Abstract

A system and method for controlling the use of addresses by using address computation techniques is described. A system comprising alias address creation software generates multiple alias addresses representing a single real address of a particular recipient. Each alias address is computed from data representing a prospective sender and a recipient. A sender is provided with an alias address by a recipient for communicating back to said recipient. Messages sent by a sender, employing alias addresses are analysed to a forwarding server which validates each alias address and checks it against a blocking list. Messages which pass these checks are directed to the recipient'"'"'s real address registered with said forwarding server.

Claims

1. A computer-implemented method for automatic submission of an alias address via a web form comprising the steps of:

detecting, on a recipient computer, the web form requesting input of an address;

generating an alias address, by a software on the recipient'"'"'s computer, based on at least the domain part of the URL of said web form, an encoded string and a recipient'"'"'s identifier;

detecting and recognizing, in the web form, an input field where said address is to be entered; and

filling out said input field with said generated alias address.
