In recent years, security issues in web service environments have been widely studied and various security standards and models have been proposed. However, most of these standards and models focus on individual web services and do not consider the security issues in composite services. In this article, the authors propose an enhanced security model to control the information flow in service chains. It extends the basic web service security models by introducing the concepts of delegation and pass-on. Based on these concepts, new certificates, certificate chains, delegation and pass-on policies, and how they are used to control the information flow are discussed. The authors also introduce a case study from a healthcare information system to illustrate the protocols.

Cloud computing has been envisioned as the definite and concerning solution to the rising storage costs of IT Enterprises. There are many cloud computing initiatives from IT giants such as Google, Amazon, Microsoft, IBM. Integrity monitoring is essential in cloud storage for the same reasons that data integrity is critical for any data centre. Data integrity is defined as the accuracy and consistency of stored data, in absence of any alteration to the data between two updates of a file or record.  In order to ensure the integrity and availability of data in Cloud and enforce the quality of cloud storage service, efficient methods that enable on-demand data correctness verification on behalf of cloud users have to be designed. To overcome data integrity problem, many techniques are proposed under different systems and security models. This paper will focus on some of the integrity proving techniques in detail along with their advantages and disadvantages.
