Final answer:
Encryption is used to secure data in various contexts, such as secure online communications where services use end-to-end encryption, businesses protecting sensitive customer data, and governments safeguarding classified information.
Step-by-step explanation:
Encryption is a critical technology used to secure data by scrambling it into an unreadable format that can only be deciphered with the correct key. Here are three detailed examples of where encryption is deployed:
- Secure Online Communications: Applications like What s App and Signal use end-to-end encryption to ensure that messages can only be read by the sender and receiver, not even by the companies that run these services.
- Data Protection for Businesses: Financial institutions encrypt customer data to protect sensitive information such as bank account numbers and personal identification information from data breaches and cyberattacks.
- Government Security: Governments use encryption to secure classified information, helping to prevent espionage and protect national security by ensuring that sensitive data is not accessed by unauthorized individuals or states.
These examples demonstrate encryption’s effectiveness in securing personal, financial, and national data against unauthorized access and potential misuse.
