http://www.peertopatent.org/patent/20080077604/activity In an embodiment, the invention provides a method of de identifying an object data. The method comprises steps of obtaining the object data, the object data being data concerning a medical object, identifying at least one confidential identification data in the object data, the confidential identification data being a confidential data for identifying the medical object, filtering the confidential identification data from the object data and replacing the confidential identification data with at least one standard character. en-us Methods of de identifying an object data "Building an anonymized catalogued radiology museum in PACS: a feasibility study" also looks potentially interesting as prior art, but I cannot find a free copy of the entire treatise, only this abstract: http://bjr.birjournals.org/cgi/content/abstract/79/944/666 which by itself doesn't appear to offer more than the existing examples of prior art here.

Presumably its contribution may be centered in this area. I notice that the description does suggest that one can anonymize various kinds of secondary data, but I'm not satisfied it does a good job teaching how to do that. I found herein two approaches for non-text data: (1) convert to text, anonymize, convert back, and (2) define what a confidential wave-form looks like, and find/replace it in the wave-form data. I can understand how (1) works, at least where the secondary data type already has conversions to and from text defined (as I don't see any such method elaborated here). It may just be my ignorance of this specfic method, but the description for (2) in the application is not very satisfying. E.g. the application says "The object data being present in the frequency domain waveform format, the element of the object data matching a predetermined frequency can be identified as a confidential identification data." I guess confidential data somehow has a unique frequency? Anyway, aside from these methods, the application seems to simply go back again and again to the notion of "find confidential data and replace it", which does not seem by itself to be a novel concept.

In that regard, it's reasonable to raise HIPAA itself. However, note that the applicant has narrower depedent claims that might warrant some attention as well as more detailed disclosure which may be able to support more narrowly drafted claims, particularly relating to specifics about data structures and filtering mechanics. Some focus in that direction might be useful.

Attempting to patent the common implementation of a standard is not without precedent :-) However, as the law's been in effect for several years already, it seems that there should be prior art out there that would defeat any trivial implementation of it.

The terms "object" or "medical object" refer to a person/patient. The gist of the invention is to locate and replace confidential identification data in a medical document.
