Abstract: Disclosed is a smart scheduler reflecting change of situation. The smart scheduler reflecting change of situation includes an interface unit and an alarm time decision unit. The interface unit both sends and receives contextual information to/from an external service-providing source. The alarm time decision unit reflects the contextual information that is received and updated from the external service-providing source, so that it may decide a final alarm time for performing a fixed schedule, even if any situation change occurs. The smart scheduler has the advantage that the determined schedule may be performed in the time in which a user designates, by differently setting up the alarm time according to the situation changes, whatever situation change brings about.

Abstract: The present invention relates to a method for detecting malicious code patterns in consideration of control and data flows. In the method of the present invention, a malicious code pattern is detected by determining whether values of tokens (variables or constants) included in two sentences to be examined will be identical to each other during execution of the sentences, and the determination on whether the values of the tokens will be identical to each other during the execution is made through classification into four cases: a case where both tokens in two sentences are constants, a case where one of tokens of two sentences is a constant and the other token is a variable, a case where both tokens of two sentences are variables and have the same name and range, and a case where both tokens of two sentences are variables but do not have the same name and range.
