This accumulation table is prepared as, for example, an HTML document or an XML (extensible Markup Language) document, and is provided to the user by an HTTP server or the like executed in the storage server 60. It can be browsed as a display as shown in FIG. In the column of each issue ID, a link to an electronic receipt corresponding to the issue ID is described, and by instructing the link, the corresponding electronic receipt can be browsed.

This accumulation table is used, for example, when preparing a tax return, and is used in the above-described calculation processing 68 in FIG. For example, if the subject and item are matched with the tax return, the accumulated value can be used as it is as the numerical value of the tax return.

When a legal effect is recognized on the electronic receipt, the above-mentioned electronic receipt may be read and recorded on a recording medium, and may be attached to the tax return as electronic data. This can contribute to simplification. Furthermore, if the tax return itself can be submitted as electronic data, by posting the cumulative value in the cumulative table in a predetermined form, it can contribute to further simplification of the procedure. .

In this electronic commerce system, in addition to the user himself / herself viewing the electronic receipt as described above, another user who is permitted to view the electronic receipt can also view the electronic receipt.
For example, when the above-mentioned tax return is prepared, after submitting the tax return, the electronic receipt relating to the tax return can be viewed by a tax accountant or a competent authority.

To this end, the browsing terminal 70 executes an authentication process for specifying the browsing requester, and
In, it is determined whether or not the browsing requester has the authority, and the access restriction process is executed. In the browsing processing unit 64, information (browsing ID) for identifying a person permitted to browse is registered together with authentication information such as a password.

A person who intends to browse operates the browsing terminal 70, inputs a browsing ID, a password, etc., specifies a browsing target (for example, an electronic receipt specified by the issuing ID), and Request browsing. The browsing processing unit 64 checks the password or the like for the browsing ID and determines whether the browsing requester has authority. When the browsing requester has the authority, the browsing processing unit 64 permits browsing of the specified browsing target. On the other hand, if the browsing requester does not have authority, the browsing processing unit 64 refuses browsing. By performing such access restriction, it is possible to permit only those who are permitted to view the electronic receipt. In addition, the access restriction may be performed, for example, on a subject-by-subject basis or on a time basis, in addition to the user unit.

For example, when viewing a tax return after submitting the tax return, the taxpayer or the like is permitted to view the electronic receipt of the previous year relating to the submitted tax return, but is not allowed to view the electronic receipt of the current year. Can restrict access such as not permitting browsing.

Specifically, for example, the above-mentioned electronic receipt is
According to the date, store it in the directory for each issue year,
By restricting access by a tax accountant or the like on a directory basis, access can be restricted on a yearly basis.

As described above, in the electronic commerce system of this embodiment, the electronic receipt issued by the notarization server 50 is stored in the storage server 60 managed by a different entity from the notarization server 50. The possibility that the issued electronic receipt is altered can be reduced, and the reliability of the electronic receipt can be improved.

Conventionally, in order to confirm the validity of a document signed by a notary institution, it was necessary to confirm with the notary institution. However, in the electronic commerce system of this embodiment, the validity of an electronic receipt is It is only necessary to check with the storage server 60 according to the issue ID in the electronic receipt in order to check the electronic receipt. Since the electronic receipt is stored in the storage server 60 together with the issue ID according to the user ID. ,
The validity of the electronic receipt can be checked relatively easily. In addition, as described above, by managing the electronic receipt for each user and for each subject, it is possible to contribute to simplification of processing such as creation of an accumulated value.

In the above description, an example of a tax return has been described. However, the present invention can be applied to the case where a document is created or audited using an electronic receipt. It can also be applied to auditing of the settlement of accounts of the business of the above. Further, the operating entity of the storage server 60 may be an office or the like that prepares tax or audit documents using an electronic receipt of a certified public accountant, which can contribute to the efficiency of document creation.
