Detection and prevention of unwanted content on cloud-hosted services

摘要

The problem of abuse of privileges at cloud-hosted service sites is addressed by associating each user, preferably across multiple cloud-hosted service sites, with an individual “suspiciousness” score that may vary over time as additional user actions are detected and evaluated. Knowledge of the user is employed to better analyze the appropriateness or acceptability of user actions on the site.
