Step 301, identifier is generated by identifier code.

Step 302, encrypted identifier obtains encrypted identifier.

Step 303, encrypted identifier is sent to server, server is used to count client according to encrypted identifier Number of users.

Fig. 4 is a kind of flow chart of the statistical method of client number of users according to another exemplary embodiment, The present embodiment is illustrated with the Application of Statistic Methods of the client number of users in implementation environment shown in Fig. 1.The client The statistical method of end number of users can include the following steps：

Step 401, user end to server sends statistics request.

When needing to carry out the statistics of client number of users, client can send statistics request to server.It is optional , client can first detect in the terminal of operation client whether be stored with system before statistics request is sent to server Meter mark, statistics, which is identified as after client being serviced device is included in client number of users, feeds back to client, in the terminal not When being stored with statistics mark, user end to server sends statistics request, not to service when being stored with statistics mark in the terminal Device sends statistics request.

Exemplary, whether it is stored with statistics in the terminal that client can all detect operation client in each start Mark, decide whether to send statistics request to server further according to situation.

It should be noted that client can send statistics request in operation predetermined time period and then to server, To increase the validity of statistical result.

Step 402, server sends identifier code according to statistics request to client.

Server can send identifier code after the statistics request of client transmission is received to client.Mark Include the generating mode of identifier in symbol coding.Wherein, more than one identifier code can be included in server, is serviced The identifier code that device is sent to different clients may and differ.Optionally, record can be had identifier by server The timestamp of coding delivery time is together sent to client with identifier code.

Step 403, the identifier code that client the reception server is sent.

Step 404, client obtains corresponding with active client at least n kinds unique mark and extremely by identifier code Few n kind unique marks put in order, and unique mark shares m kinds, m>N, and n=(m+1)/2, be even in m when m is odd number During number, n=m/2+1.

Client can parse identifier code after the identifier code of server transmission is received, and obtain and work as At least n kinds unique mark and at least n kinds unique mark puts in order corresponding to preceding client, and unique mark shares m kinds, m>N, And when m is odd number, n=(m+1)/2, when m is even number, n=m/2+1.Wherein, unique mark can be and client or end Uniquely identified corresponding to end.

It should be noted that not including unique mark in identifier code, but include generation identifier needs Unique mark species and unique mark between put in order, i.e., identifier code can specify that generation identifier needs The species of unique mark and putting in order for unique mark, this step show a kind of possible regulation side of identifier code Formula.Optionally, identifier code can also have the unique mark of one kind in other prescribed manners, such as regulation m kind unique marks Know directly as identifier, or all arrangement is used as identifier to regulation m kinds unique mark in a predetermined order, wherein m is client The sum for the used unique mark arranged between server.

Exemplary, the MAC that unique mark can include the terminal of operation client (Media AccessControl, is situated between Matter access control) address, CPUID (Central Processing Unit ID, central processing unit sequence number), GUID (Globally Unique Identifier, GUID) and hard disk serial number etc..

Step 405, client is according at least n kinds unique mark and the generation identifier that puts in order.

Client, can be according at least n kinds after the putting in order of at least n kinds unique mark and unique mark is obtained The generation identifier that puts in order of unique mark and unique mark.

Exemplary, client obtains MAC Address " X ", the CPUID of the terminal of operation client according to identifier code " Y " and GUID " Z ", and this 3 kinds of unique marks put in order as GUID-MAC addresses-CPUID, the then mark of client generation Accord with as " ZXY ".

It should be noted that client generates identifier according at least n kinds unique mark, and unique mark shares m kinds, m> N, when m is odd number, n=(m+1)/2, when m is even number, n=m/2+1, it is ensured that same client is according to different In the more than one identifier of identifier code generation, at least one unique mark is identical in any two identifier , not only reduce the data volume that needs are sent, and ensure that the execution of the deduplication processing of server.

Step 406, client encrypted identifier obtains encrypted identifier.

Client can encrypt to obtain encrypted identifier after identifier is generated to identifier.

Client identifier can be encrypted by symmetry encryption technology or unsymmetrical tridiagonal matrix technology：

1) client is needed to prestore and taken when identifier is encrypted using symmetry encryption technology in client The symmetric key for device agreement of being engaged in, is encrypted to obtain encrypted identifier to identifier, takes afterwards using the symmetric key afterwards Business device can obtain identifier by symmetric key decryption encrypted identifier.

2) client can obtain server first when identifier is encrypted using unsymmetrical tridiagonal matrix technology Public key, such as, public key and identifier code can be together sent to client by server in step 402, and client is obtaining After taking public key, identifier can be encrypted by the public key to obtain encrypted identifier, server then can be by corresponding to public key Private key obtains identifier to decrypt encrypted identifier.

Step 407, client generates redundancy according to preset algorithm, and preset algorithm is the calculation made an appointment with server Method.

Client can generate redundancy according to preset algorithm, and preset algorithm can be that client and server are advance The algorithm of agreement.A kind of possible preset algorithm is：With default at least one digit number value and identifier code in encrypted identifier Product be redundancy length, the random content for generating redundancy, obtain redundancy.Exemplary, it can add The product of first place and identifier code when close identifier is represented using 16 systems generates superfluous at random afterwards as the length of redundancy The content of remaining information, obtains redundancy.

It should be noted that this step only needs to perform after step 403, i.e., client receives server hair Redundancy can be generated after the identifier code sent.

Step 408, redundancy is attached to before or after encrypted identifier by client.

Redundancy can be attached to before or after encrypted identifier by client after redundancy is generated.Need Can be according to the redundancy with server commitment before or after encrypted identifier it is noted that redundancy is attached to Algorithm determine, it is exemplary, when in preset algorithm with encrypted identifier in default at least one digit number value compiled with identifier When the product of code is the length of redundancy, can using the predetermined manner of default at least one digit number value as basis for estimation, than Such as the default at least one digit number value be encrypted identifier first place when, redundancy can be attached to encrypted identifier it Afterwards, enable the server to reject redundancy.

It should be noted that redundancy can change client be sent to server encrypted identifier length and The structure of encrypted identifier, the malicious user for the data that can be sent to server to interception client play a part of interference, The security of encrypted identifier is added, improves the reliability of the client number of users of server statistics.

Step 409, client sends redundancy and encrypted identifier to server together.

Client, can be by redundancy and encryption after before or after redundancy is attached into encrypted identifier Identifier is sent to server together.Optionally, the record for receiving server transmission in client has identifier code transmission During the timestamp at moment, the timestamp also can be together sent to server.

Step 410, server receives the encrypted identifier for being accompanied with redundancy that client is sent, and redundancy is visitor Family end generates according to preset algorithm, and preset algorithm is the algorithm made an appointment with client.

Server receives the encrypted identifier for being accompanied with redundancy that client is sent, and optionally, will remember in client When the timestamp that record has identifier code delivery time is together sent to server with being accompanied with the encrypted identifier of redundancy, Server can check the timestamp, at the time of record in the timestamp and at the time of server receives the timestamp between Time interval not less than prefixed time interval when, perform step 411, in the timestamp record at the time of with server receive When time interval between at the time of the timestamp exceedes prefixed time interval, redundancy can be accompanied with by what is received Encrypted identifier discarded as time-out information, can so reduce be accompanied with redundancy encrypted identifier be malice use The possibility that family is forged.

Step 411, server rejects redundancy according to preset algorithm and obtains encrypted identifier.

Server receive client transmission be accompanied with the encrypted identifier of redundancy after, can be according to pre- imputation Method rejects redundancy and obtains encrypted identifier.

Step 412, server checks the length of encrypted identifier when encrypted identifier is client by public key encryption Degree.

It is client because the ciphertext length of public key encryption is always equal to the integral multiple of public key length, thus in encrypted identifier End by public key encryption when, server can check the length of encrypted identifier, and be sentenced by the length of encrypted identifier Disconnected encrypted identifier whether be public key encryption corresponding to server identifier.

When the length of encrypted identifier is the integral multiple of length of public key, step 413 is performed, in the length of encrypted identifier When degree is not the integral multiple of length of public key, server abandons the encrypted identifier.

Step 413, when the length of encrypted identifier is the integral multiple of length of public key, server decryption encrypted identifier Obtain identifier.

When the length of encrypted identifier is the integral multiple of length of public key, show the encrypted identifier to pass through server Corresponding public key encryption, the encrypted identifier can be decrypted by corresponding private key afterwards.

It should be noted that server can generate more than one group of public key and private key every designated time interval, and to Client provides different public keys, and in this case, client needs also to send the public key used when encrypting identifier To server, in order to which server is decrypted by corresponding private key pair encryption identifier.

It should also be noted that, amount of calculation during due to being decrypted by private key is larger, thus server is only to length It is that the encrypted identifier of the integral multiple of public key is decrypted, reduces the decryption amount of calculation of server.

It should also be noted that, when encrypted identifier is accompanied with redundancy, malicious user is even if obtaining public key The redundancy of correct length can not be generated, can not then pass through inspection of the server to the length of encrypted identifier.

Step 414, server carries out deduplication processing by the history identification symbol of storage to identifier.

This step can be divided into following 3 sub-steps：

1) server parsing identifier, at least n kind unique marks corresponding with client being obtained, unique mark shares m kinds, m>N, and when m is odd number, n=(m+1)/2, when m is even number, n=m/2+1.

2) whether include and at least any of n kinds unique mark one in the history identification symbol of server detection storage The unique mark of cause, the identifier that history identification symbol stores before for this.

If 3) history identification symbol include with least consistent unique mark of any of n kinds unique mark, service Device abandons identifier.

It is exemplary, obtain MAC Address " X ", CPUID " Y " and GUID " Z " after this parsing identifier, and server Have in the history identification symbol of storage in a history identification symbol and include CPUID " Y " and hard disk serial number " P ", identifier is with going through History identifier has identical CPUID, thus server can abandon the identifier.

Step 415, server verifies identifier by identifier code.

Server is decrypted by encrypted identifier, after obtaining identifier, can detect the kind of the unique mark in identifier Whether class and order are consistent with identifier code.What is provided in server to all clients is all same identifier code When, identifier code herein is this kind of identifier code, when server provides a variety of identifier codes to client, this The identifier code at place can be that client is sent to server with the encrypted identifier for being accompanied with redundancy.

It should be noted that identifier code is it is also assumed that be the data of an encryption, and only server and client The information wherein included can be decrypted and obtained in end.

Step 416, server stores identifier in checking of the identifier by identifier code, and identifier code is used In checking identifier.

Server stores identifier, the identifier of storage can conduct in checking of the identifier by identifier code History identification symbol coordinates when obtaining identifier afterwards carries out deduplication processing.

It should be noted that step 415 and step 416 can also perform before step 414.

Step 417, server is according to the number of users of the quantity statistics client of the identifier of storage.

Server can count the total quantity of the identifier of storage after identifier is stored, and this total quantity can be with Number of users as client.

Optionally, server can send statistics mark to client, represent after the number of users of statistics client The client is included in client number of users.

It should be added that the statistical method of client number of users provided in an embodiment of the present invention, by adding Close identifier affix redundancy, the malicious user for the data for being sent to server to interception client play the work of interference With having reached the security of increase encrypted identifier, improved the effect of the reliability of the client number of users of server statistics.

It should be added that the statistical method of client number of users provided in an embodiment of the present invention, passes through service Device is only that the encrypted identifier of the integral multiple of public key is decrypted to length, has reached the effect for the decryption amount of calculation for reducing server Fruit.

It should be added that the statistical method of client number of users provided in an embodiment of the present invention, passes through client End is according at least n kinds unique mark generation identifier, and unique mark shares m kinds, m>N, when m is odd number, n=(m+1)/2, When m is even number, n=m/2+1, the more than one identifier for making same client be generated according to different identifier codes In, at least one unique mark is identical in any two identifier, has reached and has not only reduced the data volume that needs are sent, And ensure the effect of the execution of server deduplication processing.

Fig. 5 is a kind of flow chart of the statistical method of client number of users according to an exemplary embodiment, this Embodiment is illustrated with the Application of Statistic Methods of the client number of users in implementation environment shown in Fig. 1.The client The statistical method of number of users can include the following steps：

Step 501, client detects whether to be stored with statistics mark.

Client can first detect whether to be stored with statistics mark, statistics mark when carrying out the demographics of client It is included in for client being serviced device after client number of users and feeds back to client, is not stored with statistics mark in the terminal When, client can send statistics request to server, do not send and count to server when being stored with statistics mark in the terminal Request.Exemplary, whether it is stored with statistics mark in the terminal that client can all detect client operation in each start Know.Optionally, statistics mark can be stored in registration table by client, and the reliability of mark is counted with increase.

Step 502, client generates identifier when not being stored with statistics mark according to identifier code.

Client can generate identifier when not being stored with statistics mark according to identifier code, wherein, identifier is compiled Code can be to be pre-stored within client, such as when client is installed on terminal, it is possible to mark is obtained from installation kit Know symbol coding.And following 2 sub-steps can be divided into by generating identifier according to identifier code：

1) client obtains at least n kinds unique mark corresponding with active client and at least n kinds by identifier code Unique mark puts in order, and unique mark shares m kinds, m>N, and when m is odd number, n=(m+1)/2, when m is even number, n =m/2+1.It is exemplary, unique mark can include the terminal of client operation MAC (Media Access Control, Medium access control) address, CPUID (Central Processing Unit ID, central processing unit sequence number), GUID (Globally Unique Identifier, GUID) and hard disk serial number etc..

2) client is according at least n kinds unique mark and the generation identifier that puts in order.Client is obtaining at least n kinds , can be according at least n kinds unique mark and the generation mark that puts in order after the putting in order of unique mark and various unique marks Know symbol.Exemplary, client obtains MAC Address " X ", the CPUID " Y " of the terminal of client operation according to identifier code With GUID " Z ", and this 3 kinds of unique marks put in order as GUID-MAC addresses-CPUID, then the identifier of client generation For " ZXY ".

It should be noted that client generates identifier according at least n kinds unique mark, and unique mark shares m kinds, m> N, when m is odd number, n=(m+1)/2, when m is even number, n=m/2+1, it is ensured that same client is according to different In the more than one identifier of identifier code generation, at least one unique mark is identical in any two identifier , facilitate server to carry out deduplication processing.

Step 503, client encrypts identifier, obtains encrypted identifier.

Client can encrypt to obtain encrypted identifier after identifier is generated to identifier.Optionally, client can be with Identifier is encrypted by symmetry encryption technology or unsymmetrical tridiagonal matrix technology：

1) client is needed to prestore and taken when identifier is encrypted using symmetry encryption technology in client Be engaged in device agreement symmetric key, afterwards client identifier is encrypted to obtain encrypted identifier using the symmetric key, Server can obtain identifier by symmetric key decryption encrypted identifier afterwards.

2) client can obtain server first when identifier is encrypted using unsymmetrical tridiagonal matrix technology Public key, such as, client can prestore the public key of server, or client can pass through CA (Certificate Authority, certificate management authority) obtain server public key, client after public key is obtained, can by the public key to mark Know symbol encryption and obtain encrypted identifier, server can then be identified by private key corresponding to public key to decrypt encrypted identifier Symbol.

Step 504, client sends encrypted identifier to server.

Client can send encrypted identifier to server after encrypted identifier is obtained.Make in different clients For different identifier codes when, client can also send identifier code to server in the lump.

Step 505, server receives encrypted identifier.

Step 506, server decryption encrypted identifier obtains identifier.

Server can according to circumstances decrypt encrypted identifier and obtain identifier after encrypted identifier is received, such as, When client is by symmetric key encryption identifier, then server is decrypted by the symmetric key arranged with client to prestore Encrypted identifier, when client is by public key encryption identifier, then server decrypts encryption by private key corresponding to public key Identifier.

Step 507, server carries out deduplication processing by the history identification symbol of storage to identifier.

Server can carry out deduplication processing after identifier is obtained to identifier.

This step can be divided into following 3 sub-steps：

Step 508, server verifies identifier by identifier code.

Server is decrypted by encrypted identifier, after obtaining identifier, can be parsed identifier, be detected in identifier only Whether the species and order of one mark are consistent with identifier code.What is provided in server to all clients is all same mark When knowing symbol coding, identifier code herein is this kind of identifier code, and a variety of identifiers are provided to client in server During coding, identifier code herein can be that client is sent to service with the encrypted identifier for being accompanied with redundancy Device.

It should be noted that identifier code is it is also assumed that be the file of an encryption, and only server and client The information wherein included can be decrypted and obtained in end.

Step 509, server stores identifier in checking of the identifier by identifier code, and identifier code is used In checking identifier.
