Track and Trace
• Challenges in complete track and trace system:• Involves multiple parties• Huge number of log entries• Response time requirement• Counterfeit of labels/tags

RFID and Blockchain technology to help investigate counterfeiting problem in supply chain
• Goal of the platform• To ensure product integrity• Get insight on the sources of the counterfeit items
• Strength• Low-cost RFID tag can serve as the unique ID for the item• Data storing on Blockchain is immutable, and the blockchain
infrastructure can be “shared” by multiple parties, i.e. brand-owners, manufacturers, chain stores, etc.

• Traditional permissioned blockchain data are transparent to all users – for traceabilityEveryone (in the network) sees. Authorized parties can add to itOnce a transaction record is confirmed, nobody can change it
• Commons ways to keep data private in Hyperledger Fabric:• Channels with different memberships• Stores encrypted data in blockchain• Access control in smart contract• Private data collections
Different ways of protecting privacy
