Good Guy Google is taking a step to end easy access to child pornography on the web as political pressure increases. Google has announced that its engineers are working on an industry-wide database to store information about images that have been flagged as child pornography. This database would include metadata about the image and a hashed signature of the image, allowing the file to be easily identified by others and removed.
The hashing idea allows duplicate images to be easily identified across multiple websites without a human having to identify the image as child pornography. There could be a few issues with the system, however, as one could easily manipulate a pixel or two to change the signature of the image. Google has probably thought of this and maybe even come up with a solution, but we don't know for sure.
Google has also announced a $2 million fund for independent software developers who work on solutions to end the circulation of child pornography.
