Description
Technical field
The present invention relates to computer network security technology field, for the fail safe protection of private data when network is shared, particularly relate to a kind of network security based on private data and share method and communication terminal.
Background technology
Along with the develop rapidly of computer and information technology especially network technology, data message has become the most key resource of entire society, and enterprises and institutions need the data message of share and access to get more and more, and more and more important.Therefore, how to ensure the information security of private data when network is shared, become significant problem urgently to be resolved hurrily.At present, in order to protect the safety of shared private data Network Based, the following two kinds of methods of main employing: is be encrypted data.Adopt cryptographic algorithm to be encrypted data to store and transmission, make it be difficult to analyze decoding, realize maintaining secrecy and safety of private data.Two is arrange access rights to data, and conduct interviews control.Different access rights are set for different users, and before its access private data, legitimate verification are carried out to its identity.Adopt the system that realizes of above-mentioned two kinds of methods to have a lot, substantially partly can solve problem of data safety, but also all Shortcomings:
1) adopting encryption technology, the private data be stored on disk being encrypted, when being decrypted by during access to netwoks private data.This method ensure that the storage security of private data, but the fail safe of private data in Internet Transmission is not processed, therefore, the leakage problem of private data in network transmission process may be appeared at.
2) adopt encryption technology, the private data of Internet Transmission is encrypted, thus ensure the fail safe of private data in network transmission process.This implementation method ensure that the fail safe of the Internet Transmission of private data, but does not process the fail safe that private data stores, and therefore, once the disk unit storing private data exposes, the leakage of private data is apparent.
3) encryption technology is adopted, not only to the private data encryption be stored on disk unit, and to the private data encryption in Internet Transmission.Although the method can ensure storage security and the Internet Transmission safety of private data, owing to carrying out too much encryption and decryption process to data, systematic function is difficult to ensure.
4) adopt access control, the private data for different user arranges different access rights, to ensure that each user can only access the private data of oneself.Obviously, this implementation method can not ensure storage security and the Internet Transmission safety of private data.
5) encryption technology and access control is adopted, not only the private data encryption be stored on disk unit, and the private data encryption in Internet Transmission, arrange different access rights for different user, the method can solve the safe sharing problem of private data preferably simultaneously.But the actualizing technology of employing the method is more, broad categories, all the time solution of neither one the whole series.
In summary, obviously there is inconvenience and defect in actual use, so be necessary to be improved in the Sharing Technology in Network of existing private data.
Summary of the invention
For above-mentioned defect, a kind of network security based on private data is the object of the present invention is to provide to share method and communication terminal, it achieves the stereoscopic protective system that a kind of private data network is shared, not only ensure that the storage security of private data when network is shared and Internet Transmission safety, and facilitate easy-to-use, comprehensive high-efficiency, achieve the real-time synchronization of shared data simultaneously.
