Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
Referring to FIG. 1, Fig. 1 is the composition figure of the digital cash management system of present invention isolation wallet,
The digital cash management system 100 of isolation wallet of the invention includes the cold wallet 10, extremely of at least one non-networked
The hot money packet 20 and background server 30 of a few networking, cold wallet 10 are communicated with hot money packet 20, hot money packet 20 and background service
Device 30 connects.
The cold wallet 10 is for storing digital cash key, and in transaction, construction trades and completes digital cash key pair
The signature of transaction, the transaction data generated that will trade are converted to ciphering two-dimension code image or digital label, the hot money packet 20
For scanning the image in 2 D code of cold wallet or parsing the digital label of cold wallet 10 by near-field sensing to obtain cold wallet 10
Transaction data, and by the transaction data of acquisition by network transmission to background server 30.
The hot money packet 20 is also used to obtain newest transaction data from background server 30 by network, and by the transaction
Data are converted to ciphering two-dimension code image or digital label, and the cold wallet 10 is also used to the image in 2 D code of scanning calorimeter wallet 20
Or the digital label for by near-field sensing parsing hot money packet 20 and is parsed the transaction data with obtaining the transaction data of hot money packet
The corresponding remaining sum of digital cash is obtained afterwards；
The background server 30 by digital cash transaction data synchronization to public data network 40, while by common data
Newest transaction data synchronization is to background server 30 in network 40.
The embodiment of the present invention image in 2 D code using the two dimensional code storing data of encryption, it is a kind of encryption and compression
Coding, can guarantee data safety and capacity be very big, can effectively solve transaction data greatly and transmission safety problem, ensure that cold
The interactive performance of wallet 10 and 20 data of hot money packet.
The embodiment of the present invention is due to transmitting data or near field by ciphering two-dimension code between cold wallet 10 and hot money packet 20
Induction transmission data, cold wallet 10 is to be in the state that do not network, i.e., cold wallet 10 is not connect with external network, this mode
It ensure that the separation of cold wallet 10 and hot money packet 20, it is ensured that digital cash key with Internet contact, is not both able to satisfy number in this way
The demand of moneytary operations, and can ensure the safety of digital cash.
