De-identified patient data is patient data that has been removed of important identifiers such as birth date, gender, address, and age. De-identified patient data is often used for research.
Introduction
Information is de-identified when it is not possible to 'reasonable ascertain' the identity of a person from that data. The definition of Irreversible de-identification of data is context driven. The capacity of re-identify de-identified data may depend critically on particular resources( Intellectual, Information Technology, Access to multiple data sets).(1) Efforts are being made to automate the anonymization of health information by developing de-identifications models that can successfully remove personal health information.

De-identified patient data, according to the Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule , refers to the patient data set following the removal of all HIPAA specified patient identifiers from it. There are 19 identifiers that make up a patient’s protected information, and include the individual’s name, address, dates directly related to the individual, all ages over 89, telephone number, fax number, email address, Social Security number, Medical Record number, Health Plan number, Account numbers, Certificate or License numbers, Vehicle Identification numbers, Device Identification numbers, Universal Resource Locators, Internet protocol Address, Biometric identifiers, full face photographs and images, and any other unique identifying number, characteristic or code. HIPAA allows the use of such de-identified data without requiring special authorization, and its use or disclosure without restrictions.
