Recently, Jung and Li  propose a highly efficient privacy-preserving product calculation scheme without requiring secure communication channels. Then, they present secure approaches to solve several application problems using the product calculation protocol. In this work, we observe several security flawsin their privacy-preserving product calculation scheme and some applicationprotocols. We show the security vulnerabilities will result in the disclosure ofprivate data. In two application protocols, almost all the private numbers will be revealed. We further suggest solutions to fix the security problems.
