Background/Objectives. The aim of the study is to identify the prospects for the international legal protection of Big Data at the universal and regional levels and to make an analysis of the legal means of protecting Big Data while regulating relations in the global information society. Methods. A complex of general scientific and philosophical methods, including the logical, comparative-legal, formal-legal, systemic-structural, problematic-theoretical methods, as well as methods of analysis and synthesis, generalisation and description, were used in the research. Findings. The study revealed that the existing international treaties in the field of intellectual property protection do not take into account the peculiarities of the complex objects protection. Under the complex objects of intellectual property, Big Data is meant. There is an objective need to establish a legal regime of information and communication systems as complex objects at a universal level. This can be done by adding a separate act to the Berne Convention for the Protection of Literary and Artistic Works of 1886. Application/Improvements. The findings can be used in activities of international organisations to enhance their unification and harmonisation of the international information law.
