Editorial: Geographical Memory
The way it works is pretty simple: the user selects a location that is particularly memorable to them and draws a boundary around that location. Next, the image is 'salted' with a string of random characters and numbers that are unique to the user. Even in the case of various users choosing the same location, the characters assigned are different. Thus, the end result is a nearly impenetrable password that only the user knows. This is yet another attempt at mitigating the problems associated with memorizing several lengthy passwords for various websites. Biometrics are one way to go, but the incredible ease with which the brain remembers visual cues is a direction that is only now being explored.
