In the present day context, users are making use of public storage services in the cloud and local storage devices such as CD's and DVD's. Fortunately, with the advancement in the techniques of compression and encryption it will become possible to store data equivalent to CD's or DVD's on a piece of paper in the near future. The applications are to well-established recording technologies, including magnetic tape and magnetic disk systems as well as CD/DVD/Blue-Ray optical data-storage systems. This technique is named as RAINBOW TECHNOLOGY. It is named as such since it mainly uses colors, color combinations and geometric shapes to store the data elements. The Rainbow technology is feasible because the output is in the form of printed text, which is readable by human eyes. By printing the encoded in a denser way, much higher capacities can be achieved. Paper is, of course, bio-degradable, unlike CDs or DVDs and sheets of paper also cost a fraction of the cost of a CD & DVD.
