It has become a convenient tool for people to find out information on the various products or services offered at the comfort of their homes. In order to ensure of getting the “best deals”, most people tend to turn to online rating systems for advices to make informed decisions regarding the purchase of products or services. However, it remains a mystery on how reliable or trustworthy are such rating systems. Often, these rating systems are susceptible to malicious attacks which mislead the consumers.
