Abstract
The invention mainly relates to the field of logistics and security and brings forward a visualized digital seal apparatus.A random number generator is triggered by changes of a seal state in order to generate a string of digit combinations in the state. An expression of Arabic numerals is formed by the string of digit combinations and incremental digit combinations. As a digital signature in the present state of the invention, a public key used for checking sealing operation at this time is formed and obtained by a checker in any manner. A display module driven by a button is used for making an artificial comparison between a digital combination in display and a known public key digit combination as required. By controlling the relations between display modes, generation and display of random numbers, random numbers of each time cannot be generated in a real-time manner. A cheat-proofing time interval, during which a special delay time display mode is executed, is inserted based on frequent generation of random numbers. While ensuring security in the first place, digit numbers of random numbers are significantly reduced for facilitating human eye identification and usage. Therefore, defects of a conventional seal and an existing electronic seal are solved.
Description
Technical field
The invention mainly relates to logistics field and security fields, more precisely, relate to material object, in the links such as circulation, use or keeping, safety and the integrity of target item is carried out evidence protection.
Background technology
All commonly use strip of paper used for sealing in the every aspect of social activity at present and be used as safety verification evidence, in order to guarantee article safety in the processes such as circulation, use, keeping. The kind of strip of paper used for sealing mainly has traditional disposable seal such as papery strip of paper used for sealing, lead sealing, metal seals, a plastic paper strip seal etc., and along with the development of technology starts appearance can single use or reusable e-seals.
No matter traditional disposable seal, be papery or other materials, and the evidence protective capability that article are sealed up for safekeeping by it is all very weak, is primarily present defect as follows:
Need when opening to destroy strip of paper used for sealing every time, both bothered in using and also produced inevitable cost overhead;
The time sealed up for safekeeping every time and open cannot be recorded;
It is easy to by counterfeit and forgery.
Due to the tradition unsurmountable defect of strip of paper used for sealing, along with the development of information technology, e-seals starts to occur and well solve above three problem. But the design of all of e-seals, it it is no matter single use or reusable, it is required for being carried out machine recognition by one or a set of extra special equipment, just carrying out proof validation after being completed the collection to its electronic data by contact or non-contacting mode or read, this results in the following problem of existing e-seals:
The strip of paper used for sealing electronic data of existing e-seals is the global unique ID number code distributed by each e-seals, adds the sensor status information of e-seals, the two coded combination together into. So, these e-seals data just can be acquired by machine and identify, then carry out automatic or manual checking again. Therefore being required for extra special equipment in each use procedure to participate in, operation had both bothered and has brought use cost also higher, actually substantially increased the importing cost of user;
So the e-seals cost of design is also significantly high, and the complexity of design directly influences the dependability of equipment, and these all cause e-seals and do not substitute the difficult situation of tradition strip of paper used for sealing application in a large number.
Therefore, on market in the urgent need to be a kind of new strip of paper used for sealing proof device, particularly in the logistics security under ecommerce develops rapidly and dispute, the problem that should overcome tradition strip of paper used for sealing, solve the drawback of existing e-seals again, with low cost, flexible and convenient to use, work Maintenance free reliably and with long-term.
Summary of the invention
Herein below provides the brief overview to one or more embodiments, in order to provide the basic understanding of some aspects to this type of embodiment. This general introduction is not the extensive summary to one or more than one embodiment, and both without wishing to key or the deciding factor of pointing out described embodiment, also without wishing to the scope describing this type of embodiment. Its sole purpose is some concepts presenting described embodiment by brief form, using the preamble as the more detailed description content presented after a while.
For the defect overcoming tradition strip of paper used for sealing and existing e-seals to exist, the present invention proposes a kind of visualization digital Sealing arrangement. The mentality of designing of existing e-seals is all from adopting machine to be identified the angle with data acquisition, it is that machine processing is accomplished by first defining for which e-seals, sealing up for safekeeping and opening followed by e-seals, this design concept result in and is identified as root with e-seals body, but the most basic function of strip of paper used for sealing itself is simply concerned about that its envelope opens state but not strip of paper used for sealing body, and this is a great design misconduct. Therefore, the design concept that the present invention proposes is then electronical display state, eye recognition state.
The present invention pay close attention to envelope open state, the electronical display mode on display module can be the various ways such as numeral, word, figure or combine express. But identify as human biological and gather, it is desirable to mode be Arabic numerals, be also simultaneously the program coded system that is easiest to produce, cost is also minimum. Therefore, currently preferred user-machine interface is exactly the state expression way of the present invention that Arabic numerals combination is formed, and this also complies with the traditional habit under intended applications of the present invention. In theory, under providing enough security guarantee premises, adopting more simple electronic state to express, the more low use of cost is also more convenient. This is the present invention with other designs essential distinctions, so could both solve the defect of tradition strip of paper used for sealing, the problem that can solve again existing e-seals.
Its particular content comprises the present invention itself and does not fix id number, open sensor states with the envelope of the present invention and be characterized as drive source, being generated the current state digital signature as the present invention of the string number combination under this state by its triggering strip of paper used for sealing internal random number producer, if sensor states does not change, the digital signature of the present invention remains unchanged.
This digital signature is completed eye recognition by the display module of the present invention, but the display process of display module is driven by button, envelope do not open sensor states change and drive. Record envelope every time is opened the corresponding random number digital signature after sensor states change and other information such as timestamp etc. by the internal storage of the present invention, just can by eye recognition and collection on display module by the button of the present invention.
In actually used process, when the present invention seals up for safekeeping by turning on into, opened the sensor states driving tandom number generator that changes by envelope and produce the combination of string number available for display, i.e. dynamic digital signature number, it is identified once this time seal up for safekeeping, this digital signature number just becomes the checking present invention and this time seals the PKI of operation up for safekeeping, can be obtained by any mode authenticatee, needs to the present invention this time the state of sealing up for safekeeping is verified time, display module is driven by the button of the present invention, it is accomplished manually the comparison process that string number combines and known public key digital combines that the present invention shows, assist without any other equipment. if the present invention this time seals up for safekeeping, state is not confirmed to be unlocked, even if being again introduced into sealing up for safekeeping, envelope opens the change of sensor states and causes that a new dynamic random number produces the digital signature becoming under current state, but owing to correctly cannot mate with known public key digital combination so that unidentified open operation is recorded and finds.
A string random number numeral as verification public key combines an actually pseudo random number, and how many composition figure places determines its probability size likely repeated. When constantly opening sensor states change and just can attempt the pseudo random number that generation is identical by sealing, the safety of the present invention is dependent on the time of probability size that this information is reproduced and needs. In theory when this string random digit combination figure place is infinitely many, the probability so repeated is just infinitely small, and actually this numeral combination figure place to meet eye recognition, human brain memory and the convenience manually pass on, therefore this random digit number in theory should be more few more convenient, and therefore this is conflict.
Another embodiment of the present invention, increases the numeral combination of one or more incremental rolling code, amounts to isomorphism with random number blockette and become the checking Explicit Expression mode of the present invention, it is possible to significantly reduce random number figure place under the premise ensureing safety.
Wherein preferably, for reducing the figure place being incremented by numeral combination, being incremented by numeral combination is express currently displaying random number numeral to combine the number of times occurred, such expression way is clearly succinct, it is possible to ensure safety when reducing random number figure place.
One numeral combination is it desired to be easy to be identified by the mankind, remember and pass on, and except figure place is few, it is also possible to be the expression having other public meanings, the numeral such as express time stamp combines. Therefore another is preferred, is the timestamp produced with current random number, reaches mode as the digital combination table being constantly incremented by, and a small amount of random number figure place so can also be used to coordinate timestamp to provide higher safety.
Another embodiment of the present invention, in order under the premise ensureing safety, effectively reduce the digit in state expression way of the present invention, the relation between display is produced by the display pattern and random number controlling the present invention, random number each time is made to produce can not be shown to user in real time, the utilization envelope being prevented effectively from malice is opened sensor states change and carries out random number pairing by this, because show delay time every time, matches significantly lengthening malice random number the time to spend.
Another embodiment of the present invention, can increase and anti-fraud detection is set, if random number produces excessively frequently to exceed default warning value, then trigger an anti-fraud time period, perform special display pattern within the time period, to reduce random number malice pairing ability further.
