Deceptive Information Retrieval

S Vithana, S Ulukus - Entropy, 2024 - mdpi.com
We introduce the problem of deceptive information retrieval (DIR), in which a user wishes to
download a required file out of multiple independent files stored in a system of databases …

Two-level private information retrieval

R Zhou, C Tian, H Sun, JS Plank - IEEE Journal on Selected …, 2022 - ieeexplore.ieee.org
