Appl. No.:

10/404631

Inventors:

Peter L. Katsikas - Honolulu HI, US

International Classification:

H04L 29/06

US Classification:

Abstract:

A system for eliminating unauthorized email sent to a user on a network analyzes the sender address of incoming email and determines whether it is to be rejected by returning a standard “no such user” error code or accepted depending upon executing processing rules and analyzing managed lists of authorized senders. This provides an advantage over existing anti-spam filtering systems by intercepting unauthorized email before it reaches an existing email server or client. The system rejects all email unless authorized by using a standard “no such user” error code, and by redirecting the unauthorized email back to the sender or to a sender evaluation site. An ASL module captures authorized sender addresses from the user's outgoing email and other sources in order to update “authorized senders” lists. The system may employ a WBM procedure that notifies senders of rejected email to go to a separate website and register as valid senders after passing an interaction test that precludes automatic registration by a mechanical program. A destination proxy email address procedure allows subscribers to use temporary proxy addresses for receiving email expected from unknown sources and instantiates senders as authorized upon receiving the expected email to the proxy addresses.

Abstract:

A system for eliminating unauthorized email sent to a user on a network employs an email-receiving server connected between the network and the user's email client for receiving email addressed to the user and rejecting those in which the sender address does not match any of sender addresses maintained on an “authorized senders” list (ASL list). The ASL lists are maintained by an ASL manager in an ASL database operable with a spam processor module. A redirector module rejects the email if, upon sending a request for validation to the spam processor module, the sender's address does not match any authorized sender address on the ASL list. Email rejected by the redirector module is redirected to a web-based messaging (WBM) module which sends a message to the sender to confirm that the sender is a legitimate sender of email to the intended recipient. If the sender logs on to confirm their status, the WBM module executes an interaction procedure which can only be performed by a human, in order to ensure that the confirmation procedure is not performed by a mechanical program. The ASL manager maintains the ASL lists based upon sender address data collected from various sources and analyses of various email usage factors, including sent email, received email, contact lists maintained by the user, user preference inputs, third party programs, etc.

International Classification:

H04M 3/00

US Classification:

37926501, 4554141, 705 141

Abstract:

A call-ordering system and method enables convenient ordering in a call center transaction from a mobile phone. User profiles with identification data and a mobile phone number are matched to advertiser offers. Text messages are sent to the mobile phone numbers for matched users with a direct inward dialed (DID) number for response. Upon receiving an incoming call to the DID number from a responding user, an OfferRouter uses the caller and DID numbers to retrieve identification data for the user and offer data for the advertiser offer. The incoming call is then routed to a call center associated with the advertiser offer and the retrieved data are pushed to the call center's terminal system for pre-filling a transaction record for the offered item. The system may also be operated in tandem with a hotel guest registration system to register traveler profiles, the hotel's purchase management system to bill call center transactions to a guest's hotel bill, and the hotel's networked TV system to give guests an option to respond to an offer by using signals sent from the TV remote control unit to complete a transaction.

A destination proxy email address procedure allows subscribers to use temporary proxy addresses for receiving email expected from unknown sources and instantiates senders as authorized upon receiving the expected email to the proxy addresses. The unauthorized-email rejection component can be readily configured as a hardware or software appliance used in tandem with a conventional email server, email gateway, or firewall to an intranet, or as a software extension to an existing firewall system.
