Control Data Analysis Processing System

Privacy Impact Assessment – Control Data Analysis (PCD) Processing System

PCD System Overview: 

The Control Data Analysis System (PCD) utilizes data from the IMS-Control-Data (SCF0104) to provide management with the period and cumulative information on the number of documents that are errors, rejects, blocks out of balance, S.C. and MCC deletes.  This printed information is provided by specific WP & C program codes and used as the data source for certain reports required by the National Office.  In addition, the output provides management with specific inventory volumes, as well as receipt and processed volumes.  The information is used to identify processing programs with which Service Centers may be experiencing difficulty as indicated by large volumes of errors, rejects or bob blocks.  Output reports consist of IMF, BMF, EPMF, IRP and NMF Error and Reject Block Proof Summaries, BOB Analysis and Block Deletion Analysis.  In addition, PRODUCTION-ADJUSTMENT (PCD0330) and BATCH-AND-PRODUCTION-CONTROL (PCD0331) records for input to the Daily Service Center Production Control and Performance Reporting (Project PCC) and Reject Reinput Transmittals are produced.

Yes -  The PCD system uses the data to produce analysis and summaries of            various inventories by program number to Service Center management.

4. How will each data item be verified for accuracy, timeliness, and completeness?

Based on various elements in the DLN such as blocking series, control day key and Saturday/Sunday key, a program code is validated through other input files used in the PCD system for validation purposes. 

5. Is there another source for the data?  Explain how that source is or is not used.

No. There is no other source for the data.

6. Generally, how will data be retrieved by the user?

Access to the Data

8. Who will have access to the data in the system (Users, Managers, System Administrators, Developers, Others)?

PCD is a set of computer programs set to run in a specified order on the UNISYS Mainframe.  PCD does not have any end-users; only System Administrators and the Accountant Unit at the computing centers have access.

Application developers do not have access to production system; if the need arises, the developer can obtain read-only access to the production environment.  This access is terminated after the access is no longer needed.  Only privileged users are allowed to load software to the system.  

9. How is access to the data by a user determined and by whom? 

Unique Mainframe usernames and passwords are required for system authentication.  An OL5081 is required of IRS users requesting access to PCD, via the UNISYS Mainframe, and must be signed by an immediate manager.  Once forms are approved they are submitted to the system administrator, who adds the new user’s account into the system.  User accounts are disabled after 45 days of inactivity. 

10. Do other IRS systems provide, receive, or share data in the system?  If YES, list the system(s) and describe which data is shared.  If NO, continue to Question 12.

Yes.  The PCD system provides processing Production Control Records and Production Adjustments for input to the Daily Production Report (DPR) and Reject Reinput Transmittals.

11. Have the IRS systems described in Item 10 received an approved Security Certification and Privacy Impact Assessment?

GMF and SCCF have approved PIAs.

12.  Will other agencies provide, receive, or share data in any form with this system?  No.

13.  What are the procedures for eliminating the data at the end of the retention period?

The PCD system will initialize each program number and inventory columns to zero at the beginning of each processing year.

14.  Will this system use technology in a new way?  If "YES" describe. If "NO" go to Question 15. 

No.  The PCD system is not using technology in a new way.
