This Part of this International Standard defines structures and data elements for biometric information records (BIRs).

This Part of this International Standard defines the concept of a domain of use to establish the applicability of a standard or specification that complies with CBEFF requirements.

This Part of this International Standard defines the concept of a CBEFF patron format, which is a published BIR format specification that complies with CBEFF requirements, specified by a CBEFF patron.

This Part of this International Standard defines the abstract values (and associated semantics) of a set of CBEFF data elements to be used in the definition of CBEFF patron formats.

This Part of this International Standard specifies the use of CBEFF data elements by a CBEFF patron to define the content and encoding of a standard biometric header (SBH) to be included in a biometric information record (i.e., the definition of a CBEFF patron format).

This Part of this International Standard provides the means for identification of the formats of the BDBs in a BIR, but the standardization and interoperability of BDB formats is not in the scope of this Part of this International Standard. It also provides a means (the security block) for BIRs to carry information about the encryption of a BDB in the BIR and about integrity mechanisms applied to the BIR as a whole; the structure and content of security blocks is not in the scope of this Part of this International Standard. Further, the specification of encryption mechanisms for BDBs and of integrity mechanisms for BIRs is not in the scope of this Part of this International Standard.

This Part of this International Standard specifies transformations from one CBEFF patron format to a different CBEFF patron format.

The encoding of the abstract values of CBEFF data elements to be used in the specification of CBEFF patron formats is not in the scope of this Part of this International Standard.

Protection of the privacy of individuals from inappropriate dissemination and use of biometric data is not in the scope of this International Standard, but may be subject to national regulation.

ISO/IEC 19785-2 specifies the procedures for the operation of the Biometric Registration Authority (which is identified on the webpage www.iso.org/mara). ISO/IEC 19785-3 specifies several patron formats for which ISO/IEC JTC 1 SC 37 is the CBEFF patron. ISO/IEC 19785-4 specifies several Security Block formats for which ISO/IEC JTC 1 SC 37 is the CBEFF patron.

The Network-Based Media Processing framework defines the interfaces including both data formats and

APIs among the entities connected through the digital networks for media processing. Users can access

and configure their operations remotely for efficient intelligent processing. It describes and manages

workflows to be applied to the media data. This process includes uploading of media data to the network,

instantiation of the media processing tasks, and configuration of the tasks. The framework enables

dynamic creation of media processing pipelines, access of processed media data and metadata in realtime

or in a deferred way. The media and metadata formats used between the Media Source, Workflow

Manager and Media Processing Entities in a media processing pipeline are also within the scope.

The ISO/IEC 21122 standard, also known under the term JPEG XS, specifies a low-latency, lightweight image compression system offering compression tools for high-speed, ultra-low online compression of images and image sequences.

This document contains the reference software of JPEG XS. Its purpose is to act as a guideline for implementations and as a reference for conformance testing. It has been successfully compiled and tested on Linux and WindowsTM operating systems at the time of writing.

This International Standard specifies the security requirements for a cryptographic module utilised within a security system protecting sensitive information in computer and telecommunication systems. This International Standard defines four security levels for cryptographic modules to provide for a wide spectrum of data sensitivity (e.g. low value administrative data, million dollar funds transfers, life protecting data, personal identity information, and sensitive information used by government) and a diversity of application environments (e.g. a guarded facility, an office, removable media, and a completely unprotected location). This International Standard specifies four security levels for each of 11 requirement areas with each security level increasing security over the preceding level.

This International Standard specifies security requirements specified intended to maintain the security provided by a cryptographic module and compliance to this International Standard is not sufficient to ensure that a particular module is secure or that the security provided by the module is sufficient and acceptable to the owner of the information that is being protected.

This document provides guidance based on ISO/IEC 27002:2013 applied to process control systems used by the energy utility industry for controlling and monitoring the production or generation, transmission, storage and distribution of electric power, gas, oil and heat, and for the control of associated supporting processes. This includes in particular the following:

— central and distributed process control, monitoring and automation technology as well as information systems used for their operation, such as programming and parameterization devices;

— digital controllers and automation components such as control and field devices or Programmable Logic Controllers (PLCs), including digital sensor and actuator elements;

— all further supporting information systems used in the process control domain, e.g. for supplementary data visualization tasks and for controlling, monitoring, data archiving, historian logging, reporting and documentation purposes;

— communication technology used in the process control domain, e.g. networks, telemetry, telecontrol applications and remote control technology;

— Advanced Metering Infrastructure (AMI) components, e.g. smart meters;

— measurement devices, e.g. for emission values;

— digital protection and safety systems, e.g. protection relays, safety PLCs, emergency governor mechanisms;

— energy management systems, e.g. of Distributed Energy Resources (DER), electric charging infrastructures, in private households, residential buildings or industrial customer installations;

— distributed components of smart grid environments, e.g. in energy grids, in private households, residential buildings or industrial customer installations;

— all software, firmware and applications installed on above-mentioned systems, e.g. DMS (Distribution Management System) applications or OMS (Outage Management System);

This part of ISO/IEC 19795:

⎯ establishes general principles for testing the performance of biometrics systems in terms of error rates and throughput rates for purposes including measurement of performance, prediction of performance, comparison of performance, and verifying compliance with specified performance requirements;

⎯ specifies performance metrics for biometric systems;

⎯ specifies requirements on the recording of test data and reporting of test results; and

⎯ specifies requirements on test protocols in order to:

⎯ reduce bias due to inappropriate data collection or analytic procedures;

⎯ help achieve the best estimate of field performance for the expended effort;

⎯ improve understanding of the limits of applicability of the test results.

This part of ISO/IEC 19795 is applicable to empirical performance testing of biometric systems and algorithms through analysis of the comparison scores and decisions output by the system, without requiring detailed knowledge of the system’s algorithms or of the underlying distribution of biometric characteristics in the population of interest.

Not within the scope of this part of ISO/IEC 19795 is the measurement of error and throughput rates for people deliberately trying to subvert the intended operation of the biometric system (e.g., by presentation attacks).
