Phi hiding assumption
WebSep 15, 2024 · Our contributions: The basic assumption is that the server has to abide by the “non-repudiation” requirement. Specifically, the server must not modify or fake or manipulate any block of the database in order to reveal privacy during or after the communication without intimating to the user.
