The erosion of trust put in traditional database servers and in database service providers and the growing interest for different forms of selective data dissemination are different factors that lead to move the access-control from servers to clients. Different data encryption and key dissemination schemes have been proposed to serve this purpose. By compiling the access-control rules into the encryption process, all these methods suffer from a static way of sharing data. With the emergence of hardware security elements on client devices, more dynamic client-based access-control schemes can be devised.
