: Exterior Security, Information Disclosure
It is difficult to ensure sender and recipient anonymity during message communication. The only
concern of traditional security approaches is to protect data content. This does not hide the
message path from the sender to the receiver and thus the anonymity is compromised.
The general problem is to ensure the anonymity.
How can the anonymity of an entity or a personal information be retained?
Mix the private information with other information so that the private information is not distinguishable
from other information. Create a set of equally probable information and hide the user information
by making it a part of the set. This set is called the anonymity set. If the size of the anonymity set
is large, it will ensure stronger privacy.
A mix-based system mixes input data of one user with data of other users to create the anonymity set
