As AI-generated and edited media become convincing, it is harder to know what is real. Provenance standards attach tamper-evident information to a file recording how it was created and changed, and some AI tools mark their output, so viewers and platforms can check an item's origin.
This helps flag synthetic or manipulated media and credit genuine work, supporting trust in what people see. It only helps where the information is attached and preserved, and determined fakers can strip or avoid it, so it is one layer among several rather than a complete answer, but it gives a practical way to carry origin information with media.
