Generative image (p5.js, php, MySQL)
Each time you open any page on the Internet, different characteristics of your device (User Agent, IP, Cookie, etc.) are transmitted to the server. With this information, the server can create a unique footprint of your device, assigning it an ID to further identify you.
Based on the information received from your device, a program on the server writes the digital footprint to a database and, thanks to the p5.js library, visualizes it as an animated generative image. Thus, if you scan the QR code, your device becomes a co-author in the creation of their digital footprint.
