Secure LMS for Private Recorded Lectures

I'm looking for a Learning Management System (LMS) that can deliver recorded lectures to students with complete privacy. The system should be secure enough to prevent any form of recording or downloading by any source.

Key Features:
- Customized user ID and Password for student access
- Computer Based platform (not accessible on mobile or web)
- Implementing DRM (Digital Rights Management) to prevent unauthorized distribution
- No right-click and screenshot blocking to ensure content is not captured

Ideal Skills and Experience:
- Extensive experience in developing secure LMS
- Proficient in implementing DRM and other security measures
- Strong understanding of creating customized user access systems
- Able to develop computer-based, non-mobile accessible systems
