FAQs

QUESTIONS PUBLISHERS ASK.

Crux DRM is a digital rights management layer for publishers that combines content protection, authentication, licensing, access control and secure reading.

Crux eBook Reader is the secure reading experience used to access protected digital books while supporting features such as search, zoom, bookmarks, highlights, notes and reading history.

The Crux model is designed to integrate with an existing publisher website rather than requiring the publisher to abandon its existing platform.

Your website communicates with the Crux DRM API to create or manage licenses and authorize secure reading.

The intended workflow allows the publisher's existing payment process to confirm a purchase before the website invokes the Crux DRM API.

Licenses define the access granted to a customer, including applicable validity and access rules.

Yes. The core Crux model is designed around selling digital books through the publisher's own website and connecting the purchase to secure access.

The licensing model can support defined rental periods such as 30, 90 or 180 days.

Subscription access is one of the digital business models described for Crux licensing.

Crux is designed to support controlled access for schools, colleges, students, teachers, departments and other institutions.

Device control is included as a DRM capability. The exact device policy depends on the implementation and licensing rules.

Usage control can be configured to control permitted actions such as printing and copying, subject to the supported implementation.

License management includes license revocation as part of the intended API and access-control workflow.

The API-oriented architecture is intended to integrate with publisher websites and custom-built commerce systems.

The integration model is designed to work with a publisher's existing customer system; the exact authentication flow is determined during integration.

Yes. API integration is a core part of the Crux DRM model.

Format support should be confirmed for the specific Crux deployment and content workflow. The product concept includes digital books such as PDF/EPUB.

Multiple-device reading can be governed by device authorization and the publisher's license rules.

Yes. Institutional access for educational institutions is a defined use case.

Integration time depends on the publisher's website, authentication, commerce flow, catalogue and the required licensing model. It should be estimated after reviewing the existing system.

The Crux approach is compatible with retaining the publisher's existing website and commerce environment, allowing digital delivery to be added alongside existing products subject to integration design.

Free preview workflows can be designed as part of the publisher's digital catalogue and access model. The exact implementation should be confirmed during integration.

No. The central model is that Crux integrates with the publisher's existing website and commerce system as the DRM and secure-reading layer.

The Crux positioning is built around the publisher retaining its own customer relationship rather than handing the customer over to a closed marketplace.

Analytics are part of the Crux platform concept, including license, reader, device, order and reading activity views where implemented.
