Published by: 2017-02-01 / 2017-02-01 / 34 pages

ISO/IEC 2382-37:2017 establishes a systematic description of the concepts in the field of biometrics pertaining to recognition of human beings and reconciles variant terms in use in pre-existing biometric standards against the preferred terms, thereby clarifying the use of terms in this field.

Excluded from the scope of this document are concepts (represented by terms) from information technology, pattern recognition, biology, mathematics, etc. Biometrics uses such fields of knowledge as a basis.

In principle, mode specific terms are outside of scope of this document.

Words that are bolded are defined in this document. Words that are not bolded are understood in their natural language sense. The authority for natural language use of terms in this document is the Concise Oxford English Dictionary, Thumb Index Edition (tenth edition, revised, 2002). Words used in their natural language sense are considered out-of-scope for further definition in this document.

– User Description (UD): a set of descriptions which may contain static and dynamic information about the user, including some other data like the history of the user’s interactions, preferences, security settings regarding these information, etc.

– Context Description (CD): a set of descriptions of the environmental situation in which the user operates, e.g., user’s device in use, physical position, environmental variables (temperature, humidity, sound level, etc.), security settings regarding these inform ation, etc.

– Service Description (SD): a set of descriptions containing information (including security settings) about the service (or a set of sub-services), that is offered to the end-user application, e.g. video on demand, maps, etc.

– Recommendation Description (RD): a set of descriptions containing information about recommended items, provided when a customer requests a service in a certain context and in a certain environment. RD may include 1) the recommended content, 2) information extracted from UD, CD, SD, 3) additional logical relations among UD/CD/SD (or their subsets) and 4) metadata from UD/CD/SD.

ISO/IEC 21000-22:2016 specifies User Description, Context Description, Service Description and Recommendation Description. Description Managers, Recommendation Engine and Application are outside of the scope of this document.
