Abstract

A method of enhancing online security by requiring the user to choose from among multiple objects presented to the user an object which falls within an abstract object definition previously provided by the user. The presented objects are therefore unknown to the user but include at least one with a particular quality known to the user.

Claims

1. A method of authenticating a request from a user connecting to an authentication service comprising:

storing user information in the form of an abstract definition of a viewable or audible object,

receiving a request from a user to provide authentication objects for that user,

presenting authentication objects to the requester including at least one object falling within the abstract definition,

receiving a verification request identifying the user and one of the presented authentication objects,

verifying whether the authentication object identified is one of those objects presented falling within the abstract definition,

confirming the request as authenticated where the object is correctly verified.

2. A method as claimed in claim 1 wherein the authentication objects are presented to the user simultaneously.

3. A method as claimed in claim 1 wherein the authentication objects are presented to the user sequentially.

4. A method as claimed in claim 1 wherein there is additionally presented to a user an object representing a public code, and the user is required to enter specific parts of the public code, the parts being identified from further user information stored with the authentication service.

5. A method as claimed in claim 1 wherein the authentication objects are presented by one communication means and a public code by another.

6. A method as claimed in claim 1 wherein the user is additionally required to enter an individual password.

7. A method as claimed in claim 1 wherein all data interchanged with the user is sent via a secure communications means.

8. A server providing an authentication service to a user, the server comprising:

storage means for storing a user profile, the profile including a user name and at least one abstract definition of a user object,

serving means for serving objects when a user requests objects to allow verification of a transaction, the serving means serving multiple objects with at least one falling within the abstract definition of the user object,

comparison means for comparing a returned object definition with a user profile abstract definition to determine whether the transaction should be authenticated.

9. A server as claimed in claim 8 wherein the server additionally detects the return of an object or code to authorize a transaction.

10. A server as claimed in claim 8 wherein the server additionally detects the return of an object or code representing a duress code.

11. A method of providing a user interface on a computer screen allowing a user to confirm a verifiable choice of options comprising:

requiring the user to define an abstract object definition,

providing to the user multiple objects of at which at least one falls within the abstract object definition,

requiring the user to choose one of the multiple objects,

validating the user choice against the abstract object definition.

12. A method as claimed in claim 11 wherein the multiple objects are graphic objects displayed on the computer screen, and the user chooses an object by focusing and clicking on the object.
