title: Which Azure products for public users to upload their private data?
body: <p>I'm building an iPhone app that collects user's physiology data (e.g., timing of heart beats), which will be about 5-50mb per session. I'd like to allow users to upload these data with their ID and comments to Azure, but I'm not quite sure which products to use. I was looking at Azure Blob storage but it does not have write permission to public. Thanks for your help in advance.</p>
