As shown in Figure 3, CCTV camera under the Quick Response Code of the embodiment of the present invention generates and relate in verification method gate inhibition's environment, wherein, this CCTV camera can be the CCTV camera for monitoring doorway situation, also the top of door can be mounted in for checking the CCTV camera of guest's situation, and, in order to realize the Quick Response Code checking of user identity, the function supporting Quick Response Code identification is added in this CCTV camera, and for the verification process of Quick Response Code, this processing unit can be external processing unit as shown in Figure 3, also can this processing capacity be integrated in the system of CCTV camera, thus make CCTV camera realize the Quick Response Code authentication function of identifying user identity, in addition, for the generation of Quick Response Code including subscriber identity information, devise in the present embodiment one " Quick Response Code generation application program ", on its smart mobile phone that can be arranged on user or panel computer, for the generation of Quick Response Code.
In this example, for the mobile phone of user, the explanation that this application program carries out embodiment is installed, the authentication information of user is comprised in the Quick Response Code generated to make this application program, after this application program of user installation, first user needs to input corresponding user profile, namely the user cipher for opening gate of user is belonged to, and user name, same, also the identical user name needing input and user to input in the application in CCTV camera or in the external processing unit of CCTV camera connection and user cipher, certainly in actual applications, both can independently input when arranging user name and user cipher for CCTV camera side and user side, also can be realize the synchronous of user name and user cipher by communication, in a word, as long as user name and user cipher are consistent in the information that CCTV camera side and application program side preserve, the present invention is for concrete configuration mode and be not construed as limiting.
So for the generation method of Quick Response Code, user to go home from the outside or go to work enter company time, all by clicking this application program, this application program is made to generate a dynamic two-dimension code in real time, concrete mode is, this application program can determine the key message of the user that will generate Quick Response Code, wherein, the user name that this key message inputs before can being user, also current time, also can be the random random number produced, certainly can also be the combination in any of above-mentioned three kinds of information, and be the auxiliary checking realizing user identity due to the effect of this key message, therefore, the content that this key message comprises is not limited to this, it also can comprise other the user profile for authentication, in addition, for current time, its accurate unit can be hour, also can be minute, also or second, the present invention is to this and be not construed as limiting.
And in order to make the digital signature information comprising user in the Quick Response Code of generation, also need the user cipher determining that user pre-enters, then according to pre-configured algorithm, computing is carried out to this key message of user (being user name, current time (be accurate to hour), random number) and user cipher herein herein, thus the digital signature information of generation user;
And for this pre-configured algorithm, it can be symmetry algorithm also can be asymmetric arithmetic, object is the digital signature realizing subscriber identity information.
Then, the digital signature information generated and user name, current time (be herein accurate to hour), random number are combined, thus generates anti-counterfeiting information;
Finally, according to Quick Response Code coding techniques, this anti-counterfeiting information is encoded, thus on mobile phone, generate a dynamic two-dimension code.
By specifically describing above and can finding out, the present invention proposes a kind of for the subscriber authentication mode based on Quick Response Code under gate inhibition's environment, thus avoid the large problem of potential safety hazard existing when keyboard password input mode and contactless card mode carry out opening gate, because the popularization degree of current smart mobile phone and panel computer is quite high, therefore, the application program of generated Quick Response Code proposed by the invention is arranged on mobile phone or the mode of other intelligent electronic devices not only implements simple to the unlatching realizing gate inhibition, and use also safety, and popularization degree is quite high.
So after generating the Quick Response Code for opening gate, generation just can have the mobile phone screen of Quick Response Code before the CCTV camera supporting two-dimensional code authentication function, carry out the scanning of Quick Response Code by user, also can arrange a button on gate inhibition in actual applications, user triggers the Quick Response Code scan function of CCTV camera by clicking this button.
After CCTV camera is to the Quick Response Code scanning in user mobile phone screen, just can decode to this Quick Response Code, thus the digital content in reading Quick Response Code, comprise, the key message of digital signature information and user, if so the key message part of the user of this Quick Response Code is not tampered, the content that key message herein comprises should be that when generating this Quick Response Code, determined key message is consistent with the application program of user.
Same, the user name that this key message inputs before can being user, also current time is (namely, the current time of user when using application program to generate Quick Response Code), also can be the random random number produced, certainly can also be the combination in any of above-mentioned three kinds of information, and be the auxiliary checking realizing user identity due to the effect of this key message, therefore, the content that this key message comprises is not limited to this, it also can comprise other the user profile for authentication, in addition, for current time, its accurate unit can be hour, also can be minute, also or second, the present invention is to this and be not construed as limiting.
And the Quick Response Code generated in mobile phone side due to user also have be photographed may, therefore, monitoring camera pusher side is before verifying the digital signature information read, the checking of validity will be carried out to this Quick Response Code, in the present embodiment, concrete verification mode is can according to predetermined time rule (such as+0.5 hour,-0.5 hour) and the key message that reads from Quick Response Code in current time (namely, the current time of user when using application program to generate Quick Response Code, such as 9:00) determine scope effective time of Quick Response Code, due to the front and back 0.5 hour that the time rule in this example is current time, scope effective time of the Quick Response Code so herein determined is then 8:30 ~ 9:30.
Certainly, in actual applications, regular for this predetermined time, it can carry out different settings according to actual needs, and object is to realize for the judgement of Quick Response Code on available time, namely, after exceeding scope effective time, this Quick Response Code ceases to be in force automatically, and so just can effectively prevent when occurring after the Quick Response Code that generates of user side taken pictures by lawless person, by user this Quick Response Code used again pretended to be the situation of use by lawless person.
And in order to determine that whether this Quick Response Code is effective in time, also needs to determine the current time, then determine that whether Quick Response Code is effective according to scope effective time of Quick Response Code with this current time.
In one embodiment, according to Quick Response Code effective time scope and the current time determine that Quick Response Code whether effectively time, be divided into following two kinds of situations, be when the current time (such as 9:20) is within scope effective time (8:30 ~ 9:30) of this Quick Response Code, so then show that this Quick Response Code is effective; Another kind of situation is then when the current time (10:00) is not within scope effective time (8:30 ~ 9:30) of Quick Response Code, so then show that this Quick Response Code lost efficacy, so then without the need to carrying out follow-up Quick Response Code verification step, thus avoid unnecessary verification step.
Only determining, in the effective situation of this Quick Response Code, just to verify the digital signature information of Quick Response Code, be specially: the user cipher determining corresponding key message; And according to the pre-configured algorithm of respective user, computing is carried out to above-mentioned key message and user cipher, thus obtain operation result; Finally operation result and digital signature information are contrasted, and verify the true and false of Quick Response Code according to comparing result.
Wherein, due to the pre-configured user of monitoring camera pusher side user name and with user name user cipher one to one, therefore, in one embodiment, the user cipher of user can be determined according to the key message read from Quick Response Code, namely determine corresponding user cipher according to the user name in key message.
And for the pre-configured algorithm of respective user, it can be symmetry algorithm, also can be asymmetric arithmetic, but it must be equal to mutually with the algorithm adopted when Quick Response Code generates, namely, come to identical information (namely based on the identical algorithm of use in the present embodiment, from the user name that Quick Response Code reads, current time, random number and the user cipher consistent with user side read from monitoring camera pusher side) carry out that the principle of computing verifies the Quick Response Code true and false, concrete, namely, operation result and digital signature information are contrasted, and the true and false of Quick Response Code is verified according to comparing result.
Wherein, in one embodiment, when the true and false according to comparing result checking Quick Response Code, when identical with digital signature information according to comparing result determination operation result, so can determine that this Quick Response Code is true; And when not identical according to comparing result determination operation result and digital signature information, then can determine that Quick Response Code is the Quick Response Code forged.
So, when determining that Quick Response Code is genuine Quick Response Code, namely after identifying user identity is legal, monitoring camera pusher side just can send a request to access control equipment system, thus opens the gate inhibition be attached thereto.
In addition, adopted is for different user configures the mode of different user ciphers to realize technique scheme in the above-described embodiments, thus ensure that the password of each user is independent mutually, prevent because certain user reveals the situation that each user of needs that password causes remembers new password again, and, can entering with certain user of limit, safety coefficient is higher.
But, in actual applications, for security requirement in lower or situation of special circumstances, also multiple user can be made to share a password to realize technique scheme, namely the user cipher non-private in technique scheme, but global secret, same, for corresponding user name, it can be the unified agreement user name that multiple user shares, accordingly, when monitoring camera pusher side and user side carry out user profile pre-configured, then without the need to inputting user name, because it is default value, and only need to configure (namely inputting) identical user cipher, thus make in operation more simple and convenient.
In addition, in actual applications, the digital signature information in Quick Response Code can be the digest algorithm based on symmetric key, such as adopts MD5 digest algorithm, digital signature information=MD5 (user name+current time+random number+user cipher) in Quick Response Code;
In addition, if when realizing in order to improve security, digital signature information also can adopt the mode of unsymmetrical key (PKI), the summary of the encrypted private key MD5 of user (user name+current time+random number) is used to obtain digital signature information in Quick Response Code, then monitoring camera pusher side uses the PKI of user to verify this digital signature information, if be proved to be successful, then opening gate, monitoring camera pusher side can be avoided to preserve user cipher by the mode of this unsymmetrical key, and the checking only needing the PKI of user can realize digital signature information in Quick Response Code, improve security.
Can be found out by foregoing description, the present invention passes through at monitoring camera pusher side integrated two-dimensional code scan function, at smart machine (such as mobile phone) the side integrated two-dimensional code systematic function of user, and in the mode of carrying the Quick Response Code of user's ID authentication information that CCTV camera scanning user mobile phone application program generates, carry out the true and false of identifying user identity, and when identifying user identity passes through just opening gate, thus make the unlatching of gate inhibition safer.
