Data exchange unit and network based data exchange method

Abstract

This invention discloses one data exchanging device used to exchange data based on outer internet, which is characterized by comprising control unit, communication unit, memory unit, wherein, the communication unit is to insert the data exchange device into outer network and to establish the device to the outer net data channel to realize the data receiving and sending; the said memory unit is to store data; the said control unit is to connect the communication unit and memory unit to control the unit to realize the establishment of data.

Description

technical field [0001] The invention relates to data information transmission and processing technology, in particular to a data exchange device for transmitting and storing data and a network-based data exchange method. Background technique [0002] In recent years, with the rapid development of society and information technology, data has become more and more important to people, and information exchange and communication between people have become increasingly frequent, such as frequent use of various data processing systems to achieve data exchange. [0003] At present, various existing technologies have been developed in the industry to realize data exchange and sharing between various data processing systems, and between data processing systems and other digital devices. [0004] One prior art employs removable external storage devices. Firstly, establish a data connection between the external storage device and the first data processing system, and the data to be sha...

AI Technical Summary

Problems solved by technology

[0008] However, the wireless data communication device of the prior art has some disadvantages: first, it can only be connected to the Internet through a wireless transceiver module to realize Internet access to send and receive information, which is not a real data exchange and sharing between devices, so that data The exchange of communication is relatively complicated; secondly, the device must be connected with various data processing systems through interfaces, and data exchange can only be realized by cooperating with data processing systems; secondly, the receiving and sending of data information can only be realized through public wireless networks, so that Its scope of application is limited

[0009] In addition, because the management formats of the file systems used by different data processing systems are sometimes different and cannot be compatible, and the wireless data communication device in the prior art cannot realize the adaptation between different formats, so that sometimes the data cannot be successfully completed. read and write operations

[0010] In addition, the wireless data communication device in the prior art cannot implement data encryption and decryption, as well as user security authentication, and cannot guarantee the security of data storage and transmission.

and cannot provide permission control over data access
