Specific embodiment
To keep the purposes, technical schemes and advantages of this specification embodiment clearer, have below in conjunction with this specification
The technical solution of this specification embodiment is clearly and completely described in body embodiment and corresponding attached drawing.Obviously, described
Embodiment be only this specification a part of the embodiment, instead of all the embodiments.The embodiment of base in this manual, this
Field those of ordinary skill every other embodiment obtained without making creative work, belongs to this explanation
The range of book embodiment protection.
Below in conjunction with attached drawing, the technical solution that each embodiment of this specification provides is described in detail.
Firstly, be contactless static signature system architecture schematic diagram provided by the embodiments of the present application shown in referring to Fig.1,
Online wallet end 11, static signature end 12 are specifically included that in the static signature system；In addition, it can include assist carry out from
Other existing apparatus of line signature operation, this will not be repeated here.Shown in referring to Fig.1, online wallet end 11 and static signature end 12
It is mainly used in during the trade management of decentralization application, static signature operation is realized by non-contact data, at this
In one signature process, static signature end 12 does not need be inserted into etc. directly contacting with any online equipment, thus, it avoids black
Visitor's attack is possible, improves the safety and reliability that transaction data is digitally signed.
It should be noted that being carried out between online wallet end 11 and static signature end 12 in system architecture shown in FIG. 1
The interaction of non-contact data is distinct from existing wired or wireless data communication interaction, but will by cordless
Transaction data is transmitted, wherein during transmission of transaction data, static signature end 12 (is not included in any online equipment
Line wallet end 11) carrying out contact connection or contactless connection, (connection here refers to data connection, carries out data connection
Both sides afterwards can carry out data interaction).
Embodiment one
It is a kind of flow diagram of contactless static signature method provided by the embodiments of the present application referring to shown in Fig. 2,
The static signature method is based on the non-contact data interactive operation between online wallet end 11 and static signature end 12, packet
It includes:
Step 21: the first non-contact data is showed static signature end 12 by online wallet end 11.
Wherein, transaction data is carried in first non-contact data.
When specific implementation, after line wallet end 11 receives transaction data, which is not digitally signed
Operation, but transaction data is subjected to data conversion, the first non-contact data is generated, and show static signature end 12, had
The exhibition method of body can be selected according to the type of the first non-contact data.
Wherein, the first non-contact data includes: one of encoding of graphs, vocal print, image or multiple combinations.
Correspondingly, the transaction data received is converted to encoding of graphs by online wallet end 11, can specifically pass through figure
Encode online Core Generator, by transaction data text and/or the transaction contents such as number be converted to encoding of graphs format；

It can be raw according to the user label of the user name of any user or other identity user uniqueness by asymmetric encryption techniques
Public key and private key in a pair.Wherein, which is stored in static signature end, only user it is found that and public key to the public (including user
And the corresponding terminal of user, for example, the nodal terminal of block chain network) it is visible.Static signature end is using private key to acquisition
Transaction data carries out data encryption to realize digital signature；Correspondingly, the nodal terminal of block chain network then uses public key to
Two non-contact datas carry out legitimate verification.
Step 23: static signature end 12 shows the second non-contact data to online wallet end 11.
Wherein, the transaction data after digital signature is carried in second non-contact data.
In this specification embodiment, it is contemplated that the static signature system where static signature end 12 and decentralization application
Interior all on-line equipments or equipment is all non-contacting (no data connection), then, static signature end 12 is to getting
After transaction data is digitally signed, it can not be transferred directly to block chain network, therefore, which can be to number
Transaction data after signature is converted, and generates the second non-contact data, and show online wallet end 11, specific to show
Mode can be selected according to the type of the second non-contact data.
Wherein, the second non-contact data includes: one of encoding of graphs, vocal print, image or multiple combinations.
Correspondingly, the transaction data after digital signature is converted to encoding of graphs by static signature end 12, can specifically be passed through
The online Core Generator of encoding of graphs, by the transaction data after digital signature text and/or the transaction contents such as number be converted to
Encoding of graphs format；
Transaction data after digital signature is converted to vocal print by static signature end 12, can specifically be generated online by vocal print
Tool, by the transaction data after digital signature text and/or the transaction contents such as number be converted to identifiable vocal print format；
Transaction data after digital signature is converted to image by static signature end 12, can specifically be generated online by image
Tool, by the transaction data after digital signature text and/or the transaction contents such as number be converted to image.
Step 24: line wallet end 11 from second non-contact data obtain digital signature after transaction data,
And it is sent to block chain network.
Similarly, online wallet end 11 can also obtain number from the second non-contact data that static signature end 12 is shown
Transaction data after signature, specific acquisition modes can accordingly be selected according to 12 exhibition method of static signature end.Online money
Wrap end 11 after obtaining the transaction data after digital signature, by the transaction data after the digital signature be sent to block chain network into
Row trade management.
It should be understood that encoding of graphs can be two dimensional code or bar code in this specification embodiment, specific figure is compiled
Code format can be according to user demand flexible setting.
Optionally, image involved in this specification embodiment may include: dynamic image (such as: image frame, photo
Deng) or still image (such as: image, video etc.).
