Secure data storage into DNA molecules compliant with biological constraints: Ensuring the confidentiality of data stored into DNA molecules

International audience► Context – Actual storage technologies (flash memory, hard drives,magnetic tapes,..) are outpaced by the exponential rise of digital dataproduction ► Advantages of DNA storage [2] – Density of 1021 bytes in one gram(106 times more compact than hard disks), durability for centuries,energy cost close to zero (molecules kept at room temperature with nomaintenance)► Motivation – Introducing security to ensure the confidentiality of thedata stored into DNA molecule
