A method for identifying JPEG 2000 images with different coding parameters, such as DWT-filters, code-block sizes, quantization step sizes, and resolution levels, is presented. The proposed method does not produce false-negative matches regardless of the different coding parameters. Moreover, the proposed method is fast because it uses the number of zero-bit-planes. This number can be extracted from the JPEG 2000 codestream by only parsing the header information. Experimental results showed the effectiveness of the proposed method for digital cinema applications.
