Method for applying general-purpose information code to hand-held radio communication device safety trading

Abstract

The invention relates to a method for applying general information code in safe transaction of handheld wireless communication devices, which transmits the pointer of database as information but not important data content. Therefore, even transmitted report is thieved or usurped, and the leaked one is meaningless database pointer but not initial data. Assisted by three reinforced protection methods provided by the invention, the method can correctly judge if the pointer has error occurrence in transmission. The method can be used to judge commodity trade and use personal data for identity authentication and theft prevention, thereby effectively resolving error occurrence in pointer transmission. The method can completely confirm the security of general information code, to realize safe and convenient electronic commerce transaction method.

Description

technical field [0001] The invention relates to the technology of wireless access to data, in particular to a method for applying universal information codes to secure transactions of hand-held wireless communication devices. Background technique [0002] Today's e-commerce transaction technology has become more and more mature, and the technology and application of bar codes to transmit shopping product information or access databases through the Internet or mobile phone networks have begun to rise. In advanced countries such as Japan and other places, the acceptance of applications such as using barcodes on products and accessing product-related information via mobile phone networks is quite high. FIG. 1 shows a camera phone 10 including a digital camera 130 and a phone 120 . It can not only use the digital camera 130 to capture images, but also transmit the captured images through the mobile phone 120 . [0003] This combination of digital camera 130 and cell phone 120 ...

AI Technical Summary

Problems solved by technology

However, the barcode transmission technology does not have the most important security mechanism, and the encryption / decryption mechanism of the existing cryptographic technology is mostly added to the barcode transmission process, and it is assumed that a certain degree of security can be achieved by using the existing encryption / decryption mechanism

However, using public / private keys or other encryption / decryption methods, in addition to increasing the cost and difficulty in design, still cannot prevent deliberate cracking by interested people

It can be seen that there is still room for improvement in the method of applying the existing barcode to the handheld wireless communication device.
