Image processing apparatus for detecting confidential drawing commands within print data

摘要

An image processing apparatus includes a memory, a generation unit, and a warning unit. The memory stores drawing commands used to determine print data for which security control is necessary. The generation unit generates raster image data in accordance with input print data. The warning unit issues a warning that security control is necessary for print data in a case where raster image data has not been successfully generated from the print data in the generation unit and drawing commands of the print data include a drawing command stored in the memory.

1. An image processing apparatus comprising:
a memory configured to store drawing commands indicating print data for which security control is necessary; and a hardware processor configured to implement: a generation unit configured to generate raster image data in accordance with input print data; a rasterization error detecting unit configured to detect a rasterization error before an image output process; a confidentiality detecting unit configured to detect a confidentiality of the input print data in response to the rasterization error detecting unit detecting the rasterization error by comparing the input print data and the drawing commands which are stored in the memory; and a warning unit configured to issue a warning that security control is necessary for the input print data in response to the confidentiality detecting unit detecting the confidentiality.
