Cloud computing was defined as a model for empowering easy, on-demand community access into your shared pool of configurable computing resources that can be rapidly provisioned and published with minimal direction effort or service provider interaction. But there's a probability of widespread information loss or downtime due to internet connectivity issues or a localized component failure within a cloud computing environment. In order to reduce the service availability risk or loss of information, a multi cloud program where data is replicated to several clouds offered by different cloud suppliers are used. Once the assets are at the cloud, the clients eliminate control on them, as information in the cloud typically resides in a shared environment. With the development of a large number of cloud service providers, there is a requirement to safeguard confidential images saved in the cloud out of unauthorized users and also in the cloud service providers. This paper proposes an integrated encryption strategy based on DNA sequences and scrambling using zigzag pattern or Magic Square of doubly even order pattern to make sure double-fold security for the secure storage of private pictures on multi-cloud. 2. DEFINITIONS FOR THE PROPOSED SYSTEM 2.1. Cryptosystem : A cryptosystem is a five tuple (M, C, пЃ", пЃҐ, D) where i. M is a small collection of plain-text (images). ii. C is a small set of possible cipher-text. iii. ПЃ" is a finite set of possible keys. iv. For every K пѓЋ пЃ", there is an encryption principle, EK пѓЋ пЃҐ and a corresponding decryption guideline, DK пѓЋ D. Each EK : M п‚® C along with DK : C п‚® M are functions such that DK (EK (x)) = x, for each plain-text x пѓЋ M. 2.2. Synthesis: Creation of DNA sequences for the image data is referred to as Synthesis. DNA sequences comprise of four.
