A mechanism for providing specification of a location of a user of a communication device. A method includes receiving, by a processing device a first position data of a communication device. The first position data is a location of the user of the communication device at a first time when the user begins to at least either compose a message on the communication device or initiate an application to compose the message. The method also includes receiving, by the processing device, a second position data of the communication device. The second position data is the location of the user at a second time when the user sends the message to a recipient via the communication device. The method also includes generating, by the processing device, a velocity vector based on the first position data, the second position data, the first time data and the second time data. The method further includes sending, by the processing device, the velocity vector with the message to the recipient.
