Outsourced Similarity Search on Metric Data Assets
ABSTRACT
To set cloud computing setting in which similarity querying of metric data is outsourced to a service provider. The data is to be revealed only to trusted users. The goal of this research is to develop a transformation method for converting an original object p in a metric space into another metric space object. The data owner specifies a key value CK in order to define the instance to be used, then computes for each object p and uploads it to the server (i.e., service provider). At query time, the query user specifies his query object q and then submits the transformed query object to the server for similarity search.
