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
