An agent-based architecture for managing the provision of community care - the INCA (Intelligent Community Alarm) experience

Community Care is an area that requires extensive cooperation between independent agencies, each of which needs to meet its own objectives and targets. None are engaged solely in the delivery of community care, and need to integrate the service with their other responsibilities in a coherent and efficient manner. Agent technology provides the means by which effective cooperation can take place without compromising the essential security of both the client and the agencies involved as the appropriate set of responses can be generated through negotiation between the parties without the need for access to the main information repositories that would be necessary with conventional collaboration models. The autonomous nature of agents also means that a variety of agents can cooperate together with various local capabilities, so long as they conform to the relevant messaging requirements. This allows a variety of agents, with capabilities tailored to the carers to which they are attached to be developed so that cost-effective solutions can be provided. </p

Remarks on the Cryptographic Primitive of Attribute-based Encryption

Attribute-based encryption (ABE) which allows users to encrypt and decrypt messages based on user attributes is a type of one-to-many encryption. Unlike the conventional one-to-one encryption which has no intention to exclude any partners of the intended receiver from obtaining the plaintext, an ABE system tries to exclude some unintended recipients from obtaining the plaintext whether they are partners of some intended recipients. We remark that this requirement for ABE is very hard to meet. An ABE system cannot truly exclude some unintended recipients from decryption because some users can exchange their decryption keys in order to maximize their own interests. The flaw discounts the importance of the cryptographic primitive.Comment: 9 pages, 4 figure

Plan's CCCD approach - Country study PLAN-Kenya

The field study for Kenya, a part of the strategic formative evaluation on CCCD, was carried out August 16-23, 2009. This country study aimed at studying CCCD as an approach for development and how it was applied by Plan Kenya. The executive summary covers the main findings and recommendations of the field study in Kenya. Detailed findings and recommendations concerning Plan Kenya are described in this report. Findings and recommendations when relevant are incorporated in the synthesis report: Strategic Evaluation Study on CCCD for Plan NLNO. After the introduction the report starts with an overview on the country context and Plan Kenya. The third chapter presents how Plan staff and partners view CCCD, fourth chapter is on how CCCD works in practice, chapter 5 looks in more detail on partnerships. The report ends with a summary of the findings and recommendations. CCCD was introduced in Kenya in 2004. Programmes undertaken by Plan Kenya do take child centredness and community development as their main point of departure
