Patent number: 8464352Abstract: Protection is provided to prevent a computer user from unintentionally giving away sensitive data (e.g., security credentials, credit card number, PINs, personal data, or bank account number) to an illegitimate or unintended entity by means of a client application capable of communicating the sensitive data across a network to other computer users. To provide the protection, user input is monitored to detect a user entry of the sensitive data into the client application for communication to other users. When such an entry occurs, action is taken to reduce the likelihood of an unintentional giveaway of the sensitive data or to reduce the effects of an unintentional giveaway.Type: GrantFiled: August 8, 2011Date of Patent: June 11, 2013Assignee: Bright Sun TechnologiesInventor: Christopher Toomey

Patent number: 7730137Abstract: The volume of outgoing electronic messages from a given entity may be restricted by preventing the messages, such as spam, from being sent. Messages may be restricted, for example, by serializing outgoing messages using a mutual-exclusion locking technique or by using a ticket-based system. Serialization may occur, for example, at a web level in web-based implementations. In one system, a limited-use ticket is generated that allows an entity to send one or more electronic messages, and the ticket is provided to the entity. A request is received from the entity to send an electronic message, and the request is associated with the ticket and the electronic message. After receiving the request, a determination is made as to whether the ticket is valid and, if the ticket is determined to be valid, the electronic message is approved for sending.Type: GrantFiled: December 22, 2003Date of Patent: June 1, 2010Assignee: AOL Inc.Inventor: Christopher Toomey

Publication number: 20060080730Abstract: The invention provides an affiliation within a single sign-on system, which affiliation comprises a group of service providers that have chosen to act as a single entity on a network from the point of view of authentication, federation, and authorization. This type of entity is used to implement functionality within a portal site, such as the Yahoo (see http://www.yahoo.com) portal with a Travelocity (see http://www.travelocity.com/) travel section that acts as part of Yahoo and not as part of Travelocity. In the preferred embodiment, there is an owner of the affiliation that is responsible for maintaining a list that shows which service providers are members of the affiliation, as well as any control structure or meta-data associated with the affiliation. Each affiliation must have an identifier that is unique within the single sign-on system in which the affiliation is defined. User actions associated with the affiliation apply to all entities within the affiliation.Type: ApplicationFiled: October 12, 2004Publication date: April 13, 2006Inventors: Conor Cahill, Christopher Toomey, Andrew Feng

Publication number: 20050216582Abstract: A system and method for determining in a global network the user network authentication status as the user goes from site to site within the network is provided. Additionally, the system and method provides for transparent or implicit multi-site logon functionality, including automatic introduction from one site to the other using a baseline authentication agency (102). The system and method provides an architecture for a core global network (100) (referred to herein as NET) that incorporates some or all of the following features and components: a set of baseline authentication agencies responsible for the core global network (NET) services, such as login and user-selected service-provider lookup; a shared NET domain and associated DNS records (106) used for cookie (110) sharing, login routing, and the like; and a collection of partner sites (108) accessible via the NET.Type: ApplicationFiled: July 2, 2003Publication date: September 29, 2005Inventors: Christopher Toomey, Conor Cahill

Publication number: 20050108551Abstract: A method and apparatus for fine-grained, trust-based rate limiting of network requests distinguishes trusted network traffic from untrusted network traffic at the granularity of an individual user/machine combination, so that network traffic policing measures are readily implemented against untrusted and potentially hostile traffic without compromising service to trusted users. A server establishes a user/client pair as trusted by issuing a trust token to the client when successfully authenticating to the server for the first time. Subsequently, the client provides the trust token at login. At the server, rate policies apportion bandwidth according to type of traffic: network requests that include a valid trust token are granted highest priority. Rate policies further specify bandwidth restrictions imposed for untrusted network traffic.Type: ApplicationFiled: January 15, 2004Publication date: May 19, 2005Inventor: Christopher Toomey
