Adaptive method for biometrically certified communication

A recipient communication device and method wherein a user authenticates a message that is being received. The method includes receiving, by a messaging utility of the recipient communication device, a message transmitted from a sender communication device. The messaging utility determines that one of (a) sender authentication of the message and (b) recipient authentication to open the message is required. In response to sender authentication being required, the recipient communication device transmits a request to the sender communication device for sender authentication of the message, and receives a certification of the message based on an authentication of a user input via the sender communication device. When recipient authentication is required, the recipient is prompted to enter biometric input at the recipient device. In one embodiment, a clearinghouse service authenticates a user of a communication device in order for the recipient communication device to receive certification of the user and/or the message.
