Abstract
A data processing apparatus is provided which controls the use of data in respect of a further operation. The data processing apparatus identifies whether data is trusted or untrusted by identifying whether or not the data was determined by a speculatively executed resolve-pending operation. A permission control unit is also provided to control how the data can be used in respect of a further operation according to a security policy while the speculatively executed operation is still resolve-pending.
