Proposal
• Some added and revised texts are proposed to be
included in the RFID HIS resolution of the GSC-11
meeting.
– GSC-11 recognized:
• There are many new standardization topics on networked B2B, B2C
and B2B2C RFID applications; and
• A focus group is taken into account at ITU-T to create a common
work place for all RFID matters.
– GSC-11 considered:
• Close cooperation with SDOs is required due to different and limited
work scopes.
GSC: Standardization Advancing Global Communications
Proposal
– GSC-11 resolved:
• To encourage harmonized standards development; and
• To make a formal procedure of ITU-T with PSOs and SDOs to set
up close cooperation for and develop harmonized and globally
compatible RFID-related standards.

RFID developed in B2B
GSC: Standardization Advancing Global Communications
RFID evolved in B2C
GSC: Standardization Advancing Global Communications
New challenges in B2C RFID
• Existing RFID-related standards cover only B2B RFID.
• Characteristics of B2B and B2C
B2C
B2B
Goal
• Content distribution
• Work flow automation
Service user
• Human
• Business logic
Service terminal
• Cell phones
• PDA, PC, POS, etc.
Contents
• information, voice, music,
game, video, etc.
• Contents for the five
senses of human
• Business-related
Information
Network
• Expensive wireless
network based
• Low cost wire network
based
User property
• Dynamic
• Static

Standardization topics (1/6)
• Rationale: new service requirements require more
standards and some extensions.
• Service requirements analysis
– Existing ARP (Application Requirements Profile) is for B2B
applications.
– B2C and B2B2C have different requirements.
• Reader, tag and smartcard integration
– B2C terminal needs reader, tag and smartcard features all
together.
• Application data protocol extension
– ISO/IEC 15961 might need some extensions to support tagbased B2C RFID applications.

Standardization topics (2/6)
• ID code identification
– A variety of code schemes and even private codes exist.
– How to distinguish them and how to process a code need to be
defined.
• ID code representation
– A processed ID code is just a bit string.
– How to denote ID needs to be defined.
• Ex.: 1.2.3, 1:2:3, 123, etc.
• Ex.: 0xCF.0x8E.0x83.0xEB, 0317.0216.0203.0353, 3482223595,
etc.

Standardization topics (3/6)
• ID code naming
– “1.2.3.4” is IPv4 address or ID?
– Name is much better than numeric code.
– A unique name is needed. (ex. urn:ip:v4:1.2.3.4)
• Application data encoding
– ISO/IEC 15961 & 15962 provides a framework of tag data
encoding.
– EPCglobal provides its tag data format.
– But, application user data encoding is not specified yet.
• One-code, multi-uses requirement
– A single code must be associated with a single physical object
and multiple logical objects.
GSC: Standardization Advancing Global Communications
Standardization topics (4/6)
• Code resolution protocol
– A resolution infrastructure needs to be established.
– Candidate protocols: DNS, IRIS, X.500, LDAP, etc.
• ENUM extension, in case of using DNS,
– “e.164.arpa” is a special domain for E.164 resolution into a URI.
– Another special domain will be helpful for a code resolution into
a URI.
• Directory interoperability
– There may be many different directory infra. (ex. EPC directory
via ONS, Japan’s UID directory, IRIS directory, Korea’s ODS
directory, etc.)
– Directory interoperability needs to be considered.

Standardization topics (5/6)
• Reader management protocol
– JTC 1/SC 31 and EPCglobal are working on this, but focusing on
B2B-purposes readers.
– B2C models have different requirements for B2C-purposes
reader systems.
• Service gateway architecture
– Service broker may be exploited for B2C to give subscribers
value-added services.
– Architecture and relevant protocols need to be considered.
GSC: Standardization Advancing Global Communications
Standardization topics (6/6)
• Password acquisition protocol
– kill and lock features require a proper password.
• Privacy control architecture and protocols
– Private information may be leaked easily.
– A privacy control architecture may be exploited to manage
access privileges to private information.
– Relevant protocols may be followed.
• Adult verification
– Even boys and girls below 10 are using cell phones. ID
applications can make they access to adult contents very easily.
GSC: Standardization Advancing Global Communications
Relevant SDOs (1/3)
• ITU-T
– Covers application and network aspects of identification
including RFID.
• ISO/IEC JTC 1/SC 31/WG 4
– Covers the scope between tags and an RFID application system
via multiple RFID readers except for application and network
aspects.
– WG 4/SG 1 deals with application interface protocol and data
encoding.
– WG 4/SG 3 deals with air interface protocols.
GSC: Standardization Advancing Global Communications
Relevant SDOs (2/3)
• EPCglobal
– Has more extended work scopes including application and
network aspects than ISO/IEC JTC 1/SC 31/WG 4. But it focuses
on B2B applications.
• ISO/IEC JTC 1/SC 17
– Deals with smartcard issues, for examples, air interface
protocols, data encoding, etc.
• ISO/IEC JTC 1/SC 27
– Deals with security techniques.
• IETF
– Deals with directory-related issues such as LDAP, DNS, etc.
GSC: Standardization Advancing Global Communications
Relevant SDOs (3/3)
• OMA
– Deals with content negotiation for cell phone environment
GSC: Standardization Advancing Global Communications
Conclusion and Proposal (1/3)
• Relevant SDOs have different work scopes.
• There are many prospective additions and extensions to
existing RFID-related standards. Due to limited work
scopes,
– Some of them correspond to ITU-T’s prospective work items;
– Some of them correspond to cooperation work items with other
SDOs; and
– Some of them are likely to be other SDOs’ work items.
• Therefore, close cooperation is required to develop
harmonized and globally compatible RFID-related
standards.
GSC: Standardization Advancing Global Communications
Conclusion and Proposal (2/3)
• A leading formal action of ITU-T is required to set up
close cooperation with PSOs and SDOs and develop
harmonized and globally compatible RFID-related
standards.
• So this contribution proposes following added and
revised texts:
– GSC-11 recognized:
• There are many new standardization topics on networked B2B, B2C
and B2B2C RFID applications; and
• A focus group is taken into account at ITU-T to create a common
work place for all RFID matters.
– GSC-11 considered:
• Close cooperation with SDOs is required due to different and limited
work scopes.
GSC: Standardization Advancing Global Communications
Conclusion and Proposal (3/3)
– GSC-11 resolved:
• To encourage harmonized standards development; and
• To make a leading formal procedure of ITU-T to set up close
cooperation with PSOs and SDOs and develop harmonized and
globally compatible RFID-related standards.
