7.7:Ethical issues around data collection
-
Privacy Risks: Personal data can be vulnerable to breaches or misuse when stored in systems. Programmers need to protect it.
-
Protection Methods:
- Delete Data: Remove personal info when it’s no longer needed.
- Minimize Data: Only collect essential information.
- Anonymize Data: Use methods like
hashCode()
in Java to hide real info. - Encrypt: Secure data so it can’t be easily accessed even if stolen.
The main goal? Keep personal data safe with smart coding practices.

userData.add("john@example.com");
// Once you're done using the data
userData.clear(); // Removes all entries
userData = _____; //
