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. When a photoid is present, it can be read by compatible software or devices, which then present the associated information to the user. This can range from simple EXIF data, which is commonly found in digital cameras, to more complex and secure forms of embedded information. The applications of photoid technology are diverse, including use in journalism for verifying the authenticity of images, in supply chain management for tracking goods, and in legal contexts for establishing evidence. The development of photoid aims to enhance the utility and trustworthiness of digital photographs in an increasingly data-driven world.
