摘要： Respective processes of decoding in error correction are subjected to parallel processing using a plurality of processing elements (PEs) each having the same configuration. At any given time, when processing of one process has been terminated, processing proceeds to a PE having the highest priority among PEs waiting for processing. The PE which has received data recognizes and executes the next process for that data.
摘要翻译：使用具有相同配置的多个处理元件（PE）对误差校正中的解码的各个处理进行并行处理。在任何给定的时间，当一个进程的处理已经终止时，处理进行到等待处理的PE中具有最高优先级的PE。已接收数据的PE识别并执行该数据的下一个进程。

摘要： An apparatus for embedding a digital watermark in a document image detects circumscribing outer shapes of characters in the document image and sets a plurality of reference lines that extend in the column direction and are spaced apart in the row direction by a basic pitch. The outer shapes include a first outer shape, a second outer shape that neighbors the first outer shape, and a third outer shape that neighbors the second outer shape, and the reference lines include a first reference line located between the first outer shape and the second outer shape, and a second reference line located between the second outer shape and the third outer shape. Control is performed for at least one of the second and third outer shapes so that a distance between the first reference line and an edge of the second outer shape is different from a distance between the second reference line and an edge of the third outer shape, in accordance with digital watermark information to be embedded.

摘要： The secret data is acquired externally by making an arithmetic operation between unique information of an apparatus and the first information managed secretly, and secretly held as key data in a key holding part. A MAC generation part generates the authentication data based on a hash value obtained from the data to be protected and the key data held in the key holding part 21. An image file generation part generates an image file to provide the unique information and the authentication data together with the data to be protected.
