### Security and compliance
> Confidently handle millions of files every day with built-in tools for secure upload, storage, processing, and delivery.


#### [Signed uploads](http://uploadcare.com/docs/uploading-files/#signed-uploads)
> Control which users can upload files and how long that access is available via generated signature tokens.
