- Published
- Record updated
Summary
SEO-DBSCAN is a secure outsourcing framework for the DBSCAN clustering algorithm, designed to protect sensitive input data when computation runs in the cloud. It combines a constant-round secure comparison protocol built on lightweight arithmetic secret sharing with a crypto-friendly DBSCAN variant. On synthetic datasets it reports up to $8.65\times$8.65× computational savings and $83.7\times$83.7× communication reduction against ppDBSCAN (AsiaCCS'21).
