Highlight of Current Activities (1)

• What is an ID scheme?
• ID (identifier) is used to uniquely identify an
  entity
• Definition An unambiguous name, in a given
  naming context (see ITU-T Terms and Definitions
  Database)
• ID scheme is a method of assigning numbers to
  entities
• Current activities in SDOs
• Various ID schemes according to the specific
  purposes and applications
• Phone number, International Standard Book Number
  (ISBN), Universal Product Code (in barcode), IdM
  in ITU-T, EPC global Unique Item Identifier
• ITU-T is developing a couple of new ID schemes
  for applications and services using tag-based
  identification
• xCode and uCode for multimedia services using
  tag-based identification
• ISO/IEC has many ID schemes to identify physical
  objects in RFID context
• ISO/IEC 15459, 15963, 7816-5

Highlight of Current Activities (2)

• Why do we need a global ID system?
• Too many ID schemes in the world, but
• Most of them are not interoperable in global
  context
• For example, EPC global Unique Item Identifiers
  are unique in EPC network context ,not in global
  context
• Can an almighty ID scheme cover every tag-based
  identification applications?
• This almighty ID scheme should be long enough
• Does an application which has only 10 entities to
  identify need 128 or more bits long identifier?
• Designing a new ID scheme for its own purpose is
  better
• We need a global ID system which enables us to
  use any ID scheme
• OID (Object Identifier, ITU-T X.660 series
  ISO/IEC 9834-x) is key for this global ID system

Strategic Direction

• How to identify an entity in global context
• An ID with OID can uniquely identify entities in
  global context
• ID is unique only in a specific context
• OID can be used to identify this specific context
• ID with OID to uniquely identify an entity
  already used in this purpose in some area
• OID is an International Standards (ITU-T X.660
  series ISO/IEC 9834-x)
• Propose to use OID in order to enable globally
  interoperable ID system
• OID should be used to specify a specific context
• International Standards and Recommendations
  related to ID should describe how to specify a
  specific context using an OID
• Which OID should be used
• How to write OID and ID into the data carriers
  such as RFID tags

5
Challenges

• OID is used to identify context (ID scheme) in
  some of SCM (Supply Chain Management) area, but
  not generally
• For example, ISO/IEC 15962 defines how to encode
  OID and ID into RFID tags
• EPC global Unique Item Identifiers do not have
  OIDs
• Significance of ID is highlighted by RFID and
  SCM, but RFID is just small part of tag-based
  identification applications
• De facto SDOs are focusing on their on
  application area
• They are not considering the global context
  (identify an entity in global context)
• To re-use current existing ID schemes, which has
  no OID, in global context, we need to assign OIDs
  to them
• By whom and How?

6
Next Steps/Actions

• ITU-T and ISO/IEC should collaborate to expand
  usage of OID for a global ID system
• Identify problems of current existing ID schemes
  which are being used in global context
• Use OID to enable a globally interoperable ID
  system
• Recommend other SDOs to design their ID schemes
  to be identified in global context using OID

7
Proposed Resolution

• Proposed revision on RESOLUTION GSC-12/03
• Add the following in Resolves section
• to encourage the ITU-T, PSOs, other relevant
  standards bodies and fora /consotia to
  collaborate in order to promote the use of OID to
  enable a globally interperable ID system

• Problem of current ID system
• It is O.K even if ID 10101 is used in both
  context
• But in global context

Supplemental Slides (2)

• Example of global ID system based on OID
• It is O.K even if ID 10101 is used in global
  context because it has different OID

Global Context
OID 1.2 ID 11010
OID 1.1 ID 11010
OID 1.1 ID 10010
OID 1.2 ID 10010
OID 1.1 ID 10101
OID 1.2 ID 10101
