Explosion of User Generated Content

Envision a world where almost all user generated content is uploaded for archival and publishing

–All raw footage shot & pictures taken

–Will dwarf all text

Publishing driven from the net

–On the fly transcoding, mixing, etc.

Minimal required metadata

–Simple description

Strongly encourage additional metadata

–Very easy and intuitive to add

–Activity, participants, etc.

Privacy Issues Associated With Search

Users may wish to limit exposure of video’s existence– Richer metadata exposes more

Today can create rich access control per publishing site– Within site search unfettered

– Limits visibility to Internet-based search

Can & should video search be enhanced to enforce access rights?

Identity For Search?

Perhaps video provides opportunity–Universal “soft” identification of user

•Implies universal directory

Enforced by search engines–Add visibility to access restricted content

Optional extension to existing search–If identification available then access protected exposed
