CommCare’s De-Identification Export allows a user with secure access to CommCare HQ to download data that can be analyzed for specific outcomes, but makes the personal identity of the cases unknown to the data analyst. CommCare applications may contain both personal identifying information and sensitive information.

CommCare's De-identification Function

This type of information includes:

...

By combining sensitive information with common identifiers such as date of birth, geographic location, or sex, the information could be used to identify a single person. On the data collection side, CommCare requires all users to log in with a secure, unique identification. The data is then securely hosted and is encrypted using RSA 256-bit encryption.  All interactions on the CommCareHQ website are conducted using industry standard transmission encryption.  CommCareHQ reports are only made available to users with appropriate access to public health information. However, it is the responsibility of users with access to data in their project spaces to make sure that it is shared appropriately.

Note about sensitive data

• Sensitive IDs - any field marked as a sensitive ID will be replaced with a random alphanumeric code. This code will be consistent within forms; that is if you are treating owner_id as a sensitive field and owner_id is the same in 10 form submissions, then it will be replaced with the same code in all of the form submissions.

• Sensitive dates - dates are shifted by up to one month, randomly. However the length of the shift is consistent within a given form or case. So if in one form you ask both mother's date of birth and child's date of birth, both dates will be shifted by the same number.

Download your Deidentified Report

Downloading de-identified report is a three-step process:

1. Select a Form Export

Create or select a form export: Information to create a form export is located here. To select an existing form export go to:

CommCareHQ -> Data -> Export Data -> Export Forms -> Exports and select “Edit” for the export you want to download with de-identified data. Scroll to the bottom of the page to the Privacy Settings.

2. Configure Privacy Settings

This allows the user to select form data to be de-identified so when the data is exported to an excel sheet, the columns will still be in the data export but the data values will not contain personal information that can be tracked to a single beneficiary           

...

3. Once you have marked the sensitive fields, scroll all the way down to Privacy Settings and check the box "Publish in De-identified Export". Checking this box will make the export appear as a "De-identified Export" on the form export page. By checking this box, you are confirming that you have excluded or marked as sensitive all identifiable information, and users who only have access to de-identified data may access this export.
