In a multicloud environment, an organization uses services from more than one public cloud provider simultaneously. This approach allows flexibility to operate with the best computing environment for each workload, whether private, public, or a combination of both. The adoption of multicloud strategies has become increasingly common due to the benefits of agility, flexibility, and reduced vendor lock-in. However, managing security complexities remains crucial to fully benefit from multicloud economics. It is evident from the literature survey that data in multicloud need privacy and security. In this connection, recent strategies have proposed to extend the users an authority to approve their data for storage, sharing and at the same time ensuring privacy, the paper presents the convergence of multicloud, blockchain and self-sovereign identity technique.
