Windows Right Management Services protects RMS-enabled files or applications from unauthorized users. However, the offered security on the whole file prevents other trusted recipients with minor privileges to access it. The sender is obliged to send each time to these recipients another file that resembles to the former but does not contain sensitive information which is considered as time wasting especially when the number of recipients is increased. This paper designs and implements a new security layer that extends the WRMS security provided on a certain file, in a way that the file still keeps its security towards unintended or unauthorized recipients, but can be sent only once to trusted recipients having different privileges in such a way that each recipient will only see the data that grants access to.
