Abstract
A security system controlling access to a resource is arranged to operate such that when an attempt to access a resource using a password or PIN fails, the time interval 't' that must elapse before a subsequent attempt at access can be successful, is incremented. By making the increments increasingly large (illustratively, an exponential function of the number 'n' of unsuccessful attempts), repeated access attempts by hackers or other unauthorized users is discouraged, because they simply cannot wait the time needed to make a large number of trial and error attempts. On the other hand, valid users, while experiencing a delay prior to access, are nevertheless able to gain access, rather than being completely 'lockedout'. This approach is a better compromise between access control and denial.
