Should we find a better way to store and secure our data? The answer is YES, Let’s see how? DNA molecules will store data. DNA molecules can store data more compactly than current data storing techniques. Developers have developed a complete system to encode, write and retrieve data from DNA molecules but the system is still in developing process, Researches from university of Washington and Microsoft are making lots of improvements in this system to secure data in efficient way. Optical device can store 10GB/mm^3. Recent research reported feasibility of optical discs capable of storing 1 PB data, yielding a density of about 100 GB/mm3. But still storing data in Zetta Bytes requires millions of units, its durability is also critical and requires maintenance to replace faulty units. DNA molecule can store digital data for long term and is extremely dense, estimated half life of DNA molecule is about 500 years. The write process (synthesis) for DNA storage maps digital data into DNA nucleotide sequences. Reading the data involves sequences the DNA nucleotide and decoding it back to retrieve original data. DNA storage technology is growing faster, in 1999 DNA-based storage was encoding and recovering a 23 character message while in 2013 developer successfully stored and retrieved 739kb data. Now the researches successfully saved and retrieved four images without losing a single bit of data. In conventional digital media storage device we encode information to strings of 0’s and 1’s. In DNA storing technology we convert 0’s and 1’s string to A’s, C’s, T’s and G’s strings which are chemically synthesized and dehydrated to store data for long term. A, C, T and G are types of DNA
