Microsoft delivers PhotoDNA to protect community from cybercrime threats

One of Microsoft’s commitments is to bring solutions which can ensure people can be safer and more secure online experiences, especially can be free from illegal, objectionable and unwanted content.

Every single day, there are over 1.8 billion unique images uploaded and shared online. Stopping the distribution of illegal images of sexually abused children is like finding a needle in a haystack.

PhotoDNA is a core element of Microsoft’s voluntary business strategy to protect its customers, systems and reputation by helping to create a safer online environment. The solution has been jointly developed by Microsoft in partnership the US’ Dartmouth College since 2009.

This technology aids in finding and removing some of the “worst of the worst” images of child sexual abuse from the Internet. Microsoft donated the PhotoDNA technology to the National Center for Missing and Exploited Children (NCMEC), which established a PhotoDNA-based programme for online service providers to help disrupt the spread of child sexual abuse material online.

And nowadays, PhotoDNA has become a leading best practise for combating child sexual abuse material on the Internet. PhotoDNA is provided free of charge to qualified companies and developers. Currently, more than 50 companies, including Facebook and Twitter, non-governmental organisations and law enforcement agencies, are using PhotoDNA.

PhotoDNA technology converts image into a greyscale format with uniform size, then divides the image into squares, and assigns a numerical value that represents the unique shading found within each square

Together, those numerical values represent the “PhotoDNA signature” or hash of image, which can then be compared to signatures of other images to find copies of a given image with incredible accuracy and at scale.

PhotoDNA technology can’t be used to identify a person or an object in an image. It’s not facial recognition software. A PhotoDNA hash is not reversible, and therefore can not be used to recreate an image. Microsoft has provided PhotoDNA for free to help fight online child exploitation and is limited to photos at this time. PhotoDNA is only used to identify child sexual abuse materials.
