A good security token is one that matches you distinctly and that no one could possibly know, guess, or copy. This is why security experts suggest us to use long and random passwords for our security. However, it is not as easy as it seems because it becomes difficult to memorize strong and unique passwords.
Biometric technology as we know right now is the preferred technique to secure any place. It had to happen counting that it’s such a trouble-free way of security than that of passwords that we have to remember. In biometrics, fingerprints or thumbprints not only make our work easier, but are also unique in nature.
Also, biometric technology has eliminated the hacking problem considering that it is no child’s play for someone to hack your fingerprint rather than cracking the passcode. Following security best practices, setting strong passwords for separate devices and then memorizing them every time is not an easy thing compared to biometrics.
So if a biometric system looks so much better in every department, why is there a need for improvements? Why is technology still not the clever substitute for pesky passwords?
First, it is certain that biometrics will play an important role in future validation. But we must understand that the system is not a cure for everything at the moment. There are still many problems that need to be solved to make the technology completely invulnerable.
Many researchers around the world have said that it’s not exactly true that biometrics can’t be rehashed as they have tried to trick fingerprint readers and have successfully bypassed digital scanners via a special pair of glasses. Also, the initially instigated biometrics keep all data stored on the server rather than limiting it to the client, so it’s not impossible to break the security system in this case.
Last year it was reported that the touch IDs of millions of government employees were stolen from a US office of human resources management, which initially raised suspicions about the technology. Realizing the threat immediately, mobile phone companies quickly modified the fingerprint system in devices by adding a security password following the Touch ID.
This data breach made it clear that biometrics aren’t flawless. In reality they just avoided passwords. Counting can become very problematic if someone fails to log in with their Touch ID, all software companies ranging from Microsoft’s Windows 10 and Google’s Android have also provided a password tool to ensure this doesn’t happen.
Therefore, it is currently not recommended to rely on biometric authentication as having a backup in the form of a password is very important. This process is called multi-factor authentication (MFA) where we can enter biometrics as one of the two-way security procedures, while passwords are the other.
Biometrics is indeed a fantastic method of verification, but the technology is still not completely foolproof. Therefore, it should not be considered a full-fledged replacement for passwords, but should instead be implemented alongside it for enhanced security.
