Periodically, bulk exports of deidentified study data are produced by Bridge server for each study, and posted on Sage's data sharing platform, Synapse. Each study PI will have some control over the timing of data releases to Synapse, but we anticipate that new versions of datasets become available on the order of a few days to weeks, not in real time.
Administrative access to Bridge Server
Administrative access to Bridge Server cloud service providers is limited to the Director of Engineering (Currently Michael Kellen) and members of the Bridge Server Engineering team (Currently Eric Wu, Dwayne Jeng, and Alx Dark). Access will be granted, revoked as members leave this team. All individuals must access these systems through individual accounts. Passwords must be at least 8 characters, and consist of a mix of at least 3 of these 4 character types: uppercase, lowercase, numeric, and special characters. Passwords should not be shared across different services, and must be rotated at least annually.
All Bridge server work should use accounts dedicated for supporting test, staging, or production instances of Bridge server, and not support any other Sage projects.
Confidential PII should not be moved from Bridge Server infrastructure components and placed on any personal workstation, laptop, or portable media.
Revoking / Resuming Data Sharing
...
An administrative-only API call can be made by Bridge technical admins to permanently delete a users user's account and all associated data from Bridge server if requested by a user.
Note, even after a Bridge account has been deleted, it is not possible to pull back data already distributed to researchers. This fact is explained to users during the informed consent process which much be completed to enroll.
Retention after Study Completion
Bridge is not intended to be a long-term storage solution for mobile health studies. At the end of a study, all data in the system for that study will be purged from the system. Coded study data may be maintained as a researcher resource by Sage in our Synapse system, or managed by the study team.
