Single Sign-On (SSO) Implementation on Video Streaming Services

    1. Introduction
    2. How to include the SSO function in the video?

1. Introduction

The Video Streaming Service (VSS) has been launched for about a year which provides a video on demand platform for HKU users to host and share their videos.  All videos are stored in the VSS server which are open to public without any restrictions. However, there may be situations where this open access is not desirable and need to restrict the sharing to HKU users or a particular group of HKU users only.

We are pleased to announce the introduction of an optional function, Single Sign-On (SSO), on the VSS.   With SSO, users can apply access control on their videos to restrict access by an individual or a group of people with valid HKU Portal accounts.  If users have already logged onto HKU Portal, they can view the videos without further login.   As this is an optional function, videos not applying SSO will remain open for public access.

2. How to include the SSO function in the video?

Normally, a web page containing the URL of the video would be developed so that viewers can access the video via the web page.  To use the SSO function, video owners are required to include simple JavaScript codes on the SSO function under the web page.  The codes will invoke a customized video player, developed by ITS based on the Adobe Open Source Media Framework, for enabling the checking of user credentials before playing the video.  Please note that departmental website hosting the web page for the videos must be registered in the Central Authentication Service (CAS) database for enabling the HKU Portal login. For details and sample of the JavaScript codes, please refer to the User Guide.
