Embodiment Construction

[0033] Below, the present invention will be described in detail with reference to the accompanying drawings.

[0034] Such as figure 2 As shown, this embodiment provides a method for realizing data transmission through sound, the method comprising:

[0035] The data sending end 10 selects the data to be transmitted, and uploads the data to be transmitted to the transit server; here, the data to be transmitted includes: information, files, pictures, audio and other data, the data format is not limited, and the size is not limited. limit.

[0036] The transfer server 20 packs the data uploaded by the received data sending end 10, generates a unique key and a dynamic encoding table with expiration time, and sends the key and the dynamic encoding table back to the data sending end 10;

[0037] The data sending end 10 encodes the key using the received dynamic encoding table, converts the key into a sound signal, and plays it;

[0038] Data receiving 20, after receiving the sou...

Abstract

The invention provides a method for achieving data transmission through voice. The method comprises that a data sending end uploads data to a transit server; the transit server packs the data to generate a secret key and a dynamic coding schedule and send the secret key and the dynamic coding schedule to the data sending end; the data sending end codes a key to convert the secret key into acoustical signals and play; the dynamic coding schedule is obtained from the transit server after a data receiving end receives the acoustical signals, the acoustical signals are decoded according to the dynamic coding schedule, and the secret key is obtained; and the data receiving end uses the secret key to obtain the data uploaded by the data sending end from the transit server and download. By means of the method, the data with big information content can be transmitted between the data sending end and the data receiving end, and transmission efficiency is improved. The secret key is transcribed in a transmission process and cannot be cracked and simulated, and reliability and confidentiality of data transmission are improved.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method for realizing data transmission through sound. Background technique [0002] Carrying on the data transmission through the sound, not only the realization process is simple, but also the realization cost is relatively low. We can retrieve many patent documents on data transmission through sound, for example, Chinese Patent Application No. 201110349377.4, the title of the invention is: a method for on-site mobile phone payment through audio signals, which is an application of the method of data transmission through sound. [0003] In the technical content disclosed by the patent, the method of data transmission through sound is as follows: figure 1 As shown in , the collection client calculates the check value of the transmitted data, adds the check start flag and the check value to the data to be transmitted to form the complete data, and then converts each va...
