What are the values for the Data Classfication Tag Scheme?

 

Explanation of Data Classification Tag Scheme:

When the text is encrypted, a tag of size 1 byte is added in the front of the text and then encrypted. This tag is to flag the type of data being encrypted. If the tag is e.g. LUK, it implies this data is super sensitive and should not be decrypted to clear outside the secure zone.

 

This tag is added in front of the encrypted data elements as a one byte header. Up to now I found out that the following values do exist: 

21 = PAN

22 = LUK

23 = Token

26 = ICC Private key

 

Is anybody aware of any further values and what they are meaning?

Hallo Diana,

globally speaking about the VTS APIs using JWS/JWE. The data Classification Tag 21 and 23 were implemented with Visa_Token_Services_Issuer_API_v2.2., but are not yet documented in the specification. Tag 22 and 26 are used on the Token Requestor APIs.

Thank you

Hello,

 

Thank you for being part of the community forum! Documentation is unavailable publically at this time, the program is tightly held, but when the documentation does becomes available, it will be available within the Visa Developer site.

 

Thank you,
