Re: Question about HIPAA Compliance in application development

Thanks Kevin and those who answered me off-list.

It sounds like people generally deal with this through techniques outside of
the application logic itself such as checksums and/or digital signatures on
files / database values that contain protected health information.  My
initial thought was that databases would offer some kind of integrity check
feature and that seems to be the feeling from people on the list as well.

Has anyone actually implemented this kind of control *within* custom
application logic? For example, verifying the integrity of stored protected
health data by (for example) checking that a digital signature is valid
before displaying it back to the user?

Rohit,

Has anyone had to deal with the following HIPAA compliance requirements
within a custom application before:

§164.312(c)(2)
Implement electronic mechanisms to corroborate that electronic
protected health information has not been altered or destroyed in
an unauthorized manner.

§164.312(e)(2)(i)
Implement security measures to ensure that electronically transmitted
electronic protected health information is not improperly modified
without detection until disposed of.

How have you actually implemented these controls in applications? Have
you used a third party tool to do this? Does §164.312(c)(2) simply
boil down to sufficient access control?

Having never had any practical experience with HIPPA, my take on these
sections
may be different (read "wrong") than others, but the way I read these
requirements,
they have to do more with ensuring data integrity than *merely* proper
access
control.

If that is their intent, then I would look at access control as providing a
necessary, but not sufficient security measure to satisfy these
requirements.

Consequently, I would think that a mechanism such as HMACs or digital
signatures
may be appropriate security measures here.
