RECTIFICATIF TECHNIQUE 1
Technical Corrigendum 1 to ISO/IEC 19794-2:2005 was prepared by Joint Technical Committee ISO/IEC
JTC 1, Information technology, Subcommittee SC 37, Biometrics.
In this corrected version, Table 16 and the associated Notes 2 and 3 have been replaced. Also, the first
paragraph of Clause 8 and the subclause numbering throughout Clause 8 have been modified.

Page vi, Introduction
In paragraph 2, replace sentence 2 with the following:
Ten types of data formats are then defined:
⎯ two for general storage and data interchange; one of minutiae data only and one including also standard-
ised extended data;
⎯ two normal-size format types without record header for use in card-based systems — one with ridge
endings represented by valley skeleton bifurcation points and one with ridge endings represented by ridge
skeleton end points;
⎯ two compact-size format types without record header for use in card-based systems — one with ridge
endings represented by valley skeleton bifurcation points and one with ridge endings represented by ridge
skeleton end points;
⎯ two normal-size format types with record header for use in card-based systems — one with ridge endings
represented by valley skeleton bifurcation points and one with ridge endings represented by ridge skeleton
end points;
⎯ two compact-size format types with record header for use in card-based systems — one with ridge
endings represented by valley skeleton bifurcation points and one with ridge endings represented by ridge
skeleton end points.

Page 22, Clause 8
Replace the first paragraph with the following:
8.1 Introduction
This clause defines two card-related encoding formats for a series of minutiae descriptions. These are the
normal size format and the compact size format. When either of the card formats is used, a series of minutiae
descriptions as defined in 8.2 or as defined in 8.3 may be embedded in
⎯ a tag-length-value encoded biometric data DO as defined in ISO/IEC 7816-11, or
⎯ a finger minutiae record as defined in Clause 7, instead of a series of fixed-length (6-byte) minutiae
descriptions.
Pages 22–26
Renumber original 8.1, 8.2, 8.3 and 8.4 as 8.2, 8.3, 8.4 and 8.5, respectively. Renumber their subclauses
accordingly.
Page 23, 8.3.1
Replace all occurrences of “Annex C” with “Annex D”.
Page 23, 8.3.2
In paragraph 1, replace sentence 2 with the following:
They can be encoded as DOs embedded in a matching algorithm parameter template as defined in
ISO/IEC 19785-3:2007, Clause 11.
Page 23, 8.3.3
In the last paragraph, replace “Annex C” with “Annex D”.
Page 26, 8.4.1, Table 13
In the row for the DO with tag ‘94’, replace the entry in the column “Value” with the following:
Zonal quality data acc. to 8.4.1.1
Page 26, clause 8.4.1
Add the following new subclauses before 8.4.2:
8.4.1.1 Zonal Quality Data Modified for Finger Minutiae Card Formats
8.4.1.1.1 Zonal Quality Data Format Summary
In the absence of a record header, for the finger minutiae card formats the image size in the X and Y directions
is not provided; hence, the placement of the cells described in 7.5.4 is unknown. This information has to be
provided in a modified header for the zonal quality data.
