Pressure profile data coding system and method

A pressure profile data coding method, comprising the steps of:

• mapping binary data standard format (0, 1) to a geometrical shape having prominent and non-prominent regions milled inside a code stamp and obtaining a pressure profile coded image of the code stamp;
• using the binary data standard format mapping of the code stamp as an exemplar for authentication of an object or process;
• using a pressure sensor array to obtain the code stamp's pressure profile coded image;
• acquiring a gray level image region having high gray color values mapping the prominent regions of the code stamp;
• acquiring a gray level image region having low gray color values mapping the non-prominent regions of the code stamp, wherein the high and low gray color regions are arranged in a square grid based on square shaped prominent regions milled inside the code stamp;
• extracting from patterns present in both horizontal and vertical components of the image;
• performing image position alignment using large areas of prominence disposed on the code stamp;
• obtaining finder patterns derived from a ratio between black blocks and white blocks of the image, wherein the pressure profile code is localized;
• obtaining a height and width of each finder pattern wherein an alignment pattern of the large areas of prominence used for image position alignment is localized;
• wherein the binary data standard format (0, 1) mapping occurs according to a located pressure profile code;
• and
• forming data squares on the code stamp so that the data squares are larger than a spatial resolution of the pressure sensor array.
