Biometric technologies are so common these days. Biometric refers to biological measurements that can be used to identify you uniquely. Biometric technology is used to enhance the security of personal data. There usually are three kinds of biometrics, including biological, behavioural, and morphological. Behavioural biometrics incorporate traits like your way of walking, sitting posture, the shape of your ear, your voice, the veins in your hands, and how you smell; these can be mapped for use with a security scanner any place, including the sizzling hot spot casino. Biological biometric uses your genetic and molecular makeup and it requires a sample of your blood or another body fluid for assessment. Morphological biometrics involves the body's structure, including your fingerprints and facial shape.

How Can Biometrics Offer Security?

One thing that makes biometrics work is a simple fact that our unique physical features are pretty fixed. Your biometric data can be used to replace passwords for things like phones, computers, buildings, and other things that require authorized access. The only thing that is needed first is your biometric data. It is usually mapped and saved for future retrieval when you access a service with restricted entry. At that point, a biometric scanner will be used to determine if you are authorized to get in.

Biometric data is then encrypted and kept in a remote server or a safe device. Encryption means that an additional layer of protection is created to hide your data and enhance security. The point we are putting across here is that your body becomes the key to unlock services that you think you are authorized to access with biometrics. Biometric technology is convenient to use and makes it harder for someone to take away your identity or impersonate you. Examples of things that use biometrics include e-Passports, sensitive documents and valuables, phone security systems.

Does Biometrics Cause Identity and Privacy Concerns?

There is the fear that even if biometrics creates strong security, it could expose your privacy. The argument is that biometrics makes it easier to collect personal data, and this could happen even without your permission. Facial recognition cameras are already being used in some airports, especially in Amsterdam and Tampa. The details captured by these cameras will be saved where the owner does not know. Therefore, it is assumed that such data may be used to continually watch the owner, and those keeping it can misuse it.

Biometrics and Data Safety Issues

Even if there is an assurance that biometric data is properly encrypted and stored, some people think it’s not secure. Hackers and other cybercriminals can target the database. Some people will consider such information safer in their iPhone’s Touch ID than in a third-party service provider who promises to encrypt data.

How Can Biometric Identity Be Protected?

Biometrics have some privacy and security issues. It is necessary to do something that can limit unauthorized access. When a system uses multiple authentication methods, unauthorized access can become harder; one of the suggested ways includes Life detection, such as blinking. Extra security features like gender, height, and age can be added to biometric data to keep it safer. Two-factor authentication can also be used to keep your details more secure and private.
