ANSI X9.119-2 has just been released. It’s an essential standard for protecting your credit card information. Here’s the title: Retail Financial Services – Requirements for Protection of Sensitive Payment Card Data – Part 2: Implementing Post-Authorization Tokenization Systems. It includes the minimum security requirements for implementing tokenization with post-authorization systems to protect sensitive payment card data.
The standard was developed by professionals in the industry. Both commercial and government interests were represented. This token scheme represents a way to make it more difficult for hackers to gain access to your private information during retail transactions.
What is tokenization? It’s the use of a non-sensitive data substitute for information that needs to be protected. This particular scheme is very secure, since the token cannot be de-encrypted except by the valid recipient under any circumstances.
The 64-page ANSI X9.119-2 and its companion standard ANSI X9.119-1 replace the older ANSI X9.119. Taken together, the two standards give you the necessary information you need for implementation. The Part 1 from May of last year covers using encryption methods for retail financial services. The new Part 2 is on the implementation of a class of systems called post-authorization tokens.
The standard is arranged in the usual format. Four opening sections cover scope, referenced documents, terms, and symbols (including abbreviated terms). Section 5 reviews the sensitive payment card elements. Sections 6 and 7 are on tokens and tokenization systems respectively. Section 8 reviews the schema for identification and referencing of tokenization methods.
In addition, Annex A (a required part of the standard) is on the abstract schema. Annex B, also normative, is on acceptable tokenization techniques. Annexes C and D are both informative. They cover static table-driven tokenization reference schemes and token user-cases and guidance.
