FIG. 4 shows a data format when information is transmitted from the information providing device 1 to the user terminal device 2. As shown in the figure, an information header representing the beginning of the information is arranged at the head, and subsequently, an information identification ID for identifying the information is arranged. A number is regularly assigned to this information identification ID according to the classification of the data.

Next, as file information, date and time of data creation, data type, data classification, data characteristics and data amount are arranged so that a user can easily search. That is, the user appropriately selects a predetermined one of the creation date and time of the data, the type of the data, the classification of the data, the characteristics of the data or the data amount,
By designating, predetermined information can be selected from many information.

Subsequent to the file information, substantial information to be provided to the user is arranged, and finally, an information end identifier indicating the end of the information is arranged.

Next, in the above information retrieval system,
An operation in which the user accesses the information providing device 1 via the user terminal device 2 and retrieves predetermined information will be described with reference to the flowchart of FIG.

First, in step 101, the user performs line connection processing. That is, when the user operates the operation device 37 of the user terminal device 2 to instruct access to the information providing device 1, the CPU 32 controls the communication interface unit 36 to execute the line connection process. When receiving a command from the CPU 32, the communication interface unit 36 reads the telephone number of the information providing device 1 stored in the storage device 40 in advance, and starts the call operation for the telephone number. When the information providing device 1 responds to this calling operation, the process proceeds to step 102, and the CPU 32 executes the user ID transmission process. That is, the CPU 32 uses the user / user information in the call setup message to
The D and password are transmitted to the information providing device 1 via the communication interface unit 36.

When the information providing apparatus 1 receives the supply of the user ID via the communication interface unit 18, the information providing apparatus 1 executes the user authentication process in step 103.
That is, the CPU 13 searches the user management information in the storage device 12 based on the received user ID and password, and determines whether the user with this user ID is a legitimate user.

In the case of access from an authorized user, the CPU 13 transmits the data of the initial menu screen to the user terminal device 2 via the communication interface section 18. When the user terminal device 2 receives this initial menu screen data via the communication interface unit 36, the user terminal device 2 displays the data via the display circuit 38.
Output to 9 and display. That is, the initial menu screen reception process of step 104 and the initial menu screen display process of step 105 are executed. As a result, for example, FIG.
As shown in, the initial menu screen is displayed on the display device 39.

Next, in step 106, the CPU 32
Determines whether or not a history reference command has been input, and if not, proceeds to step 107,
Perform information retrieval processing. That is, the user operates the operation device 3
When the user operates 7 to instruct to search for shopping information from the menu of FIG. 6, for example, the CPU 32 notifies the information providing apparatus 1 that the search for shopping information has been selected. Upon receiving this notification, the CPU 13 of the information providing device 1 transmits the menu of information on shopping stored in the storage device 11 to the user terminal device 2. Upon receiving the supply of this information (step 108), the user terminal device 2 displays it on the display device 39 (step 109). Thereby, for example, a list of products desired to be purchased is displayed.

When the user selects, for example, clothes from this display, the selection signal is transmitted to the information providing device 1. When the CPU 13 of the information providing device 1 receives the input of the clothing selection command, it reads the clothing selection menu data from the storage device 11 and transmits it to the user terminal device 2. When the user terminal device 2 receives the supply of the data of the clothing menu, the user terminal device 2 displays the data on the display device 39. As a result, more detailed selection items such as women's clothing, men's clothing, children's clothing, etc. are displayed on the display device 39. The user further selects a predetermined item from these.

When supplying such information to the user terminal device 2, the information providing device 1 encrypts the data by the encryption circuit 16 and transmits it. User terminal device 2
In this, the encrypted data is decrypted by the decryption circuit 3
5 is decoded and displayed on the display device 39.

As described above, steps 107 to 1
The process of 10 is repeatedly executed until the desired product is selected.

When the desired product is finally selected, the user operates the operation device 37 to give an instruction to end the selection of the product. When the input of this command is determined in step 110, the process proceeds to step 111, and the CPU 32 of the user terminal device 2 executes the history update process of the information identification ID.

Details of the history update process of the information identification ID are shown in the flowchart of FIG.

First, the CPU 32, in step 201,
It is determined whether or not a command for designating the directory of the finally selected product has been input. That is, when the user wants to register the information of the product which he / she has just accessed in his / her own classification (directory), he / she can register the directory. In this case, the user operates the operation device 37 to give an instruction to specify a directory.

When the designation of the directory is input, the CPU 32 proceeds to step 202 to read the already registered directory from the storage device 40 and display it on the display device 39. As a result, for example, as shown in FIG.
9 is displayed. In the display example of FIG. 8, D1 to D
Four directories of 4 are displayed.

In step 203, the user determines whether or not there is a directory corresponding to the product just selected from this directory. In the case where the directory that corresponds to the information that has been accessed does not exist in the already registered (displayed) directories, the process proceeds to step 204, and the user operates the operating device 37 to add a new one. Enter the name of the directory to be used. Upon receiving the input of this name, the CPU 32 registers the name as a new directory name in the storage device 40 in step 205.

Then, the process returns to step 202 again and the registered directory is displayed. As a result, the directory added in step 204 is displayed on the display device 39.

Then, if a directory corresponding to the accessed information exists from the displayed directories, the process proceeds to step 206 and the operating device 37 is operated to specify the directory. CPU
32 causes the storage device 40 to register the identification ID corresponding to the information finally selected in step 207, corresponding to the directory designated in step 206. In addition, at this time, the CPU 32 searches whether or not the same identification ID is already registered in the storage device 40, and if it is registered, increments the number of receptions by one. Then, the number of times of reception is also registered in the storage device 40.

When it is determined in step 201 that it is not necessary to specify the directory, the processes of steps 202 to 206 are skipped and the process of step 207 is immediately executed.

In this way, the identification ID of information that has been accessed in the past and the number of times it has been received are appropriately registered in the storage device 40 as a history of the information identification ID in association with the directory.

As described above, after the history update process of the information identification ID is performed, the process proceeds to step 112 of FIG. 5 to determine whether or not the end of shopping is instructed, and the end is not instructed. In, the process returns to step 104, the initial menu screen is displayed, and the same processing is repeatedly executed.

On the other hand, when terminating the access, the user operates the operating device 37 and instructs the CPU 32 to that effect. At this time, the CPU 32 proceeds to step 113, controls the communication interface unit 36, releases the connection with the information providing device 1, and ends the process.

If it is determined in step 103 that the access is not from a legitimate user, the process immediately proceeds to step 113, where disconnection and release processing is executed.

As described above, the user can use the information providing device 1
To access information that has been accessed even once in the past, in the initial menu screen display state shown in FIG.
Select the item for history reference. At this time, the process proceeds from step 106 of FIG. 5 to step 114, and the history reference process is executed. Details of this history reference processing are shown in the flowchart of FIG.

That is, the CPU 32 of the user terminal device 2
When a history reference command is input from the operation device 37, in step 301, history information display processing is executed.
As a result, the information identification I stored in the storage device 40
The history (list) of D is read and displayed on the display device 39 via the display circuit 38. At this time, for example, in FIG.
As shown in, the directories registered in the processing shown in the flowchart of FIG. 7 are displayed first in descending order of access frequency (number of times of reception). The directories D1 to D4 shown in FIG. 10 are set to D1 to D4 as shown in FIG.
The directories are displayed in this order because the access frequencies thereafter are D3, D2, D4, and D1.

In step 201 of FIG. 7, when the user does not specify the directory, the display here is the type of data, the classification of data, the characteristics of data and the data described as the file information of FIG. A history is displayed for each quantity.

Next, in step 302 of FIG. 9, the user specifies information. That is, for example, as shown in FIG. 10, in the state where the directory to which the information that the user has accessed in the past belongs is displayed on the display device 39, the user operates the directory to be accessed. The device 37 is operated to select. CP
When a predetermined directory is selected, the U 32 reads a list of information belonging to the directory from the storage device 40 and displays it on the display device 39.

For example, when the directory D3 is selected in the state shown in FIG. 10, as shown in FIG. 11, information belonging to the directory D3 and having been accessed in the past is displayed. Even in this case,
Each information is displayed in order from the one with the highest access frequency.

In the embodiment of FIG. 11, the information B, C and A are displayed as the information belonging to the directory D3 and which has been accessed in the past.
Information B has the highest access frequency, followed by information C and information A.
Therefore, the information B, the information C, and the information A are displayed in this order as shown in FIG. These pieces of information are registered in the storage device 40 in the order of information A, information B, and information C in the order of registration. However, if the information frequencies are the same, for example, as shown in FIG. Displayed in chronological order.

The user repeats the same processing in step 302 until the information to be accessed is displayed on the display device 39. When the information is finally designated, the CPU 32 proceeds to step 303 and searches the storage device 40 for the information identification ID of the designated information. That is, as described above, step 20 in FIG.
In FIG. 7, since the history of the information identification ID of the information accessed in the past is registered in the storage device 40, this information identification ID is searched. Then, in step 304, this information identification ID is transmitted to the information providing device 1.

When receiving the information identification ID, the information providing apparatus 1 reads the information corresponding to the information identification ID from the storage device 11 and transmits it to the user terminal device 2. The CPU 32 of the user terminal device 2 receives the information transmitted from the information providing device 1 in step 305, and displays it on the display device 39 in step 306.

In this way, for information that has been accessed in the past, when the information is designated, an operation for receiving the information is automatically performed. Therefore, it is possible to promptly receive desired information.

Next, in step 307, it is determined whether or not the end of the history reference processing is instructed. If the end instruction is not input, the process returns to step 301 and the above-described operation is repeatedly executed.

When the end of the history reference process is instructed by operating the operation device 37, the CPU 32 ends the history reference process. After that, the process returns to step 111 of FIG. 5, and the history update process of the information identification ID is executed.

As described above, when re-accessing information that has been accessed in the past, it is possible to automatically receive the information only by designating the information from the list of the information. Therefore, it becomes convenient, for example, when ordering a product that is regularly required in online shopping.

In the above embodiments, the operation has been described by taking online shopping as an example, but the present invention can also be applied to the case where video information such as a movie or a game is provided.
