In this paper, we investigate the Armknecht et al.'s papers and show some subtle faults in their works. In particular, our contribution is twofold. First, we show the privacy definition and the adversary goal presented by Armknecht et al. are completely different from the Paise-Vaudenay ones. Therefore, their different results arise from the fundamental differences in their definition of the privacy and their results cannot be valid in the Paise-Vaudenay model. Furthermore, we examine Armknecht et al.'s results and show that by using their methodology, different outcomes are achieved in the same theorems. In fact we prove by using their approach to the privacy that the highest achievable privacy level is narrow-weak privacy, which contradicts most of the theorems proved by Armknecht et al.
