Patent ID: 8184311

Claim:
An image processing system including an image processing device and a control device which controls data transfer to said image processing device, said control device comprising: a first connection unit configured to connect a network, and a second connection unit configured to connect a cable designed for data transfer, wherein the cable is different from the network, said image processing device comprising at least one of a first connection device configured to connect the network and a second connection device configured to connect the cable, said control device further comprising: reception means for receiving encrypted data from an external device via the network, decryption means for decrypting the received/encrypted data, and encryption means for encrypting the decrypted received data decrypted by said decryption means to generate re-encrypted received data, first determination means for determining whether or not a first communication channel is selected, wherein the first communication channel uses the network and the encryption executed by said encryption means to communicate with said image processing device, first transfer means for, when said first determination means determines that the first communication channel is selected, transferring the re-encrypted received data generated by said encryption means to said image processing device via the network, second determination means for determining whether or not a second communication channel is selected, wherein the second communication channel uses the cable to communicate with said image processing device, and second transfer means for, when said second determination means determines that the second communication channel is selected, transferring the decrypted data decrypted by said decryption means to said image processing device via the cable, wherein when said first determination means determines that the first communication channel is not selected, and said second determination means determines that the second communication channel is not selected, both of the transfer of the re-encrypted received data by said first transfer means to said image processing device and the transfer of the decrypted data by said second transfer means to said image processing device are restricted.
