Abstract
The present invention relates to the field of securing electronic transactions and more specifically to systems to indicate and verify the approval of the risk level of a transaction and to systems for generating transaction risk level approval codes.
Claims12
A system to secure electronic transactions configured to store criteria to classify transactions into a plurality of transaction categories;
- receive at least one transaction from at least one user;
- apply said criteria to a received transaction and assign said received transaction to one of said plurality of transaction categories;
- receiving from at least one user proof of said user's intention to do a transaction belonging to one of said transaction categories;
- and verifying whether said proof of said user's intention is valid for the transaction category of said received transaction.

A system to generate dynamic transaction category approval codes configured to obtain a transaction category indicator;
- capture the value of at least one dynamic variable;
- retrieve one or more secret values;
- apply an algorithm to generate a dynamic approval code using said transaction category indicator, said dynamic variable value and said one or more secret values;
- said algorithm determining with said retrieved one or more secret values a cryptographic secret key, cryptographically combining at least said dynamic variable value and said cryptographic secret key, and transforming the result of said cryptographic combination into a dynamic approval code.
