Securing Healthcare Data with Homomorphic Encryption

Organisations operating in today’s world of big data need to find better and more secure ways of hosting data on the cloud, as this is more important today than ever before, as almost every application presupposes efficient data flow as well as high storage spaces. Cloud computing has become an integral part of this solution, and storage space is effectively virtually unlimited. And on-demand access to data. However, alongside these advantages come concerns about the security and data security of its users, who store their data on cloud servers. Typically, users depend on the third-party cloud service providers to put in place efficient security measures, so that the stored data is not vulnerable to being penetrated by unauthorised personnel, exploitation or hacking of an organisation’s data. This reliance on the cloud creates a possibility of vulnerability, depending on the cloud providers, which can limit the user’s data. To address these challenges, recent vulnerabilities and threats to cloud computing services, as well as breakthroughs in cloud security research, have been ongoing. Pioneering cryptology that enables the everyday user keep ones data secure free from the impacts of cloud provider. Homomorphic Encryption (HE) is rather unique as it has been recently relatively new development that holds promise for future cryptographic solutions. This technique allows operations to be done on the original data in an encrypted format which means that any information considered sensitive does not, ever have to be decrypted even during processing. For this reason, data continues to be protected and maintains the lack of exposure during many of its stages, throughout its life-cycle computation.
