5 Types of Biometric Identification Methods

You’re not alone if you’ve begun to get frustrated with the amount of long, complex passwords that everyday life now requires. From checking your email to checking your bank account balance, passwords are everywhere. However, the end of passwords may be near with these five types of biometric identification methods.

Biometric identification and verification has been slowly introducing itself into our lives and will most likely play an important role in our future. We can currently see biometric technology being applied in several situations such as iris scans in airport security checkpoints, fingerprint scans to gain access to an office building, voice recognition technology within cars, and even fingerprints within schools to manage sensitive student information and transactions. Over the next few years we will start to see more and more biometric recognition technology work its way into our day-to-day routines meaning the possible elimination of passwords all together. Here are just five types of biometric technologies that you may start to see pop up in the near future:

Fingerprint scan: Probably the biometric verification technology that people are the most used to, fingerprint verification plays an important role in police records and forensic science. It’s now close to common place on mobile phones and to gain access to buildings instead of access cards or keys. Once a fingerprint is scanned, the information from the image is then run through algorithms to identify unique points within the fingerprint to look for a match, or in other words, a previously scanned fingerprint within the database.

Iris scan: Something that was once only seen in spy and sci-fi movies, it is now a realistic and viable way of identity verification. Through iris pattern recognition and matching using a biometrics database, iris scans can be performed with just a glance.

Voice verification: Voice verification works by identifying your specific vocal track, or also known as a “voice print”. With voice verification, the user needs to repeat a passphrase which is then compared to a recording previously provided by the user.

Biometric facial recognition: Through a camera, a user’s face is scanned to map out the dimensions and positions of facial features and characteristics. In short, this technology analyzes your face and then compares it to a database of facial images to see exactly who you are if you are already in the database. Biometric facial recognition can be used by airport security to identify anyone who may be on a no-fly list or even on your iPhone to gain access.

Vein recognition: The fact that every person’s circulatory system is unique and that veins are underneath the skin, make vein recognition very difficult to hack. Vein recognition technology is usually used by analyzing the vein patterns of a finger, palm or eye and then of course searching a biometric database for a match.

Each type of biometric verification technology has its strengths and weaknesses, but what is important is that our personal information remains personal and that we don´t fall prey to identity theft or account hacking.  This could mean a future without passwords or a combination of various identification systems to ensure our security.
