The conventional typed password is essentially a thing of the past when it comes to the strides researchers and developers have made for more fool-proof alternatives; for example, SkullConduct. SkullConduct is the name given by researchers in Germany who have been experimenting with skull vibrations as a form of authentication. When sound passes through a person's skull, a unique pattern is created just for them.
To read this specific pattern, researchers modified Google Glass to play white noise. The Google Glass application then records the sound it plays and converts the data into byte files that were used to identify 10 participants. SkullConduct was 97% accurate. Although many more tests are in store to address issues such as background noise, SkullConduct is an promising concept.
