Introduction
Purpose and Justification:
— Non-discriminative applications: As many subjects as possible are expected to be able to access a
biometric system. A large number of the overall public is smaller groups, such as families or
accompanied persons, and they will not be discriminated against.
— High throughput: One main objective of the use of biometric access control systems for biometric
subjects as well as for operators is the speed of the process and the prevention of queuing times.
This would include the applicability of processes to as many persons as possible.
— Increasing automation: Automation can limit time spent on recurrent processes and can decrease
the need for (e.g. human and financial) resources. As automation is increasing also in daily life
applications, e.g. access to leisure facilities, applications in smart cities etc., the approach should be
inclusive and cover most user groups. Such an inclusion of smaller groups into automated access
control processes would be the expectation of the public, as such groups are a major fraction of all
parties in real life.
— Focus sharpening: Human interaction and staff allocation could in such an automated system focus
on more difficult and more complex cases. That way, as easier cases are processed automatically,
the more complex cases themselves can be treated faster, and they do not slow down the overall
process.
— Prevention of child trafficking: When designing biometric access systems for small groups,
measures should be considered to prevent child trafficking e.g. by providing a group internal
linkage. This could massively improve the security level as of today.
Benefit for Stakeholders include:
— usage harmonization,
— extension of the target user group compared to current biometric access control technology,
— interoperability in workflow and data formats,
— establishment of usable biometric group access in several application environments,
— facilitation of throughput of biometric processes used for access control, and
— integration of biometric technology into security technology.

5 Group access control processes and technologies
5.1 Architecture
5.1.1 General
The access point architecture shall support authentication of small groups of persons using biometric
technology and additional token or documentation, e.g. mobile phone or tickets. Therefore, a system
needs to have at least two elements: one for capturing biometric data and one for checking the
authorization to access e.g. by an additional token or documentation.
