The development of a novel blockchain-based trust model for cloud computing is a pressing need. This model aims to provide a secure and reliable management of identities, which is a major challenge in cloud computing today. The model is designed to address the issues of identity management, access control, and data privacy in cloud-based applications. By leveraging the blockchain technology, the model ensures the integrity and authenticity of identities, thereby preventing identity theft and unauthorized access to sensitive data. The proposed model is expected to significantly enhance the security and reliability of cloud-based applications, making them more trustworthy and secure for users.
