Abstract-At present, a company seeking to create competitive advantage, need to understand the data that is generated in the performance of their business. We intend to propose a framework that allows SMEs to take advantage of the information available, to adopt a set of measures supported by Business Intelligence (BI). The adoption of BI in Small and medium enterprises (SMEs) can create the need for organizations to adapt the processes that support systems for decision support, and may have to adapt their systems to the level of databases and applications, providing an additional perspective of information, enabling a more consistent analysis of the data in order to support the process of decision making.

Throughout the stunning development of wireless communication technologies, sensors and wireless sensor networks (WSN) are being used in almost every area, such as in healthcare field. The ubiquitous sensing enabled by WSN technologies, in particularly the wireless medical sensor network (WMSN), might be one important key success factor in the modern medical system. The recent advances, and wireless devices proliferation, had proved the technical feasibility of the pervasive health care systems. The data collected by sensors are very sensitive and important, and the leakage of them could compromise security and privacy. This work presents the pervasive health care systems (PHCS) focusing on security and privacy of pervasive environments.
