Abstract

A network including an optical sensing device and a registration server, wherein a secret key and a unique public identifier are installed in a non-volatile memory of the optical sensing device and in a database of the registration server, before the optical sensing device is connected to the network; wherein, the registration server is adapted to authenticate the optical sensing device when the optical sensing device is connected to the network by verifying the optical sensing device'"'"'s encryption, using the secret key, of a challenge message; wherein, if the authentication succeeds, the optical sensing device is registered in the database of the registration server.

Claims

1. A network including a sensing device for sensing coded data printed on a print media surface, a printer and a registration server, the network characterized by:

a secret key and a first unique public identifier which uniquely identifies the sensing device being installed in a non-volatile memory of the sensing device and in a database of the registration server, before the sensing device is connected to the network via the printer;

a second unique public identifier which uniquely identifies the printer being installed in the printer and in the database of the registration server;

the printer configured to obtain the first unique public identifier from the sensing device and communicate to the registration server the first and second unique public identifiers;

the registration server configured to determine from the received first and second unique public identifiers whether the sensing device should be registered with the printer and if so, to authenticate the sensing device by verifying an encryption from the sensing device, using the secret key, of a challenge message, the challenge message being generated, and transmitted to the sensing device, by the printer;

upon successful authentication, the sensing device being registered in the database of the registration server so as to be associated with the printer; and

,

the sensing device, when placed in an operative position relative to the print media surface, configured to sense at least some of the printed coded data and, using the sensed coded data, generate indicating data indicative of the identity of the print media surface.

2. The network according to claim 1, wherein the printer prints a first document in response to indicating data received from the sensing device.

3. The network according to claim 1, wherein the sensing device communicates with the printer via a wireless connection.

4. The network according to claim 3, wherein the sensing device connects to the printer when the sensing device comes within wireless communications range of the printer.

5. The network according to claim 1, wherein the sensing device is configured to transmit to the registration server via the printer, a registration request including the sensing device'"'"'s unique public identifier, the network further characterized by:

the printer configured to generate the challenge message in response to receipt of the registration request and to transmit the challenge message to the sensing device;

the sensing device configured to encrypt the challenge message using the secret key stored in the sensing device and to transmit the encrypted challenge message to the registration server via the printer; and

,

the registration server configured to decrypt the encrypted challenge message using the secret key stored at the registration server and to authenticate the sensing device by comparing the decrypted challenge message with the generated challenge message.

6. The network according to claim 5, wherein the registration server is configured to generate a session key, to encrypt the session key using the secret key, and to transmit the encrypted session key to the printer, the printer is configured to store the encrypted session key and to transmit the encrypted session key to the sensing device, and the sensing device is configured to decrypt the encrypted session key and to store the decrypted session key.

7. The network according to claim 6, wherein the printer stores, in non-volatile memory, at least one session key associated with the sensing device, the session key being retrievable via a unique public identifier of the sensing device.

8. The network according to claim 6, wherein the sensing device stores, in non-volatile memory, at least one session key associated with a printer, the session key being retrievable via a unique public identifier of the printer.
