The ICBM Database has been constructed to provide an effective means for archival and protection of collaborator collected image data. The goal of this software is to provide a convenient mechanism for searching the existence of particular image data while protecting its usage at the same time.
In terms of the physical presence of the acquired data, at least 5 explicit copies of all subject data exist: 3 at the site of origin, and 2 at ICBM:
A. At each site:
- Source data
- Copy on local workstation
- Explicit archive copies of subject data on CD
B. At ICBM
- ICBM database
- Explicit archive copies of subject data on tape at ICBM
To ensure data safety, regular backups are made of all data sets. Archival tapes are kept in two separate physical locations. The participating sites are responsible for backing up the data locally.
The user authentication procedures described above are flexible enough to allow any user or user group access to any part or all of the database for read or write operations. Write access to the database is restricted to ICBM personnel to ensure database integrity. Individual sites are able to access all data originally collected at their own institution.
