The article discusses a general problem of ensuring data confidentiality in a cloud environment and highlights a specific problem of ensuring the confidentiality of spatial computing in this kind of environment, shows the reasons for this specialty and suggests a possible solution. The purpose of this research is to analyze the approaches for ensuring the confidentiality of spatial computing in the untrusted computing environment. The relevance of the study is determined by the increasingly widespread use of various wearable devices, such as smart glasses or mixed reality headsets, which can combine digital information from the computer system and from the external environment in the user’s field of view, allowing him to interact with the digital world while maintaining awareness of the physical world. To perceive, analyze and interpret spatial information coming from the physical environment, it is necessary to perform spatial computing, not only by a wearable device itself, but also in a cloud environment. The idea of the solution for ensuring the confidentiality of spatial computing in the untrusted computing environment is proposed by the author and is based on encryption of a spatial index constructed in the form of the R*-tree.
