This document presents information on Rainbow Technology, which uses geometric shapes and colors to represent digital data and store it at high densities on paper. It can store up to 450GB on a single sheet. The document outlines the process of data encoding and decoding, where data is converted to values represented by colored shapes, and later decoded back to the original data. Key advantages are high density storage at low cost on biodegradable paper, but fading remains a challenge.

3. Introduction:-
 Rainbow Technology is a group of techniques to store digital data in some colors , color
combinations and some symbols known as rainbow format and therefore a rainbow
picture will be generated.
 Rainbow technology, a breakthrough in digital storage data enables us to store upto a
massive 450GB on just a piece of paper.
 With the help of rainbow system we would be watching full-length high-definition videos
from a piece of paper.

4. Process:-

5. Working:-
It uses geometric shapes such as squares and hexagons to represent data patterns,
instead of the usual binary method that uses ones and zeros to represent data.
 Besides, color is also used in the Rainbow system, to represent other data elements.
Files such as text, images, sounds and video clips are encoded in "rainbow format" as
colored circles, triangles, squares and so on, and printed as dense graphics on paper at
a density of 2.7GB per square inch.

7. Data encoding:-
Data to data conversion techniques takes place in four steps
A chunk of data bits are taken from data source(Normally binary file),which is known as a
word.
A word can be converted into a value that will be unique each different combination of bits
The value then passes through some error checking mechanisms . After producing some
error correction bits , it will attach to the data picture.
Thus the final output (data picture)will be generated.
 Here some absolute rainbow dots are printed along with the data to detect and correct errors.

8. Data Decoding:-
• Data picture is taken as input and the parameters like UPD,PBM,etc are read from
the header
• Value mapping function are used for mapping the arrangements done on actual data
• Some errors that occur due to color fading can also be handled at this stage.The
values are passed through some error correction mechanism.Automatic repairs are
also done here.
• Then the value to word conversion takes place.The encoded data picture is hence
decoded into the result data which will be the original data.

9. Principles:-
PRINCIPLE-1:
“Every different color or color combinations will produce different values.”
PRINCIPLE-2:
“Every color or color combinations can be converted in to some values and from the
values the colors or color combinations can be regenerated.”

10. Advantages:-
 Data can be stored on an ordinary paper.
 Larger amount of data can be had on lesser space.
 The extremely low-cost technology will drastically reduce the cost of storage and
provide for high speed storage too.
 Biodegradable nature of the storage devices would do away with the e-waste
pollution.

11. Disadvantages:-
 1.The paper has the tendency to fade away hence the data loss may occur.

12. conclusion:-
Once the Rainbow technology is in, soon we would be watching full-
length high-definition videos from a piece of paper!
With the popularity of the Rainbow Technology, computer or fashion
magazines in future need not carry CDs in a pack.
