Abstract: Internet of things realizes connecting of Internet with anythings by sensing technology. Cloud computing provides requirement oriented application service for users by sharing resources of flexible integration and dynamic configuration. The basic concept and function architecture was definited for embedded urban computing based on abovcmenboned background. Taking application scenarios of embedded urban computing as the studying object, this paper comparcel data collecting and service provision between Internet of hhings technology and traditional mode, disscrtated sensing application deployment, data capturing, information spreading for human interacting with environment, elaborated user-oriented data management service, sensing application service, location query service provided by cloud computing,analyzed privacy protection and identity authentication for RFID, key management for wireless sensor network, privacy anonymized for participatory sensing, trusted access control for cloud computing around the security and privacy problem for embedded urban computing,proposed the future research direction.

Key words: Internet of things, Cloud service, Participatory sensing
