  • DETECTING POTENTIAL FRAUDULENT ONLINE USER ACTIVITY
    Publication number: 20120072982
    Abstract: One or more techniques and/or systems are disclosed herein for identifying potentially fraudulent use of user generated content (UGC) for an online activity by a user. Server-based information and browser-based information associated with the user is identified and used to create a user signature. The user signature is associated with the UGC for the online activity in a cache-key. The cache-key is compared to a desired threshold for identifying potentially fraudulent use of the UGC for the online activity, where potential fraud may be detected if the cache key meets the desired threshold.
