• Purpose: Verifies human access to restricted content on websites

Key Points

What is Captcha?

• Definition: Completely Automated Public Turing test to tell Computers and Humans Apart
• Function: Designed to distinguish humans from automated bots

Importance of Captcha

• Security: Protects websites from spam and abuse by ensuring that users are human
• Access Control: Restricts access to sensitive or valuable information

Triggering the Security System

• Security Activation: When unusual activity is detected, the security system is triggered
• Verification Method: Users must complete a challenge to proceed

Resolving Captcha Challenges

• Verification Process: Involves tasks that are easy for humans but difficult for bots
  • Examples: Identifying objects in images, solving puzzles, simple questions
• Outcome: Successful completion verifies the user as human, granting them access

Conclusion

• Captchas are a critical security measure used to protect online resources.
