Simple four-digit passwords aren’t enough for some people. While these codes are usually enough to protect the average users, some people want higher level security. You have options when you want to secure your smartphone. Other options include retina scanners, fingerprint scans and voice recognitions. All of these are useful, but are they really necessary, and are biometric security options a wave of the future?
Iris scanners are more than just filters that protect mobile devices. Iris scanners are also a part of high-level security areas in government buildings and even a part of Google’s data center security.
Iris scanners use two types of technologies: visible wavelengths and near infrared. Near infrared scanners are more compatible with darker eyes, which are more common since dark eyes are a dominant gene. However, visible wavelengths can identify greater detail in the eye. Combined, these two technologies are perfect for smartphone security. Because your eyes are your own and never change, the future for this technology is solid.
Thumb or Finger Prints
Finger prints are just as reliable as iris scanners, but they are more difficult to detect. The problem with finger print scanners is that they are more easily fooled. Another person can gain access to your finger prints from you touching a glass or other removable item.
Finger print scanners were the topic of Mythbusters, and the show was able to prove that finger print scanners can be tricked more easily.
Alternatives to this type of biometric scanner are a device that picks up on your heart beat and body temperature. However, these too can be fooled.
Voice recognition is even in basic technology. For instance, the iPhone has a program called Siri that lets the user speak commands. The same type of technology is included with voice recognition, but just like finger prints, your voice can also be emulated through recordings and good computer software.
While these biometric security features are an enhancement to the average four-digit pin, the still have the same problem: one point of failure. You can add these features to some phones, but do you really need it, and will the technology be reliable in the future? Instead of adding more complexity to your smartphone and tablets security, keep passwords secure and avoid giving your password to any website you don’t recognize.
