Describe the application in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that do not conflicting
In the case of, the feature in embodiment and embodiment in the application can be mutually combined.
A kind of data safety processing method of law-enforcing recorder is provided in the present embodiment, can be applied to law enforcement record
Instrument side, the file that can to record in law-enforcing recorder is by the way that, more for legal effect, the sound being signed regards after digital signature
The files such as frequency have non repudiation, as shown in Figure 1, this method includes：
101st, law-enforcing recorder obtains the corresponding law-executor's information of law-enforcing recorder.
Wherein, identity information of law-executor's information comprising law enfrocement official, unit one belongs to's information, place urban information etc.；Body
Part information can include the information such as the policeman's numbering, ID number, name of law enfrocement official.
In the present embodiment, law enfrocement official needs before the operations such as law-enforcing recorder record audio, video are used for the first time
Personal information is registered, the identity information such as inputted according to law enfrocement official, unit one belongs to's information are registered.And for this reality
The executive agent for applying example can be the data safe processing device applied to law-enforcing recorder, specifically can be only fitted to law enforcement record
Instrument side, when receiving data safe processing instruction, first according to the log-on message of law enfrocement official, it is opposite to obtain law-enforcing recorder
The law-executor's information answered, then performs the process described in step 102 to 105.
102nd, according to law-executor's information of acquisition, Generate Certificate demand file.
Wherein, certificate request file (CSR, Cerificate Signing Request) can be the original of digital certificate
File, contains server info and law-executor's information, is issued using the certificate request file request server certificate center of issuing
Send out digital certificate corresponding.
For example, extracted from law-executor's information of acquisition the organization of law enfrocement official unit one belongs to, department of unit one belongs to,
City name where name or state name, unit are saved where unit belonging country name, unit, and obtain the server network of application digital certificate
Domain name of standing or procotol (IP, Internet Protocol) address etc., be then based on these information Generate Certificate request text
Part.
103rd, the digital certificate for carrying certificate request file is issued into request and is sent to server.
Further, so that server is digitally signed according to certificate request file and issues digital certificate.For example,
Server just generates CertPubKey file using its root certificate private key signature, i.e., in order to which law-enforcing recorder issues digital certificate.
Wherein, digital certificate is the e-file for public-key cryptography infrastructure, for proving public-key cryptography owner
Identity.This file contains public key information, owner's identity information (main body) and digital certificate authentication mechanism (publisher)
To the digital signature of this part of file, to ensure that the entire content of this file is correct., can such as owner relies on this file
Show identity to computer system or other users, so that other side is trusted and authorizes access or taken using some sensitive computers
Business.Computer system or other users can verify the content on digital certificate by certain program, including digital certificate whether
Whether expired, digital signature is effective, if trusting the mechanism signed and issued, it is possible to the key on digital certificate is trusted, with the key
Encryption is reliably communicated with owner.
The main benefit of one of them of digital certificate is the sensitivity number of owner during certification owner's identity
It can't be transmitted to according to (such as date of birth, ID card No.) in the computer system for asking for data person.Handed over by this data
Mold changing formula, the identity of owner's both susceptible of proof oneself, does not also have to excessively disclose personal data, to ensureing that computer service accesses both sides
It is all beneficial.People are by trusting the root certificate of digital certificate authentication mechanism and its making digital signature using public key encryption
The public key certificate of core hair, forms trust chain framework, in safe transmission layer protocol (TLS, Transport Layer
Security) realize and WWW hypertext transfer protocol (HTTP, Hypertext Transfer Protocol) and
Hyper text transfer security protocol (HTTPS, Hypertext Transfer Protocol Secure), in the simple of Email
Mail Transfer protocol (SMTP, Simple Mail Transfer Protocol) and the extension of plain text communication protocol
(STARTTLS) simultaneously extensive use is introduced.
Digital signature (also known as public key digital signature, English：Digital Signature) it is a kind of similar write on paper
Common physical signature, but used the technology in public key encryption field to realize, the method for differentiating digital information.One tricks
Word signature usually define two kinds of complementary computings, one be used for sign, another be used for verify, but the Electronic Signature in law article with
Digital signature, the meaning of representative simultaneously differ, and Electronic Signature is recognizing and confirm e-file signer identity, qualification and electricity
Subfile true and false person.And digital signature is then that it is encrypted with mathematical algorithm or other modes computing, Electronic Signature, meaning are just formed
Electronic Signature is just createed using digital signature.
Digital signature does not refer to signature being scanned into digital picture, or the signature obtained with touch pad, is less inscription.
The integrality of the file of digital signature is it is easily verified that (seal on the perforation, junction of the edges of two sheets of paper signature is not required, it is not required that person's handwriting reflects
It is fixed), and digital signature has non repudiation (i.e. non-repudiation), it is not necessary to which handwriting expert is verified.Digital signature should
The one-way function principle used with public key cryptography field.One-way function refers to that positive operation is very simple, and contrary operation
Extremely difficult function, such as large integer multiplication.This function often provides a kind of mathematical problem for being difficult to resolve or suspecting and be difficult to resolve.Mesh
Before, three suspection double linear problems of difficulty for solving that public key cryptography field possesses practicality are：Prime factorization, discrete logarithm and elliptic curve are asked
Topic.
104th, the digital certificate issued that server is sent is received.
Wherein, the content field of digital certificate, generally defers to the certificate of X.509 format specification, has following content, bag
Include：Version, sequence number, main body, publisher, the term of validity time started, the term of validity end time, public-key cryptography purposes, public-key cryptography,
Public-key cryptography fingerprint, digital signature, Digital Signature Algorithm, main body alias etc..
105th, according to the digital certificate received, the record file for needing to sign in law-enforcing recorder is signed.
Wherein, the files such as audio, word, video, picture can be included by recording file.
For example, to recorded in law-enforcing recorder audio, video, the signature of the needs such as picture file content summary info
It is digitally signed.
For the present embodiment, the audio that is recorded in law-enforcing recorder, video, the file such as picture are carried out using digital certificate
Digital signature, shows the corresponding law-executor's information of the law-enforcing recorder for recording these files, and then can will use law enforcement record
Law-executor's information of instrument carries out corresponding with the file recorded on law-enforcing recorder so that the file recorded in law-enforcing recorder passes through
More there is non repudiation for the file such as legal effect, the audio and video being signed after digital signature.At the same time by using this
Digital signature technology, has also used encryption method to record file, also solves and file is recorded in law-enforcing recorder easily by people
The problem of to distort, so as to improve the preciseness of legal argument.
Further, the refinement and extension as above-described embodiment embodiment, in order to illustrate above-mentioned implementation
The specific implementation process of example, the above method further include：While demand file is Generated Certificate, adding in preset algorithm storehouse is utilized
Decipherment algorithm, generates the local private key of law-enforcing recorder；Obtain the corresponding summary info of record file in law-enforcing recorder；Phase
Answer, step 105 can specifically include：According to the local private key of generation, the summary info got and the numeral card received
Book, the record file signed to needs are signed.
Wherein, can be provided in preset algorithm storehouse encryption, decryption, summary scheduling algorithm, specifically can by technical staff according to
Configuration is write in actual demand in advance.It is to use different keys to encrypt and decrypt in modern password system, that is, asymmetric
Cipher key cryptographic system, each communication party are required to two keys, i.e. public key and private key, this two keys can encryption and decryption each other.
Public key is disclosed, it is not necessary to maintains secrecy, and private key oneself is held by individual, and must keep properly and pay attention to maintaining secrecy.
For example, using the enciphering and deciphering algorithm in preset algorithm storehouse, while demand file is Generated Certificate, generation is corresponding
The local private key of law-enforcing recorder, the local private key need to back up after generation, to return to the numeral card issued in server
During book, it can be decrypted using the local private key and the digital certificate is installed, if local private key does not back up, server
The digital certificate issued cannot be installed successfully, it is necessary to regenerate local private key and certificate request file, then re-started
Digital certificate request flow.After the digital certificate successfully issued is installed, the digital certificate and local private key pair can be utilized
The summary info of the file content of the needs such as the audio that is recorded in law-enforcing recorder, video, picture signature is digitally signed, with
Just signature operation is realized.
It is right according to local private key, the summary info got and the digital certificate received of generation based on such scheme
The step of record file for needing to sign is signed, can specifically include：Will record file and summary info utilization
Local private key carries out private key encryption calculating, obtains the finger print information of record file；Referring next in finger print information and digital certificate
Public key, and combine law-executor's information and record the relevant information of file, the corresponding certificate signature file of output record file.
For the present embodiment, the fingerprint that digital certificate signs documents is to carry out private by recording file and its informative abstract
Key computations are drawn, and law-enforcing recorder private key and public key are locally to export and be stored in local, anyone does not know private key
Content, therefore, the local Summary file by private key signature of law-enforcing recorder can be with by the public key in the digital certificate issued
Prove that the record file is the file that law-enforcing recorder locally exports, anyone non-repudiation, and then law-enforcing recorder passes through
The certificate files such as the audio and video of this method signature provided in this embodiment have legal effect.
For the present embodiment, as the species of conceptual illustration, illustratively digital certificate, can specifically include：From label
Certificate, root certificate, intermediary's certificate, the certificate of authority, end entity certificate, TLS server certificates, asterisk wildcard certificate, TLS clients
Certificate etc., is specifically described below every class certificate concrete concept.
When self signed certificate for small range test the purpose of, user can also oneself generation digital certificate, but do not have
There is any reliable people signature, this self-signed certificate will not usually be trusted extensively, and it is soft that when use can be potentially encountered computer
The safety warning of part.
Root certificate is also a kind of self signed certificate, but is widely recognized as, be usually pre-installed in various softwares (including
Operating system, browser, email software etc.), as the starting point of trust chain, come from generally acknowledged reliable government bodies, software public affairs
Department etc., recognizes program just in different software widespread deployments from major software business man by rigorous core.Since deployment program complexity is taken
When, it is necessary to the mandate of administrative personnel and the core of mechanism status of a legal person are recognized, a root certificate term of validity may be up to more than 10 years.
Some enterprises, it is also possible to which voluntarily installation enterprises are from the root certificate signed in internal computer, to support the enterprise software of in-house network；
But these certificates may be widely recognized as, only it is applicable in enterprises.
It is client's grant a certificate that one vital task of intermediary's certificate, which is exactly, although the certification authority being widely recognized as all has gathered around
There is root certificate, corresponding private key can be used to sign other certificates, but because key management and administrative consideration, can generally sign in advance
Intermediary's certificate is sent out, just makees digital signing for client.The term of validity of intermediary's certificate can be short compared with root certificate, and may be to different classes of
Client there are different intermediary's certificates to make to divide the work.
The certificate of authority is also known as Attribute certificate, itself does not have public key, it is necessary to which being attached on an effective digital certificate just has
Meaning, its use are to confer to the power that related possessor signs and issues end entity certificate；In some cases, if only awarded in a short time
Give certificate agency to sign and issue power, the term of validity for the certificate that (shortening) mechanism holds in itself can not be changed.Such case, class
It is similar to someone and holds passport up to decade, and only by signing and issuing short-term entry visa, assign passport bearer's volume individually
Outer power.
End entity certificate, other will not be used as signing and issuing other certificates, end entity certificate all be can be described as, in reality
Disposed in software, to create encrypted tunnel when is applied.
TLS server certificates, server usually provide service on the internet in the form of domain name, main body in server certificate
Adopted name will be corresponding domain name, associated mechanisms title is then write on one column of tissue or unit.Server certificate (including
Public key) and private key can be installed on server (such as Apache), agreement encryption details when waiting client connection.Client it is soft
Part (such as browser) can run certification path verification algorithm to ensure safety, failing to the whether safe (example of encrypted tunnel certainly
As the principal name on certificate does not correspond to website domain name, server has used self signed certificate or Encryption Algorithm is not strong enough), may
User can be alerted.
Asterisk wildcard certificate, if before adopted name (or main body alias) column of main body is with asterisk wildcard in server certificate
Sew, then the certificate can be used under all subdomain names, be particularly suitable for compared with tool scale or the mechanism one equipped with multiple subnet stations
Secondary cross claims, and set is used for multiple servers；Even if future creates new subdomain name, can also apply mechanically.But asterisk wildcard is unavailable
In on extended authentication certificate.
TLS client certificates, sometimes, some TLS servers may be when creating encrypted tunnel, it is desirable to which client carries
For client certificate, to verify identity and control access rights.Client certificate includes e-mail address or personal name, and
It is not host name.But client certificate compare it is uncommon, since it is considered that technical threshold and cost factor, are usually all by servicing
Supplier verifies client identity, rather than relies on Third Party Authentication mechanism.It is often necessary to use the service of client certificate all
It is the enterprise software of in-house network, they can set up the inside root certificate of oneself, by the technical staff of enterprise in enterprises
Computer installs relative clients end certificate to use.In disclosed internet, most of websites be all using login password and
Cookie verifies user, rather than client certificate.
Wherein, the relation of root certificate (self signed certificate), intermediary's certificate and end entity (TLS server/customer ends) certificate
Figure can be as shown in Figure 2.
It is further, specific as the alternative embodiment of the application, step 103 based on above-mentioned per class digital certificate
It can include：According to the local condition of law-enforcing recorder, the type of the definite digital certificate for needing to ask；Then according to the needs
The type of the digital certificate of request, issues request by the digital certificate for carrying certificate request file and is sent to server, so that
Server is obtained to be digitally signed according to certificate request file and issue digital certificate corresponding with request type.And then it can examine
Consider the local condition of law-enforcing recorder, ask the digital certificate for being adapted to law-enforcing recorder itself usage type, and then can be real
The record file now accurately signed to needs is signed.
Above-mentioned implementation process is illustrated in law-enforcing recorder side, in order to illustrate the service interacted with law-enforcing recorder
Device side operates, and further, the embodiment of the present application provides the data safety processing method of another law-enforcing recorder, Ke Yiying
For server side, as shown in figure 3, this method includes：
201st, server receives the digital certificate that law-enforcing recorder is sent and issues request.
Wherein, digital certificate is issued in request and carries certificate request file.In the present embodiment, the certificate in server
Issue center, it is believed that be the issuer of authority, be known trust authority in system.
202nd, obtain certificate request file in include with the corresponding law-executor's information of law-enforcing recorder.
203rd, the law-executor's information that will be got, and the correspondence progress between law-executor's information and law-enforcing recorder
