Abstract
A method for securely transacting a transaction based on a transaction document having an image contained within the document, the method includes the steps of compressing an image on the document; scrambling the structure of the compressed image according to a permutation; obtaining the inverse permutation; applying the inverse permutation to the scrambled image for obtaining an unscrambled image; and decompressing the unscrambled image.

A method for securely permitting a transaction based on a transaction document having an image contained within the document, the method comprising the steps of:
- a) compressing an image;
- b) scrambling sequential ordering of the structure of the compressed image according to a permutation to obtain a scrambled compressed image;
- c) embedding the scrambled compressed image on the document
- d) obtaining the inverse permutation;
- e) applying the inverse permutation to the scrambled compressed image for obtaining an unscrambled compressed image;
- and
- f) decompressing the unscrambled compressed image.
A computer system for securely transacting a transaction based on a transaction document having an image contained within the document, the computer system comprising:
- a) a compressor for compressing an image on the document;
- b) a scrambler for scrambling sequential ordering of the structure of the compressed image according to a permutation to obtain a scrambled compressed image;
- c) a receiver for obtaining the inverse permutation;
- d) a descrambler for applying the inverse permutation to the scrambled compressed image for obtaining an unscrambled compressed image;
- and
- e) a decompressor for decompressing the unscrambled compressed image.
A method for securely permitting a transaction based on a transaction document having an image contained within the document, the method comprising the steps of:
- a) compressing an image;
- b) scrambling a structure of the compressed image according to a permutation that determines scrambling of sequential ordering of the structure of the compressed image so that content of the scrambled compressed image, when decompressed, is humanly incomprehensible without unscrambling with an inverse permutation;
- and
- c) embedding the scrambled compressed image on the document.
A method for securely permitting a transaction based on a transaction document having an image contained within the document, the method comprising the steps of:
- a) obtaining an inverse permutation;
- b) applying the inverse permutation to a scrambled compressed image that unscrambles sequential ordering of the structure of the compressed image so that content of the scrambled compressed image, when decompressed, is humanly comprehensible for obtaining an unscrambled image;
- and
- c) decompressing the unscrambled compressed image.
