Sound wave safety payment method and system

Abstract

The invention discloses a sound wave safety payment method and system. The method includes the steps that a payment end establishes an order and acquires transaction information corresponding to transaction data of the order from a network end database, the transaction information is encrypted through a secret key and subjected to RS coding to generate data frames, then the data frames are subjected to phase shift keying modulation to generate audio frames, and corresponding audio is played; after acquiring the audio, the payment end performs phase shift keying demodulation on the audio to generate data frames, the data frames are subjected to RS decoding and then decrypted through a pre-stored secret key to generate the transaction information, then corresponding transaction data are acquired from the network end database through the transaction information and displayed, and next, a transaction confirming instruction corresponding to the transaction data is sent to the network end database; after the transaction confirming instruction is received, payment operation is performed on the corresponding transaction data by the network end database. The payment method and system are convenient and safe to use.

Description

technical field [0001] The invention relates to the field of electronic payment, in particular to a sound wave safe payment method and system. Background technique [0002] Due to the rapid development of the e-commerce model in recent years, an online online store offline offline consumption model is becoming more and more popular. Merchants can push information such as business information, product information, coupons and payment coupons to consumers through the Internet. , Consumers select products casually online, compare physical objects offline, and make selective consumption after experience, and complete shopping offline by paying. [0003] Nowadays, there are various forms of offline payment. With the promotion of Internet technology and the development of mobile communication technology, the functions of mobile terminals such as mobile phones and tablet computers generally owned by consumers are becoming more and more powerful, and the form of mobile payment has q...

Problems solved by technology

[0004] Since offline mobile payment needs to use near-field communication technology to establish a bridge for information transmission between the cash register and the payment end, the existing methods of providing short-distance communication connections include Bluetooth technology, infrared data transmission, and near-field communication (NFC). ) technology and two-dimensional code scanning, etc., these technologies still have defects in various aspects, such as Bluetooth technology requires manual operation to establish a pairing connection between the two ends of the device before operation, the price of Bluetooth chips is relatively high, and merchants with large business volume may need quick payment It is time-consuming and inconvenient for certain occasions, and the hardware transformation cost of the equipment at both ends is high; because infrared data transmission is a line-of-sight transmission, the two communicating devices must be aligned and cannot be blocked by objects in order to connect successfully. The reliability and anti-interference ability are poor, the data transmission rate is low, and most mobile terminals are not equipped with infrared connection function; near-field communication NFC technology adopts two-way identification and connection, and the distance of about 10cm-20cm is within the high-frequency range of 13.56MHZ Work is a relatively safe short-range communication technology so far, but its NFC chip is expensive, and currently only a limited number of mobile terminals support this technology; two-dimensional code scanning technology has a better fault tolerance and recognition rate for payment, but for payment There are certain requirements for the camera lens of the cashier terminal and the display of the QR code, and the operation process takes a long time, requiring manual scanning of the QR code, which is inconvenient for quick payment

[0005] Combining the short-distance communication connection payment technology in the existing technology, it is generally impossible to perfectly meet the needs of fast, easy to use, low cost and easy to popularize for offline payment. Therefore, it is necessary to provide a fast, convenient, simple and easy to use A short-distance secure payment method and system that is low-cost and whose reliability, security and efficiency are guaranteed in the payment process to meet the requirements of convenient, safe, reliable and efficient electronic payment
