Alphanumeric Passwords Becoming History: How Advanced Tech is Shaping Security

The days of simple alphanumeric passwords might be becoming the security of the past. Numerous advanced methods of enhancing security have been developed over the recent years, which has resulted in more effective and greater digital security for sensitive information.

For example, biometrics refer to the statistical analysis of genetic data and are becoming incorporated into security infrastructures to strengthen many facets of security, both physical and digital. Take the ride-calling service Uber – the company asks drivers to take a picture of themselves before beginning their day of driving. Uber’s application then passes the picture through Microsoft’s cloud-based Cognitive Services software tool for verification. This program utilizes an algorithm to compare the face in the picture with the face on file. The facial recognition technology authenticates the individual in possession of the car being used and provides better safety for riders using the service.

MasterCard has also launched an application entitled Identity Check Mobile, which asks customers to verify their identification by taking a photo. This application also requests users to blink in order to show that the individual is animated and not a simple reproduction of a photo if anyone was to submit a fraudulent photograph.

Some other evolving forms of authorization are fingerprint sensors and eye scanning.

A device called the “Intelligun” has a system which automatically locks the firearm when not in use and only unlocks when the owner places their finger over the fingerprint sensor. Current iPhones also have a fingerprint sensor for accessing devices when pressed, which goes to show the effectiveness of fingerprint authorization.

Some airports are actually utilizing iris scans in order to ease traveling. Travelers coming or going from different countries do not have to show their passport as long as they can scan their eyes. Iris scans provide an incredibly precise and accurate way of authenticating travelers throughout a multitude of flights.

Simply put, technological advances such as retinal scans or fingerprint sensors might eventually make the alphanumeric password system obsolete. For the time being however, a combination of all three methods would provide the largest amount of security and protection in all cases.
