Privacy: Respecting an individual's right to control access to their personal information. It's like having your own private room where you can decide who can enter and who cannot.
Anonymity: When participants' identities are unknown even to the researcher. It's like using a code name instead of your real name in a spy mission.
Data Protection: Safeguarding participant data from unauthorized access or use. It's similar to putting a lock on your diary so only you have access to its contents.
