Reverse mapping method and apparatus for form filling
View Patent ↗In the presently preferred embodiment of the invention, every time a user submits a form the client software tries to match the submitted information with the stored profile of that user. If a match is discovered, the program tags the field of the recognized data with a corresponding type. The resulting profile can be used after that to help all subsequent users to fill the same form.
1. A method for downloading a user's profile in a reverse mapping form fill application without challenging said user with a higher level of authentication, comprising the steps of:
encrypting said user's profile with a user specific symmetric key, stored in a user database;
storing said encrypted profile on said user's system after a first time said user authenticates with a higher-level authentication from said user's system;
using less than every character from said user's profile when subsequently downloading said user profile from said user's system;
revealing only a subset of said user's profile, while obtaining sufficient confidence in said user's profile to generate a reverse mapping; and
responsive to obtaining said sufficient confidence, generating said reverse mapping.
2. A method for downloading a user's profile in a reverse mapping form fill application without challenging said user with a higher level of authentication, comprising the step of:
using less than every character from said user's profile when downloading said user's profile from said user's system;
revealing only a subset of said user's profile, while obtaining sufficient confidence in said user's profile to generate a reverse mapping; and
responsive to obtaining said sufficient confidence, generating said reverse mapping.
3. An apparatus for downloading a user's profile in a reverse mapping form fill application without challenging said user with a higher level of authentication, comprising:
a module for encrypting said user's profile with a user specific symmetric key, stored in a user database;
a memory storing said encrypted profile on said user's system after a first time said user authenticates with a higher-level authentication from said user's system;
a module for using less than every character from said user's profile when subsequently downloading said user's profile from said user's system;
a module for revealing only a subset of said user's profile, while obtaining sufficient confidence in said user's profile to generate a reverse mapping; and
a module, responsive to obtaining said sufficient confidence, for generating said reverse mapping.
