A method is provided for a secure transfer of data or data files between participants, subscribers, and users. A first graphic image of the first original form is generated from the first original form of the data file or of the data by a first transformation process. A second electronic seal is generated from the first graphic image in a second step. In the following, the first original form of the data file or of the data and the second electronic seal of the graphic image are transmitted to a receiver. In a further step, the receiver generates a second graphic image of the original form, received at the receiver, with the same transformation process. The receiver generates a fourth electronic seal from the second graphic image, generated by the second transformation process. The transmitted second seal and the newly generated fourth seal are compared to each other with respect to identity in a last step.
