Abstract:
1. An image processor, comprising: an image reading unit that reads source documents and converts read data into image data, an extracting unit that extracts password information and attribute information from the image data of each of the source documents read by the image reading unit, a password inputting unit that inputs the password information, a password determining unit that determines whether or not the password information inputted by the password inputting unit matches the password information extracted by the extracting unit, a source document determining unit that determines whether or not a source document read by the image reading unit is a first page, an attribute determining unit that determines whether or not the attribute information extracted from the first page and an attribute information extracted from the read source document match, under the condition that the source document determining unit determines that the source document read by the image reading unit is not the first page, a permitting unit that: directs the password determining unit to determine whether or not the password information inputted by the password inputting unit matches the password information extracted by the extracting unit, under the condition that the source document determining unit determines that the read source document is the first page, then if the password determining unit has determined that there is a match between the inputted password information and the extracted password information, permits the read source document to be printed, directs the attribute determining unit to determine whether or not the attribute information extracted from the first page and the attribute information extracted from the read source document match, under the condition that the source document determining unit determines that the read source document is not the first page, and then if the attribute determining unit has determined that there is a match between the attribute information extracted from the first page and the attribute information extracted from the read source document, permits the read source document to be printed, wherein the attribute information extracted from the image data of each of the source documents indicates a particular document group that each document belongs, and each document of a common document group has the identical attribute information.
