What’s the best way to include Biometrics within Blockchain technology?

3 min readAug 31, 2021


We have been using human behavioral data to train Artificial Intelligence for ages now. It gives us potency and decent user experiences. Due to this, online forums use CAPTCHA to discover if the user is human or bot. Today, Blockchain is rising as a broadly used technology for financial transactions, causing an increase in cyberattacks too. By combining biometrics with Blockchain technology, we can build a unique security system for our finances.

Let us see the best way to include Biometrics within Blockchain technology:

Understanding biometrics

Biometrics refers to body measures and analyses associated with human traits. Biometric identifiers define individuals and label them as per their unique characteristics. We can classify these characteristics as physiological aspects of an individual, referring to the body shape.

Additional examples involve fingerprint, DNA, palm print, palm veins, face recognition, hand geometry, retina, iris recognition, and even body odor or scent.

Behavioral characteristics imply the behavioral pattern of a person, comprising signature, typing rhythm, voice, gait, keystroke, and behavioral profiling. Developers are in continual trials for including these solutions in Blockchain technology.

How to include Biometrics within Blockchain technology?

Biometric sensors are highly in use in places where security and privacy are significant. For example, implementation of fingerprint scanning tools to unlock doors.

By including Biometrics within the Blockchain, developers can formulate solutions to provide robust security to a user’s identity in a DLT system. It will allow complete human control. Biometrics such as voice signals and heartbeats could keep hackers from stealing a user’s identity in the financial area.

For instance, a voice signal combined with respiration can give essential data regarding our vocal cords, speaking volumes, and body shapes; Simultaneously, it could use the voice density as an encryption key.

It is quite possible to implement these elements and put conditions for accessing the Blockchain. It will simply be a pass/fail test to check whether the user is a human or not, with no need to disclose one’s identity. In simple words, developers can build a condition test to verify users via physiology.

In addition, measuring heartbeat can give data regarding the electronics of our heart muscles. This data can plausibly show the neuro-anatomy of our heart muscle.

Furthermore, any muscle in our body and its action directly connects with the nerve system. It can give rise to new opportunities for more precise Biometric security solutions for Blockchain.

Importance of Biometrics in Blockchain

Though Blockchain technology offers a secure protocol, it does not specify the real-world owner of the data and who is using it. It simply encrypts information into keys.

Hence, developers are proposing a Biometric Blockchain protocol that explicitly encompasses the Biometric codes of people. It can identify the producers and users in a Blockchain-based system.

This advancement can especially be helpful in food logistics to maintain security and accountability. The need gets stronger as, due to a report, incorrectly labeled food items resulted in the death of an individual during a flight. Hence, using Biometric Blockchain in food logistics is very important and advantageous. It will efficiently specify and check whether data is correct and authentic on a label. At the same time, one can track accountable individuals behind particular data or labels.

This way, a Biometric Blockchain solution will remarkably ease the challenges and risks related to food logistics, like artificial foods or untrue ingredient tags. You can opt to learn Blockchain technology to clear your concepts on this matter.

Closing Thoughts

Biometrics can come out to be an incredibly efficient solution for Blockchain security. Linking a set of fingerprints to your digital wallet will ensure that only you can ever access your account. Besides, Biometric sensor modules implementation in traditional institutions will not only give protection; it will also make cryptocurrency transactions even quicker than standard options, like cash or debit cards using the quick scanning capability of the sensors.
