Abstract
A method and computer for assessing whether a password can be generated by using characteristics of a physical arrangement of keys of an input device. A received password includes characters corresponding to respective select keys in a sequence of select keys of the input device. For each select key, a final detection frequency is calculated as a sum of an initial detection frequency and an additive correction. A password determination value is calculated as a ratio of a total number of select keys having a final detection frequency equal to a minimum detection frequency and the total number of select keys in the sequence of select keys. A determination of whether the calculated password determination value is, or is not, less than a predetermined threshold value indicates that the password cannot, or can, respectively, be generated by using the characteristics of the physical arrangement of keys of the input device.
