A new method of error concealment for MPEG videos, in which motion vectors are hidden in
an MPEG bitstream as a watermark, is proposed in this paper. Several conventional …

A method of error concealment for JPEG2000 images is proposed in this paper. The
proposed method uses the layer structure that is a feature of the JPEG2000. The most …

We proposed a method for embedding binary data into JPEG bitstreams and extracting
embedded data from JPEG bitstreams using the standard JPEG decoder. In the proposed …

A method for embedding binary data into JPEG2000 bit streams was developed. Using the
method, a decoder can perfectly extract embedded data as well as it can when using the …

The state of the art in digital watermarking of visual data is briefly reviewed. A
communication perspective is adopted to identify the main issues in digital watermarking …

(57) ABSTRACT A multimedia coding and decoding system and method is presented that
uses the specific prediction mode to signal Supplemental information, eg, metadata, while …

This paper proposes random sign encryption in JPEG 2000-based data hiding. By
multiplying random signs to the discrete wavelet transformed coefficients of an image, the …
