Abstract: Embodiments of the present disclosure may provide a data clean room allowing secure data analysis across multiple accounts, without the use of third parties. Each account may be associated with a different company or party. The data clean room may provide security functions to safeguard sensitive information. For example, the data clean room may restrict access to data in other accounts. 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.

Abstract: Systems and methods for managing membership in a private data exchange are provided herein. In one embodiment, the method comprises adding a new member to a data exchange, wherein the data exchange comprises a set of listings, each listing comprising data from one or more datasets stored on a cloud computing service. An account type is assigned to the new member, the account type comprising at least one of a consumer type, provider type, or exchange administrator type. Each of the account types associated with one or more rights with respect to the set of listings, such that the new member has a set of rights based on the account type. The set of rights of the new member are then modified with respect to one or more listings from the set of listings based on a set of visibility and access rules for each of the set of listings.

Abstract: Systems, methods, and devices for generating a secure join of database data are disclosed. A method includes determining data stored in a first account to be compared with data stored in a second account. The method includes determining a function for generating a secure join key, wherein the secure join key includes a hashed string that hashes one or more of a data entry of the first account and a data entry of the second account. The method includes providing the secure join key to the first account and/or the second account.

Abstract: Sharing data in a data exchange across multiple cloud computing platforms is described. An example method can include copying, to a first cloud computing entity using a consumer account of the first cloud computing entity, a first subset of a data set associated with a provider account of a second cloud computing entity, wherein the provider account of the second cloud computing entity does not have access to the first cloud computing entity, and then copying, to a third cloud computing entity using a consumer account of the third cloud computing entity, a second subset of the data set, wherein the provider account of the third cloud computing entity does not have access to the first cloud computing entity, for which the first subset of the data set is different from the second subset of the data set.

Abstract: Techniques described herein can monitor various data metrics. The auto-insight techniques can further detect and rank data segments that contributed to, or counteracted, shifts in data and detect when such shifts occurred. Thus, the techniques described herein can detect and identify root causes in shifts in different metrics. The techniques include pruning and ranking causes to identify the root causes and identify non-relevant factors, as well.

Abstract: Sharing data in a data exchange across multiple cloud computing platforms and/or cloud computing platform regions is described. An example method can include generating a consumer account corresponding to a first cloud entity and receiving, by the first cloud entity, a copy of a data set from a provider account corresponding to a second cloud computing entity, wherein the first cloud computing entity and the second cloud computing entity represent different regions of a cloud computing platform. The method may also include accessing, by the consumer account, the copy of the data set.

Abstract: Systems and methods for managing membership in a private data exchange are provided herein. In one embodiment, the method includes generating a plurality of listings in a data exchange. A first listing of the plurality of listings may include a reference to a first version of shared data within a first database, where the first version is one of a plurality of versions of the shared data within the first database. The method further includes receiving a request from a member of the data exchange for access to the first listing and limiting, by a processing device, access for the member to the first version of the shared data of the first database referenced by the first listing.
