Excerpt
Excerpt We define a new approach to locating and
replacing personally-identifying information in
medical records that extends beyond straight search-and-replace procedures, and we provide techniques
for minimizing risk to patient confidentiality. The
straightforward approach of global search and
replace properly located no more than 30-60% of all
personally-identifying information that appeared
explicitly in our sample database. On the other hand, our Scrub system found 99-100% of these references. Scrub uses detection algorithms that employ templates and specialized knowledge of what
constitutes a name, address, phone number and so
forth. |

Claims
1
A method of de identifying an object data, the method comprising:
obtaining the object data, the object data being a 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.
Relevance
After avoiding obfuscation of terms ("medical object" means "patient"), and allowing "at least one standard character" to refer to some general replacement string (since the application does not clearly define its limit, only offers certain examples of what it might be), I believe that the independent claims here are entirely anticipated by this example of prior art.

11
A method of de identifying a secondary object data in an object data, the method comprising:
obtaining the object data, the object data comprising a primary object data and the secondary object data;
identifying at least one confidential identification data in the secondary object data, the confidential identification data being a confidential data for identifying the medical object;
filtering the confidential identification data from the secondary object data; and
replacing the confidential identification data with at least one standard character.

19
A computer program product stored in a computer readable media for de identifying an object data, the computer program product comprising:
a routine for obtaining an object data, the object data being data concerning a medical object;
a routine for identifying at least one confidential identification data in the object data, the confidential identification data being a confidential data for identifying the medical object;
a routine for filtering the confidential identification data from the object data; and
a routine for replacing the confidential identification data with at least one standard character.

With regard to claim 19 specifically, the "Scrub" paper describes a computer program product.
