Abstract (en)
[origin: WO2006072568A1] A portable data support (1) is disclosed, with a non-volatile memory (11), a processor (15) and a watermark application (131) which may be executed by said processor (15), which is also stored on the data support (1). The watermark application (131) is embodied to check data (110, 140) stored on the data support (1) or provided for storage on the data support (1) for the presence of a digital watermark (152) or to mark said data (110, 140) with a digital watermark (151). The checking (152) or marking (151) is carried out on the data support (1) and the checked or marked data (110, 140), after the checking (152) or marking (151), is stored in the non-volatile memory (11) to remain for a subsequent undefined period.
