System and method for information management using handwritten identifiers
First Claim
1. A method for information management, comprising:
- receiving a first image produced from scanning an original copy of a handwritten identifier in response to a first user command;
comparing the identifier to a set of prerecorded identifiers;
adding the identifier to the set of prerecorded identifiers, if the identifier shares less than a predetermined similarity with any identifier within the set of prerecorded identifiers;
linking the identifier to a set of information;
receiving a second image produced from scanning the original copy a second time in response to a second user command;
matching the second scan of the original copy with the first scan of the original copy;
retrieving the set of information in response to the matching;
computing a signature of the identifier; and
requesting a new identifier if the signature shares more than a predetermined similarity with a prerecorded identifier;
wherein computing includes selecting a set of identifier features for the signature which are scale and rotation invariant.

Abstract
The method discloses: scanning an original copy of a handwritten identifier; comparing the identifier to a set of prerecorded identifiers; adding the identifier to the set of prerecorded identifiers, if the identifier shares less than a predetermined similarity with any identifier within the set of prerecorded identifiers; linking the identifier to a set of information; scanning the original copy a second time; matching the second scan of the original copy with the first scan of the original copy; and retrieving the set of information in response to the matching. The system discloses: a computer system; a handwritten identifier; an imaging device for scanning an original copy of a handwritten identifier; an image processing and matching module for comparing the identifier to a set of prerecorded identifiers; a linking module for linking the identifier to a set of information.

16. A method for information management, comprising:
-
partitioning a set of prerecorded identifiers into a predefined set of groups; selecting one of the predefined groups; scanning an original copy of a handwritten identifier in response to a first user command; comparing the identifier only against prerecorded identifiers within the selected group; adding the identifier to the set of prerecorded identifiers, if the identifier shares less than a predetermined similarity with any identifier within the selected group ; requesting a new identifier, if the identifier shares more than the predetermined similarity with a prerecorded identifier in the selected group; linking the identifier to a set of information; scanning the original copy a second time in response to a second user command; matching the second scan of the original copy with the first scan of the original copy; retrieving the set of information in response to the matching; and effecting actions associated with the set of information.
