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.

主权项

1. A method of moderating activities on cloud-hosted service sites, the method comprising the steps of:
creating a database record for a first user when the first user registers at a first cloud-hosted service site, the database record including a plurality of profile fields and data in at least some of the profile fields; based on data in the profile fields of the first user's database record, assigning an initial risk score to the first user; identifying a cluster of database records associated with other users based on similarities in the profile fields thereof with respect to the profile fields of the first user, the record cluster having an associated composite risk score based on risk scores associated with the other users; assigning the composite risk score to the first user; and based on the first user's resultant risk score, taking an action with respect to a transaction conducted by the first user on the first cloud-hosted service site.
