Wi-Fi fingerprint-based localization, a common indoor localization technique, plays an
important role in the Internet of Things, supporting a number of mobile applications, eg,
navigation indoor, trackingetc. However, Wi-Fi fingerprint-based localization suffers from the
privacy issue, disclosing users' location privacy and the data privacy of localization server
(LS). Existing work cannot completely protect LS's data privacy, and moreover, incurs larger
