First Claim
Patent Images
1. A system for protecting and de-identifying healthcare data, the system comprising:
- a storage device for storing the healthcare data and personally identifiable information for a person; and
a processor in communication with the database, the processor generates an anonymous linking code using a keyed hash function and a second hash function, the anonymous linking code based at least in part on a portion of the personally identifiable information, said processor further appending the anonymous linking code to the healthcare data for the person.

Abstract
A system for protecting and de-identifying healthcare data includes a storage device for storing the healthcare data and personally identifiable information for a person and a processor in communication with the database. The processor generates an anonymous linking code using a keyed hash function and a second hash function. The anonymous linking code is based at least in part on a portion of the personally identifiable information. The processor further appends the anonymous linking code to the healthcare data for the person.

9. A system for protecting and de-identifying healthcare data, the system comprising:
-
at least one data source capable of generating an anonymous linking code using a keyed hash function and a second hash function, the anonymous linking code based at least in part on a portion of personally identifiable information, the at least one data source capable of transmitting healthcare data with the anonymous linking code appended to the healthcare data; and a data warehouse capable of receiving the healthcare data with the appended anonymous linking code and storing the healthcare data with the appended anonymous linking code, the data warehouse associating the received healthcare data with stored healthcare data by matching appended anonymous linking codes. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for protecting and de-identifying healthcare data, the method comprising the steps of:
-
using a keyed hash function to convert a portion of personally identifiable information into a first output; using a second hash function to convert the first output into an anonymous linking code; appending the anonymous linking code to the healthcare data; and removing personally identifiable information from the healthcare data. - View Dependent Claims (16, 17, 18, 19, 20)

21. A system for protecting and de-identifying healthcare data, the system comprising:
-
a data retrieval module receiving healthcare data and its associated personally identifiable information; an extraction and encryption module in communication with the data retrieval module, the extraction and encryption module extracting portions of personally identifiable information for forming an anonymous linking code and encrypting the portions of the personally identifiable information; a concatenation module in communication with the extraction and encryption module, the concatenation module linking together in a predetermined sequence the portions of the personally identifiable information; a first hash function module in communication with the concatenation module, the first hash function module inputting the portions of the personally identifiable information into a first hash function that converts the portions of the personally identifiable information into a first output; a second hash function module in communication with the first hash function module, the second hash function module inputting the first output into a second hash function that converts the first output into an anonymous linking code; a de-identification module in communication with the second hash function module, the de-identification module appending the anonymous linking code to the healthcare data and substantially removing the personally identifiable information from the healthcare data; an encryption for transmission module in communication with the de-identification module, the encryption for transmission module encrypting for transmission the healthcare data and the appended anonymous linking code; a data transmission module in communication with the encryption for transmission module, the data transmission module transmitting the encrypted healthcare data and appended anonymous linking code on a data pathway; the data pathway in communication with the data transmission module; a data reception module in communication with the data pathway, the data reception module receiving the encrypted healthcare data and appended anonymous linking code from the data pathway; a decryption module in communication with the data reception module, the decryption module decrypting the encrypted healthcare data and appended anonymous linking code; a patient linkage module in communication with the decryption module, the patient linkage module linking healthcare data related to the same person; and a report creation module in communication with the decryption module, the report creation module outputting a report based on the healthcare data.
