This proprietary patent-pending technology gives healthcare enterprises full control over patient data security. The DCMSYS Unifier systematically de-identifies PHI (Protected Health Information) in compliance with Safe Harbor directives by removing personal identifiers such as name, date of birth and social security number so that only the owners of the original data can re-identify the patient as needed. These additional security measures are especially important if organizations are storing their patient data off-site. The DCMSYS Unifier and VNA handle de-identification and re-identification on the fly, using a unique secure key to encrypt and decrypt the data. We also guarantee irreversible anonymization as required.
