After then network Cloud Server receives the information after encryption, retrieved by USB flash disk sequence number and be pre-stored in network cloud clothes
The decryption rule of business device, and decryption obtains random number and fileinfo, storage file information to network Cloud Server.
The invention has the advantages that：Can also be normal in the case of without network, upload important file money
Expect network Cloud Server, and lost without concern of data.
Brief description of the drawings
Fig. 1 is the system structure diagram of cloud USB flash disk storage of the present invention.
Specific embodiment
To describe technology contents of the invention, structural feature, the objects and the effects in detail, below in conjunction with implementation method
And coordinate accompanying drawing to be explained in detail.
Fig. 1 is referred to, the present invention provides a kind of data processing method of network cloud USB flash disk, the system that can apply to Fig. 1
In.USB flash disk in Fig. 1 has USB interface (USB, Universal Serial Bus), processing module, and USB flash disk
On be additionally provided with NFC (near-field communication, Near Field Communication) module, processing module and USB interface and NFC moulds
Block is connected, and USB flash disk is connected by USB interface with computer.Network Cloud Server is exactly the webserver, the service with network connection
Device, user can be in storage file above.
The present invention comprises the following steps：The NFC module of USB flash disk is contacted with the mobile phone with NFC function；So both can enter
Row communicates with one another.Computer client sends username and password to mobile phone by NFC module；It is exactly in fact that USB flash disk sends user name
, to mobile phone, mobile phone is by mobile phone radio frequency module forwards username and password to network Cloud Server for password；Network Cloud Server is tested
Card username and password, if mistake returns to error message, sends the network stored data of the user name if correct；Mobile phone
Computer client is sent to by NFC function after receiving the information of network Cloud Server；Computer client receive after to this
A little information are responded, if error message, computer Client-Prompt mistake, this method terminates, if the net of user name
Network data storage, then show network stored data.
Upload file operation can be then carried out, then computer client obtains the files passe operation of user；Computer client
End obtains fileinfo, and uploads fileinfo to mobile phone by the NFC module of USB flash disk；Mobile phone passes through mobile phone radio frequency module forwards
Fileinfo is to network Cloud Server.File so on computer is just stored on network Cloud Server, such memory capacity
The capacity of USB flash disk is also not limited to, USB flash disk can even not have the memory capacity for storage file.And do not have text on USB flash disk
Part, without worrying the problem that file is lost.
In certain embodiments, in order to simplify user's operating procedure, described " computer client is sent by NFC module and used
Name in an account book and password are to mobile phone " include step：Computer client sends register to USB flash disk；USB flash disk reads and is solidificated in USB flash disk encrypted area
The username and password in domain, and username and password to mobile phone is sent by NFC module.So USB flash disk is reformed into and common U disk one
Sample, as long as be dropped into file in USB flash disk by user, it is possible to be automatically uploaded on network Cloud Server.
In certain embodiments, in order to ensure USB flash disk during data are uploaded, file data will not be intercepted, described
" uploading fileinfo to mobile phone by the NFC module of USB flash disk " comprises the following steps：After USB flash disk receives fileinfo, generation one is random
Number, and with default the encryption rule encrypted random number and fileinfo related to USB flash disk user name, the information after being encrypted,
And the information after encryption to mobile phone will be uploaded；After then network Cloud Server receives the information after encryption, examined by USB flash disk user name
Rope is to the decryption rule for being pre-stored in network Cloud Server, and decryption obtains random number and fileinfo, storage file information to net
Network Cloud Server.This encryption rule can be when user name be logged in, and server is sent to USB flash disk.By random number, can be with
The information for avoiding someone from intercepting after encryption can easily crack out original data, increased the difficulty for cracking.
For the safety of data, " the uploading fileinfo to mobile phone by the NFC module of USB flash disk " comprises the following steps：U
After disk receives fileinfo, generate a random number, and with the default encryption rule encrypted random number related to USB flash disk sequence number and
Fileinfo, the information after being encrypted, and information and USB flash disk sequence number after encryption to mobile phone will be uploaded；Then network cloud service
After device receives the information after encryption, the decryption rule for being pre-stored in network Cloud Server is retrieved by USB flash disk sequence number, and decrypt
Obtain random number and fileinfo, storage file information to network Cloud Server.This encryption rule can be when dispatching from the factory
Storage is on USB flash disk.By random number, the information that someone can be avoided to intercept after encryption can easily crack out original data, increase
The difficulty for cracking is added.
If username and password is stored on USB flash disk, for the safety of USB flash disk, locking software can be set on USB flash disk,
When using USB flash disk, computer can install driving and the computer client of USB flash disk, first have to input and lock password, correctly can just carry out
Below step of the invention, can not otherwise carry out below step of the invention.
Embodiments of the invention are the foregoing is only, scope of patent protection of the invention, every utilization is not thereby limited
Equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations
Technical field, be included within the scope of the present invention.
