Method and apparatus for recording / processing authentic image and / or sound data

The invention relates to a method and a device for recording/ processing of authentic image and/or audio data. To achieve an authentic image or sound recording the entire process of converting from analogue to digital signals, the identification or the characteristics of the individual components used are received, and recorded or stored after a signature calculation. The digital data are linked with each other in a device shown by the figure in such a manner that separation of the individual processes is not possible on the device without manipulations which can subsequently be recognised. The signature also enables the order and the complete nature of all visual or audio information to be logged in a tamper-proof manner.
