A biometric is defined as a unique, measurable, biological characteristic or trait which is used to identify individuals. Most widely used biometric characteristics to identify individuals include Face, Fingerprint, Hand geometry, Retina, Iris, Voice etc.
Biometric identification consists of two stages:
• Enrollment: During the enrollment stage, a sample biometric is acquired from the individual. Unique characteristics this sample are then extracted to form a biometric template which is used for subsequent comparison.

• Verification: During the

Most widely used biometric trait for this Biometric Encryption include Fingerprint, Face Recognition, Hand Geometry, Iris Scan, etc.
The key is generated again only if the correct live biometric sample is provided on verification. The digital key (password, PIN, etc.) is randomly generated on enrolment, so that the user (or anybody else) does not even know it. This key is independent of biometric so, it can always be changed or updated. The Biometric Encryption template can be stored either in a database or locally (smart card, laptop, cell phone, etc.). On verification, the user presents their fresh biometric sample (which acts as decryption key), which retrieves the same key or password [2].

Applications of Biometric Encryption:
• Access control
• Biometric ticketing
• Biometric boarding cards for travel
• Identification, credit, and loyalty card systems
• Consumer biometric payment systems etc.

Advantages of Biometric Encryption:
• No retention of the biometric image or template.
• The key is completely independent of biometric thus can easily be changed or updated.
• Single biometric for multiple accounts. 

• There is no need to memorize long passwords.
• Improved security of personal data and communications.
• Greater confidence, trust, and use of biometrics by the public.
Major challenges for Biometric Encryption:
• Loss of individual control over one’s personal data.
• Data matching, surveillance and profiling.
• Significant security risks, especially
