User Agent Central ECIS Mechanism

ECIS stands for E-Commerce Interoperability Standard. an interoperability standard between service providers in decentralized web environment

What is ECIS?

  • stands for Electronic Commerce Interoperability Standard
  • it organize multiple e-commerce services with user agent centric mechanisms
  • multiple service providers has their own service mechanism as an island
  • user agent is the central point for multiple connectivities and inter-operations between service providers
  • ECIS make connectivity to each service providers
    • adding standard way to initiate e-commerce service request
    • adding standard way to get response from service provider

Why ECIS is required?

  • no standard method to exchange data between multiple service providers on the web
  • no standard framework to exchange data between multiple service providers on the web
  • because of above absent, current E-Commerce interoperation need complex integration and more resources.
  • when user access shopping service provider(merchant)
    • merchant provide their service on their own way
    • merchant integrate their backend service providers internally
    • no standard to inter-operate/exchange services between multiple providers.
  • a new standard is required
    • de-centralized
    • interoperabilitable
    • between multiple service providers including payment and identity service providers.

Who is Service Provider

  • Banking Web Service
  • Mobile App
  • Identity Web Service
  • Delivery Web Service
  • Currency Exchange Web Service
  • Shopping Web Service

ECIS Sequence Diagram

  1. User(UA) send request payment to Shopping Mall
  2. shopping mall response request-token as XHTML/JSON format
    • the request-token can be signed by merchant
    • the token data can be formatted by ECML or JSON Web Token or others
  3. UA redirect the request-token to Payment Processor
  4. Payment processor response request-token to UA
    • Payment processor need to identity user but they are unable to identity user.
  5. UA redirect the request-token of payment processor to Identity Provider
  6. Identity Provider identify user
    • depends on ID providers
  7. Identity Provider response result as XHTML or JSON format
    • the result can be signed by Identity Provider
  8. UA redirect the result to Payment Processor
  9. Payment Processor verify the result
    • normally XML Signature verification can be used
  10. Payment Processor process payment with User
  11. Payment Processor response payment result
    • the result can be signed by payment processor
    • the formats can be XHTML or JSON
  12. UA redirect the result to Shopping Mall
  13. Shopping Mall verify the result sent from Payment Processor
  14. Shopping Mall deliver product/service to User

Centralized by User Agent

  • between multiple service providers, the mechanism is de-centralized
  • but it is User Central
    • User Agent is the central point organizing decentralized operations

  • Timeouts
    • Shopping Mall can not wait too much time
