| Abstract [eng] |
The importance and volume of information stored in electronic form grows in days rather than years. More and more documents and public services are gradually being moved to electronic space. Some time before, document and data originality were endorsed by the original documents which were stored in archives. To ensure electronic documents originality the electronic signature technology was created. Electronic signature is an effective way to ensure the authenticity of the document, i.e. this is a reliable and raising confidence technology. What should we do in case of a need to increase confidence in the data, which are derived from the document and saved as a third party system data? One kind of the data have tendency to change, for example woman's surname after marriage. The other kind has opposite feature – it remains unchanged throughout the period of its existence, for example results of experiments, the accounting data. In the first case is often useful to know who, when and how changed the data. The second case is a bit different – it is crucial to make sure that the data did not change at all. This work is a research on the latter issue, i.e. how to increase confidence in the data, which must remain authentic. A system was developed during the research. It uses electronic signature to prove data authenticity rather than document. We also conducted an experiment comparing the existing and the proposed system performance. |
