Multiple cloud and region data clean rooms

Abstract:

Embodiments of the present disclosure may provide a data clean room allowing secure data analysis across multiple accounts and across different regions and cloud providers. The data clean room may also restrict which data may be used in the analysis and may restrict the output. The overlap data may be anonymized to prevent sensitive information from being revealed. A version of a provider account can be created that is similar to a client account, such as in the same cloud type or the same region as the client database account. The client account can share data that is replicated to the provider account to complete client requests using an anonymized data and the cross reference table.
