Microsoft already provides such a solution, which has been widely
deployed as part of IE for Windows. As a developer, you can use
their free tool "Weft" to create the specially encrypted format.
However, it seems to involve too much effort compared with using
image replacements, and hasn't caught on.

For fonts without restrictions on copying, DRM is an unnecessary
pain and a much simpler approach is possible. There are plenty
of such fonts that are perfectly good enough for most purposes.
