Abstract: Methods and systems for assigning reputation to communications entities include collecting communications data from distributed agents, aggregating the communications data, analyzing the communications data and identifying relationships between communications entities based upon the communications data.

Abstract: Methods and systems for operation upon one or more data processors for detecting image spam by detecting an image and analyzing the content of the image to determine whether the incoming communication comprises an unwanted communication.

Abstract: Systems and methods for reputation based connection determinations are provided. Systems used for reputation based connection throttling can include a communications interface, a reputation engine and a connection control engine. The communications interface can receive connection requests associated with an external entity prior to a connection being established to the external entity. The reputation engine can derive a reputation associated with the external entity. The connection control engine can allow or deny connection requests to a protected network based upon the derived reputation of the external entity.

Abstract: Methods and systems for collecting data from a plurality of voice over Internet protocol (VoIP) calls and determining at least one attribute for each of the plurality of calls. Relationships between the VoIP calls based on the determined attributes are identified, and a reputation score is assigned to a first entity based on the identified relationships. A call policy is associated with a caller reputation profile based on the reputation score.
