| Abstract(in English) | Tardos proposed c-secure code based on randomness with certain distribution (Tardos’s code). The code is shorter than Boneh-Shaw code, but is still too long for practical use with large number of users. Isogai et al proposed shorter code than Tardos’s code. In this study, we focused on finding the colluders instead of code length. We improved the detection rate of pirate users for Tardos’s code. By performing simulation, we reached that the score distributions are proportional to code length of Tardos’s code. We also discuss the results compared with Isogai’s results. |
