Consumer-Centric Protection for Online Social Networks

Online Social Networks (OSNs) are a unique construct that is shaped by the advancement and availability of Internet technologies. A large portion of internet users make use of OSN services to share and celebrate their personal lives with friends and family. A substantial proportion of these shared experiences revolve around privacy-sensitive information. The OSN services handling privacy-sensitive information deploy state-of-the-art security and privacy preserving mechanisms. However, these protections are, to a great extent, not consumer-centric: this is the main focus of this study. In this paper, we define the notion of Consumer-Centric Protection (CCP) for OSNs. In this proposal, the individual user controls how her data can be accessed by her contacts (e.g. friends and family members) and others, thus giving control of user data back to the rightful owner — the user. This work is still in progress and in this paper we present our preliminary result

Using big data for customer centric marketing

This chapter deliberates on “big data” and provides a short overview of business intelligence and emerging analytics. It underlines the importance of data for customer-centricity in marketing. This contribution contends that businesses ought to engage in marketing automation tools and apply them to create relevant, targeted customer experiences. Today’s business increasingly rely on digital media and mobile technologies as on-demand, real-time marketing has become more personalised than ever. Therefore, companies and brands are striving to nurture fruitful and long lasting relationships with customers. In a nutshell, this chapter explains why companies should recognise the value of data analysis and mobile applications as tools that drive consumer insights and engagement. It suggests that a strategic approach to big data could drive consumer preferences and may also help to improve the organisational performance.peer-reviewe

Interest-Based Access Control for Content Centric Networks (extended version)

Content-Centric Networking (CCN) is an emerging network architecture designed to overcome limitations of the current IP-based Internet. One of the fundamental tenets of CCN is that data, or content, is a named and addressable entity in the network. Consumers request content by issuing interest messages with the desired content name. These interests are forwarded by routers to producers, and the resulting content object is returned and optionally cached at each router along the path. In-network caching makes it difficult to enforce access control policies on sensitive content outside of the producer since routers only use interest information for forwarding decisions. To that end, we propose an Interest-Based Access Control (IBAC) scheme that enables access control enforcement using only information contained in interest messages, i.e., by making sensitive content names unpredictable to unauthorized parties. Our IBAC scheme supports both hash- and encryption-based name obfuscation. We address the problem of interest replay attacks by formulating a mutual trust framework between producers and consumers that enables routers to perform authorization checks when satisfying interests from their cache. We assess the computational, storage, and bandwidth overhead of each IBAC variant. Our design is flexible and allows producers to arbitrarily specify and enforce any type of access control on content, without having to deal with the problems of content encryption and key distribution. This is the first comprehensive design for CCN access control using only information contained in interest messages.Comment: 11 pages, 2 figure

User-centric Privacy Engineering for the Internet of Things

User privacy concerns are widely regarded as a key obstacle to the success of modern smart cyber-physical systems. In this paper, we analyse, through an example, some of the requirements that future data collection architectures of these systems should implement to provide effective privacy protection for users. Then, we give an example of how these requirements can be implemented in a smart home scenario. Our example architecture allows the user to balance the privacy risks with the potential benefits and take a practical decision determining the extent of the sharing. Based on this example architecture, we identify a number of challenges that must be addressed by future data processing systems in order to achieve effective privacy management for smart cyber-physical systems.Comment: 12 Page

Identity principles in the digital age: a closer view

Identity and its management is now an integral part of web-based services and applications. It is also a live political issue that has captured the interest of organisations, businesses and society generally. As identity management systems assume functionally equivalent roles, their significance for privacy cannot be underestimated. The Centre for Democracy and Technology has recently released a draft version of what it regards as key privacy principles for identity management in the digital age. This paper will provide an overview of the key benchmarks identified by the CDT. The focus of this paper is to explore how best the Data Protection legislation can be said to provide a framework which best maintains a proper balance between 'identity' conscious technology and an individual's expectation of privacy to personal and sensitive data. The central argument will be that increased compliance with the key principles is not only appropriate for a distributed privacy environment but will go some way towards creating a space for various stakeholders to reach consensus applicable to existing and new information communication technologies. The conclusion is that securing compliance with the legislation will prove to be the biggest governance challenge. Standard setting and norms will go some way to ease the need for centralised regulatory oversight

Banking the unbanked using prepaid platforms and mobile telephones in the United States

The rapid growth of mobile phone usage and the continuous rise in wireless coverage fuel the expectations that access to financial services trough mobile phones could transform the way financial services are provided. The emergence of new and more efficient business models, can potentially resolve supply inefficiencies that explain the large unbanked population that exists in the USA, much larger than in most developed countries. Nearly 40 million US households (approximately 73 million people) are financially underserved (CFSI, 2007), of which 15 million households (approximately 28 million people) are totally unbanked. This problem is explained by the non adequacy of the value proposals offered by financial institutions to the demands of the US customers. The areas of poor alignment refer mostly to the design of products and the marketing and distribution networks used. To resolve these misalignments, this paper will argue that business models based on prepaid cards as products and mobile phones as transactional and distribution channels could be used in order to close the supply gap. We will call the business model proposed based on prepaid products and mobile phones mobile banking, since these two elements are the basis of the business model used companies such as Smart Money and G-Cash in the Phillipines, Wizzit in South Africa and M-Pesa in Kenya.prepaid platform; unbanked; financial services; mobile phones; prepaid cards;
