Patent ID: 8860963

Claim:
A communication system comprising: a communication apparatus configured to communicate with a destination apparatus; and an image processing apparatus configured to connect with the communication apparatus, wherein the communication apparatus comprises: a first memory configured to store first source identification information, wherein the first source identification information comprises a first character string comprising at least one character; and an additional-information notifying portion configured to notify the image processing apparatus of the first source identification information stored in the first memory, and wherein the image processing apparatus comprises: a second memory configured to store second source identification information, wherein the second source identification information comprises a second character string comprising at least one character; an information generator configured to generate third source identification information, wherein the third source identification information comprises the first source identification information notified by the additional-information notifying portion and the second source identification information stored in the second memory, and wherein the third source identification information comprises a third character string comprising at least one character; and a first transmitter configured to add the third source identification information generated by the information generator to image data and to transmit the image data comprising the third source identification information to the communication apparatus, wherein the communication apparatus further comprises: a second transmitter configured to transmit the image data transmitted from the first transmitter to the destination apparatus, and wherein the first source identification information and the second source identification information identify a source of the image data transmitted to the destination apparatus, and wherein the information generator is further configured to: determine whether a portion of the first character string is identical to a portion of the second character string; delete the identical portion from one of the first character string and the second character string when the portion of the first character string is identical to the portion of the second character string; and generate the third character string by combining an undeleted portion of the first character string with an undeleted portion of the second character string.
