Abstract
The utility model discloses an anti-fake graph code reading system. The anti-fake graph code reading system includes a client-side computer. And the anti-fake graph code reading system also includes a USB secret key disc, a client-side printer and a code-scanning recognizer. The client-side printer and the code-scanning recognizer are both in communicational connection with the client-side computer. The USB secret key disc is inserted in the client-side computer. The security treatment of anti-fake graph codes of one code one encryption is realized by adopting a structural method of utilizing secret keys and the code-scanning recognizer, an SM1 decryption technology, a digital abstract comparison technology and a digital signature verification technology. The anti-fake authentication of the anti-fake graph codes is realized by adopting a digital watermark technology and an invisible pixel technology. Functions of recognizing the anti-fake graph codes by a dedicated device safely and validly and decrypting information in the graph codes safely and accurately are realized. The code-reading efficiency of the anti-fake graph code reading system is improved. Two-dimensional codes can be used repeatedly, so that the use cost of the anti-fake graph code reading system is reduced.
Description
Technical field
The utility model relates to the field of reading of two-dimentional security code, relates in particular to a kind of false proof figure code reading system.
Background technology
Along with the high speed fast development of global infotech and coding techniques, planar bar code technology is developed rapidly.So-called two-dimension code just refers to (refer in particular on the two-dimensional directional) according to certain rules the chequered with black and white rectangle square formation that distributes, the barcode technology of new generation of record data symbolic information on the plane with specific geometric figure.It is by a two-dimension code Matrix Pattern and a two-dimension code numbering, and the comment of below forms, have to contain much information, but 1850 capitalizations of outfit as many as or 2710 numerals or 1108 bytes, or more than 500 Chinese character, approximately higher tens times than common bar code information capacity; Error correcting capability is strong, when two-dimensional bar code causes local damage because of perforation, stained etc., can correctly be distinguished in the same old way, and damaged area reaches 50% still can recover information; Recognition speed is fast, can digitized information encode picture, sound, literal, signature, fingerprint etc., shows with bar code; Can represent the multilingual literal; But presentation video data; Reliability of decode is high, and it is more much lower than common bar code decoding error rate 2/1000000ths, and the bit error rate is no more than 1/10000000th; Comprehensive recognition, redundance are high, and cost is low, easily make, and the characteristics such as durable realize the with no paper of information, and are efficient, and safety is convenient, quick, the series of advantages such as easily use, environmental protection.Merchant's secret skill art adopts the effective means of encrypting, the validity of guarantee information, and integrality, availability, confidentiality provide comprehensive security strategy and the safety guarantee of enterprise-level.
And the anti-damageability of two-dimension code of the prior art is not fine, and easily recognition is not out; And encoded content is common text, and general software can be understood the content of two-dimensional bar code.Two-dimensional bar code can only be as disposable information carrier like this, can not Reusability, can not as identify label, increase its use cost.
Therefore, prior art has yet to be improved and developed.
The utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of false proof figure code reading system, improving reading code efficient, can the Reusability two-dimension code, and reduce its use cost.
The technical solution of the utility model is as follows:
A kind of false proof figure code reading system, it comprises client computer, it is characterized in that, described false proof figure code reading system also comprises usb key dish, client printer and sweeps code reader, described client printer, the described code reader of sweeping all communicate to connect with client computer, and described usb key dish is plugged on the described client computer.
Described false proof figure code reading system wherein, is provided with the USB interface for grafting usb key dish on the described client computer.
Described false proof figure code reading system, wherein, the described code reader of sweeping is that false proof figure code is swept code reader.
A kind of false proof figure code reading system that the utility model provides, adopt key and the frame mode of sweeping code reader, and SM1, SM2 and SM3 technology are come one yard one close false proof figure code carried out safe handling, by digital watermark technology, stealthy pel technology false proof figure code being carried out antifalsification identifies, realized the false proof figure code of the safe and effective recognition of specialized equipment instrument, the function of information in the safety and precise deciphering figure code, improved its reading code efficient, can the Reusability two-dimension code, reduced its use cost.
Description of drawings
Fig. 1 is the structural representation of false proof figure code reading system in the utility model.
Embodiment
The utility model provides a kind of false proof figure code reading system, and is clearer, clear and definite for making the purpose of this utility model, technical scheme and effect, below the utility model further described.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model provides a kind of false proof figure code reading system, as shown in Figure 1, it comprises client computer 1, described false proof figure code reading system also comprises usb key dish 2, client printer 3 and sweeps code reader 4, described client printer 3, the described code reader 4 of sweeping all communicate to connect with client computer 1, and described usb key dish 2 is plugged on the described client computer 1.Described client computer 1 can comprise a CPU and internal memory, wherein CPU adopts InterQ8400, in save as 2G, hard disk is 320G, and the below arranges several USB mouths and connects, and is used for being connected with described usb key dish 2, the described code reader 4 of sweeping respectively, come false proof figure code is carried out correct recognition and the described usb key dish 2 that inserts is carried out accurately authentication, improved its reading code efficient, can the Reusability two-dimension code, reduced its use cost.
In another preferred embodiment of the present utility model, described usb key dish 2 adopts the USBKEY combination disk of the safe circumference in sea, and model is SJK0928.Preserve three grades of keys in the described usb key dish 2, can only carry out write operation for whole described usb key dish 2, can not carry out read operation, finishing of write operation will be passed through specific program, carry out this operation by keeper's employing that PIN code is arranged, and all encryption and decryption operations is all carried out in described usb key dish 2, and dissimilar key is stored among the USBKEY of different colours and distinguishes, and has made things convenient for operating personnel's management.
Further, the described code reader 4 swept is swept code reader for false proof figure code, comes false proof figure code is carried out correct effectively recognition, it has, and accuracy is high, recognition speed fast, accurately, convenient, simple operation and other advantages.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection domain of the utility model claims.
