1. A method for private personal identification number (PIN) management, comprising:
- ascertaining whether a first delay period of a preceding PIN has expired wherein said delay period of said preceding PIN is a period of time that must expire before a current PIN can be received, and said first delay period greater than zero if upon said preceding PIN does not matching a validated PIN, said first delay period equal to zero if said preceding PIN matches said validated PIN;
receiving a said current PIN after at least expiration of said first delay period; and
determining whether said current PIN matches said validated PIN; and
delaying for changing said a second delay period to a new delay period longer than said delay period for said preceding PIN if upon said current PIN does not matching said validated PIN, and transferring to said ascertaining, said second delay period greater than said first delay period wherein said current PIN becomes said preceding PIN and said new delay period is said delay period of said preceding PIN upon said changing transferring to said ascertaining so that when said current PIN does not match said validated PIN, before receipt of an another access attempt is permitted said delay period is increased in duration with each successive failed access attempt.

Abstract
A method for private personal identification number (PIN) management comprises ascertaining a first delay period of a preceding PIN. The first delay period is greater than zero if the preceding PIN does not match a validated PIN and the first delay period equals zero if the preceding PIN matches the validated PIN. The method also includes receiving a current PIN after at least the first delay period and delaying for a second delay period if the current PIN does not match the validated PIN. The second delay period is greater than the first delay period.

3. A method for private personal identification number (PIN) management, the method comprising:
-
determining whether a delay period for receiving a request for a service has expired; receiving a first said request for a said service having restricted access upon expiration of said delay period, said first request comprising a first PIN entered by a user; matching said first PIN with another second PIN that has been validated; allowing access to said service based at least on said matching; incrementing an exponent if upon said first PIN does not matching said another second PIN; and delaying for a said delay period that is based at least on said exponent if upon said first PIN does not matching said another second PIN; and repeating said determining, said receiving, said matching, said incrementing wherein said incrementing increments said exponent, and delaying until said matching finds a match so that when said PIN does not match said another PIN, before receipt of an another access attempt is permitted, said delay period is increased exponentially in duration with each successive failed access attempt; and allowing access to said service based at least on said matching. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A method for private personal identification number (PIN) management wherein the method allows access to any service that is not PIN-protected, the method comprising:
-
receiving a first access request for a service, said first request comprising a first PIN entered by a user; allowing access to said service if said service is not PIN-protected; determining a PIN status if when said service is PIN-protected, said determining including delaying for a delay period, which that increases exponentially with each successive failed access request, before receiving another access request; and allowing access to said service based at least on said PIN status it when said service is PIN-protected. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. A program storage device readable by a machine, embodying a program of instructions executable by the machine to perform a method for private personal identification number (PIN) management, the method comprising:
-
ascertaining whether a first delay period of a preceding PIN has expired wherein said delay period of said preceding PIN is a period of time that must expire before a current PIN can be received, and said first delay period greater than zero if upon said preceding PIN does not matching a validated PIN, said first delay period equal to zero if said preceding PIN matches said validated PIN; receiving a said current PIN after at least expiration of said first delay period; and determining whether said current PIN matches said validated PIN; and delaying for changing said a second delay period to a new delay period longer than said delay period for said preceding PIN if upon said current PIN does not matching said validated PIN, and transferring to said ascertaining, said second delay period greater than said first delay period wherein said current PIN becomes said preceding PIN and said new delay period is said delay period of said preceding PIN upon said changing transferring to said ascertaining so that when said current PIN does not match said validated PIN, before receipt of an another access attempt is permitted said delay period is increased in duration with each successive failed access attempt. - View Dependent Claims (48)

49. A program storage device readable by a machine, embodying a program of instructions executable by the machine to perform a method for private personal identification number (PIN) management, the method comprising:
-
determining whether a delay period for receiving a request for a service has expired; receiving a first said request for a said service having restricted access upon expiration of said delay period, said first request comprising a first PIN entered by a user; matching said first PIN with another second PIN that has been validated; allowing access to said service based at least on said matching; incrementing an exponent if upon said first PIN does not matching said another second PIN; and delaying for a said delay period that is based at least on said exponent if upon said first PIN does not matching said another second PIN; and repeating said determining, said receiving, said matching, said incrementing wherein said incrementing increments said exponent, and delaying until said matching finds a match so that when said PIN does not match said another PIN, before receipt of an another access attempt is permitted, said delay period is increased exponentially in duration with each successive failed access attempt; and allowing access to said service based at least on said matching. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61)

62. A program storage device readable by a machine, embodying a program of instructions executable by the machine to perform a method for private personal identification number (PIN) management wherein the method allows access to any service that is not PIN-protected, receiving a first access request for a service, said first request comprising a first PIN entered by a user;
-
allowing access to said service if said service is not PIN-protected; determining a PIN status if when said service is PIN-protected, said determining including delaying for a delay period, which that increases exponentially with each successive failed access request, before receiving another access request; and allowing access to said service based at least on said PIN status if when said service is PIN-protected. - View Dependent Claims (63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92)
