“…Busom et al [14] recommend a multi-tiered system of reputation -the system is nominally half-duplex (voters and votees are distinct sets), but a caveat is added to this. Voters may endorse other voters' feedbacks as useful, and upon enough of these endorsements, a voter may gain additional status.…”

Trust and user-generated feedback have become increasingly vital to the normal functioning of the modern internet. However, deployed systems that currently incorporate such feedback do not guarantee users much in the way of privacy, despite a wide swath of research on how to do so spanning over 15 years. Meanwhile, research on systems that maintain user privacy while helping them to track and update each others’ reputations has failed to standardize terminology, or converge on what privacy guarantees should be important. Too often, this leads to misunderstandings of the tradeoffs underpinning design decisions. Further, key insights made in some approaches to designing such systems have not circulated to other approaches, leaving open significant opportunity for new research directions. This SoK investigates 42 systems describing privacy-preserving reputation systems from 2003–2019 in order to organize previous work and suggest directions for future work. Our three key contributions are the systematization of this body of research, the detailing of the tradeoffs implied by overarching design choices, and the identification of underresearched areas that provide promising opportunities for future work.

Privacy and security are the most important issues to the popularity of cloud computing service. In recent years, there are many research schemes of cloud computing privacy protection based on access control, attribute-based encryption (ABE), trust and reputation, but they are scattered and lack unified logic. In this paper, we systematically review and analyze relevant research achievements. First, we discuss the architecture, concepts and several shortcomings of cloud computing, and propose a framework of privacy protection; second, we discuss and analyze basic ABE, KP-ABE (key policy attribute-based encryption), CP-ABE (ciphertext policy attribute-based encryption), access structure, revocation mechanism, multiauthority, fine-grained, trace mechanism, proxy re-encryption(PRE), hierarchical encryption, searchable encryption(SE), trust, reputation, extension of tradition access control and hierarchical key; third, we propose the research challenge and future direction of the privacy protection in the cloud computing; finally, we point out corresponding privacy protection laws to make up for the technical deficiencies. INDEX TERMS Cloud computing, privacy, access control, attribute-based encryption, trust.

“…Similar considerations apply to the scheme in [10] which mainly focuses on the universal composability of reputation systems. An anonymous reputation system which gives users rewards for submitting useful comments is presented in [15]. Users can publish their assessment opinions which can then be endorsed by other users such that the original rater receives some reward upon receiving a threshold number of endorsements.…”

“…Various privacy-preserving reputation schemes [5,6,[9][10][11]15,[20][21][22] (see also Section 7 for more discussion) have been proposed to protect anonymity of raters and ratees to some extent, but none of these aims to hide reputation scores against the reputation manager. As far as we know, only [27,30,36] discuss the protection of reputation scores.…”

We introduce pRate, a novel reputation management scheme with strong security and privacy guarantees for the users and their reputation scores. The reputation scores are computed based on the (aggregated) number(s) of stars that users receive from their raters. pRate allows users to advertise privacy-friendly statements about their reputation when searching for potential transaction partners. Ratings can only be submitted by partners who have been initially authorised by the ratee and issued a rating token. The scheme is managed by a possibly untrusted reputation manager who can register users and assist ratees in updating their reputation scores, yet without learning these scores. In addition to ensuring the secrecy of the ratings, a distinctive feature of pRate over prior proposals, is that it hides the identities of raters and ratees from each other during the transaction and rating stages. The scheme is built from a number of efficient cryptographic primitives; its security is formally modeled and proven to hold under widely used assumptions on bilinear groups.
