Collapse Button Quick Abstract
CloudFoundry (CF) provides an open source platform-as-a-service software for deploying scalable software systems to the cloud. The architecture for CF is distributed by design and consists of several components which interact with one another through a message-oriented middleware. This message-oriented distributed design delivers on the scalability and resiliency requirements of the platform. In such a complex distributed multicomponent system, there is a steep learning curve for software developers to understand how components interact, what messages are exchanged between them, and how the message exchanges affect the behaviour of the system. In particular developers find it difficult to identify the execution flows, the authentication flows, interactions with the persistence layer, etc. We have developed a framework that allows interpreting the behaviour of the system by analyzing the exchanged messages between components, inspecting message contents, and extracting data and control flow across components. The paramount aim is to improve developers’ understandability of the system and to examine software resiliency through approaches like bug injection and message alterations. An initial version of our framework was released to the CF community and we have collected feedback that indeed show that we are achieving some of our goals.

Digital Object Identifier: 10.5220/0003139002000204

Proceedings of HEALTHINF 2011/BIOSTEC, ISBN: 978-989-8425-34-8

Collapse Button Quick Abstract
This paper describes an approach to solving scalability, distribution and accessibility problems associated with large collections of healthcare records. The technique described in the paper explains how to exploit Model-Driven Healthcare record implementations of the Health Level Seven (HL7) standards for Clinical Documents (CDA) and Continuity of Care Documents (CCD), such as those developed by the Model-Driven Healthcare Tools (MDHT) project to quickly and easily enable highly scalable, distributed healthcare applications. The MDHT project has developed models in the Unified Modeling Language (UML) of the HL7 standard that it uses to automatically generate high quality software implementations of the standard. The technique described in the paper shows how to retarget this code generation process to automatically create an alternative implementation using a technology called Connected Data Objects (CDO). This new implementation immediately supports scalable, distributed access to document collections. The paper then goes on to describe example applications made possible by the new capabilities provided by the alternative implementation.

EFFICIENT TRAITOR TRACING FOR CONTENT PROTECTION

Topic: Digital Rights Management

Author: Hongxia Jin

Affiliation: IBM Almaden Research Center, United States

Digital Object Identifier: 10.5220/0002235002700273

Proceedings of SECRYPT 2009/ICETE, ISBN: 978-989-674-005-4

Collapse Button Quick Abstract
In this paper we study the traitor tracing problem in the context of content protection. Traitor tracing is a forensic technology that attempts to detect the users who have involved in the pirate attacks when pirate evidences are recovered. There are different types of pirate attacks and each requires a different traitor tracing mechanism. We studied different types of attacks, surveyed various traitor tracing schemes and analyzed spectrum of traceabilities of different schemes using two representative schemes. We shall present some observations on the designs and their impact on the efficiency of the schemes. We shall also present various future directions that can lead to simpler and more efficient traitor tracing schemes for various pirate attacks.

Collapse Button Quick Abstract
The administrators and designers of modern Information Systems face the problem of maintaining their systems in the presence of frequently occurring changes in any counterpart of it. In other words, when a change occurs in any point of the system –e.g., source, schema, view, software construct– they should propagate the change in all the involved parts of the system. Hence, it is imperative that the whole process should be done correctly, i.e., the change should be propagated to all the appropriate points of the system, with a limited overhead imposed on both the system and the humans, who design and maintain it. In this paper, we are dealing with the problem of evolution in the context of databases. First, we present a coherent, graph-based framework for capturing the effect of potential changes in the database software of an Information System. Next, we describe a generic annotation policy for database evolution and we propose a feasible and powerful extension to the SQL language specifically tailored for the management of evolution. Finally, we demonstrate the efficiency and feasibility of our approach through a case study based on a real-world situation occurred in the Greek public sector.

TRAITOR TRACING FOR ANONYMOUS ATTACK IN CONTENT PROTECTION

Topic: Digital Rights Management

Author: Hongxia Jin

Affiliation: IBM Almaden Research Center, United States

Digital Object Identifier: 10.5220/0001929003310336

Proceedings of SECRYPT 2008/ICETE, ISBN: 978-989-8111-59-3

Collapse Button Quick Abstract
In this paper we take a closer look at traitor tracing in the context of content protection, especially for anonymous attack where the attackers pirate the content and re-distribute the decrypted plain content. When the pirated copies are recovered, traitor tracing is a forensic technology that can identify the original users (called traitors) who have participated in the pirate attack and involved in the construction of the pirated copy of the content. In current state-of-art, traitor tracing scheme assumes a maximum coalition size of traitors in the system and is defined to detect one traitor, assuming the detected traitor can be disconnected and tracing just repeats with the remaining traitors. In this position paper we argue this definition does not sufficiently reflect the reality where a traitor tracing technology is used to defend against piracy especially in the context of content protection. We believe a traitor tracing scheme should deduce the active coalition size and should be defined to detect all active traitors even taking into consideration that found traitors need to be technically disabled. We believe the traditional definition misleads in the design of an efficient and practical traitor tracing schemes while our definition much better fits the reality and can lead to design of efficient traitor tracing schemes for real world use.

A CLOSER LOOK AT BROADCAST ENCRYPTION AND TRAITOR TRACING FOR CONTENT PROTECTION

Topic: Digital Rights Management

Author: Hongxia Jin

Affiliation: IBM Almaden Research Center, United States

Digital Object Identifier: 10.5220/0002128502950298

Proceedings of SECRYPT 2007/ICETE, ISBN: 978-989-8111-12-8

Collapse Button Quick Abstract
In this paper we take a closer look at broadcast encryption and traitor tracing in the context of content protection. In current state-of-art, these are viewed as two separate and orthogonal problems. In this paper we challenge this separation. We presented example that shows it can be insecure if a broadcast encryption scheme offers no traceability. We also show it is insufficient to have a traitor tracing scheme that does not have revocation capability and does not support multi-time tracing. Furthermore we show supporting multi-time tracing may actually mean a traitor tracing scheme also needs to have broadcast capability. We hope the evidences we presented in this paper can raise the awareness of the connections between these two problems and shed new insights on future research directions in this important area.

Collapse Button Quick Abstract
As business information is made available via the intranet and Internet, there is a growing need to quickly analyze the resulting mountain of information to infer business insights. For instance, analyzing a company’s patent database against another’s to find the patents that are cross-licensable. IBM Research’s Business Insight Workbench (BIW) is a text mining and analytics tool that allows end-users to explore, understand, and analyze business information in order to come up with such insight. However, the first incarnation of BIW used a thick-client architecture with a database back-end. While very successful, the architecture caused limitations in the tool’s flexibility, scalability, and deployment. In this paper we discuss our initial experiences in converting BIW into a modern Service-Oriented Architecture. We also provide some insights into our design choices and also outline some lessons learned.

Proceedings of SECRYPT 2006/ICETE, ISBN: 978-972-8865-63-4

Collapse Button Quick Abstract
In this paper we study the traitor tracing problem, which originates in attempting to combat piracy of copy-righted materials. When a pirated copy of the material is observed, a traitor tracing scheme should allow to identify at least one of the real subscribers (traitors) who participate in the construction of a pirated copy. In this paper, we focus on the pay-per-view type of subscription-based scenarios, in which materials are divided into multiple segments and each segment has multiple variations. We present a systematic way to assign the variations for each segment and for each subscriber using an error-correcting code. We give sufficient conditions for a code to be able to trace at least a traitor when faced with a coalition of m traitors. We also prove that these sufficient conditions are also necessary when the code is an MDS code.

Collapse Button Quick Abstract
When building applications it is usually the case that developers are forced to focus on “one size fits all” solutions. Customization is often burdensome for the user, or so complex that it would be unrealistic to ask an end user to undertake this task. In the areas of personal information management and collaboration there is no reason to accept this limitation, as there is a body of information about the user that reflects their interests: namely their personal documents. The Dynamic Interest Profile (DIP) is a system intended to track user interests, allowing for the creation of more intelligent applications. In this paper we discuss our approach to implementing the DIP, challenges that this implementation presents, as well as the security and privacy concerns that the existence of such an application raises.
