Enclave versions

No new enclaves have been released.

Python SDK

• The Python SDK was updated to version 0.31.1.

v3.18.1 - 04/07/24

New features

• Addition of encrypted temporary storage: Python workers starting from version v24 will have access to a large (800 gigabytes) and very fast encrypted volume that can be used for storing temporary data that would otherwise not fit into memory. This volume is available to every user-defined Python script by writing your data to the directory /scratch. Data written to that location will always be encrypted and deleted after the script has been run.
• New data lab: We reworked the internal data lab implementation to make it both faster and compatible with much larger datasets (100G+).

Enclave versions

• New Python worker
  • Identifier: decentriq.python-ml-worker-32-64:v24
  • Hash: fb3f8ffc47d568f241e57800d895318eba71a1edc836b032bcc85cd30fccd17b

Python SDK

• The Python SDK was updated to version 0.30.0.

v3.18 - 27/06/24

New features

• Lookalike model quality: The lookalike audience creation dialog now includes numeric indicators and a visual representation of model quality. Brands can see how choosing a larger lookalike audience affects precision in real time. Publishers and Decentriq can view model performance summary reports to diagnose data issues.
• Conversion measurement: There is a new dedicated clean room creation workflow for conversion measurement that requires no coding to set up. It supports cross-publisher attribution and offers popular rules like last click, even credit, and U-shape. Clickthrough and viewthrough lookback windows are independently configurable.
• Exclusion targeting: Media clean rooms now support exclusion targeting. Brands can target all users meeting criteria except those on a blocklist.

Bugfixes

• Fixed an issue where editable fields may be small, and only show part of the text. This change is most notable while editing long clean room names in draft mode — you can now see much more of a long name while editing, especially on higher resolutions.
• Fixed an issue where long column names may overflow beyond the edge of the window.
• Fixed an issue where users may not see the deletion confirmation dialog when deleting test datasets in draft mode.
• Fixed an issue where some text, especially in sidebars, was not easily legible on very low or very high resolutions.

Enclave versions

• No enclave changes, please refer to v3.15 below.

Python SDK

• The Python SDK was updated to version 0.29.1.
• Direct data connectors: Data connectors can now be directly attached to a computation, allowing data to be sent directly to an external location such as a cloud provider or DSP without being locally stored by Decentriq or the computation result owner. The scripts should additionally now be easier to read and more concise.

v3.17 - 30/05/24

New features

• The Media DCR can now be configured to allow exporting of the audience by the advertiser.
• The Media DCR now shows overlap statistics even if the Insights collaboration type is not selected.
• We introduced an optional data partner role in the Media DCR. If added, such a user will provide the seed audience data on behalf of the advertiser.
• We introduced a data partner portal which allows organizations acting as data partners to configure their visibility to advertisers and data usage policies.
• It is now possible to import the schema for table nodes from a CSV file.
• The automated platform emails appear now in a fresh look.
• We changed the platform’s font from Montserrat to Inter for improved readability.
• Various small UI and wording improvements.
• Dataset uploader now has automatic character encoding detection, allowing now also UTF-16 (and other) encoded files.

Bugfixes

• Some logo files were not cropped correctly.
• Media DCR: The data tab UI didn’t update correctly when provisioning a new dataset.

Enclave versions

• No enclave changes, please refer to v3.15 below.

Python SDK

• The Python SDK was updated to version 0.28.0.
• Added support for adding participants with role data partner when creating Media DCRs.

v3.16 - 02/05/24

New features

• Publisher and Brand Markets: We have added the ability for publishers to declare which markets they are active in. Brands will now be able to browse publishers that are active in markets they choose during Media DCR creation. Brands should expect to see more publishers to choose from when creating clean rooms. Most publishers in our Decentriq-Ready program are now visible within the markets they operate in.
• Media DCR Controls: We have added a new setting to allow finer control over how data is used in our Media DCR UI. Brands can choose to explicitly exclude the seed audience from lookalike model predictions, and publishers may choose to not share audience segment sizes in the insights dashboard.
• Excel uploads: It is now possible to choose files with the xls or xlsx extension when uploading in the UI. This takes the first sheet of the excel file, and otherwise treats it the same way as a csv upload.

Bugfixes

• Small graphical improvements to make the UI more legible and consistent, especially on smaller screen resolutions.
• More detailed error messages for modeling issues in Lookalike activations and when trying to set inconsistent/impossible user permissions in the SDK.
• It is no longer possible to create tables with zero columns, which could cause issues with some types of downstream computations.
• Fixed a display bug where it was sometimes not possible to see the preview size of a pending Airlock node request.
• Added SDK support to improve coverage for features introduced to the Media DCR in the previous release.

Enclave versions

• No enclave changes, please refer to v3.15 below.

v3.15 - 27/03/24

New features

• Publisher Portal - The Publisher Portal now supports a publisher contact form. For publishers that have configured a contact email in the portal, brands viewing them in the publisher discovery interface will be presented with an option to contact them. We also added several UI improvements.
• Insights Dashboards - The Insights dashboard has been extended with Basic, Detailed and Comparison views. This new experience gives the most important insights first and makes it easier and faster for marketers to get the answers they need.
• UI - The Decentriq platform now has a new background color.
• Synthetic Data Report - If the synthetic data generation report includes an error, this is displayed more gracefully now.

Bugfixes

• Fixed a bug so that resizing of the window now also resizes the insight chart.
• Fixed a bug so that the organisation logos don’t overflow anymore on small screens with wide logos.
• Fixed a bug so that during the computation of the insights and lookalike audience no error screen is displayed.
• Fixed a bug that prevented a brand from inviting a publisher to a clean room under some organization configurations.

v3.14 - 11/03/24

New features

• Revamped Look & Feel: The UI now features a different sidebar layout and several other improvements, making it easier to navigate and improving legibility.
• Publisher Portal: Advertisers can now easily find and create Media Clean Rooms with suitable publishers. Publishers can choose to be discoverable by specifying their preferences and default settings. Advertisers can see these publishers and Media Clean Rooms already pre-configured by them. The process for publishers inviting advertisers to collaborate remains the same.
• Privacy Noise for Media Insights: We now add a small amount of noise to all results from the Insights tab in Media clean rooms. This follows principles established in differential privacy using the Laplace Mechanism. For a more detailed discussion, please see the tooltips and mouseover text in the dashboard iteself or request a copy of our whitepaper.
• SDK Improvements: We are also releasing v0.25 of our python SDK this week. The main change in this that we have changed the default level of abstraction when building clean rooms using the SDK, more closely mirroring the graphical UI experience. This is a breaking change, users that wish to continue using the old syntax may continue to do so by using the legacy module.
  • Additionally we added new helper functions to make it less verbose to: discover appropriate confidential computing enclave specifications for a given clean room if the enclave version is unknown, verify the identity of the creator of a clean room, and extract the JSON specification of a published clean room.
• Python and R worker libraries: The following libraries are now supported in appropriate python and R workers.
  • Python: seaborn, pyreadstat, streamlit, lifelines, scikit-survival
  • R: lme4, coxme, cmprsk, msm, randomForestSRC
• Minor Improvements
  • Retargeting/Lookalike integration: retargeting audiences and lookalike audiences are now displayed in a single activation UI tab. Data labs may now be provisioned to retargeting-only clean rooms, instead of provisioning matching data directly.
  • Data lab versions: Data labs now have versions, and there is a version compatibility check between the clean room and data lab during provisioning. Incompatible versions are explicitly reported in error messages if they occur during provisioning.
  • Faster UI: most common tasks in the UI now make fewer calls to the API, speeding performance, especially over higher latency connections or periods of heavy website load.

Bugfixes

• Fixed a vulnerability in the Airlock feature where an attacker could raise error messages that exceeded the expected preview budget.
• Fixed an issue where very wide but short training data sets may fail unexpectedly when used for synthetic data generation.
• Fixed an issue where errors would not be reported in the UI if raised during synthetic data generation in some configurations.
• Fixed an issue where clean rooms with a reprovisioning rate limit would report a generic provisioning failure if it failed due to the rate limit. Rate limit failures now have their own error message to make this behavior more clear.
• Fixed an issue where creating too many audiences in the same UI session could cause the UI to report metering errors in some scenarios.

v3.9 - 11/10/23

New features

• Lookalike Clean Room improvements: Duplicated rows in advertiser datasets will be automatically removed. Publishers can export activated audiences using data connectors. Both can now see the detailed Lookalike Clean Room configuration and can stop it Lookalike Clean Rooms. Insights and audiences computations of Lookalike Clean Rooms are now executed simultaneously, and it is possible to retry in case of errors.
• CSV upload improvements: now it is possible to select which decimal separator is being used in the dataset (dot or comma) and the CSV column delimiter is automatically detected.
• Column uniqueness constraints: when creating a table, you can now indicate which column or column combinations must have unique values. This will be validated when a dataset is provisioned to the table.
• More data connectors available: you can now import data from Salesforce, as well as export audiences directly to Google Ad Manager.

Bugfixes

• Fix an issue that prevented SQL computations to execute on tables with spaces in the name.
• Fix an issue that reported N/A values in the Lookalike Clean Room Insights table (they should have been filtered out).

v3.4 - 27/04/23

New features

• Keychain & Dataset reprovisioning: when uploading a new dataset to the platform, its encryption key can be confidentially stored in the Decentriq Keychain. Among other features, the Keychain enables you to reuse datasets across data clean rooms without having to re-upload them. It operates like a traditional password manager, deriving from your password an encryption key used to encrypt the secrets you store in the Keychain. Decentriq does not have access to your password, and can never access the secrets stored in the Keychain.
• Media Data Clean Rooms participants and roles: it is now possible to create Media Data Clean Rooms with multiple users representing the Publisher and the Advertiser. This release also introduces the role of the Agency, which can support the Advertiser analysing and choosing the best audiences to activate.
• Export Media Data Clean Rooms results: you can now export the overlap insights and the top affinity segments to CSV.
• UX improvements: Filter the "Overview" tab to show only actionable items. Enhanced the visibility of provisioned datasets.

Bugfixes

• Including certain special characters in the computation name could disrupt its execution.
• In a few cases, the Decentriq UI was not displaying updated information about which Data Owners would be required to approve a new computation request.

Enclave versions

• No enclave changes, please refer to v3.3 below.

v3.3 - 30/03/23

New features

• Admin Portal: as an organization admin, you now have a dedicated interface to manage internal users, invite external users to DCRs, and get an overview of all DCRs and collaborating organizations on a monthly basis.
• Azure Marketplace: You can now subscribe to the Decentriq Platform directly through the Azure Marketplace. Your billing is managed in Azure while your users and DCR activities can be managed in the Decentriq Admin Portal. Contact us for an offer specific to your needs.
• No-code Join: a new computation type that allows you to select two tables and match their columns based on conditions. Data privacy is ensured by letting analysts only see statistics about the resulting join, while the data itself can be queried by downstream computations.

Bugfixes

• Fixed an issue preventing some users to provision datasets with empty values on numeric column types.
• Some users were unable to access datasets in existing data clean rooms.
• Small UI improvements in the Media Clean Rooms.

v3.0 - 05/01/23

We are pleased to share that the version 3.0 of the Decentriq Platform is now officially available to all our customers.

This is the result of a major engineering effort, focused on security, scalability and resilience.

What's new in version 3.0

• With this release, Decentriq becomes the world’s first analytics platform deployed in production properly using AMD SEV-SNP. This means more memory available to the enclaves while keeping strong security assurances.
• All sensitive data is hosted and processed exclusively in Switzerland. Auxiliary services are based in the EU only.
• Enhanced resource distribution system to reduce latency, allowing you to run computations even when the platform is being heavily used.
• Revamp of the internals to make the platform future-proof for upcoming feature development.

Additional features

• Larger datasets support: provision Gigabytes of data directly in the Decentriq UI, and run computations on much larger workloads.
• Improved synthetic data generation: you now can choose whether to use differential privacy-based or a standard model to synthesize your dataset. The standard model has better pairwise correlations and supports larger datasets.
• S3 bucket integration: your computation results can be uploaded directly from a data clean room to your S3 bucket, following high security standards.
• Data clean room password: it is now possible to set a data clean room password that is shared out of bands. If set, any interaction with the data clean room requires knowledge of the password.
• New documentation: revamped documentation page suitable for all levels of expertise, from step-by-step guides to advanced API reference.

v2.2 - 20/06/22

New features

• Computation requests: So far, Data Clean Rooms have been immutable. This made it necessary to create new Data Clean Rooms to run different computations on the same data. Now it is possible to request additional computations in existing Data Clean Rooms which were not part of the original specification. Of course the Data Owners have to approve first in order to continue guaranteeing the security of the data. To do this, when you create a request, the platform automatically determines the owners of the affected datasets and asks them for approval. Once all approved, the new computation can be added to the Data Clean Room.
• Development tab: This is a scratch space that allows you to run arbitrary computations on data and results you already have access to without the need for approval. This allows prototyping computations which subsequently can be turned into a request.
• Join then synthesize: Our UI now allows you to create synthetic data not only based on tables, but also based on the output of a SQL computation. This allows generating synthetic copies of joined datasets from multiple sources, enabling much richer synthetic datasets.
• Privacy filter for individual computations: You can now set an independent k-anonymity privacy filter for each SQL computation, previously this was only possible globally.
• Mandatory datasets: You can now set which tables and files must be provisioned before allowing running computations that depend on them.
• New UI look: We did our spring cleaning and removed several borders and other unnecessary elements. We hope you like it too!
• UX improvements: Several enhancements in order to improve the experience of writing and debugging code into the platform, and preparing the Data Clean Room draft.
• New Python SDK version: A new version of the Python SDK, version 0.11.0, has been released with support for all new features available in the platform.

Bugfixes

• Removed some performance bottlenecks for large Data Clean Rooms.
• Pagination bug in ‘My Datasets’ page is fixed.
• The list of Data Clean Rooms in the sidebar is now updated automatically after creating a new one.
• It is now possible to have multiple files as dependencies for computations.

v2.0 - 07/03/22

We are delighted to announce that the Decentriq platform version 2.0 is released! We are introducing compute nodes that support the execution of Python scripts. This opens the door to confidential machine learning and other exciting applications in order to unlock the value of your sensitive data assets, all powered by confidential computing! Available in Switzerland and globally.

What's new in version 2.0

• The most important improvement is our new compute graph-based platform architecture: the Decentriq platform now consists of driver and worker enclaves. While the driver enforces the Data Clean Rooms permissions and orchestrates the execution, the worker enclaves execute the computations. This architecture allows us to combine different trusted execution environment technologies according to their strengths: Intel SGX, AMD SEV/SNP, AWS Nitro...
• Processing your datasets just got more powerful! Besides writing SQL queries, you can now take your analyses to the next level by writing Python scripts, also running on confidential computing!
• Brand new Python SDK, fully compatible with Data Clean Rooms created using our web platorm. Your entire workflow can be automated: manage Data Clean Rooms, datasets and analyses programmatically. Documentation and step-by-step guides available.

Additional Features

• Tables and files browser: writing a query or script is made easier now by just having all available tables, columns and files in a handy side panel.
• Several UI improvements: finding your way in the UI is just getting more intuitive and efficient.

Bugfixes

• When importing a Data Clean Room from a file, the description field was not being read correctly.
• Switching between Data Clean Rooms was slightly time consuming.
• Some brand logos were cropped.
• Some error messages were not very intuitive.

Enclave versions

The following enclave versions will be available.

v1.4 - 03/09/21

New features

• Data deletion: Now, when you delete your dataset, also all the results, derivated datasets and metadata get deleted from the encrypted data store.
• Improved multitenancy: Enclaves now prioritize fast requests (such retrieving the audit log or the Data Clean Room definition) over longer running tasks (executing queries) to give you the best possible user experience.
• Data Clean Room stopping: The Data Clean Room creator can now stop the Data Clean Room, so that no participant can upload datasets nor run queries. Stopped Data Clean Rooms still allow data deletion and retrieving the audit log.
• Major changes of Data Clean Room creation UI/UX: The UX of the Data Clean Room creation has been improved thanks to several changes: Modifications of titles or elements are now auto-saved, you can re-order table columns easily, the Data Clean Room creation elements are easier to modify, and multiple styling improvements.

v1.3 - 16/08/21

New features

• Privacy filter: To protect the privacy of individuals, we implemented a configurable privacy filter that enforces a minimum level of aggregation in the output. If enabled, only aggregating queries (with a GROUP BY in the last step) are allowed and all resulting groups with less than a specified threshold are filtered out before being returned to the Analyst.
• Result file naming: Result files are now named according to the query.
• Various small UI/UX improvements

Bugfixes

• Fixed a rare concurrency issue when executing long-running queries that could lead to a situation where the query never seems to finish.
• 'Last edited' timestamp bug has been fixed.
