information”.

The technology would also limit officer’s exposure to disturbing material, he said.
