If you publish your original work in a digital form, you can use technological measures to prevent unlawful uses of your material. These are commonly known as the Digital Rights Management Systems (DRMs).
DRMs cover a range of technologies, such as:
- systems to identify owners' rights and give information on licensing - eg to enable collecting societies to accurately pay royalties
- copy protection systems to prevent unauthorised copying - eg to prevent consumers from transferring films stored on DVD to a computer hard drive
Taking infringement action
If you sell protected copies of your work, you may have the right to take action against a person who gets round or removes the technological measures. Criminal offences may also apply to those who deal in the means to get round technological measures.
Copy protection and copyright exceptions
Although it may be legitimate for right holders to use these tools to prevent copyright infringement, they can also prevent permitted activities that fall under copyright exceptions.
If you feel that your use falls under one of the exceptions, you may request a workaround to the protection measures from the right holder. If they do not provide an effective workaround, you may issue a 'notice of complaint' to the Secretary of State.
GOV.UK explains in details the technological protection measures complaints process.
