Biometric authentication and identification have proven to be helpful technological development in recent years. We use these features on our mobile devices and other appliances. But cryptography can make it much better and safer.
As good as they have been, they have some limitations. Consider the following example.
A company enabled some biometric employee monitoring and management system with the aim of ensuring workers are doing exactly as they should. Once it is installed, there is no telling what the organization can do with this ability. They may be able to track more than just the work activities of the employees.
And this is just one example of the limitations of biometric and identification systems in place today.
The question then is; what can help improve this system? The answer is cryptography.
Cryptography is a way of keeping information secret by using codes and mathematical techniques. Biometric authentication and identification use things like fingerprints, face recognition, and voice recognition to verify that someone is who they claim to be.
It can be used in biometric authentication and identification to make sure that the information that’s being used to identify you is kept private and secure. For example, if you use your fingerprint to unlock your phone, cryptography can be used to make sure that your fingerprint data is kept secret and can’t be accessed by anyone else.
It can also be used to make sure that your biometric information is stored securely. Biometric data is sensitive information, and it’s important to keep it private and protected. Cryptography can help to ensure that your biometric data is kept safe from hackers or other people who might try to steal it, or who should not have access to them.
In short, cryptography is an important tool that can be used to keep your biometric data safe and secure, so that you can use it to verify your identity without worrying about your personal information being compromised.
Cryptography even takes it a step further with zero knowledge proofs. You can be able to prove that you are who you say you are without having to give out any unnecessary information. You can be able to prove that you are actually at work and doing what is required without having to give out some other information you wish not to disclose.

Three of the sectors that will benefit most from cryptographic authentication systems are:
- Law enforcement
- Travel
- Healthcare
As things progress and evolve, a lot of conversations will be had around this topic, leading to positive outcomes for mankind
