In cybersecurity, 'captions' refer to the on-screen text that displays spoken dialogue or relevant sounds in videos, webinars, or live streams. While primarily designed for accessibility - assisting users who are deaf or hard of hearing - captions also play a role in content security and compliance. For example, accurate captions can help organizations meet legal accessibility requirements, avoid data leaks by ensuring sensitive spoken information is not exposed in public captions, and support secure communication in multilingual environments. Captions may be automatically generated or manually created, and their management can involve encryption or access controls to prevent unauthorized distribution.
