Description

Verification system with sonic action payment

The present invention relates to a system for mobile payment, and more particularly to a verification system for sonic mobile payment.

Mobile payment refers to a service that uses a mobile device to make a payment. Consumers can use mobile devices to pay for services or digital and physical goods without the use of cash, checks or credit cards.

At present, there are two main types of mobile payment methods: Bluetooth payment and contactless payment (NFC).

The existing Bluetooth payment is mainly a built-in non-contact chip and RF circuit built in the mobile phone, and the user account payment information is stored in the chip through a special format code. When the user pays, the mobile phone must be pointed at the Bluetooth receiving device, and the user's account information will be transmitted to the Bluetooth receiving device via Bluetooth, and the payment authentication and the transaction can be completed in a few seconds.

However, Bluetooth technology has a disadvantage when it is used as a medium for transmitting messages. It must be paired between the user's mobile phone and the payment device. It takes too long to complete the payment authentication and transaction.

Non-contact payment (NFC) payment methods are often used in physical stores or transportation facilities. Consumers must use a mobile phone equipped with an NFC chip and place the mobile phone in front of the sensor module. Most transactions do not require additional authorization, but some transactions require a password or fingerprint authorization before completing. Payments can be deducted from prepaid or bank accounts or charged to telecommunications charges.

Poorly, the current NFC action payment penetration rate and scope of application are facing serious challenges, because NFC action payments require mobile network operators, trust management service platforms and service providers (probably banks, merchants or Shipment of authorized units) is therefore due to complex infrastructure and complex ecosystem operator architecture, and high-end communications must be installed in handheld communication devices such as cell phones, personal digital assistants (PDAs) or tablets that use NFC mobile payments. The wafer thus derives the problem of excessive cost.

Therefore, how to provide a verification system with fast verification and low cost of action payment should be urgent and needed.

In view of the above-mentioned deficiencies of the prior art, the present invention provides a verification system for sonic mobile payment, which does not require Bluetooth payment to match the pairing, and does not have to use a high-order and expensive communication chip as NFC action payment. Therefore, the technical advantage of the present invention is that the amount of the commodity is converted into the encoded amount data, and the digital signature containing the encoded amount data is transmitted and received between the consumer and the checkout end through an acoustic transmission path. After that, the verification terminal receives the message transmitted by the checkout terminal through the Internet. The digital signature sent and the identification number of the consumer and the amount of the item, the verification end searches for the public key corresponding to the private key of the consumer according to the identification code of the consumer, and decrypts the amount of the digital signature into another item, and then The verification end judges whether the amount of another item is the same as the amount of the item. If the amount of the two items is the same, the verification is successful.

As can be seen from the above, the process of the two-way authentication of the present invention not only ensures that the amount information of the items transmitted between the consumer and the checkout end is not falsified by the hacker, and because the transmission distance of the voice signal is controllable. The sending and receiving distance is very short, so the verification time will be very fast.

Therefore, based on the above object, the present invention provides a verification system for voice action payment, comprising: a checkout end, after the consumer purchases at least one item, the amount of the at least one item is counted to be purchased The amount of the at least one item is encoded by the amount data, and the encoded amount of the data is transmitted to the consumer via an audio transmission path, and the consumer decodes and encrypts the encoded amount data to become a digital sign. a chapter for transmitting the digital signature to the checkout end through the sound wave transmission path; and a verification end receiving the digital signature transmitted by the checkout end and the purchased at least one item through a transmission path The amount of the verification, the verification end decrypts the digital signature into another amount, and further determines whether the other amount is the same as the amount of the item to verify the identity of the consumer.

In the existing mobile payment system, the shortcoming of Bluetooth payment is the pairing matching to complete the payment authentication and transaction. It takes too long, complicated operation, large power consumption and NFC must install high-level communication. The wafer thus derives the problem of excessive cost.

In order to solve the above problems, as shown in FIG. 1 , a block diagram of a verification system 1 for voice action payment is provided, which includes a consumer 11 , a cash register, a computer, a mobile phone, a personal digital assistant (PDA) or a tablet computer. As an example of a checkout terminal 12, the digital verification host is used as a verification terminal 13, and the consumer 11 carries out data by means of a handheld communication device 30 (such as a mobile phone, a personal digital assistant or a tablet computer). Transmission and reception functions.

First, as shown in FIG. 2, the figure shows a process in which the consumer obtains the identification code of the consumer and the private key of the consumer from the verification terminal. In the consumer 11 such as a supermarket, a retail store, a department store, or the like, this type of Before the shopping mall purchases at least one item, the consumer 11 inputs the account number and password to the verification terminal 13 through the transmission path of the Internet 40 via the handheld communication device 30 to register at the verification terminal 13 and obtain the consumer from the verification terminal 13. The identification code and the consumer's private key. Thereafter, the consumer 11 purchases at least one item at the mall and counts the amount of the item to the checkout terminal 12.

Receiver, as shown in Figure 3, the figure is for the consumer and the checkout end The process of sending information about the amount of the item and the amount of the item received. An sonic transmitter 121 for encoding at the checkout terminal 12 encodes the amount of the item to generate the encoded amount of money.

The sound wave transmitter 121 of the checkout terminal 12 transmits the encoded money amount data to the handwritten communication device 30 of the consumer 11 for decoding by a sound wave transmission frequency of 16 kHz to 22 kHz. Sound receiver 301.

The sound wave receiver 301 of the handheld communication device 30 of the consumer 11 decodes the received encoded amount data and uses an algorithm pair of one of an RSA algorithm or an Elliptic Curve Cryptography Algorithm. The encoded amount data is encrypted with the consumer's private key to generate a Digital Signature.

Thereafter, the sound wave transmitter 302 of the handheld communication device 30 of the consumer 11 transmits the digital signature and the consumer identification code to the sound wave receiver of the checkout terminal 12 through the sound wave transmission path 20 at a frequency of 16KHz to 22KHz sound wave transmission. 122.

Thereafter, as shown in FIG. 4, the figure is a flow of verifying the identity of the consumer by the verification terminal. The sound wave transmitter 121 of the checkout terminal 12 transmits the digital signature and the consumer's identification code and the amount of the original item to the verification terminal 13 via the Internet 40.

The verification terminal 13 searches for a public key (Public-key) corresponding to the private key of the previously given consumer according to the received identification code of the consumer to decrypt the digital signature into another amount, and then the verification terminal 13 judges another One amount and the original If the amount of the items is the same, if the two amounts are the same, the verification is successful, and regardless of whether the two amounts are the same or different, the verification terminal 13 transmits the determined result to the checkout end of the consumer 11 through the Internet 40, respectively. 12.

The verification system with sound wave action payment proposed by the invention has the technical advantage that the process of two-way authentication not only ensures that the amount information of the items transmitted between the consumer and the checkout end is not intercepted by the hacker, and because of the sound The transmission distance of the signal is controllable, and the transmission and reception distance is very short, so the verification time will be very fast.
