Abstract: In one implementation, a method includes receiving a claim that identifies a first user profile page as allegedly impersonating a second user profile page on a social network, and retrieving first information associated with the first user profile page and second information associated with the second user profile page. The method can also include comparing the first information and the second information to identify indicators of impersonation. The method can further include, based upon the identified indicators of impersonation, determining that the first user profile page is likely impersonating the second user profile page on the social network, wherein first user profile page is determined to be likely impersonating the second user profile page when the first and second user profile pages are determined to be similar to each other; and returning a flag indicating that the first user profile page is likely impersonating the second user profile page.

Abstract: Embodiments of a computer system, a method, and a computer-program product (e.g., software) for use with the computer system are described. These embodiments may be used to evaluate a user request to regain control of an online account. For example, the user request may be submitted online using a web page, and may include information that establishes the user's identity or that substantiates that the user is the owner of the online account, such as a history of recent activities associated with the online account. This information may be evaluated by comparing it to stored information associated with the online account, such as a stored history of recent activities or one or more locations of a registered user when the registered user previously accessed the online account. After evaluating the user request, remedial action may be performed.
