An authentication system receives encrypted terminal identification information and terminal identification information, from a transmission terminal, and determines whether decrypted identification information decrypted using a terminal public key obtained by the authentication system matches the terminal identification information received from the transmission terminal.
A transmission system, comprising:
An authentication apparatus for authenticating a transmission terminal before the transmission terminal logs in to a transmission system which includes a management system, the apparatus comprising:
A non-transitory computer readable recording medium which stores a plurality of instructions which, when executed, cause a processor to perform a method of authenticating a transmission terminal before the transmission terminal logs in a transmission system, the method comprising:
A method, implemented by an authentication apparatus, for authenticating a transmission terminal before the transmission terminal logs in a transmission system, the method comprising:

This patent application is based on and claims priority under 35 U.S.C. §119 to Japanese Patent Application Nos. 2010-028781, filed on Feb. 12, 2010, 2010-028783, filed on Feb. 12, 2010, 2011-010032, filed on Jan. 20, 2011, and 2011-010025, filed on Jan. 20, 2011, in the Japanese Patent Office, the entire disclosure of which is hereby incorporated herein by reference.
The present invention generally relates to an apparatus, system, and method of authenticating a terminal that transmits or receives image data and/or voice data to or from another terminal through a network.
With the need for reducing costs or times associated with business trips, more companies are moving towards transmission systems to have teleconference or videoconference among remotely located offices via a communication network. The transmission systems allow transmission of image data or voice data among a plurality of transmission terminals that are remotely located from one another through a communication network such as the Internet to facilitate communication among the plurality of transmission terminals. Before initiating communication among the plurality of transmission terminals, the transmission systems usually authenticate the transmission terminal, for example, by using an authentication system that authenticates the transmission terminal based on identification information received from the transmission terminal.
A more complete appreciation of the disclosure and many of the attendant advantages and features thereof can be readily obtained and understood from the following detailed description with reference to the accompanying drawings, wherein:
FIG. 1 is a schematic block diagram illustrating a transmission system according to an example embodiment of the present invention;
FIG. 2 is an illustration for explaining transmission or reception of data such as image data, voice data, or management data, performed by the transmission system of FIG. 1;
The accompanying drawings are intended to depict example embodiments of the present invention and should not be interpreted to limit the scope thereof. The accompanying drawings are not to be considered as drawn to scale unless explicitly noted.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “includes” and/or “including”, when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
In describing example embodiments shown in the drawings, specific terminology is employed for the sake of clarity. However, the present disclosure is not intended to be limited to the specific terminology so selected and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner.
