"Privacy protection is a growing concern in the digital era, with machine vision techniques widely used throughout public and private settings. Existing methods address this growing problem by, e.g., encrypting camera images or obscuring/blurring the imaged information through digital algorithms. Here, we demonstrate a camera design that performs class-specific imaging of target objects with instantaneous all-optical erasure of other classes of objects. This diffractive camera consists of transmissive surfaces structured using deep learning to perform selective imaging of target classes of objects positioned at its input field-of-view. After their fabrication, the thin diffractive layers collectively perform optical mode filtering to accurately form images of the objects that belong to a target data class or group of classes, while instantaneously erasing objects of the other data classes at the output field-of-view."
This only works for the privacy-minded, naive among us. If you want to exclude something from a picture or video. Do NOT record it, at all, EVER! If it can record anything it can record the wrong thing.
- freedude 4y agoWhat happens when a camera can't be used in a location that needs added "security" (which is really surveillance and not security) but it cannot be used due to expected privacy reasons (bathrooms, locker rooms, fitting rooms). The claim is "proven" that it cannot "see" your private parts because it is programmed not too. I guarantee the AI will fail at some point or is vulnerable to some attack. Or what if it is connected to a radar/laser speed enforcement camera and takes your cars photo because it detects the car behind you speeding but it cannot "take" that part of the photo because it mis-detected you as the speeder. This technology is fraught with problems when it comes to evidence in a court of law. What is not there is just as important as what is there and if you are erasing what is there you are also erasing what is not there?
