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.

Abstract: The present invention provides a method and system for assessing a password based on characteristics of a physical arrangement of keys of a keyboard. A password including unique characters is stored. For each unique character of the password, a character key of the keyboard which denotes the unique character of the password is determined. A positive flag is assigned to each determined character key of the keyboard. A null flag is assigned to each key of the keyboard that is not one of the determined character keys. A key detection frequency is computed for each key vector of the keyboard. A maximum key detection frequency is determined from among the computed key detection frequencies of the key vectors. The maximum key detection frequency is compared with a threshold key detection frequency, from which it is ascertained whether the maximum key detection frequency is at least the threshold key detection frequency.
