A new experiment showed how faces generated by artificial intelligence were indistinguishable from actual human faces. If that's not exciting (or scary) enough, the humans involved in the study also found AI-generated faces to be more trustworthy. As deep fakes become more common on social networking portals, watchdogs and critics alike are urging specialists to take note of its dangers - especially in crime. The two researchers also urged caution against AI-synthesised text, audio, video, and image that are used to commit fraud and propaganda. The study was published in Proceedings of the National Academy of Sciences USA and its co-author Hany Farid, a professor at the University of California, Berkeley was quoted by Scientific American as saying the following - "We found that not only are synthetic faces highly realistic, they are deemed more trustworthy than real faces... these faces could be highly effective when used for nefarious purposes."
