theme : Privacy increases usability
title?
outline :
Describe workflow in existing payment systems
- Cash
- authentication at ATM
- transaction authenticated by the cash
- worries : counterfeit bills, wrong currency, etc.
- refunds
- CC authentication
- online vs offline
- extended verification
- credential theft
"this reversal of authentication vs shoping slows shopping"
- worse because exposing yourself to a merchant
- can choose not to use a particular ATM
- 40 million stolen at target
- refunds, annoys banks
- swipe vs chip vs NFC
- Bitcoin
- external application
- p2p not prowser friendly
- 5+ or 10 minute transactions mean designing new shopping carts
- minning suck0rs,
- massive transaction fees : blockchain.info
- hits you 2-3 times
- conversion sucks
- DDoS : wired article?
Taler overview
copy from proposals?
- bank, mint
- wallet
- merchant
- auditor
Taler payment process from customers prospective
- similar to cash
- ATM
- merchant
- contract
- digitally signed is better than paper receipt
- failure modes
- insufficient funds
- restoring from backups causes double spending
- mint gives proof
- restoring from backups can lose coins
- mint not accepted by merchant
- F
- change
- refunds
vs CC
vs Cash
Wallet provides isolation
Near copy from EXIST protosal?
- Limits user risk
- Nearly eliminates risk for merchant and mint
- lower transaction fees
- Reserves simplify things
Denomination choice
- Anonymity refresh protocol
- Withdraw automates like ATMs
Browser extension
- RESTful vs Bitcoin, OpenCoin, etc.
- Retrying RESTful transactions always works
- minimizing dialog
- see & pay ??
- TBB integration
- Needed anyways
- Other browser integration?
- Is it wise? Ok if not worried about anonymity Taler is still better
- Is tor2web worse?
- W3C
Autopay? pat payment recognision?
- dangerous?
- high charges
- good for funny money
NFC
