Identity Data 
Block Type

uint32

Initiates the Identity data block. This value is always 

94

.

Identity Data 
Block Length

uint32

Number of bytes in the Identity data block. This value should always 
be 40: sixteen bytes for the data block type and length fields and the 
source type and ID fields, sixteen bytes for the fingerprint UUID 
value, two bytes for the port, two bytes for the protocol, and four 
bytes for the SM ID.

Identity Data 
Source Type

uint32

Number that maps to the type of data source: 

0

 if the fingerprint data was provided by RNA 

1

 if the fingerprint data was provided by a user

2

 if the fingerprint data was provided by a third-party scanner

3

 if the fingerprint data was provided by a command line tool 

such as 

nmimport.pl

 or the Host Input API client

Identity Data 
Source ID

uint32

Identification number that maps to the source of the fingerprint data. 
Depending on the source type, this may map to RNA, a user, a 
scanner, or a third-party application.

UUID

uint8[16]

If the identity is an operating system identity, the identification 
number, in octets, that acts as a unique identifier for the fingerprint.
