Types of Identifiers

When we talk about people, documents, or data, we need a way to refer to them—and that’s where identifiers come in. In this video, we break down: 🔹 What identifiers are and why they matter 🔹 The two main types: assigned identifiers (like student IDs, passport numbers, and serial codes) vs. derived identifiers (like cryptographic hashes and digital fingerprints) 🔹 How derived identifiers help us verify authenticity and integrity of data without relying on a central authority 🔹 Why identifiers are the foundation of databases, digital security, and modern identity systems Whether you’re curious about digital trust, hashing, or identity systems, this video explains the core concepts in simple terms.
