The Grid environment is rapidly emerging as the dominant paradigm for wide-area-distributed application systems. The multimedia applications demand intense problem-solving capabilities, and Grid-computing makes it possible to share computing resources on an unprecedented scale among geographically distributed participants. In a Grid environment, virtual organisations are formulated and managed from a computing resource point of view. The Grid provider allows for the dynamic discovery of computing resources, the immediate allocation and provision of the resources, and the management and provision of secure access. Although the security problem in Grid environment is being addressed from the technological point of view, there is no work to identify the legal issues that are arising in Grid multimedia transactions.
