System and method of fraud and misuse detection

1. A method of detecting improper access of a patient's protected health information (PHI) in a computer environment, the method comprising:

generating a rule for monitoring audit log data representing at least one of transactions or activities that are executed in the computer environment, which are associated with the patient's PHI, the rule comprising at least one criterion related to accesses in excess of a specific volume, accesses during a pre-determined time interval, accesses by a specific user, that is indicative of improper access of the patient's PHI by an authorized user wherein the improper access is an indication of potential snooping or identity theft of the patient's PHI, the authorized user having a pre-defined role comprising authorized computer access to the patient's PHI;

applying the rule to the audit log data to determine if an event has occurred, the event occurring if the at least one criterion has been met;

storing, in a memory, a hit if the event has occurred; and

providing notification if the event has occurred.

2. The method of claim 1 , further comprising:

normalizing the audit log data to be correlated with known fields based on template information.

3. The method of claim 1 , further comprising:

obtaining role information of the authorized user; and

wherein the generated rule is based on a user's specific role.

4. The method of claim 1 , wherein application of the rule to the audit log data comprises determining a misuse of the patient's PHI by tracking access by the authorized user of patient's PHI of another person.

5. The method of claim 4 , wherein the access tracked comprises access by the authorized user in excess of a specific volume of the patient's PHI of the another person.

6. The method of claim 5 , wherein the access tracked further comprises access over a predetermined time interval.

7. The method of claim 4 , wherein the criterion related to the audit log data comprises a relation between the authorized user and the another person sufficient to detect at least one of family member snooping, VIP snooping, co-worker snooping, whole other family snooping.

8. The method of claim 1 , further comprising:

accessing at least one of select patient's PHI or select user data; and

applying the rule further comprises applying the rule to at least one of the select patient's PHI or the select user data.

9. The method of claim 8 , wherein applying the rule to the audit log data and the select patient's PHI comprises analysis of criteria including access by the authorized user of patient's PHI of the another person who was discharged from a medical facility more than a specified time period in the past.

10. The method of claim 8 , wherein applying the rule to the audit log data and the select user data comprises tracking access by the authorized user of patient's PHI of the another person, where the authorized user is a remote physician staff member and the another person is a patient not under the care of the physician for whom the authorized user is a staff member.

11. The method of claim 8 , wherein applying the rule to the audit log data and the select user data comprises tracking access by the authorized user of patient's PHI of the another person during a timeframe outside the normal work shift of the authorized user.

12. A system for detecting improper access of a patient's protected health information (PHI) in a health-care system computer environment, the system comprising:

a user interface for selection of at least one criterion related to accesses in excess of a specific volume, accesses during a pre-determined time interval, accesses by a specific user, representing at least one of transactions or activities associated with the patient's PHI that is indicative of improper access of the patient's PHI within the health-care system computer environment by an authorized user wherein the improper access is an indication of potential snooping or identity theft of the patient's PHI, the authorized user having a pre-defined role comprising authorized computer access to the patient's PHI, and for selection of a schedule for application of a rule for monitoring audit log data representing at least one of the transactions or the activities;

a microprocessor in communication with the user interface and having access to the audit log data representing the transactions or the activities of the patient's PHI, the microprocessor generating the rule based at least in part on the at least one criterion selected and applying the rule to the audit log data according to the schedule selected in order to determine if an event has occurred,

wherein the event occurs if the at least one criterion has been met,

wherein the microprocessor stores a hit if the event has occurred, and

wherein the microprocessor provides notification if the event has occurred.

13. The system of claim 12 , wherein application of the rule to the audit log data comprises determining a misuse of the patient's PHI by tracking access by the authorized user of patient's PHI of another person.

14. A non-transitory computer-readable medium with computer-executable instructions embodied thereon for performing a method of detecting improper access of a patient's protected health information (PHI) in a health-care system computing environment, the method comprising:

providing a selection of a criterion related to accesses in excess of a specific volume, accesses during a pre-determined time interval, accesses by a specific user, representing at least one of transactions or activities associated with the patient's PHI within the health-care system computing environment, wherein the criterion is indicative of improper access of the patient's PHI by an authorized user wherein the improper access is an indication of potential snooping or identity theft of the patient's PHI, the authorized user having a pre-defined role comprising authorized computer access to the patient's PHI;

generating a rule based at least in part on the criterion for monitoring the at least one of the transactions or the activities;

providing a selection for a schedule for application of the rule to the at least one of the transactions or the activities;

applying the rule according to the schedule selected to the at least one of the transactions or the activities to determine if an event has occurred, the event occurring if the criterion has been met;

storing a hit if the event has occurred; and

providing notification if the event has occurred.

15. The non-transitory computer-readable medium of claim 14 , wherein the providing the criterion is indicative of fraudulent claims filed by the authorized user of the health-care system computing environment with authorized access to the patient's PHI.

16. The non-transitory computer-readable medium of claim 14 , wherein application of the rule to the audit log data comprises determining a misuse of the patient's PHI by tracking access by the authorized user of patient's PHI of another person.

17. The non-transitory computer-readable medium of claim 16 , wherein the access tracked comprises access by the authorized user to a predetermined number of patient's PHI of the another person.
