biodiversity virtual e-laboratory (biovel): athentication & authorisation

Biodiversity Virtual e-Laboratory:

Authentication & AuthorizationProject OverviewBioVeL is an e-laboratory that supports research on biodiversity using large amounts of data from cross-disciplinary sources.

Why Authentication & Authorization?

• Accounting– Who is using which service

• Resource Limitation– e.g. only one metagenomics workflow execution

at a time

Authentication: User login

• Standard login• Google• Facebook• Twitter• Generic OpenID

Authentication: Web Service

• OAuth– Dot.com support

• Google, Facebook, LinkedIn etc.

• Widely used • Higher likelihood to find

experienced developer

OAuth: Secured Workflow

• Slice of secured metagenomics workflow:

Open Source Solution
