Abstract: Strong authentication tokens for generating dynamic security values having an acoustical input interface for acoustically receiving input data are disclosed. The tokens may also include an optical interface for receiving input data and may have a selection mechanism to select either the acoustical or the optical input interface to receive data. A communication interface may be provided to communicate with a removable security device such as a smart card and the token may be adapted to generate dynamic security values in cooperation with the removable security device. The acoustic signal received by the token may comprise a plurality of modulated carrier frequencies whereby each carrier frequency has been modulated with a data signal representing the full input data such that the input data are redundantly emitted over more than one modulated carrier frequency.

Abstract: Strong authentication tokens for generating dynamic security values having an acoustical input interface for acoustically receiving input data are disclosed. The tokens may also include an optical interface for receiving input data and may have a selection mechanism to select either the acoustical or the optical input interface to receive data. A communication interface may be provided to communicate with a removable security device such as a smart card and the token may be adapted to generate dynamic security values in cooperation with the removable security device. The acoustic signal received by the token may be modulated using a frequency shift keying modulation scheme using a plurality of coding frequencies to code the acoustical signal where each coding frequency may be an integer multiple of a common base frequency.

Abstract: The invention relates to modulation and demodulation circuits, such as envelope detectors used to demodulate amplitude-modulated (AM) signals. By coupling an analog circuit to a port of a digital component, a compact envelope detector can be obtained, which achieves demodulation of AM signals for direct coupling into a digital input port. Accordingly, a compact envelope detector may be used in the data receiving part of a sealed device requiring post-manufacturing data transfer, in combination with additional components that provide electromagnetic coupling, such as inductive, capacitive, or radiative. An example of such a device is a credit card sized authentication token.

Abstract: The present invention relates to the field of securing electronic transactions and more specifically to methods to indicate and verify the approval of the risk level of a transaction and to apparatuses for generating transaction risk level approval codes. In a method according to the invention transactions are classified into a limited number of categories. A user submitting a transaction to a server is requested to also generate and submit a dynamic transaction category approval code for the submitted transaction. On the server side a corresponding verification value is generated for the received transaction. In an alternative method according to the invention transactions are assigned one of a limited number of risk levels. A user submitting a transaction to a server is requested to also generate and submit a dynamic risk level approval code for the submitted transaction. On the server side a corresponding verification value is generated for the received transaction.
