Methods and apparatus enable dissimilar devices to exchange information over a computer network having a first device (14), a second device (16) and a verification server (12). The verification server (12) stores a database (10) of permissible sending and receiving devices. The first device (14) generates a request-send-authorization-signal in a first direction (1) to the verifying server. The verification server (12) receives and compares the request authorization signal to the database and in case of correspondence generates a send-authorization-signal in a second direction (2) to the first device. The first device, responsive to the send-authorization-signal, sends a communication signal in a third direction (3) to the second device. Before a complete exchange between the first device and the second device may occur, however, the second device (16) receives the communication signal and responsive thereto generates a request-receive-authorization-signal in a fourth direction (4) to the verifying server. The verification server receives the request-receive-authorization-signal, compares it to the database, and generates in case of correspondence a receive-authorization-signal in a fifth direction (5) to the second device, which receive-authorization-signal causes the second device to receive a message from the first device. A translation function is preferably provided prior to causing the second device to receive the message from the first device, which may be related to dissimilar device hardware, software device protocol, network security, domestic/international communication standards, language or other factors.
