Cyber Security- ID Theft

Digital ID Theft was almost non-existent in 1997. There were 1.4 million identity reports received by the FTC in 2020. What is Identity Theft and how can I reduce my digital footprint? How can I tell if my P.I.I., Personally Identifiable Information has been compromised? What's the difference between a "fraud" alert and a credit freeze? How can I check to see if a phone number is legitimate without calling the number? Are there proactive steps I can take, such as a software like "LifeLock?" Who do I call if I think or am sure I've had my ID stolen? All of these questions will be answered. Please bring your questions, suggestions, cell phone or laptop.
