Do you struggle to remember complex and unique codes for all of your accounts and devices? This is one of the most common frustrations people have in the digital era, which often results in people recycling the same weak credentials. Whilst this might make it easier to remember, it also puts your sensitive data at risk. These days, biometric security is not a futuristic concept but a practical solution that removes the burden of memory from the authentication process.
Why Physical Traits Beat Digital Codes
A physical attribute offers much stronger security than a text-based password or numerical code. Hackers find it incredibly challenging to replicate a fingerprint or an iris scan compared to cracking a password/code that is often easy to work out, whether it is the user’s birthday or something like “1,2,3,4”.
There are also speed advantages to using biometrics, as you can unlock your phone or bank app instantly with a quick glance or by placing your finger on the sensor rather than typing out a long string of characters.
The Privacy Trade-Off You Face
There are clear benefits to biometrics in terms of convenience, speed, and security, but there is a trade-off to be aware of. The permanent nature of biological data means that there is a privacy concern, whether this is your fingerprint, face, voice, and/or eyes. If a cybercriminal steals your password, you can simply reset it, but this is not so straightforward if they steal your biometric data, as this cannot be changed.
While biometrics secure the device access point, the storage of this immutable data creates new privacy risks if companies fail to protect their databases. You often hear of businesses having their databases hacked and their accounts compromised, which is even more of an issue when it involves biometric data.
Layering Your Mobile Defence
For many people, the privacy trade-off is worthwhile for the benefits of biometrics. If you decide to go down the biometrics route, it is smart to combine this with other privacy tools for complete protection. While Face ID stops a thief from unlocking a stolen phone, it does not encrypt data sent over public Wi-Fi networks. Installing a free VPN for iPhone ensures that the traffic leaving the device remains as secure as the biometric lock protecting the screen. This can provide comprehensive protection and peace of mind.
Biometric security is no longer a futuristic concept and is one of the best ways to protect your devices and data. Biometrics can offer a high level of security as well as speed and convenience, but it is important to be aware of the privacy concerns. You cannot change your biometric data, so it is important to be aware of the risks of using this form of verification. When combined with other methods, it can provide strong protection and reassurance.
