The increasing prevalence of cloud computing drives the exploration of various secure query schemes over encrypted data, among which secure spatial keyword query has drawn a great deal of attention ...

To address this issue, we propose an efficient privacy-preserving spatial-keyword range query processing in cloud in this paper. First, a keyword, location and range vectorization model is proposed.

These ESPs were further embedded as redline constraints in scenario-based land use simulations under four development pathways, forming a spatial structure that links ecological function with ...
