The 1000 Connectomes Project data sharing effort will provide the research community with open access to datasets contributed by labs around the world. Datasets provided to the 1000 Connectomes Project are to be de-identified prior to deposition of the data with the project (i.e., removal of any personal identifying information from header/support files). Upon arrival, datasets are automatically organized and header files are replaced with novel header files to guarantee that any identifying personal information within the header or supporting files is removed. Prior to open-access sharing via web-based repository, all datasets will be further de-identified and anonymized by the removal of face information from the image to prevent any inappropriate reconstruction of the image that could lead to identification of a participant. Further, each individual participant's dataset will be assigned a randomized five-digit participant identifier, along with a site identifier (two letters which map to the site providing the data). The relationship between the anonymized code and the original subject ID will be destroyed so as to assure that the dataset will be truly anonymized. For each dataset, demographic information provided via web-archive will be limited to (when available): age (18 and up), gender (male, female) and handedness. This information will serve to facilitate more careful characterization of the data, without entailing risk of violation of confidentiality. Datasets will only be included in the repository upon receipt of written expressed permission for usage of the dataset freely by the general public, without limitation.
