What type of authorization maintains separate databases for each resource regarding user permissions?

1. Centralized Authorization

2. Decentralized Authorization

3. Role-Based Authorization

4. Attribute-Based Authorization

The correct answer is: Decentralized Authorization

The type of authorization that maintains separate databases for each resource regarding user permissions is decentralized authorization. This approach allows individual systems or resources to manage their own user permissions independently. Each resource can have its own database to define who has access and what levels of access are granted, leading to a more granular control model. In a decentralized model, the administration of access can be tailored to the specific needs of each resource without relying on a central authority. In contrast, centralized authorization relies on a single system or database to manage permissions for all resources, which can streamline management but may lack flexibility for individual resources. Role-based authorization categorizes users based on roles, which simplifies permission management but does not inherently involve separate databases for each resource. Attribute-based authorization involves granting permissions based on user attributes or characteristics rather than maintaining separate databases for each resource.
