Undetectability of an item of interest (IOI) from an attacker definition
Undetectability of an item of interest (IOI) from an attacker s perspective means that the attacker cannot sufficiently distinguish whether it exists or not. If we consider messages as IOIs, this means that messages are not sufficiently discernible from, e.g., random noise” [11]. The difference between unlinkability and undetectability is the following: in unlinkability, the IOI itself is not protected, but only its relationship to the subject or other IOIs is protected. For undetectability, the IOIs are protected as such [7]. Undetectability consists in, for instance, hiding the user’s activities or location [7]. Undetectability in the past was referred as unobservability. However, since unobservability comprises both anonymity and undetectability, LINDDUN method focuses on undetectability.
