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.

Claims

1. An apparatus, comprising:

a computer device that accepts information which has been entered as entered access information;

said computer device comparing said entered information which has been entered with stored information to determine if said entered information matches exactly with the stored information,

said computer device operating if said entered information matches exactly with the stored information to accept said entered information,

said computer device operating if said entered information does not match exactly with the stored information to first compare a first part of the entered information with at least one section of the stored information and to second compare a second part of the entered information, representing a separate part of the information than said first part, with at least one other section of the stored information different than the at least one section, and to determine at least one distance between the parts of the entered information and the sections of the stored information, and based on said at least one distance being determined by said first compare and said second compare carried out by said computer device, to accept the entered information when the entered information does not match exactly with the stored information, based on the distance being less than a specified amount,

said computer device providing access to at least one computer function responsive to accepting the entered information.

2. An apparatus as in claim 1, wherein said first compare and said second compare compares patterns of the parts with patterns in areas of the stored information.

3. An apparatus as in claim 2, wherein letters and locations in the parts are compared against letters and locations in the stored information.

4. An apparatus as in claim 2, wherein neighborhoods in the parts are compared against neighborhoods in the stored information.

5. An apparatus as in claim 1, wherein said parts are n letter groups forming the parts that are compared against corresponding n letter groups in the stored information.

6. An apparatus as in claim 1, wherein said first compare and said second compare are relationships that take into account an analysis of common keyboarding errors.

9. An apparatus as in claim 1, wherein said entered information is a pattern of information entered into a user interface.

7. An apparatus, comprising:

a computer device that accepts information which has been entered as entered access information;

said computer device comparing said entered information which has been entered with stored information to determine if said entered information matches exactly with the stored information,

said computer device operating if said entered information matches exactly with the stored information to accept said entered information, said computer device operating if said entered information does not match exactly with the stored information to first compare a first part of the entered information with at least one section of the stored information and to second compare a second part of the entered information, representing a separate part of the information than said first part, with at least one section of the stored information, and to determine at least one distance between the parts of the entered information and the sections of the stored information, and based on said at least one distance being determined by said first compare and said second compare, to accept the entered information when the entered information does not match exactly with the stored information,

said computer device providing access to at least one computer function responsive to accepting the entered information, wherein said computer device determines a least mean squares difference between the entered information and the stored information, and computer determines a match from an amount of said least mean squares difference.

8. An apparatus as in claim 7, wherein said computer determines said match from an amount of least mean squares difference that represents a match of 80% or better.

10. A computer readable non-transitory storage medium containing a set of instructions for a general-purpose computer, the set of instructions comprising:

instructions to obtain first information which represents a user'"'"'s access to an access-controlled item on the computer;

instructions to compare the first information with at least one stored item of information representing authorized access information;

where said instructions to compare comprise comparing a pattern of the first information, with a pattern of the stored item of information and instructions to accept the first information to provide said access when said pattern of said first information matches said stored item of information, wherein said instructions to accept comprise providing said access when said pattern of said first information is not exactly the same as the stored item of information, but a least mean squares distance between said pattern of said first information and said pattern of said stored item of information is less than a specified non-zero value.

11. A computer based apparatus comprising:

a computer having a user interface which controls entry of first information, said first information which represents a user'"'"'s access to at least one access-controlled resource on the computer, said computer having a processor which operates to compare said first information with at least one stored item of information representing authorized access information, by comparing a pattern of the first information as entered, with a pattern of the stored item of information and said computer operating to accept the first information to provide said access when said pattern of said first information matches said stored item of information, wherein said computer operates to provide said access when said pattern of said first information is not exactly the same as the stored item of information, but a least mean squares distance between said pattern of said first information and said pattern of said stored item of information is less than a specified non-zero value.

12. A computer based apparatus comprising:

a computer having a user interface which controls entry of first information, said first information which represents a user'"'"'s access to at least one access-controlled resource on the computer, said computer having a processor which operates to compare said first information with at least one stored item of information representing authorized access information, by comparing a pattern of the first information as entered, with a pattern of the stored item of information and said computer operating to accept the first information to provide said access when said pattern of said first information matches said stored item of information, wherein said computer also operates to provide said access when said pattern of said first information does not match said stored item of information, but a distance between parts of said pattern and parts of said stored item of information is less than a specified amount.

13. A computer readable non-transitory storage medium containing a set of instructions for a general-purpose computer, the set of instructions comprising:

instructions to obtain first information which represents a user'"'"'s access to an access-controlled item on the computer;

instructions to compare the first information with at least one stored item of information representing authorized access information;

where said instructions to compare comprise comparing a pattern of the first information, with a pattern of the stored item of information and instructions to accept the first information to provide said access when said pattern of said first information matches a pattern of said stored item of information, wherein said instructions also determine at least one distance between said stored item of information and said first information and said instructions to accept the first information, provide said access when a distance between said stored item of information and said first information is greater than zero, but less than a specified amount in addition to when said pattern of said first information matches said stored item of information.
