ABSTRACT:
A data processing apparatus includes an input section configured to receive data to be encoded, a first pseudo-random-number generating section configured to generate a first pseudo-random number, a second pseudo-random-number generating section configured to a second pseudo-random number, an address determining section configured to determine matrix address candidate values on the basis of a bit string of the second pseudo-random number generated by the second pseudo-random-number generating section, a matrix generating section configured to generate a matrix in which pixel values based on constituent bit values of the first pseudo-random number generated by the first pseudo-random-number generating section are set at matrix positions designated on the basis of the matrix address candidate values, and an encoding section configured to generate encoded data by executing exclusive OR operations between corresponding positional data in the matrix generated by the matrix generating section and the received data.
