Abstract

In order to warn a callee of a malicious telephone call from a caller using a caller ID blocking service, when evaluation information on a caller having stopped a phone call with one callee is received from the callee, the caller is identified from a call history and the identified caller is stored while being associated with the evaluation information. And then, when the identified caller calls the callee or another callee, the evaluation information corresponding to the identified caller is notified to the callee or the aforementioned another callee. Alternatively, the call history is provided at the request of the callee, thereby making the callee identify a caller who is a target of the evaluation information.
