Abstract: The present disclosure relates to an image processing apparatus and an image processing method which enable reproduction of content data to be more reliably controlled. For example, with respect to a segment with which reproduction control for stream data obtained by encoding image data is carried out, a verification code of the stream data of the segment is produced, and the verification code produced is added to the stream data of the segment. In addition, for example, with respect to a segment with which reproduction control for stream data obtained by encoding image data is carried out, a verification code of the stream data of the segment is produced, the verification code produced and a verification code added to the stream data of the segment are compared with each other, and the reproduction of the stream data of the segment, a following segment, or both of them is controlled in response to agreement or disagreement between the verification codes. The present disclosure, for example, can be applied to an image producing apparatus, an image encoding apparatus, an image decoding apparatus or the like.
