A method for determining harmful multimedia content by using multimedia content playback characteristics includes: determining a local harmfulness of each basic unit section of multimedia content to generate a local determination result; and generating global determination results to complement an error of the local determination result based on the multimedia content playback characteristics. The global determination results are generated by using a continuous determination value which has a meaning of harmful or harmless and is updated depending on each local determination result and the number of continuous determination results is counted or initialized depending on continuity of the local determination results.
