Definitions
- the present disclosure relates to an electronic device including an image sensor according to one embodiment, a method of operating the same, and a recording medium.
- Biometric authentication refers to a technology that uses physical and behavioral characteristics of a person to identify them and grant access to specific systems or data. Unlike traditional authentication methods (e.g., PIN, pattern, password), which require complex settings for enhanced security and are difficult to remember, biometric authentication does not require separate memory and is very convenient for users if it has reliable recognition performance. Due to these advantages, biometric authentication is widely used in many systems that require user authentication, such as bank ATMs and mobile devices. PIN, pattern, and password methods can be easily changed to new PIN, pattern, and passwords if the settings are leaked externally, but biometric data (e.g., face, iris, fingerprint, vein) used in biometric authentication cannot be changed once leaked externally and the damage can be permanent. For this reason, it is very important to safely protect biometric data used in biometric authentication.
