Introduction

My name is Leonard Rosenthol and I am a Senior Principal Architect at Adobe.   At Adobe, I am the architect for PDF and our recent Content Authenticity Initiative (CAI, https://contentauthenticity.org/). In this role, the TDM work is extremely important to us since we believe that much of the content to be “mined” exists in PDF format and I offer my expertise in this area to help the committee understand the technical and practical implications of the work.

I also represent Adobe at various standards bodies including the W3C, ISO, ETSI, ICC and others.  In my standardization role, there are three committees that I am involved with that are extremely relevant to this work.  First, I am the chairman of ISO TC 171/SC 2 which is where PDF itself (and its subsets) are standardized as ISO 32000.   Secondly, I am the editor for the XMP specification (ISO 16684), which is the standard for embedded metadata in assets (images, videos, audio, etc.).  I believe that XMP can play an important role in the work that this group is to accomplish.   Finally, I chair the Technical Working Group of the newly formed Coalition for Content Provenance and Authenticity (C2PA, https://c2pa.org) and I think that issues of provenance and authenticity play strongly into the ability to assert rights and licenses.

Looking forward to today’s meeting.
