Abstract
Systems and methods may be used for providing more secure authentication attempts by implementing authentication systems with credentials that include interspersed noise symbols in positions selected, for example by a user. These systems and methods secure against eavesdroppers such as shoulder-surfers or man-in-the middle attacks as it is difficult for an eavesdropper to separate the noise symbols from legitimate credential symbols. Some systems and methods may use a subset of a credential with the interspersed noise symbols.
