Information declassification aims for trusted release of secret information to public environment. Existing security specifications and enforcement mechanisms of declassification policies have focused on sequential programs. This paper generalized the specification of gradually delimited release policy for sequential programs to the security condition suited for multi-threaded programs. This security condition restricts that the interleaving of low transition events may not depend on secret information, confines the content of information declassified in accord with the content allowed to be released, and controls the location of declassification only through the special release statement. Moreover, we proposed monitoring mechanisms of policy enforcement and proved its soundness.
