Identifying the Smartphone Feature


The scenario described in the question involves a smartphone that requires the user to draw a pattern after it has been inactive for more than 20 seconds. This feature is known as a screen lock, which enhances the security of the device by preventing unauthorized access when not in use.


Screen locks can take various forms, including:



  • Pattern locks: Users draw a specific shape on a grid.

  • PIN codes: Users enter a numeric code.

  • Passwords: Users type a word or phrase.

  • Biometric methods: Such as fingerprints or facial recognition.

A firewall protects devices from malicious internet traffic, while biometric identification methodically uses unique human characteristics for access. Therefore, in this context, a screen lock is the most fitting answer.
