This paper addresses two emerging challenges that multimedia distributed systems have to deal with: the user's constant mobility and the information's sensitivity. The systems have to adapt, in real time, to the user's context and situation in order to provide him with relevant results without breaking the security and privacy policies. Distributed multimedia systems, such as the one proposed by the LINDO project, do not generally consider both issues. In this paper, we apply an access control layer on top of the LINDO architecture that takes into consideration the user's context and situation and recommends alternative resources to the user when he is facing an important situation. The proposed solution was implemented and tested in a video surveillance use case.

“…Each axis is independent and complex roles can be thus regarded as the aggregation of more basic roles. If attempts to integrate context sensitivity to RBAC ( [13]) and resource allocation patterns such as separation of duty ( [14]) exist, so do attempts to adapt RBAC to pervasive computing ( [15]). Moreover, several other models, such as Task-Based Access Control (TBAC) address the limits of RBAC.…”

Security requirements are part of business requirements, either because they derive from forensic rules, or because they derive from the business logic that should be translated into functional requirements to guaranty that a system meets its users' needs. Extending several notations such as the UML and the BPMN has been proposed as a means to bridge the gap between business processes engineering, security policies design and system engineering. However, a gap remains between these extensions on the one hand and between the large number of access control models on the other hand. Business logic, system engineering and security design thus remain separated when they should be intertwined. In this paper, we address this issue by defining a metamodel for access control to gather the different aspects of access control. We then introduce extensions to the UML et to BPMN that we derive from this metamodel and show that from a business-centric perspective, we can derive functional requirements, and model security to generate actual security policies.

A wearable device is an electronic device miniaturized to a wearable size with computing and wireless communication functions. In this study, we have applied a communication system using ultrasonic waves to a wearable device. Ultrasonic waves are safe for the human body and do not cause the malfunction of electronic equipment. In addition, communication using ultrasonic waves is effective for preventing ''skimming'' because ultrasonic waves can transmit through the human body and have a large attenuation in air. Wearable devices can also be used in areas where electromagnetic waves are limited. We have developed an experimental prototype device. The prototype contains a one-chip microcomputer used to verify the size and battery consumption of the wearable device. As a result, the developed prototype realized bidirectional communication with a suitable device size and power consumption. The communication speed corresponds to 250 kbps. This value is equivalent to that of a conventional IC card system using electromagnetic waves. With this proposed system, we can achive various practical applications that can maintain absolute privacy while transmitting information through the human body.
