Photoid
Photoid is a technology that allows for the digital embedding of information within photographs. This embedded data, often referred to as a "photoid," can contain various forms of metadata such as location, date, time, camera settings, and even a unique identifier. The primary purpose of photoid technology is to provide a verifiable and tamper-proof way to associate descriptive information with a visual asset.
This technology functions by encoding data into specific, often imperceptible, regions of a digital image file.
