-----BEGIN PGP SIGNED MESSAGE----- Some interesting hits for "data embedding" on IBM's patent server page... http://patent.womplex.ibm.com/details?patent_number=5671277 ISSUED: Sep. 23, 1997 FILED: Oct. 21, 1994 Snip of abstract: Additional data useful for the management of copies of a document for an image forming apparatus is embeddedin a hard copy of the document. The additional data is embedded in an inherent image of a document as pixels arranged in a prescribed format, and, preferably, the size of the pixels is such as to not be easily recognized with the naked eye. http://patent.womplex.ibm.com/details?patent_number=5659726 ISSUED: Aug. 19, 1997 FILED: Feb. 23, 1995 ABSTRACT: A method of embedding auxiliary information into a set of host data, such as a photograph, television signal, facsimile transmission, or identification card. All such host data contain intrinsic noise, allowing pixels in the host data which are nearly identical and which have values differing by less than the noise value to be manipulated and replaced with auxiliary data. As the embedding method does not change the elemental values of the host data, the auxiliary data do not noticeably affect the appearance or interpretation of the host data. By a substantially reverse process, the embedded auxiliary data can be retrieved easily by an authorized user. The patent office needs a fucking clue server. Hmmm... wonder if I can get a patent for one? - ------------------------ Name: amp E-mail: amp@pobox.com Date: 11/07/97 Time: 05:33:04 Visit me at http://www.pobox.com/~amp == -export-a-crypto-system-sig -RSA-3-lines-PERL #!/bin/perl -sp0777i<X+d*lMLa^*lN%0]dsXx++lMlN/dsM0<j]dsj $/=unpack('H*',$_);$_=`echo 16dio\U$k"SK$/SM$n\EsN0p[lN*1 lK[d2%Sa2/d0$^Ixp"|dc`;s/\W//g;$_=pack('H*',/((..)*)$/) == 'Drug Trafficking Offense' is the root passphrase to the Constitution.
