Introduction. The article deals with the actual problem of changing attitudes towards privacy in connection with the development of modern information and communication technologies. The purpose of the study is to philosophically analyze the phenomenon of post-privacy, identify the causes and consequences of its occurrence using logical, hermeneutic and comparative methods. The novelty of the work lies in the conceptualization of the socio-philosophical phenomenon of post-privacy. Theoretical analysis. It is stated that due to the development of computer technologies, we have lost control over access to our personal information, since any action we perform in the Internet space leaves digital traces. It is argued that the payment of an individual for participation in modern society is to provide access to his personal data for state and commercial organizations. It is noted that knowledge about a person gives power over him, enabling to influence his thinking and behavior and exercise social control over him. Conclusion. Since we live in an era of new information openness, we should reconsider our attitude to the problem of privacy. As one of the ways of social interaction in the era of post-privacy, the individual refuses to claim complete control over information about himself.
