Abstract: A bar code is added to a printed medium having one or more images visible to the human eye. The bar code is printed with ink invisible to the human eye. The bar code as printed on the printed medium with ink invisible to the human eye is then detected, such as by a computing device like a mobile phone-type device. Information relating to the images on the printed medium is decoded from the bar code and transmitted to an electronic service. In return, electronically encoded information relating to the images on the printed medium is received from the electronic service and displayed.

Abstract: An apparatus for easily shooting an invisible image (such as an invisible two-dimensional bar code) latent on an object. The operation of the apparatus is made intuitive and simple and may be incorporated into cameras peripheral to computers and mobile telephones. A novel framing and focusing system is also disclosed.

Abstract: A communication apparatus for connecting each of a plurality of information processing apparatuses to a communication line provided by an ISP (Internet Service Provider) by wirelessly communicating with each of the plurality of information processing apparatuses, the communication apparatus including a subscriber terminal determination unit for determining whether or not each of the plurality of information processing apparatuses is managed by a subscriber to the ISP who has been authorized based on a contract with the ISP to connect to the communication line by installing the communication apparatus, and a communication unit for wirelessly communicating with each of the plurality of information processing apparatuses giving a higher priority to a subscriber terminal that is an information processing apparatus managed by a subscriber than to a non-subscriber terminal that is an information processing apparatus not being a subscriber terminal.

Abstract: In an information processing system, a mobile phone obtains a setting program which makes security settings for ensuring security of communication by performing authentication with a communication destination on an unsecured communication link, from a registration server through a secure, first communication link; an information processing device executes the setting program obtained from the mobile phone to make security settings, communicates with a relay server through an unsecured, second communication link; the registration server receives access from the mobile phone through the first communication link, authenticates a user, and sends the setting program to the mobile phone; the relay server authenticates an information processing device in response to a connection request from the information processing device, makes security settings, and relays access from the information processing device to a communication network through the second communication link.

Abstract: In a case where a secondary use of a communication line which is provided as a communication service is permitted, an appropriate communication charge to be charged to each user is computed in order to promote the use of the communication line. There is provided a communication relay system providing communication service which connects a communication device to an existing communication network.
