Service level management of Web and Grid Services is an important issue that has to be solved in order to achieve large-scale deployment of services. The need to negotiate, measure and audit the quality of the services provided (in terms, for instance, of performance, cost or security) will increase directly with the proliferation of services. This paper presents our on-going efforts towards de...

A privacy auditing framework for Hippocratic databases accepts an administrator formulated audit expression and returns all suspicious user queries that satisfy the given constraints in that audit expression. Such an expression should be expressive, precise, unambiguous and flexible to describe various characteristics of a privacy violation such as target data (sensitive data subject to disclos...

We describe a practical auditing approach designed to encourage fairness in peer-to-peer streaming. Auditing is employed to ensure that correct nodes are able to receive streams even in the presence of nodes that do not upload enough data (opportunistic nodes), and scales well when compared to previous solutions that rely on tit-for-tat style of data exchange. Auditing involves two roles: local...

This paper shows the lack of standard procedures to audit e-voting systems and also describes a practical process of auditing an e-voting experience based on a Direct-recording Electronic system (D.R.E). This system has been tested in a real situation, in the city council of Coahuila, Mexico, in November 2008. During the auditing, several things were kept in mind, in particular those critical i...

A cycle in the parent relationship hierarchy of the UMLS is a configuration that effectively makes some concept(s) an ancestor of itself. Such a structural inconsistency can easily be found automatically. A previous strategy for disconnecting cycles is to break them with the deletion of one or more parent relationships-irrespective of the correctness of the deleted relationships. A methodology ...

We analyze in this paper the growth and welfare consequences arising from the lack of auditing commitment in a credit market with costly state verification. Specifically, two endogenous growth models, of which one allows lenders to commit to costly auditing strategies to identify borrowers’ investment returns and the other does not, are compared. We show that the inability to commit acts as an ...

A growing number of online service providers offer to store customers’ photos, email, file system backups, and other digital assets. Currently, customers cannot make informed decisions about the risk of losing data stored with any particular service provider, reducing their incentive to rely on these services. We argue that thirdparty auditing is important in creating an online serviceoriented ...

The cloud computing innovation appeared amid the21st century; outsourcing data to cloud benefit for capacity turns into a helpful yet proficient pattern, which benefits in saving endeavors on data support and administration. By the by, since the outsourced cloud stockpiling administration is not completely reliable, it raises security worries on the most proficient method to acknowledge data de...

This paper constructs and analyzes a simple model of auditing in which three principal issues are explored, namely: (i) The information contained in the report. An audit is a process of verification of a report of private information available to the reporter but not to the auditor. What information is contained in a report? Is it sufficient for the auditor to infer the private information exac...
