Methods and systems for determining whether an identity associated with a telephone call is fake

A method comprising:

• detecting, by a network traffic monitoring system associated with a network, an identity associated with a telephone call that enters the network from a first originating network;
• determining, by the network traffic monitoring system in accordance with a fake identity detection heuristic, that the detected identity associated with the telephone call is fake;
• identifying, by the network traffic monitoring system in response to the determining, an additional telephone call associated with the detected identity that enters the network from a second originating network that provides more transparent detail with respect to telephone calls than the first originating network;
• analyzing, by the network traffic monitoring system, one or more attributes associated with the additional telephone call as provided by the second originating network;
• and
• identifying, by the network traffic monitoring system based on the analyzing of the one or more attributes associated with the additional telephone call, an originating source of the telephone call.

A system comprising:

• at least one computing device that:
• detects an identity associated with a telephone call that enters a network;
• queries a first identity source list that includes entries representative of illegitimate identities and a second identity source list that includes entries representative of legitimate identities to determine whether the detected identity associated with the telephone call matches an entry included in the first identity source list or an entry included in the second identity source list;
• automatically determines, if the querying determines that the detected identity associated with the telephone call matches the entry included in the first identity source list, that the detected identity associated with the telephone call is fake;
• and
• analyzing, if the querying determines that the detected identity associated with the telephone call matches the entry included in the second identity source list, one or more attributes of the telephone call other than the detected identity to determine whether the detected identity associated with the telephone call is fake.
