Abstract

Recently, Liu et al. proposed a quantum private comparison (QPC) based on Bell entangled states (Liu et al. in Commun. Theor. Phys. 57(4): 583, 2012). This paper points out a security loophole in Liu et al.'s protocol, in which the third party can disclose the private information of both users. In addition, an improvement is proposed to avoid the loophole.
