Presenter Peter Mate Erdosi Abstract The eIDAS Regulation established the general acceptance of qualified signatures in the European Union and defines several Implementation Acts to support this goal. These rules are more general and there are numerous attributes of electronic signatures, which are not legislated, therefore several different electronic signatures can be created in legal way. The question arises whether these differences are meaningful or meaningless in case of qualified and non-qualified signatures, and how these differences can be measured. We use the Electronic Signature Dimension Model for the visualization of the distances between different electronic signatures and try to answer this question. This paper provides a comparative analysis between electronic signatures used by notaries in Romania and in Hungary through examination of relevant dimensions in connection with electronic signatures and defines a potential calculus for the determination of numeric distance between different but real signatures. All knowing technological and legal aspects of electronic signatures are evaluated, which can be derivable from other laws, the practice and literature. Finally, this paper tries to explain differences, in the other words, the meaning of distances between different electronic signatures and argues the measurement of conditions in accordance with cross-border acceptance of qualified electronic signatures in the European Union.
