National Change-of-Address

Linkage System-NCOALink

USPS Confidential. Restricted Distribution

purpose of today s briefing
PURPOSE OF TODAY’S BRIEFING
  • Advise you of a new, secure change-of-address technology developed by Address Management
  • Demonstrate how NCOALink supports current USPS® (United States Postal Service®) and Mailing Industry Task Force initiatives
slide3

SECURE DATA STORES BREAKTHROUGH “TECHNOLOGY”

  • NCOALink represents a breakthrough technology for securely storing data
  • Massive volumes data can be released in a manner that allows “revelation” to occur only in accordance with presentation of valid “authorizing” request
  • USPS has a patent application being processed for this new technology

NATIONAL CHANGE-OF-ADDRESS (NCOA)

Value of the National Change-of-Address Program:“Conversely, the rehandling costs avoided by USPS in FY 1998 as a result of not having to forward mail when individuals, families, and businesses move was estimated at $1.194 billion.” 1

SAMPLE NCOA CHANGE-OF-ADDRESS DATA

This example represents a typical customer change-of-address. This is also typical of the “text’ representation shown in NCOA.

SAMPLE NCOALINK CHANGE-OF-ADDRESS DATA

This example represents what a typical customer change-of-address will look like within the NCOALink System.

secure hash algorithm sha
SECURE HASH ALGORITHM (SHA)

The Secure Hash Algorithm (SHA) is a FIPS standard, data encoding technique that produces a mathematical value unique to every name/address combination presented

To build the NCOALink database, we combine the customer name and pertinent address data:

standard hash algorithm
STANDARD HASH ALGORITHM

We then generate a SHA of the information, producing our “NCOALink Search Key”

hiding the new side address data
“HIDING THE NEW SIDE ADDRESS DATA”

This is the NCOALink KEY that will be used:

  • By USPS to install data representing customer’s new address into 8 separate hash tables
  • By customer to retrieve the data required to reconstruct the new-address text

No physical relationship between the data stored into the 8 tables exists

retrieving the new side address
“RETRIEVING THE NEW SIDE ADDRESS”

Customer processes their address data according to USPS prescribed method:

  • Generates SHA using name and address data the same way USPS did in creating the NCOALink database

RECREATING THE NEW-ADDRESS INFORMATION

After the new-address DPBC is derived, a reverse lookup into the ZIP+4® database using the DPBC produces the new-address text:

SATISFIES OF GAO RECOMMENDATIONS
  • Removes potential that Change-of-Address information can be “data-mined”
  • Complies with Title 39 prohibition and Privacy Act restriction regarding release of name and address data
external security evaluation excerpt
EXTERNAL SECURITY EVALUATION (EXCERPT)
  • “Using only the NCOALink files it is considered completely infeasible (that is essentially impossible) for anyone to directly reconstruct the COA files (name, old address, new address and associated data).”
  • “The possibility of forwarding mail in error when it should not be forwarded due to the design of the COA/Link system has been assessed as negligible (essentially zero).”
external security evaluation excerpt1
EXTERNAL SECURITY EVALUATION (EXCERPT)
  • “This is an improvement (in terms of security) and a 1000 times better than the current system.”
  • “Using only the NCOALink files it is considered infeasible to unambiguously reconstruct even one output record.”

USPS Transformation Plan

  • Growth through Added Value to Customers
    • Work with customers … to improve the overall accuracy of address information

SUPPORTS KEY USPS/MAILING INDUSTRY INITIATIVES

Mailing Industry Task Force

  • To make the mail channel increasingly competitive with other communications media
    • … improving address quality
    • Encourage mailers to use methods to correct addresses prior to mail entry
    • Determine if it is feasible to establish a linkage between “intelligent” mail and address quality
