20130269010PATTERN ENTROPY PASSWORD STRENGTH ESTIMATOR - A password evaluation system is provided for determining the password strength of a password. A password is provided for evaluation. The password is parsed and substrings are identified from the password. Each substring is associated with a pattern that can generate the substring. The substrings are scored to determine a substring strength measure for the substring. The substrings are combined to identify non-overlapping substring combinations, which together make up the password. The combinations are assigned a combination strength score based in part on the substring strength of the substrings contained in the substring combinations. The substring combination with the lowest combination strength measure is identified and the associated combination strength measure is used as the password strength measure for the password.10-10-2013
