Even encrypted medical record databases leak information
A new study from Microsoft researchers warns that many types of databases used for electronic medical records are vulnerable to leaking information despite the use of encryption.

Researchers discovered gender, race, age and admission information, among other data, using real patient records from 200 U.S. hospitals.
In the light of increasing cyberattacks against the health care industry, the researchers recommended that the systems they studied "should not be used in the context of" electronic medical records.
