ISO/IEC 19794-14:2013

Information technology — Biometric data interchange formats — Part 14: DNA data

ISO/IEC 19794-14:2013 specifies a data interchange format for the exchange of DNA data for person identification or verification technologies that utilize human DNA. It will provide the ability for DNA profile data to be exchanged and used for comparison (subject to privacy regulations) with DNA profile data produced by any other system that is based on a compatible DNA profiling technique and where the data format conforms to ISO/IEC 19794-14:2013. ISO/IEC 19794-14:2013 is intended to cover current forensic DNA profiling or typing techniques that are based on short tandem repeats (STRs), including STRs on the Y chromosome (Y-STRs), as well as mitochondrial DNA. A single DNA data record for a subject may require data resulting from more than one of these different DNA techniques. ISO/IEC 19794-14:2013 enables data for multiple DNA techniques to be presented in a single record for a given subject. This data format has been prepared in light of ongoing efforts to reduce human involvement in the processing (enrolment and comparison) of DNA. In anticipation of the data format requirements for automated DNA techniques ISO/IEC 19794-14:2013 will describe a format for both processed and raw (electrophoretic) DNA data. Extensible Mark-up Language (XML) encoding of the data is used to specify DNA data interchange. A normative XML Schema Definition (XSD) specification is provided in Annex B. ISO/IEC 19794-14:2013 is not intended for any other purposes than exchange of DNA for biometric verification and identification of individuals; in particular it does not exchange medical and other health-related information.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 19794-14 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information Technology,

Introduction
In the last 20 years, forensic molecular genetics has evolved from a rapidly developing field with changing
technologies into a highly recognized and generally accepted forensic science.
Forensic genetics using deoxyribonucleic acid (DNA) profiling comprises a number of important applications.
Examples are the investigation of biological stains to obtain evidence for the presence of an alleged
perpetrator at a crime scene by comparing the genetic profiles from crime scene samples of human origin, to
those available at DNA databases administrated by legal enforcement agencies. These also include the
identification of unknown corpses in the context of both natural death and of crime, immigration, paternity
testing, and disaster victim identification.
The purpose of this document is to define a standard for the exchange of human DNA identification data. The
standard defines DNA attributes and a data record format for the exchange of DNA data. It includes a sample
record and conformance criteria.
This data interchange format standard is based on DNA data from forensic DNA typing techniques that are
standardized and most commonly used, namely STR profiling and other DNA typing techniques that are
standardized by scientific bodies for the purpose of discriminating between individuals.
Note that the purpose of this data interchange format is to enable the exchange of DNA data from different
systems, not to impose any constraints on the specific DNA typing system/technique to be used.
Where existing DNA data exchange formats have been referenced in the preparation of this document these
formats are listed as references.
Standard profiling systems exploit the non-coding regions of DNA that are referred to “junk DNA”. The coding
regions are deliberately avoided in order to maintain the privacy and civil rights of the donor. However,
national data protection and privacy legislation may impose special security safeguards, such as – but not
limited to – encryption of data transfers and/or storage.

INTERNATIONAL STANDARD ISO/IEC 19794-14:2013(E)

Information technology — Biometric data interchange
formats —
Part 14:
DNA data
1 Scope
This part of ISO/IEC 19794 specifies a data interchange format for the exchange of DNA data for person
identification or verification technologies that utilize human DNA.
It will provide the ability for DNA profile data to be exchanged and used for comparison (subject to privacy
regulations) with DNA profile data produced by any other system that is based on a compatible DNA profiling
technique and where the data format conforms to this part of ISO/IEC 19794.
This part of ISO/IEC 19794 is intended to cover current forensic DNA profiling or typing techniques that are
based on short tandem repeats (STRs), including STRs on the Y chromosome (Y-STRs), as well as
mitochondrial DNA.
A single DNA data record for a subject may require data resulting from more than one of these different DNA
techniques. This part of ISO/IEC 19794 enables data for multiple DNA techniques to be presented in a single
record for a given subject.
This data format has been prepared in light of ongoing efforts to reduce human involvement in the processing
(enrolment and comparison) of DNA. In anticipation of the data format requirements for automated DNA
techniques this part of ISO/IEC 19794 will describe a format for both processed and raw (electrophoretic) DNA
data. Extensible Mark-up Language (XML) encoding of the data is used to specify DNA data interchange. A
normative XML Schema Definition (XSD) specification is provided in Annex B.
This part of ISO/IEC 19794 is not intended for any other purposes than exchange of DNA for biometric
verification and identification of individuals, in particular does not exchange medical and other health-related
information.
2 Conformance
Applications claiming conformance with this part of ISO/IEC 19794 shall be capable of presenting DNA
biometric data as defined by this standard. Minimum conformance shall require the ability to transmit
(exchange) and extract interoperable DNA biometric information.
3 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

6 DNA format specification
6.1 Overview
The DNA record format specified in this document is a structural definition used to exchange DNA data. This
formatted data shall contain the DNA identification data. In conformance to the regulations described in the
ISO/IEC 19794-1, a DNA record should be specified upon the definition of the BDIR or may be embedded in
the biometric data block (BDB) of a CBEFF compliant structure (BIR).
When referring to the objects of a record, they are grouped into three data structures (field, block and record).
A field denotes the elementary one to store data. There are two kinds of fields: simple and combined field. A
simple field contains only one simple data object and a combined field contains one or more fields which may
be a simple or a combined one. One or more data fields can be grouped together into a data block. The part
consisting of several uniquely named components (data fields and blocks) forms a data record.
A whole DNA record according to the BDIR structure is depicted in the Figure 1.
