How much redaction is necessary to anonymize an electronic health record

Discuss in 500 words, how much redaction is necessary to anonymize an electronic health record. Is it enough to redact the name? The name and address? Is a medical record like a finger print?

Include at least one quote from 3 articles, place them in quotation marks and cite in-line (as all work copied from another should be handled).

Cite your sources in a reference list at the end. Do not copy without providing proper attribution (quotation marks and in-line citations). Write in essay format not in bulleted, numbered or other list format.
