Dynamic multilayer security for internet mobile-related transactions

A method associated with one or more providers of authentication services for internet transactions in connection with use of a mobile device having an active generator that generates at transaction time dynamic authentication credentials calculated by the mobile device upon a different input data, and a transaction terminal that transmits at least part of the dynamic authentication credentials, the method comprising:

• electronically storing in one or more server memories data capable of linking the mobile device to one or more authentication services for internet transactions, the data including authentication parameters associated to server dynamic authentication rules of dynamic credentials and one or more identifiers related to a user and the one or more authentication services, the server dynamic authentication rules indicating for each related dynamic authentication credential whether success in its authentication is mandatory or optional to obtain a successful result of an authentication of a mobile-related internet transaction,
• sending to the mobile device personalization data for the mobile device to generate dynamic authentication credentials, the personalization data associated to the server stored authentication parameters associated to the dynamic authentication rules of dynamic authentication credentials, receiving from the transaction terminal a first dynamic authentication credential generated by the mobile device at the time of a first transaction using the personalization data and as input data a user's Personal Identification Number (PIN), one or more additional dynamic authentication credentials, each one calculated by the mobile device at the time of the first transaction upon the personalization data and a different input data, and at least one identifier related to the user and to the authentication service the dynamic authentication credentials refers to,
• authenticating the first dynamic authentication credential and, based on the server dynamic authentication rules and associated authentication parameters, further authenticating one or more of the one or more additional dynamic authentication credentials and generating an authentication result of the first mobile-related internet transaction by one or more processing devices having access to at least a portion of the data,
• wherein the authentication of each authenticated dynamic authentication credential is used to validate the corresponding input data.
