eHealth Data Security in the Cloud

eHealth Data Security in the Cloud

Robust data security in the cloud enables the eHealth sector to offer privacy, efficiency, scalability, and flexibility.

Cloud technology is widely used in the medical field as the healthcare model is evolving and becoming more information-centric. Cloud enables communication, collaboration, and coordination across various healthcare providers for the purpose of providing rapid and at times, lifesaving services for patients. Cloud technology helps to store, manage, protect, share and archive electronic health records, medical images, laboratory information systems, and pharmacy information systems.

However, just like the cloud size, attack surfaces are also expanding. Attackers can target cloud platforms to gain unauthorized access to data, causing data loss, and breaches, for example. This forces the eHealth sector to have strong cloud data security in place.

Cloud data security can be achieved with various methods that allow healthcare providers to control and share sensitive data entirely or partially when data is at rest or in motion.


Applications for On-premise Data Security in eHealth


Double Key Encryption

Enables protection of sensitive data by securing encryption keys in the HSM and Azure cloud. Without access to both keys, the relevant data remains securely encrypted.


Multi-Cloud Key Management

A bring-your-own-key strategy (BYOK) allows to securely orchestrate services and data flows across multiple clouds and countries, including customers' local data centers.


Hardware Security Modules for General Purpose Use Cases

Enables key generation, storage, and exchange. Addresses various performance levels and physical security requirements while fulfilling compliance and regulatory mandates.



Select the key management solution by hosting encryption keys in the cloud provider’s platform or retaining the ownership control of customer-managed encryption keys.



Replacing sensitive data with non-sensitive tokens enables secure business operations without sharing sensitive information.


Securing blockchain-based applications

Specific generation of private and public keys used for blockchain transactions and secure storage of all related digital assets in a blockchain.


Key Generation and Derivation

In Germany, medical history as one of the most sensitive types of patient data which is subject to specific compliance requirements. Cryptographic keys protecting such data must be generated and protected by utilizing key generation and derivation.
