US 6,661,904 B1 · Method and system for automated electronic conveyance of hidden data

Abstract

A transformation of a data object called a personal logo contains personal data for transmitting from a client computer to a server computer. The personal data is embedded into transformation coefficients derived using one of several encoding techniques. The personal data is extracted from the transformation coefficients by the server computer to complete the transaction. The personal logo is created by or selected by a user and is made unique using a randomization algorithm to ensure differentiation from every other personal logo. Personal data is embedded into the unique personal logo in a way that hides it and makes it difficult for an unauthorized party to extract. The personal data includes data use limitations that limit what an authorized receiver may do with the personal data after receipt. Network transactions are automated through the creation of a drag-and-drop interface representing the act of data transmission. The particular personal data to be transmitted is requested by an application server and approved by the user. Keystroke errors are limited due to the automated nature of the transaction.

Dependent claims

A computer-readable medium containing instructions for controlling a computer system to encode data comprising:

establishing a first set of data;
establishing a first logo;
performing a fractal transformation on said first logo to create a first set of fractal transformation coefficients;
substituting at least one bit from said first set of data to a plurality of said first set of fractal transformation coefficients to form a second set of fractal transformation coefficients;
and
wherein said fractal transformation comprises selecting a plurality of library blocks from said first logo;
dividing said first logo into a set of target blocks;
comparing each target block to said plurality of library blocks to determine how well each said target block matches each of said library blocks;
selecting a library block and transformation coefficients corresponding to each target block;
replacing each said target block with said corresponding transformation coefficients and a reference to said corresponding library block;
and
writing each said corresponding transformation coefficients and said reference to said corresponding library block to memory.
