“…The first proposals for implementing adaptive workflows were based on Multi‐Agent Systems (MASs) and ECA rules, temporal logics, and predictive behaviours . Similarly, the authors in Han et al dealt with managing exceptions in medical workflows. In the field of MASs, the paper in introduced a simulation‐based methodology to validate a design, manually generated by using a CASE tool while the one in exploits different design methods in a single logical framework.…”

We are assisting to a paradigmatic shift in developing Web applications since their components are often distributed and deployed as services among different organizations. Their logic is based on a set of actions that can be linked together by exploiting higher level languages more suitable to address the scale of the Web. On this multi-organization scale, applications can be influenced by different context events generated by the environment where they run. Handling these events requires run-time adaptations of the application's behaviour to react, properly and quickly, to changes. The paper addresses these needs by proposing a programming paradigm based on ''autonomic service compositions,'' ie, compositions that are able to self-change their structure, according to a specific life cycle, to allow for the continuation of execution, even if unexpected events arise. The approach exploits autonomic computing and reasoning for taking decision on information collected during processes execution. Autonomic actions on composition structures are performed using Event Condition Action rules and a set of meta-operations. The approach is detailed, analysed, and discussed with reference to some examples derived from a real-world application. KEYWORDSautonomic computing, self-management, service composition, software adaptation INTRODUCTIONWe are assisting to a significant change in Web applications development. Up to now, they have been often composed of a business logic hosted by a robust application server (in many cases replicated for ensuring fault-tolerance and scalability) exposing an HTTP interface for enabling remote access. Today, the diffusion of Web services is promoting a large-scale componentization of Web applications through services hosted by several containerized application servers that can belong to different administration domains.These multi-organization Web applications represent today an ideal IT solution for implementing virtual enterprises or complex valued added services, aiming at taking advantage of opportunities in a rapidly changing market, through B2B interactions with different organizations. In this context, the probability of experimenting with an exceptional behaviour is very high due to the high number of software components involved, which are not under the control of a unique organization. Moreover, business constraints introduce a new level of exception handling complexity derived by unsatisfactory behaviours of the services involved in Web processes.Programming the complex behaviour of a multi-organization Web application is a difficult conceptual activity. The heterogeneity of the execution environment calls for the adoption of a high-level language that is able to drive the behaviour of each component node of a large-scale application, which is based on distributed resources, human or automated, for performing the programmed tasks 1 whereas unexpected events introduce the need of adapting their control structure to satisfy the requirements emerging in the execution context. 2 Thes...

“…Although a number of projects and research works about access control models and languages have been presented in the last few years [8,10,11,15], only few proposals have attempted to provide a comprehensive framework specifically targeted to the healthcare scenario (e.g., [16]) and, in particular, to the management of exceptions (e.g., [3,14,17,18,19,20,21,22,23]).…”

Access control for smarter healthcare using policy spaces

A fundamental requirement for the healthcare industry is that the delivery of care comes first and nothing should interfere with it. As a consequence, the access control mechanisms used in healthcare to regulate and restrict the disclosure of data are often bypassed in case of emergencies. This phenomenon, called "break the glass", is a common pattern in healthcare organizations and, though quite useful and mandatory in emergency situations, from a security perspective, it represents a serious system weakness. Malicious users, in fact, can abuse the system by exploiting the break the glass principle to gain unauthorized privileges and accesses. In this paper, we propose an access control solution aimed at better regulating break the glass exceptions that occur in healthcare systems. Our solution is based on the definition of different policy spaces, a language, and a composition algebra to regulate access to patient data and to balance the rigorous nature of traditional access control systems with the "delivery of care comes first" principle.

“…The authors present a formal foundation for the support of dynamic structural changes of running workflow instances and criteria to identify and handling the possible exceptions resulting from a workflow change. Han et al [14] analyze the problem of managing medical workflow exceptions by giving an overview of past works in such a field and by proposing future research issues and solutions. The paper is focused on three main topics that would improve the quality of the medical procedures: representing, handling, and analyzing exceptions.…”

Abstract. One truth holds for the healthcare industry -nothing should interfere with the delivery of care. Given this fact, the access control mechanisms used in healthcare to regulate and restrict the disclosure of data are often bypassed. This "break the glass" phenomenon is an established pattern in healthcare organizations and, though quite useful and mandatory in emergency situations, it represents a serious system weakness.In this paper, we propose an access control solution aimed at a better management of exceptions that occur in healthcare. Our solution is based on the definition of different policy spaces regulating access to patient data and used to balance the rigorous nature of traditional access control systems with the prioritization of care delivery.
