Force detecting sensors (60-66, 60'-66') such as of the piezoelectric type are attached to a corresponding edge or side (80, 90) of each of a pair of mobile devices (50, 50'). In order to make the physical contact, the sensors (60-66, 60'-66') disposed along the edge (80, 90) of one of the pair of mobile devices (50, 50') are pressed against the sensors (60-66, 60'-66') disposed along the edge (80, 90) of the other one of the pair of mobile devices (50, 50') for applying force (81) to corresponding sensors (60-66, 60'-66') of the pair. Each of the mobile devices (50, 50') analyzes the output of its sensors (60-66, 60'-66') for identifying the distribution of the force (81) or force profile along its edge (80, 90). This information is then electromagnetically transmitted, for example, by wireless communication and picked up by the other device for performing a comparison between the distribution of the force (81) along the edge (80, 90) of one of the devices with the distribution of the force (81) along the edge (80, 90) of other one of the devices. When such comparison yields a match, the mobile devices (50, 50') are deemed to authenticate each other and data transfer between the two mobile devices is authorized. |
