Secure copyrights & metadata permanence

The subject of copyright is always high in photographers' minds, especially in light of Orphan Works legislation & rampant image "borrowing" online. Consequently there's an ongoing burning desire for secure metadata that can't be stripped away from images.

Last summer I posted a guest blog entry from Russell Williams called "Why Photoshop doesn't provide secure metadata."  Now Adobe metadata expert Gunar Penikis has posted about the Economics of Trust and Permanent Metadata.  If this subject is of interest to you, you may want to read Gunar's thoughts & the comments that follow.
