About Restricted-Use Contractual Data
The more extensive restricted-use data, available by contractual agreement, will be distributed only to certified researchers who commit themselves to maintaining limited access. To be eligible to enter into a contract, researchers must have an IRB-approved security plan for handling and storing sensitive data and sign a data-use contract agreeing to keep the data confidential. Contractual data are provided in separate, linkable datasets and contain a hidden signature identifying the purchaser.
