USF-PAS: Study on core security technologies for ubiquitous security framework

Ubi-Com has emerged as an exciting new paradigm to provide intelligent computig and communications at anytime and anywhere. But, In order to take the advantages of such services, it is important that intelligent security framework be suitable for Ubi-Com. In this paper, we propose privacy and access control scheme by surveillance which is one of core security technologies for ubiquitous hybrid intelligent security framework. In this scheme, the device information and the signature information can be added to the image data obtained by the image capturing device to maintain security of the image data and use the image data as digital proof when a specific event is generated.
