I've been assigned a web project that deals with shipping goods between two parties. I am unsure what a secure database scheme (if any) would be for storing the recipient's postal address and whether or not there are data privacy laws in regards to how these addresses should be stored? Both the recipient and the sender will require access to the address in the system.
Or unlike passwords, would it be okay to leave them as plaintext? Amazon is an established company, and when you log in to your profile, they would show you your address. This implies that Amazon stores them either in plaintext or in a decryptable state.
