`DETAILED DESCRIPTION
`
`Basis of the Present Disclosure
`
`[0010]
`
`provided
`
`Underlying Knowledge Forming
`Inarestaurant, when a dish with a
`suppressed allergen ingredient is
`to a customer who is allergic
`to this ingredient, it is necessary to
`4
`
`provide
`
`P1030866
`
`

`

`this dish with the suppressed ingredient correctly
`dish with the suppressed allergen ingredient is, for example,
`or a dish
`a reduced amountof
`
`to this customer. Herein, the
`no
`a dish including
`
`including
`allergen ingredient
`where, whena dish is ordered
`Hereinafter, in a case
`a dish is
`for this customer such that no
`
`prepared
`amountof
`
`allergen ingredient.
`a customer having
`
`by
`
`allergy,
`or a reduced
`
`allergen ingredient
`is included in the dish, such a dish is referred to as
`allergen ingredient
`allergen-controlled dish. When a dish which is not controlled in terms of
`at the same table, if this dish is
`allergens is ordered by another customer
`sitting
`to the customer who has ordered an
`
`an
`
`allergen-controlled dish,
`erroneously provided
`this may cause a tremendous adverse effect on the health of the customer who
`has ordered the allergen-controlled dish. Thus, it is necessary to avoid such a
`situation.
`
`[0011]
`
`eating
`
`Inthe
`
`disclosed in PTL 1 described above, in a case where the
`technique
`rule includes a rule about
`dishes
`the
`
`allergic
`including
`allergic ingredients,
`are excluded from the menu information of the recommended dishes.
`
`are removed
`
`ingredients
`[0012] However, PTL 1 merely discloses that allergic ingredients
`from menu information and the resultant menu information is presented, and PTL
`1 discloses nothing about providing the dish selected by the customer via the
`menu information to the customer's seat. Therefore, in the technique disclosed in
`are
`PTL 1, there is a
`possibility that a wrong dish, from which allergic ingredients
`not removed, is incorrectly provided
`to the customer's seat. Thus, in the
`technique
`disclosed in PTL 1, there is a
`a dish from
`that the customer
`possibility
`are not removed, which may
`which
`
`ingests
`cause the customer to have
`
`allergic ingredients
`a serious health problem.
`Furthermore, since the information on
`allergic ingredients is sensitive
`[0013]
`to a
`information, it is necessary to prevent the information from being provided
`third party without the permission of the user.
`screen that enables it to
`PTL 2 discloses an order input

`Therefore, there is a
`erroneous

`
`possibility
`
`In
`
`by
`that a seat and a dish item are

`incorrectly

`[0015] As described above, in the technique disclosed in PTL 2, the seat and the
`dish item are

`to occur when the restaurant is crowded. Furthermore, the order
`input
`disclosed in PTL 2 includes various kinds of information and objects in addition to
`as shown in Fig. 38 of PTL 2. This
`the seat
`position image and the dish images
`results in an increase in the possibility that an error occurs when inputting is
`on the order input
`screen disclosed in PTL 2. Thus, the technique
`performed
`to those in the technique disclosed in PTL
`disclosed in PTL 2 has similar problems

`
`[0016]
`
`To solve the
`
`problems

`
`to the present aspect,
`[0021] According
`processes in which the user orders a
`dish, the ordered-dish information indicating
`the dish selected by the user from the personalized
`menu is automatically
`associated with the seat of the user without a manual
`operation. Therefore, for
`of users sit at the same table and each

`
`Furthermore, in the present aspect, since the allergy information is not

`transmitted to the second server, it is possible
`to prevent the allergy information
`to the restaurant. Furthermore, in the

`system mainly
`A first apparatus group includes an information terminal 100 such as a
`the user. A
`owned
`is installed in the
`
`smartphone
`by
`matching application
`information terminal 100. The matching application is an
`application for selecting
`or
`a
`or service suitable for a user based on the user's
`
`recommending
`product
`personal information. The personal information referred to here broadly includes
`or
`non-public information about an individual. For example, the personal
`public
`an
`a name, a date of birth,
`information includes at least one of the following:
`an owned movable
`an annual income,
`estate information,
`property/real
`information as to
`or the like, genetic information, allergy
`physical
`height/weight
`information, medical information as to a medical
`record or the like,
`history/medical
`amount information as to the number of steps/calories burned,
`meal
`activity
`history
`information, vital sign information as to heartbeat/blood pressure or the like,
`purchaseinformation via stores/EC sites or the like, word information as to words
`used in searching via Web search engine/Al speaker, information as
`text/video/audio transmitted or received via mail/SNS, and movement
`history
`or the like. The information terminal 100 is capable of connecting
`information,
`via a mobile communication network called 4G or 5G
`the Internet, for
`example,
`and via a mobile
`
`address,
`
`to
`
`basestation 400.

`The second apparatus group includes
`personal information related to a
`personal information server that stores
`user such that the personal information is decrypted and distributed at a
`plurality of
`locations. For example, the first server 200 manages personal information such
`that the personal information related to the user is fragmented, encrypted, and
`stored in a
`plurality of storage apparatuses located on the cloud. This ensures
`that high security is achieved and leakage of the personal information is
`prevented. Furthermore, the first server 200 has a function of
`data in responseto an

`Furthermore, the first server 200 has a function of
`securely sharing
`personal
`a user with a company permitted by the user. Thatis, the
