US Patent 11658822 Dynamic cross origin resource control

Example methods and system for providing content are disclosed. One or more cryptographic keys may be generated. At least a portion of the one or more cryptographic keys may be used to generate a token associated with a user interface service. The token may indicate a valid origin domain. The token may be provided to a user device, which may use the token to request content from a content service. The content service may authorize the request based on a comparison of the valid origin domain and an origin identifier associated with the request.
