CONTENT PROCESSING METHOD, CONTENT PROCESSING DEVICE AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a content processing method that can make pursuit of a content leaking source more efficient.SOLUTION: The content processing method reads out a content comprising a common part, plural first individual parts and an individualization candidate part from a recording medium (S11), achieves plural enciphered second individual parts each serving as an alternative of the individualization candidate part (S12), replaces the individualization candidate part out of the content by the achieved plural second individual parts (S13), and outputs a content for export generated by the replacement (S14). Each of the common part and the individualization candidate part can be decoded by each of plural producing devices, and each of the plural first and second individual parts can be decoded by only some reproducing devices corresponding to the parts out of the plural reproducing devices.SELECTED DRAWING: Figure 15B
