    摘要： A call tracking system and method that uses an automated filtering function to increase accuracy of call tracking. In some embodiments, the system utilizes a spam blocking module, such as a challenge-response test (e.g., a CAPTCHA), a blacklist for callers sharing certain criteria indicative of robo-dialed or spam calls, or other similar spam filter to block unwanted calls from being routed to an advertiser. By using a spam blocking module, the amount of noise in the call tracking system can be reduced and the attribution of calls correspondingly more accurate. In some embodiments, an interactive voice response (IVR) module is utilized to reduce the noise in the system by filtering or blocking unwanted calls. By utilizing an automated filtering function, the disclosed system improves the accuracy of call tracking and allows advertisers to better track the performance of advertising campaigns that they undertake.

    摘要： Authentication of a user initiating a communication may be achieved using a visual indicator of the user. Initiation of a communication may result in the initiator of the communication collecting image data associated with the initiator's identity. Additionally, the initiator may be required to perform a task, wherein a response to the task may be transmitted with the image data to the receiver of the communication. The receipt of the image data may allow a receiver of the communication to reduce spam and verify that the initiator is who it purports to be.

    摘要： A method of obtaining and automatically providing secure authentication information includes registering a client device over a data line, storing information and a changeable value for authentication in subsequent telephone-only transactions. In the subsequent transactions, a telephone call placed from the client device to an interactive voice response server is intercepted and modified to include dialing of a delay and at least a passcode, the passcode being based on the unique information and the changeable value, where the changeable value is updated for every call session. The interactive voice response server forwards the passcode and a client device identifier to an authentication function, which compares the received passcode to plural passcodes generated based on information and iterations of a value stored in correspondence with the client device identifier. Authentication is confirmed when a generated passcode matches the passcode from the client device.
