You believe this is easy when the device has multiple recording sensors and multidimensional information (such as spatial information, changes in focus sensors durning recording, etc) is part of recording that is digitally signed?
- free_bip 2y agoWho's proposing such a device to get widespread adoption? I've heard of sensor data signing [1] but not what you're describing. [1] https://pro.sony/ue_US/solutions/forgery-detection https://pro.sony/ue_US/solutions/forgery-detection
- czl 2y agoThe concept of sensor data signing to authenticate videos and images captured on mobile devices is still an emerging technology, not yet widely adopted. However, as AI-generated synthetic media becomes more prevalent and potentially problematic, solutions like this may gain traction. The key idea is to leverage the array of sensors built into modern smartphones and tablets - accelerometer, gyroscope, GPS, WiFi/cellular signal data, etc. - to cryptographically sign the sensor readings along with the visual data itself at the time of capture. This extra layer of verifiable sensor data would help establish that a recording originated from a real physical device in a particular place and time, as opposed to a purely digital fabrication. Historically, technologies like digital signatures and public key cryptography started out in niche military/government applications before becoming ubiquitous in the computer era. In a similar way, sensor-level authentication of audiovisual media could follow an adoption curve driven by the growing need to combat sophisticated AI forgeries.
