<P>PROBLEM TO BE SOLVED: To solve the problem that it is necessary for a user to preliminarily register a telephone number input for confirming the telephone number in authentication, and that it is necessary to depress a numerical string with 11 digits in a portable telephone even though only numerical keys are needed, and that it is necessary to finally perform time-consuming button operations across the several number of times even through it is simple in a conventional technology. <P>SOLUTION: A code log-in system having two main feature points is provided. A first feature point is performing authentication processing without registering the telephone number of a portable terminal as a physical device for authentication by generating and using an AV code signal equivalent to a password for authentication each time the transmission request of content is made. A second feature point is outputting and displaying the AV code signal for authentication as, for example, a two-dimensional bar code or the like on the screen of an AV device. <P>COPYRIGHT: (C)2009,JPO&INPIT |
