The underlying storage infrastructure in use by Yale University Library’s Hydra repository is now 3-Lock data compliant.  Data and information at Yale is classified into three different tiers to categorize data security (more here).  3-Lock data can include things like Social Security numbers, credit card numbers, trade secrets, medical records, tax records, grades for assignments and courses, passport numbers, Veterans Administration data, and bank account numbers.  This upgrade is intended to meet the needs of units across the Library depositing material, and in particular units that are interested in the storage of digital personal papers that may contain sensitive content.  Thanks to Steve DeGroat and John Coleman of the Design & Quality Assurance team within Yale ITS Infrastructure Services.
