Description

    The present invention relates to an electronic receipt issuing system used in a state in which a purchaser and a seller make direct sales.

Traditionally, when buyers and sellers make direct purchases and purchases, the seller has issued paper receipts created by the register etc., but this is inconvenient for financial processing and storage management of paper receipts. In order to solve this problem, some electronically issued receipts.
In other words, when a buyer checks out at a cash register, an electronic receipt at the time of purchase represented by the computer installed at the cash register, including purchase date / time, purchased item, purchased quantity, price per unit item, and total purchase price. Data is stored in the purchase information database of the service center via the Internet. A system is configured in which a purchaser can access the purchase information database of a service center using user information given to each purchaser and check his / her purchase information (for example, Patent Document 1).

  On the other hand, the purchaser purchases electronic receipt data at the time of purchase, which is expressed by purchase date and time, purchased item, purchased quantity, price per unit item, total purchase price, etc. Electronic receipt data sent to a mobile phone of a person and the electronic receipt data sent to the mobile phone was stored in a storage system called a household account book server and used an electronic receipt issuing system used for financial accounting. (For example, patent document 2).

JP 2002-157314 A JP 2004-021607 A

  In the above-mentioned patent document 1, data from a computer (electronic receipt issuing machine side) connected to a cash register is stored in a service center via the Internet. On the buyer side, as electronic receipt data, This is only the contents described on the sheet created at the cash register, and there is still a possibility of taking time for processing, as in the storage and tabulation thereof.

  On the other hand, in Patent Document 2, it is true that the electronic receipt data is left on the household account book server via a mobile phone (electronic receipt receiving machine), but the cash register (electronic receipt issuing machine) side does not. There is no description that the electronic receipt data is stored, and the existence of the electronic receipt data is not clear.

  In other words, in any content described in any patent document, it is difficult to match the electronic receipt data between the electronic receipt issuing machine side and the electronic receipt receiving side, and a system that ensures tampering etc. with respect to the receipt. It was not.

  An object of the present invention is to construct a highly reliable electronic receipt issuing system that is difficult to falsify after issuance when creating electronic receipt data.

〔Constitution〕
The characteristic configuration of the first invention is an electronic receipt issuing system operated by an entity different from the user used in a state in which a user of a buyer and a seller directly buys and sells,
An electronic receipt issuing means that issues electronic receipt data and has a storage means, an anti-falsification means that provides an anti-falsification function to the electronic receipt data, and an electronic receipt data that is provided with the anti-falsification function And a portable electronic receipt receiving means provided with a storage means, and the electronic receipt receiving means is provided corresponding to each of the electronic receipt receiving means for storing the electronic receipt data received by the electronic receipt receiving means, Electronic receipt storage means having a falsification preventing function sent to the electronic receipt receiving means by the electronic receipt issuing means, which is separate from the storage means held by the electronic receipt receiving means. The electronic receipt issuing means provided corresponding to the electronic receipt issuing means separate from the storage means held by the electronic receipt issuing means. For example,
Tamper-proof function of the tamper proof means, there the time stamp certifying transaction conclusion date and function to be added as data, to a function of attaching an electronic signature based on electronic certificate,
The operating entity that operates the electronic receipt issuing system is a cooperative or a service providing organization, and the cooperative or service providing organization establishes the use standard as a usage standard for users who use the system. The user is limited to satisfying the membership standards of the association or service providing organization,
The operating entity operating the electronic receipt issuing system gives the electronic signature of the operating entity to give the electronic receipt issued by the electronic receipt issuing means the falsification preventing function of the falsification preventing means. The effects are as follows.

[Action]
When the sale is established, the electronic receipt data is provided with a falsification preventing function such as a sales date and a sales place by the falsification preventing means. The electronic receipt data provided with the falsification preventing function is transmitted from the electronic receipt issuing means such as a computer and stored in the issuing electronic receipt storing means via a wired / wireless transmission means, for example. The information is transmitted to the portable electronic receipt receiving means, such as a mobile phone or a smart phone, which the purchaser has, by the wired / wireless transmission means. The electronic receipt data transmitted to the electronic receipt receiving means is stored in the receiving electronic receipt storing means.

As described above, the electronic receipt data is stored in both the issuing electronic receipt storing means and the receiving electronic receipt storing means with an electronic signature attached together with the sales date and time and the sales location.
In this way, it is possible to create a situation that is difficult to be tampered with by being stored in both electronic receipt storage means.
In addition, since the electronic receipt data has a function for preventing falsification, it is further difficult to falsify.
Furthermore, when doubt arises in the electronic receipt, it can be confirmed by matching the data held in both electronic receipt storage means.

  Therefore, a simple electronic receipt issuance system that does not use paper receipts can be constructed, non-tampering is ensured, and the origin, issue destination, issue date and time of electronic receipts are accurately recorded, and the originality We have been able to provide a system with a high guarantee effect that guarantees

〔Constitution〕
In the present invention, the following characteristic configuration is that the falsification preventing function of the falsification preventing means provides a time stamp certifying the date and time when the sale is completed as a data and an electronic signature based on the electronic certificate. The effect is as follows.

[Function and effect]
In other words, it is possible to attach an electronic signature based on a time stamp and electronic certificate, which ensures non-tampering, clarifying when, who and where the transaction was exchanged, and the authenticity of the electronic receipt It became possible to prove clearly.

〔Constitution〕
In the present invention, the following characteristic configuration is that an operating entity operating an electronic receipt issuing system gives an operating entity electronic signature to the electronic receipt, and the operation and effect thereof are as follows.

[Function and effect]
If there is an entity that operates the electronic receipt issuing system, the reliability of the electronic receipt can be increased by further adding a signature guaranteed by the entity to the electronic receipt to which the falsification preventing function is given.

〔Constitution〕
In the present invention, the following feature configuration is that the operating entity that operates the electronic receipt issuing system is a predetermined organization, and the organization determines the submission of a predetermined usage document as a usage standard for a user who uses the system. The effects are as follows.

[Function and effect]
If the operating entity is a specified organization, the organization will submit the specified usage documents such as a copy of the registry or a resident's card to the user side so that the users can be selected and the electronic receipt system can be secured. The proof of electronic receipts can be improved by improving the performance and grasping the entire system by the organization.
