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.
