Blockchain – Secured Biometrics

In recent years Blockchain has been one of the top-notch technology topics, since Bitcoin applied this in 2009 with it’s cryptocurrency, with unique features such as P2P communication method, time stamp feature and a unique record of data characteristics, it has become the most secure transaction method that exists. Blockchain can not be hacked in any sense, the information contained on format blocks was standardized and no extra information could be added in the block and this created a limitation between biometrics and Blockchain.


Ethereum is the concept of Blockchain 2.0 that now it is not only working with cryptocurrency but with all kind of services by sticking to a new concept of “attachment” in blocks, with this new update users may add more information into the blocks and due this generating a new concept named “Token” and this will be the a significant part of the interaction between biometrics and Blockchain.

In this post we are going to explain what is Blockchain, how it works and how it Is associated with Biometrics.

Blockchain is a way of passing information in an automated and safe manner from A to B. First one initiates the whole process by creating a block and this block is verified by different computers around the net and then is added to a chain stored across the net creating an individual record and history.
Biometrics is the best way for identify recognition but in most advanced regions biometrics technology reception has been slower than expected and this is where Blockchain is related because it may seem the end of this issue.

Otherwise stated biometric compliances will not save biometric templates and this template will be kept in the Blockchain and consecutively will be stored in cloud servers. Users will be assigned a “Token” to access to its own biometric block without this “Token” the user won’t have access.
