Abstract: A subscriber to a universal point of contact service designates a preferred point of contact at which a communication initiator, such as a telephone caller, can contact the subscriber. Such an initiator desiring to contact the subscriber uses the subscriber's email address to establish a communication session with a device associated with the subscriber's preferred point of contact. The subscriber's email address is input to an initiating device, preferably a telephone or facsimile machine, using an entry device capable of entering an email address. A requestor unit, receiving the email address, locates a repository of the subscriber's point of contact information, and requests that information. The repository sends the point of contact information the subscriber has designated as preferred, and the requestor unit uses that information to control a telephone switch to establish a communication session between the initiating device and the subscriber's preferred point of contact device.

Abstract: A creator provides to one or more recipients an electronic note for display at the recipient's device(s). If the creator updates information in the notes the note displayed at each the recipient is automatically updated. The electronic note can have an expiration time associated with it that causes the note to expire automatically at the expiration time. The creator can alter the expiration time after the note has been provided to the recipients. The creator and recipients can exchange and update the note based on an agreement between them. Such an agreement can be embodied in an electronic contract that specifies the information in the electronic note the creator can update.

Abstract: A digital certificate, used in a computing system, includes a distinguished name (DN) field and a common name (CN) field within the DN field. The CN field contains a resource identifier that contains information identifying each of a plurality of resources in the certification path of the digital certificate. The resource identifier can be a hierarchical identifier that specifies an identity of a trusted root resource, and an identity of a resource issuing the digital certificate. The resource identifier can contain identifiers of resources in a certification path between the trusted root resource and the resource issuing the digital certificate. The certification path leads to a trusted source for the computing system.

Abstract: A universal point of contact identifier system calling device facilitates a connection between a caller and a call recipient over a telephone network by communicating with a universal point of contact identifier system server. The calling device includes a keyboard, a display, a circuit to make a telephone call and transmit and receive digital data over the network, a memory unit and a micro-controller to control the functions of the device. The keyboard facilitates the entry of an identifier, e.g., an email address, into the memory unit of the device. After entry of the identifier, the circuit connects the device with the server and transmits the identifier to the server. The server utilizes the identifier to establish a connection over the network between the caller and call recipient.
