Abstract
In accordance with one embodiment of the invention, a method of integrating at least a portion of a watermark into at least a portion of a compressed image includes the following. The at least a portion of the watermark is encoded. THe at least a portion the image is compressed. The at least a portion of the-encoded watermark and the at least a portion of the compressed image are combined. Of course, many other embodiments in accordance with the invention are included within the scope of the present invention.
Claims27
A method of integrating at least a portion of a watermark into at least a portion of a compressed image comprising:
- encoding the at least a portion of the watermark;
- compressing at least a portion the image;
- and
- combining the at least a portion of the encoded watermark and the at least a portion of the compressed image.
A method of integrating a watermark into a compressed image comprising:
- dividing the watermark, or portion thereof, into groupings of bits;
- compressing the image, or portion thereof;
- and
- intermittently interspersing the watermark bit groups throughout the compressed image, or portion thereof.
A method of recovering a watermark from a combined image file of the watermark and a compressed image, said method comprising:
- determining locations in the combined image file that include groupings of bits for the watermark;
- extracting the bit groupings for the watermark from those pixel locations;
- and
- forming the watermark from the extracted bit groupings.
An article comprising:
- a storage medium having stored thereon instructions to integrate a watermark, or portion thereof, into a compressed image, or portion thereof, the instructions, when executed by a system, resulting in:
- dividing the watermark, or portion thereof, into groupings of bits;
- compressing the image, or portion thereof;
- and
- intermittently interspersing the watermark bit groups throughout the compressed image, or portion thereof.
An article comprising:
- a storage medium having stored thereon instructions to recovering a watermark, or portion thereof, from a combined image file of the watermark, or portion thereof, and a compressed image, or portion thereof, the instructions, when executed by a system, resulting in:
- determining locations in the combined image file that include groupings of bits for the watermark, or portion thereof;
- extracting the bit groupings for the watermark from those pixel locations;
- and
- forming the watermark, or portion thereof, from the extracted bit groupings.
