Today, Individuals have no faith in each other regarding their data, so they need to share their information in a protected and sealed stage. Cybersecurity spending has expanded dramatically in the past ten years without any indication of easing back. Around the world, associations intend to apportion more than $1 trillion somewhere between 2017 and 2021 to shield themselves from online dangers, per one industry report. Not with standing that stunning speculation, criminal programmers take advantage of both openly known and obscure weaknesses and block gadgets, applications, and organization interchanges. Other industry research shows that the number and cost of cyber-attacks have expanded. These sophisticated attacks frequently outsmart conventional security techniques, including verification, key administration, cryptography, and protection challenges. So, All the IT industry and its related work organizations looking for some more better options on this matter.In this regard Blockchain plays a very important role here, it helps in making that stage which ensures data security at an extended level. Viewed as one of the most problematic innovations across businesses, Blockchain unquestionably can possibly decrease costs, increment straightforwardness, upgrade security, and increment productivity, as compare to other data security techniques. In the previous work researchers explored so many ways of data security even with the blockchain also, but still, there is some gap in or scope of enhancements for the security of data, that gap we are going to bridge up in our proposed work.In this paper, we proposed blending Blockchain with cryptography and access key concept, which can be utilized as areas of strength for Cloud and Server-based organizations where data security is on higher priority. Blockchain offers an alternate way toward more prominent security, one that is more unfamiliar and not close as neighborly to cybercriminals. This approach diminishes weaknesses, gives solid encryption, and all the more checks information proprietorship and honesty. It could dispose of the requirement for certain passwords, which are habitually portrayed as the most fragile connection in network protection. A scattered public key foundation model lessens many dangers related to midway putting away information by taking out the clearest targets. Due to our proposed blending implementation of Blockchain, it becomes challenging for aggressors to take charge of hacking or exploiting data, split the difference, or mess with information; they can get success in any one of these only if a weakness exists at the stage level
