摘要： A host computer which generates a print job subjected to printing by a printer stores a drawing command output from an application in a spool file via a graphic engine. A spool system, the graphic engine, and a job chasing function processing unit execute a chasing data generation process by using the drawing command. The spool system, the graphic engine, and a graphics control unit execute a print data generation process by using the same drawing command. At this time, the drawing command is read out and output so as to successively execute the chasing data generation process and print data generation process. With this configuration, there are provided a method of protecting leakage of information by which the contents of information can be reliably chased without requiring either a special application or a device having a special function and posing any restriction on the read or output path, and an information processing apparatus and driver program which implement the method.

摘要： The accuracy of reading a barcode embedded in a printed document is maintained, and at the same time, the amount of toner and the like consumed is reduced. When document information read by scanning is analyzed and the density of the document information is higher than a predetermined threshold vale, that is, when the printed document has a space enough to contain the barcode, the density of the barcode is set such that the density of the barcode is decreased as compared with a case where the density of the document information is lower than the predetermined threshold value. By changing the size of dots and the distance between the dots and thus decreasing the density of the barcode, it is possible to reduce the amount of toner and the like consumed. Then, the set barcode is synthesized with the document information, and the synthesized image is output.

摘要： A processor connected to an external bus in a conventional configuration made it possible to access its internal registers and local memory through the external bus and to read or update their contents. This created potential security threats including confidential data such as cryptographic keys being stolen and a newly developed piece of software being copied. In a conventional media processor connected to an external bus all access requests from a device connected on the external bus are honored. Security threats are reduced by providing a TLB in the bus interface unit of the media processor whose contents can be updated only from inside the media processor. The TLB checks whether the address specified by an external access request falls within the access-permitted areas registered in it. If it does, the access request from outside is passed on to the inside of the media processor; otherwise, it is rejected.
摘要翻译：以常规配置连接到外部总线的处理器使得可以通过外部总线访问其内部寄存器和本地存储器并读取或更新其内容。这产生了潜在的安全威胁，包括机密数据，例如加密密钥被盗，以及新开发的软件被复制。在连接到外部总线的常规媒体处理器中，来自连接在外部总线上的设备的所有访问请求都被保证。通过在媒体处理器的总线接口单元中提供TLB来减少安全威胁，其内容只能从媒体处理器内部更新。 TLB检查由外部访问请求指定的地址是否落在其中注册的访问允许区域内。如果是，则来自外部的访问请求被传递到媒体处理器的内部; 否则就被拒绝。
