Communication apparatus, transmission processing method, and reception processing method

A communication apparatus which is capable of performing communication via an IP network, comprising:

• a reception unit configured to receive image information transmitted via the IP network;
• an encryption unit configured to encrypt the received image information;
• a storage unit configured to store the received image information;
• a determining unit configured to determine whether or not the received image information was transmitted using IPsec;
• and
• a controller unit configured to be operable when said determining unit determines that the received image information was transmitted using IPsec, to cause the image information to be stored in said storage unit after being encrypted by said encryption unit, whereas when said determining unit determines that the received image information was transmitted without using IPsec, to cause the image information to be stored in said storage unit without being encrypted by said encryption unit.

A communication apparatus which is capable of performing communication with a receiving apparatus connected to the communication apparatus via an IP network, comprising:

• an encryption unit configured to encrypt image information to be transmitted to the receiving apparatus;
• a determining unit configured to determine whether or not the image information is to be encrypted by said encryption unit for transmission;
• an information-adding unit configured to be operable when said determining unit determines that the image information is to be encrypted by said encryption unit for transmission, to add additional information indicative of execution of encrypted transmission to the image information;
• and
• a transmission unit configured to transmit the image information having the additional information added thereto and encrypted by said encryption unit to the receiving apparatus.

A communication apparatus which is capable of performing communication with a transmitting apparatus connected to the communication apparatus via an IP network, comprising:

• a reception unit configured to receive image information transmitted from the transmitting apparatus;
• a decryption unit configured to decrypt the image information received by said reception unit when the image information was encrypted;
• a determining unit configured to determine whether or not the image information received by said reception unit was encrypted;
• an information-adding unit configured to be operable when it is determined by said determining unit that the image information was encrypted, to add additional information indicative of execution of encrypted transmission to the image information decrypted by said decryption unit;
• and
• a printing unit configured to print the image information having the additional information added thereto.
