1. A method for controlling an image forming apparatus, the method comprising: storing document data including original data having authentication data and copy-forgery-inhibited pattern data in a storage region, the original data and the copy-forgery-inhibited pattern data being vector data; comparing the right of a user who gives an instruction to transmit the document data to an information processing apparatus with the authentication data when transmitting the document data; and transmitting the original data as the vector data being separated from the copy-forgery-inhibited pattern data, as the vector data to the information processing apparatus in a case where the user has a right as a document owner as a result of the comparison, and to combine the copy-forgery-inhibited pattern data as the vector data and, the original data as the vector data, and transmit the combined data as data in an image data format to the information processing apparatus in a case where the user has a right as an authenticated document reader as the result of the comparison, the copy-forgery-inhibited pattern data in the data in the image data format being unable to be deleted at the information processing apparatus.
