Transcript of Coins in Cloud Drives Can Use OAuth for Micropayments and Resource Metering Alike
.
Micropayments and Clouds
.Micropayments are.....
.... small payments like all pay-per-* services (-view, -read, -access)
• today micropayment systems implement strict protocols like those inbanking, credit cards, etc.
• main differences between payment and micropayment:
1. transactions have a fixed cost, which can exceed the value of micropayment itself2. payment of 1 yen is (much) less critical than 5000 yen3. micropayments are similar in nature to resource metering (in clouds)

Visual Taxonomy
• different levels ofcritical
• metering of cloudresources is a kind ofpay-per-*technology
.Cloud Coin.....
.
.. is an ecoin stored in acloud drive.

Solutions and Cloud Applications.Solutions : Micropayment Bundles..
.
Service Provider should be able to accumulate micropayments (ex: 1transaction per 100 micropaments)
.Solutions : Decouple Payment from Clearing..
.
Procedures for micropayment bundling vs clearing payments aredecoupled
.Solutions : Differentiate Security Levels..
.Micropayments can enjoy lower security while clearing remains traditionally strict
• Why clouds? Clouds today are very poorly distributed, noframeworks for distirbuted management of resources, distributed accounting,etc.

Solution : Visual Form• note that thenewmicropay-ment(EU-CD-CP) isoutside ofthecriticalarea
• security level= degreeof accu-mulation,decided bySP

The Actual Cloud Coin (JSON file)
• cloud coins aresecure --OAuth protocol
• OAuth is a 3-partyprotocol, flexibleaccess and securitycontrol -- better thanbanking protocols
• coins themselves aresmall JSON filesin own cloud drive(GDrive, Dropbox)
.Cloud Coin is a JSON file.....
.
... which can be accessed by SP/CP using OAuthtokens.
• most cloud services today use OAuth• OAuth works with pairs of tokens, different pairs forowner versus accessor of a file

Solution : Micropayments.Solution......accumulate payments, clear regularly
• accumulation degree is up to SP(tradeoff with transaction cost)
• profile users to avoid fraud --higher accumulation for reliable users
• note: coins are created by CPs, so SPmay have to support several populartypes

Solution : Cloud Resources.Solution..
.
...use coins as a crude meteringinstrument
• crude means that precision can belower
• no money involved, lowertransaction cost when clearningaccumulated amounts
• metering has several forms: quotas,accounting, billing, monitoring
