A method for transmitting data via mobile phone dialing communication or GRPS packet communication technology

Abstract

The utility model relates to a method for data transfer which is realized via communicating with the mobile phone dialing. A mobile phone and a data transfer target are used to realize the communication connection. The method of the utility model comprises a second extended memory card and a special read-in processing program which comprises a key, a test key and an encryption algorithm; the information is read according to given program. The transfer method is that: a mobile phone communication is set up after dialing; an electronic test key is generated by the processing program according to the transfer data and the mobile phone number; and is encrypted and sent to the communication target together with the transfer data. Real-time payment is an application case of the method. The method is characterized in that the key, the test key and the encryption algorithm in the data transferring are integrated with the memory card without significantly reducing the capacity of the mobile phone memory card. The security system of the communication system and the security system of the transfer system are separated, and the security is independently ensured. The existing system resource is exploited to the maximum; the mobile communication is brought into full play; the communication coverage is wide. The technical proposal of the utility model has the advantages of security, real time performance, efficiency, accuracy, rapidness and simple operation.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method for realizing data transmission by using mobile phone dial-up communication, especially belonging to the separation of the security systems of the communication system and the data transmission system, and the use of mobile phone dial-up communication or GPRS group communication technology to realize data transmission independently of each other method. Background of the invention [0002] In China, the use of mobile phone dial-up communication for data transmission and its specific application has been explored for many years, and it is illustrated by a specific application of the business---used to process bank payment business. In the early days of mobile payment, in terms of its information transmission form, it was just a simple communication. The result was consumption or payment with mobile phone bills. With the development of mobile phone technology, mobile pay...

Problems solved by technology

[0004] Although the payment method of telephone banking has been recognized by the society to a certain extent because it provides a transparent communication link between the customer and the bank, since the payment method provided is based on the voice transmission function, it cannot realize transmission encryption processing. The password is used in the process, but the account number and password are transmitted in clear code, which is very easy to be eavesdropped, and the security problem is obvious

[0005] The short message payment processing method of mobile phone has the problem of poor immediacy, which is difficult to meet the needs of real-time payment. In other words, there are also unsafe factors. In the real social environment, it is difficult for banks to fully entrust their own safety to third parties.

Therefore, the mobile phone SMS payment method is difficult to fully meet the needs of people or banks in terms of security.

[0006] The security system of the payment method based on the SIM card is very reliable in theory, but this security system is based on the use of the card issuer's own network. If the commercial bank uses the PKI certificate and SSL encryption protocol for mobile payment If it is fixed on the SIM card issued by the telecom operator, it is bound to completely build its own security system on the telecom operator. From the standpoint of a commercial bank, it will be unacceptable and unreliable

[0007] Although the mobile WAP network payment method has a certain degree of security through network demonstration in theory, due to the existence of operating system loopholes, network hackers and other problems, and due to the limitation of mobile phone hardware resources, mobile phones are still far behind in network protection. The protection level of important computer applications is difficult to reassure users

[0008] To sum up, considering the technical link of data transmission, mobile payment belongs to the cutting-edge achievements of making full use of the development of mobile phones. By utilizing the processing capabilities of smart phones, the existing bank credit processing methods are integrated into the functions of mobile phones, so that banks can use mobile phones. The communication function provides payment financial services to the public, but it is still not satisfactory especially in terms of its security
