First Claim

1. An apparatus, comprising:
- a computer device that accepts a password which has been entered, as an entered password, and compares said entered password with a stored password to determine if said entered password matches with the stored password, said computer device signaling acceptance of the entered password even when the entered password is not exactly the same as the stored password, wherein said signaling acceptance comprises determining a relationship between said entered password and said stored password by correlating portions in the entered password with portions in the stored password, and the relationship is also based on correlating locations of those portions in the entered password with the location of those portions in the stored password, and said computer accepting said entered password if the relationship indicates agreement between the entered password and the stored password by a predetermined amount and signaling the acceptance only when the relationship indicates the agreement by at least the predetermined amount and even when the relationship indicates that the entered password is not exactly the same as the stored password.

Abstract
A technique of allowing entry of the password which is not 100% correct. This password would be used to verify identity and/or login information in low security techniques. The password is scored relative to the correct password. The scoring can take into effect least mean squares differences, and other information such as letter groups, thereby detecting missed characters or extra characters, as well as shift on the keyboard.

5. An apparatus, comprising:
a computer that accepts entry of an entered password which has been entered, and compares said entered password with a stored password and signals acceptance of the entered password based on its comparing the entered password with the stored password even when the entered password is not exactly the same as the stored password, wherein said computer compares said passwords by finding neighborhoods of characters that are common in both of said stored password and said entered password.

6. A system, comprising:
a computer, which stores at least one stored item of information which represents a user'"'"'s access to a resource, and compares said at least one item of information to an entered item of information, which determines differences between said stored item of information and said entered item of information, and accepts the entered item of information based on said differences, even when the entered item of information is not exactly the same as said stored item of information, wherein said computer determines a score related to a difference between said stored item of information and said entered item of information, wherein said score is related to an absolute distance between information in said entered item of information and information in said stored item of information. - View Dependent Claims (7, 8, 9)

10. A computer readable storage medium containing a set of instructions for a general-purpose computer, the set of instructions comprising:
-
instructions to obtain a item of information which represents a user'"'"'s access to a to an access-controlled item which has been entered; instructions to access a database of stored items of information; instructions to compare the entered item of information with at least one item of information in the database; instructions to determine a score representing similarities between the entered item of information and the stored item of information; and instructions to accept the entered item of information based on said score and provide access to the access controlled item even when the entered item of information is not exactly the same as the stored item of information, wherein said score defines a least mean squares distance between parts of said entered item of information and parts of said stored item of information. - View Dependent Claims (11, 12)
