A highly secure networked system and methods for storage, processing, and transmission of sensitive information are described. Sensitive, e.g. personal/private, information is cleansed, salted, and hashed by data contributor computing environments. Cleansing, salting, and hashing by multiple data contributor computing environments occurs using the same processes to ensure output hashed values are consistent across multiple sources. The hashed sensitive information is hashed a second time by a secure facility computing environment. The second hashing of the data involves a private salt inaccessible to third parties. The second hashed data is linked to previously hashed data (when possible) and assigned a unique ID. Data dictionaries are created for particular individuals provided access to the highly secure information, e.g. researchers. Prior to a data dictionary being accessible by a researcher computing device, the data dictionary undergoes compliance and statistical analyses regarding potential re-identification of the source unhashed data. The data dictionaries are viewable by researchers as certified views via a secure VPN. |
