This paper is presenting a conceptual mechanism for light-weight privacy-aware and secure data access control and filtering. This mechanism can be deployed at an edge node in order to assure that all data coming in and going out of it is properly protected and filtered. Goal is to keep private data locally and limit its exposure to outside entities (e.g., Cloud backend, external application or other edge nodes) while preserving the performance and security requirements for edge analytics. The data filtering at the edge node is done in a way that it is not possible for outside entities to identify end-devices and the data associated with them.
