@Goyal, Mayank If you are using the REST API and using the URL in the request body then the requirement is to use a URL of an image that is available to public internet. In the case of storage container too, you need to ensure the image URL is available from internet. The request will then use this URL or image data to extract text and results are temporarily encrypted and stored in Azure Storage. The results are then available with the read result API. You can lookup data privacy page for azure computer vision to know more about how the data is used.
