Abstract Previous bidirectional quantum private comparison (BQPC) protocols cannot meet the requirements in some special application scenarios, where only one party needs to obtain the comparison results without a third party (TP), such as scenarios for authority surveys or healthcare data sharing. In addition to this, the BQPC protocol has the potential of information leakage in multiple comparisons. Therefore, we design a new unidirectional quantum private comparison (UQPC) protocol based on quantum private query (QPQ) protocols with ideal database security and zero failure probability (IDS-ZF), for the reason that they have excellent unidirectionality and security. Concretely, we design a UQPC protocol based on Wei et al.'s work [IEEE Transactions on Computers67 2 (2017)] and it includes an authentication process to increase the resistance to outside attacks. Moreover, we generalize the protocol and propose a general model that can transform a QPQ protocol with or without the IDS-ZF property into a secure UQPC protocol. Finally, our study shows that protocols using our model are secure, practical, and have the IDS-ZF property.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
