Security Issues Created by What a Computer

Security Issues Created by What a Computer 'Sees'

It’s amazing how computers are learning to recognize objects almost with human ability, but these machines can be fooled by optical illusions according to Cornell researchers at the University of Wyoming Evolving Artificial Intelligence Laboratory. This, of course, raises security concerns.

Researchers created images that look like white noise or random patterns to the human eye where asSecurity Issues Created by What a Computer 'Sees' computers have the ability to identify them as common objects. Through training, computers are shown photos of objects from many different views along with the name of the object associated with it in human vocabulary. As a computer “looks” at the photos, it assembles a model that fits them all and will “learn” to match a new photo of the same object. However, it’s during training that security can become an issue.

Researchers in the Cornell Creative Machines lab started training a computer to recognize an image, but with a twist. They slowly integrated mutated views of the image until eventually the original image was unrecognizable with the human eye, yet the computer was still able to recognize the original image with over 99% accuracy. This test proved that it’s possible to fool a computer into learning something that is not true. Because of this, malicious web pages could include fake images to fool search engines; fake images could be used to bypass safe search filters; or an abstract image may be accepted by a facial recognition system as an authorized visitor.

  • AI Used as Part of Sophisticated Espionage Campaign

    A cybersecurity inflection point has been reached in which AI models has become genuinely useful in cybersecurity operation. But to no surprise, they can used for both good works and ill will. Systemic evaluations show cyber capabilities double in six months, and they have been tracking real-world cyberattacks showing how malicious actors were using AI capabilities. These capabilities were predicted and are expected to evolve, but what stood out for researchers was how quickly they have done so, at scale. Read Now
