FIG. 1 schematically shows a search system (also known as VISS) using the optical fiber of the present invention. The optical fiber 1 is a parallel system that bidirectionally communicates an analog optical signal 2 and a digital optical signal 3 using an optical fiber line 1, and an authentication server 4 that performs individual authentication using the analog optical signal 2, A control conversion circuit 5 for passing a digital optical signal 3 paired with the analog optical signal 2 authenticated by the authentication server 4, and a search condition input and a search result output based on the passed digital optical signal 3. A data server 6 is provided for providing both search operations to the search server and storing images and sounds. In addition, the authentication server 4 is equipped with a general security device 4a, and the data server 6 can also search on the general Internet via the World Wide Web (WWW). FIG. 4 is an explanatory diagram of the authentication server 4, in which at least one of an individual's voice, palm, and retina is individually authenticated by a recognition device 41, and personal information collected by the recognition device 41 is used as an analog signal. The authentication processing is performed by transmitting the authentication result to the authentication server 14 via the control conversion circuit 5. The authentication result is returned to the control conversion circuit 5, and if the authentication is correct, the search is performed. The additional information based on the unique information obtained by the individual recognition can be reflected in the search condition and the search result of the data server 6. That is, when the search condition is input, a condition that is likely to be selected based on the unique condition is used. Toka to first to be presented, and if the search result is a large amount, it is possible to be processed into easy-to-use information by adding the specific conditions.

The conditions for individual authentication are assured that the individual's voice, palm, and retina are secure. It may be a password using a keyboard. Figure 3 illustrates the hospice and bottleneck selection search.

The data server 6 for hospice and wellness consists of a menu process 6 1 1 that presents menus classified into large items according to purpose, and a registration process 6 1 2 that registers individual data according to the menu. The voice of the individual to be used is used as a search key with the analog optical signal as the search key. Those that fall under are sorted out. The data is displayed by the individual questioner using the display means 63 shown in Fig. 2 while the individual who selects the service item display 6 13 is combined with the corresponding data into a stereoscopic image of a doctor with a virtual reality feeling. Is displayed.

In addition, for the data registered and transmitted by the search system VISS 614, an electronic medical record is created at the first time, and after the second time personal authentication is performed, the desired data is automatically analyzed from the personal information and the menu is created. Are sorted out, categorized as monthly medical data, and output to various devices. This data has been automatically transferred to healthcare providers. It can analyze the information and provide counseling and health management information, and can refer to hospitals etc. if there is a medical condition (process 615). In addition, they can formulate hospitalization plans and transportation plans, and make reservations and applications for them (Step 6 16). Next, an explanatory diagram of the stock price search system based on FIG.

After completing personal authentication as shown in Fig. 1, the end user at home or company enters the kanji name, abbreviation, or code of the stock of interest (step 101), and as shown in Fig. The data is transmitted by the optical fiber one-line search system VISS (step 102), and the search results (step 103) according to the search key are sent back to the end user in large quantities at high speed by a digital line. This is detailed data as provided in a conventional securities company, and can be provided to each home via a single optical fiber line. Next, while the data provided in step 103 is historical data, step 104 displays future forecasts based on analysis of past stock price movement data. Waveform or similar to the transition graphic of By comparing the waveforms from the past accumulated data in an analogous manner, the future trends are read, predicted and provided to end users. In the same way, analogy analysis can be used to predict trends in exchange rates and to make statistics and forecasts of stock prices in the event of a crash in the past.

Separately, from the input of stock issues in step 101, press information and related articles-business content · industry trends · list of banks and business partners · securities analysts' views and other corporate information can only be collected Instead of using an optical fiber line, it is possible to respond to any question of the end user by the virtual reality president's image (step 105). That is, the end user's question is transmitted as an audio signal as an analog signal and analyzed as it is, and from the received analog signal, an appropriate audio answer is selected based on the content analysis of the question and returned to the end user. By displaying the president's image corresponding to the audio in a CG composition and displaying it, it is possible to provide a sense of virtual reality that allows a question-and-answer session with the real president.

Based on this information, the end user can buy and sell stocks and execute limit reservations (step 106). For orders that have been traded, the end user who has been authenticated by using VISS can be used. The source is notified and (Step 1
