1. Authentication of product items in the supply chain: Role of the chain of custody
4/5-October-2017

2. There is safety to be found in the implementation of the full suite of GS1 standards – capitalise on operations visibility as opposed to covert markings

3. e-Pedigree as a pre-requisite for authentication
Different approaches to traceability
Traceability models:
Honesty models – e.g. Fair Trade
strictly non-real time, e-pedigree refer to shipments and volumes of product and is subject to verification by means of physical audits
Batch-and-order models – e.g. most of pharmaceutical and FMCG tracking
real time and/or non-real time, e-pedigree based on batch and volumes of product and, in some instances, can be hard, but mostly not
Item instance model – e.g. the SCC-system operating in the South African cotton industry
strictly real time, inherently forensically hard
Use GS1 set of standards:
Link internal stock codes to GS1 codes
Mark using EPC
Track using EPCIS

4. Capture history per item handling event
Trigger: Relate output items to input items through all value-add process steps
A one-to-many situation
where: I = item, i = item instance number, n = the number of items produced under the specific batch/WO/Lot

5. Capture history per item handling event
Trigger: Each new event inherits the past and adds an additional line

6. Capture history per item handling event
Trigger: Create a single traceability audit trail across the supply chain
Single version of the truth A B C D

7. Capture history per item handling event
Trigger: Item handling events tie up with purchase orders and sales orders
Purchase Contract
Sales Contract
Purchase order
Sales order
Receive
Transformation
Out
Dispatch In

8. An example: The Sustainable Cotton Cluster - system

9. Tracking all supply-chains in the cotton value chain
The cotton value chain supported by the SCC-system
Cotton Pilot: achievements since 2013
200% increase in SA cotton production
35% Increase in local cotton beneficiation
about 500 jobs created
1300 small farmers established
1600 people received BCI training
11 integrated supply chain programmes (product lines) created
ZAR 2,5 billion integrated supply chain value throughput

10. Authenticating against a trusted body of evidence

11. A forensically hard body of evidence
Summary of authentication triggers
S-GTIN – A SGTIN number can be issued once only per item instance
Input-Transformation-Output – Reference-ability between product items and raw material items (by instance level ID) and manufacturing process
Accumulated history – shows a known history of item handling events from origin – built in real time - cannot be changed or added after the event – absence of such history a risk trigger
Traceability audit trail creation – this audit trail follows the supply chain – created through machine-to-machine communications – automatically structured as organisations trade – no human intervention in this procedure
Contracts-orders-items – link items visibly to legitimate orders and contracts and role players – information structured accordingly throughout the supply chain
