The application of current technical means plays an important role in case investigation, and the ensuing problem of protecting the basic rights of citizens has become more and more apparent. It is urgent to solve the constitutional rights protection of citizens’ communication secrets in the process of electronic investigation and evidence collection.The crux of the problem lies in the fact that although the application of new technology has a positive impact on the investigation of the case of the investigating organs, the investigation organs have failed to grasp the connotation of communication secrets accurately in the course of electronic data forensics, which makes it difficult for the investigating organs to achieve a difficult breakthrough in the balance between punishing crime and the guarantee of the secret constitutional rights of citizens’ communications. By exposing the reality of violating the secret of citizens’ communication in the process of electronic investigation and evidence collection, and under the guidance of the principle of proportionality, the case is typed according to the distinction between the levels of communication secrets, with a view to providing an effective solution to the problem of the protection of citizens’ communication secret rights in the electronic investigation and evidencegathering activities of the investigation organs.
