Techuila's Post

30,000 dots between you and a hacker. 🛡️💻 Ever wondered why a high-def photo of you can’t trick your iPhone? It’s because FaceID isn’t actually “looking” at you—it’s “feeling” you. Here’s the genius tech behind that little notch: 1️⃣ The Dot Projector: The second you wake your phone, it projects 30,000 invisible infrared dots onto your face. 2️⃣ The 3D Map: It’s not a flat image; it’s a topographic map. It reads the curves of your nose, the depth of your eyes, and the structure of your jaw. 3️⃣ The “Fake” Check: A photo is 2D. When those 30,000 dots hit a photo, they stay flat. But on your face, they deform. If the “math” doesn’t match your 3D profile... Access Denied. 🚫 It’s basically an invisible laser show happening every time you want to check your DMs. Distilling the tech you use every day. 🍹✨ #Techuila #AppleTech #FaceID #CyberSecurity #SystemDesign WomenInTech AestheticTech SoftwareEngineering
