“…Le et al [156] assumed that there were pre-defined rule regulations in the data processing scenarios. An inconsistency checking and removing algorithm was designed to ensure the enforceability for multi-access to stored data in cloud servers.…”

“…To protect sensitive data during the data transmission process, data encryption is usually utilized [153], [154]. For data protection on the cloud server, encryption scheme [149], [150], [151], a hierarchical data-accessing scheme [155], [156], [145], and other cyber technologies [21] were used. We believe that establishing an effective protocol in the platform is beneficial for both users and service providers.…”

Fast development of sharing services has become a crucial part of the cyber-enabled world construction process, as sharing services reinvent how people exchange and obtain goods or services. However, privacy leakage or disclosure remains as a key concern during the sharing service development process. While significant efforts have been undertaken to address various privacy issues in recent years, there is a surprising lack of review for privacy concerns in the cyber-enabled sharing world. To bridge the gap, in this study, we survey and evaluate existing and emerging privacy issues relating to sharing services from various perspectives. Differing from existing similar works on surveying sharing practices in various fields, our work comprehensively covers six branches of sharing services in the cyberenabled world, and selects solutions mostly from the recent five to six years. We conclude the issues and solutions from three perspectives, namely, from users', platforms' and service providers' perspectives. Hot topics and less discussed (cold) topics are identified, which provides hints to researchers for their future studies.

“…The enforceability issue can be illustrated as follows: If a party P is given access to R S but it and no other party has access to both R and S, it is not possible to actually compute R S. Alternately, some other party may be able to compute R S, but not get access to all the attributes that party P is given access to. We considered the issue of enforceability and potential changes to rules to ensure enforceability in [14]. In addition to direct changes to the rules, another way to enforce rules is by introducing trusted third parties (TP) that can obtain the necessary data and do the required manipulations.…”

“…In this paper we seek a single combined enforcement and query planning algorithm instead of the two different ones studied in [14] and [16]. For this, we consider the rules as queries also -which they are.…”

In this paper, we consider restricted data sharing between a set of parties that wish to provide some set of online services requiring such data sharing. Each party is assumed to store its data in private relational databases, and is given a set of mutually agreed set of authorization rules that specify access to attributes over individual relations or joins over relations owned by one or more parties. The access restrictions introduce significant additional complexity in rule enforcement and query planning as compared with a traditional distributed database environment. We examine the problem of minimum cost rule enforcement which simultaneously checks for the enforceability of each rule and generation of minimum cost plan of its execution. However, the paper is not focused on specific cost functions, but instead of efficient methods for enforcing rules in the face of access restrictions and inter-party data transfer needs. We propose an efficient heuristic algorithm for this minimal enforcement since the exact problem is NP-hard. In some cases, it is not possible to enforce the rules with the regular parties only. In such cases, we need help of trusted third parties (TPs). If all parties trust a single TP, such a party can enforce all unenforced rules, but it is desirable to use the TP minimally. We also consider the extended case where multiple TPs are required since not every regular party can trust a single TP.

“…On the other hand, consistency is the main issue when thinking of replicated data in distributed systems (Meixing, Sushil & Krishna 2014). Maintaining the temporal consistency of time-constraint data is an ultimate goal of most researchers who are working in DRTDBS due to the relaxation of consistency at the expense of predictability.…”
