Abstract
A method and a system for protecting data, a storage device, and a storage device controller are provided. In the present method, when a host accesses data in the storage device, whether the host performs a play operation or a copy operation on the data is first determined. If the host performs the play operation on the data, the storage device continues to execute the play operation so as to allow the host to access the data. On the other hand, if the host performs the copy operation on the data, the storage device executes an interference procedure so as to prevent or retard the data from being copied into the host.
