Fig. 3 is the flow chart of the statistical method of a kind of client number of users according to another exemplary embodiment, and the present embodiment illustrates in the terminal 110 of implementation environment shown in Fig. 1 with the Application of Statistic Methods of this client number of users.The statistical method of this client number of users can comprise following several step:

Step 301, is accorded with by identifier code generating identification.

Step 302, encrypted identifier obtains encrypted identifier.

Step 303, is sent to server by encrypted identifier, and server is used for the number of users according to encrypted identifier statistics client.

Fig. 4 is the flow chart of the statistical method of a kind of client number of users according to another exemplary embodiment, and the present embodiment illustrates in implementation environment shown in Fig. 1 with the Application of Statistic Methods of this client number of users.The statistical method of this client number of users can comprise following several step:

Step 401, user end to server sends statistics request.

When needing the statistics of carrying out client number of users, client can send statistics request to server.Optionally, client is before sending statistics request to server, first can detect in the terminal of running client and whether store statistics mark, statistics is designated and feeds back to client after the serviced device of client counts client number of users, when not storing statistics mark in the terminal, user end to server sends statistics request, does not send statistics request when storing statistics mark in the terminal to server.

Exemplary, client can all detect in the terminal of running client whether store statistics mark when each startup, more according to circumstances determines whether send statistics request to server.

It should be noted that, client after operation predetermined time period, then can send statistics request, to increase the validity of statistics to server.

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

Server, after the statistics request receiving client transmission, can send identifier code to client.The generating mode of identifier is included in identifier code.Wherein, can comprise more than one identifier code in server, server sends to the identifier code of different clients may not be identical.Optionally, the timestamp recording identifier code delivery time together can be sent to client with identifier code by server.

Step 403, the identifier code that client reception server sends.

Step 404, client by identifier code obtain at least n kind unique identification corresponding with active client and at least n kind uniquely identified put in order, unique identification has m kind, m>n, and when m is odd number, n=(m+1)/2, when m is even number, n=m/2+1.

Client is after the identifier code receiving server transmission, identifier code can be resolved, and the acquisition at least n kind unique identification corresponding with active client and at least n kind uniquely identified put in order, unique identification has m kind, m>n, and when m is odd number, n=(m+1)/2, when m is even number, n=m/2+1.Wherein, unique identification can be the unique mark corresponding with client or terminal.

It should be noted that, unique identification is not included in identifier code, but include putting in order between the generating identification symbol uniquely identified kind of needs and unique identification, namely identifier code can regulation generating identification symbol need uniquely identified kind and uniquely identified put in order, this step shows a kind of possible prescribed manner of identifier code.Optionally, identifier code can also have other prescribed manner, a kind of unique identification in such as regulation m kind unique identification is directly as identifier, or regulation m kind unique identification all arranges in a predetermined order as identifier, the wherein uniquely identified that the use sum of m for arranging between client and server.

Exemplary, unique identification can comprise MAC (the Media AccessControl of the terminal of running client, 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.

Step 405, client is according at least n kind unique identification and the generating identification that puts in order accord with.

Client obtaining after at least n kind unique identification and uniquely identified put in order, can to put in order generating identification symbol according at least n kind unique identification and uniquely identified.

Exemplary, client obtains MAC Address " X ", the CPUID " Y " and GUID " Z " of the terminal of running client according to identifier code, and these 3 kinds of uniquely identifieds put in order as GUID-MAC address-CPUID, then the identifier that client generates is " ZXY ".

It should be noted that, client is according at least n kind unique identification generating identification symbol, and unique identification has m kind, m>n, when m is odd number, n=(m+1)/2, when m is even number, n=m/2+1, can ensure in the more than one identifier that same client generates according to different identifier code, have at least a unique identification to be identical in any two identifiers, not only decrease the data volume needing to send, and ensure that the execution of deduplication process of server.

Step 406, client encrypt identifier obtains encrypted identifier.

Client, after generating identification symbol, can obtain encrypted identifier to identifier encryption.

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

1) client is when using symmetry encryption technology to be encrypted identifier, need to prestore the symmetric key with server commitment in client, use this symmetric key to be encrypted identifier afterwards and obtain encrypted identifier, server can obtain identifier by symmetric key decryption encrypted identifier afterwards.

2) client is when using unsymmetrical tridiagonal matrix technology to be encrypted identifier, first the PKI of server can be obtained, such as, PKI and identifier code together can be sent to client by server in step 402, client is after acquisition PKI, can obtain encrypted identifier by this PKI to identifier encryption, server then can be carried out enabling decryption of encrypted identifier and obtain identifier by the private key that PKI is corresponding.

Step 407, client generates redundant information according to preset algorithm, and preset algorithm is the algorithm of making an appointment with server.

Client can generate redundant information according to preset algorithm, and preset algorithm can be the algorithm that client and server are made an appointment.Possible preset algorithm is: the length being redundant information with at least one bit value preset in encrypted identifier and the product of identifier code, the content of stochastic generation redundant information, obtains redundant information.Exemplary, can the product of first place when encrypted identifier represents with 16 systems and the identifier code length that is redundant information, the content of stochastic generation redundant information, obtains redundant information afterwards.

It should be noted that, this step only needs to perform after step 403, and namely client can generate redundant information after receiving the identifier code of server transmission.

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

Client generation redundant information after, before or after redundant information can being attached to encrypted identifier.It should be noted that, can decide according to the algorithm of the redundant information with server commitment before or after redundant information being attached to encrypted identifier, exemplary, when in preset algorithm with encrypted identifier at least one bit value of presetting and the product of the identifier code length that is redundant information time, can using the predetermined manner of default at least one bit value as basis for estimation, when such as this at least one bit value preset is encrypted identifier the first, after redundant information can being attached to encrypted identifier, enable server eliminate redundancy information.

It should be noted that, redundant information can change client and send to the length of the encrypted identifier of server and the structure of encrypted identifier, the malicious user of the data of server can be sent to play the effect of interference to intercepting client, add the fail safe of encrypted identifier, improve the reliability of the client number of users of server statistics.

Step 409, redundant information is sent to server by client together with encrypted identifier.

Redundant information is being attached to after before or after encrypted identifier by client, redundant information can be sent to server together with encrypted identifier.Optionally, client receive server send record the timestamp of identifier code delivery time time, this timestamp also together can be sent to server.

Step 410, the encrypted identifier being accompanied with redundant information that server receives client sends, redundant information is that client generates according to preset algorithm, and preset algorithm is the algorithm of making an appointment with client.

The encrypted identifier being accompanied with redundant information that server receives client sends, optionally, when the timestamp recording identifier code delivery time is together sent to server with the encrypted identifier being accompanied with redundant information by client, server can check this timestamp, the time interval between the moment that the moment of recording in this timestamp and server receive this timestamp is not when exceeding prefixed time interval, perform step 411, the time interval between the moment that the moment of recording in this timestamp and server receive this timestamp is when exceeding prefixed time interval, the encrypted identifier being accompanied with redundant information received can be discarded as time-out information, can reduce the encrypted identifier being accompanied with redundant information is like this possibility that malicious user is forged.

Step 411, server obtains encrypted identifier according to preset algorithm eliminate redundancy information.

Server receive client send be accompanied with the encrypted identifier of redundant information after, encrypted identifier can be obtained according to preset algorithm eliminate redundancy information.

Step 412, server encrypted identifier be client by during public key encryption, check the length of encrypted identifier.

Ciphertext length due to public key encryption always equals the integral multiple of PKI length, thus be that client is by during public key encryption at encrypted identifier, server can check the length of encrypted identifier, and judges that whether encrypted identifier is the identifier of the public key encryption that server is corresponding by the length of encrypted identifier.

When the length of encrypted identifier is the integral multiple of the length of PKI, perform step 413, when the length of encrypted identifier is not the integral multiple of length of PKI, this encrypted identifier abandons by server.

Step 413, when the length of encrypted identifier is the integral multiple of the length of PKI, server enabling decryption of encrypted identifier obtains identifier.

When the length of encrypted identifier is the integral multiple of the length of PKI, shows that this encrypted identifier is by public key encryption corresponding to server, can be decrypted this encrypted identifier by corresponding private key afterwards.

It should be noted that, server can generate PKI and the private key of more than one group every designated time interval, and provide different PKIs to client, in this case, client needs the PKI used when encrypting identifier also to send to server, so that server is decrypted by corresponding private key pair encryption identifier.

Also it should be noted that, amount of calculation during owing to being decrypted by private key is comparatively large, and thus server is only that the encrypted identifier of the integral multiple of PKI is decrypted to length, reduces the deciphering amount of calculation of server.

Also it should be noted that, when encrypted identifier is accompanied with redundant information, even if malicious user obtains the redundant information that PKI also cannot generate correct length, then cannot by the inspection of server to the length of encrypted identifier.

Step 414, server carries out deduplication process by the history identification symbol stored to identifier.

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

1) server parses identifier, obtain at least n kind unique identification corresponding with client, unique identification has m kind, m>n, and when m is odd number, n=(m+1)/2, when m is even number, n=m/2+1.

2) whether server detects in the history identification symbol stored and includes and any one the consistent unique identification at least n kind unique identification, the identifier of history identification symbol for storing before this.

3) if history identification symbol includes and any one the consistent unique identification at least n kind unique identification, then identifier abandons by server.

Exemplary, this obtains MAC Address " X ", CPUID " Y " and GUID " Z " after resolving identifier, and include CPUID " Y " and hard disk serial number " P " in having a history identification to accord with in the history identification symbol of server stores, identifier accords with history identification has identical CPUID, and thus server can abandon this identifier.

Step 415, server verifies identifier by identifier code.

Encrypted identifier is being deciphered by server, and after obtaining identifier, whether the uniquely identified kind that can detect in identifier is consistent with identifier code with order.Server to all clients provide be all same identifier code time, identifier code is herein this kind of identifier code, when server provides multiple identifier code to client, identifier code herein can be that client is sent to server with the encrypted identifier being accompanied with redundant information.

It should be noted that, identifier code also can think data of encrypting, and only has server and client side to decipher and obtain the information wherein comprised.

Step 416, server is when identifier passes through the checking of identifier code, and location identifier, identifier code is for verifying identifier.

Server is when identifier is by the checking of identifier code, and location identifier, the identifier of storage can coordinate when obtaining identifier afterwards as history identification symbol and carries out deduplication process.

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 stored.

Server is after storing identifier, and can add up the total quantity of the identifier of storage, this total quantity can as the number of users of client.

Optionally, server, after the number of users of statistics client, can send statistics mark to client, represent and this client is counted client number of users.

It should be added that, the statistical method of the client number of users that the embodiment of the present invention provides, by giving encrypted identifier affix redundant information, the malicious user of the data of server is sent to play the effect of interference to intercepting client, reach the fail safe increasing encrypted identifier, improve the effect of the reliability of the client number of users of server statistics.

It should be added that, the statistical method of the client number of users that the embodiment of the present invention provides, is only that the encrypted identifier of the integral multiple of PKI is decrypted to length by server, reaches the effect of the deciphering amount of calculation reducing server.

It should be added that, the statistical method of the client number of users that the embodiment of the present invention provides, by client according at least n kind unique identification generating identification symbol, and unique identification has m kind, m>n, when m is odd number, n=(m+1)/2, when m is even number, n=m/2+1, in the more than one identifier that same client is generated according to different identifier code, a unique identification is had at least to be identical in any two identifiers, reach the data volume not only reducing and need to send, and the effect of the execution of Deterministic service device deduplication process.

Fig. 5 is the flow chart of the statistical method of a kind of client number of users according to an exemplary embodiment, and the present embodiment illustrates in implementation environment shown in Fig. 1 with the Application of Statistic Methods of this client number of users.The statistical method of this client number of users can comprise following several step:

Step 501, client detects whether store statistics mark.

Client is when carrying out the demographics of client, first can detect and whether store statistics mark, statistics is designated and feeds back to client after the serviced device of client counts client number of users, when not storing statistics mark in the terminal, client can send statistics request to server, does not send statistics request when storing statistics mark in the terminal to server.Exemplary, client can all detect in the terminal of client operation whether store statistics mark when each startup.Optionally, statistics mark can be stored in registration table by client, to increase the reliability of statistics mark.

Step 502, client, when not storing statistics mark, accords with according to identifier code generating identification.

Client is not when storing statistics mark, and can accord with according to identifier code generating identification, wherein, identifier code for being pre-stored within client, such as when client is installed on terminal, just can obtain identifier code from installation kit.And 2 sub-steps below can be divided into according to identifier code generating identification symbol:

1) client by identifier code obtain at least n kind unique identification corresponding with active client and at least n kind uniquely identified put in order, unique identification has m kind, m>n, and when m is odd number, n=(m+1)/2, when m is even number, n=m/2+1.Exemplary, unique identification can comprise MAC (the Media Access Control of the terminal that client is run, 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 kind unique identification and the generating identification that puts in order accord with.Client, can according at least n kind unique identification and the generating identification symbol that puts in order obtaining after at least n kind unique identification and various uniquely identified put in order.Exemplary, client obtains MAC Address " X ", the CPUID " Y " and GUID " Z " of the terminal that client is run according to identifier code, and these 3 kinds of uniquely identifieds put in order as GUID-MAC address-CPUID, then the identifier that client generates is " ZXY ".

It should be noted that, client is according at least n kind unique identification generating identification symbol, and unique identification has m kind, m>n, when m is odd number, n=(m+1)/2, when m is even number, n=m/2+1, can ensure in the more than one identifier that same client generates according to different identifier code, have at least a unique identification to be identical in any two identifiers, convenient service device carries out deduplication process.

Step 503, identifier is encrypted by client, obtains encrypted identifier.

Client, after generating identification symbol, can obtain encrypted identifier to identifier encryption.Optionally, client can be encrypted identifier by symmetry encryption technology or unsymmetrical tridiagonal matrix technology:

1) client is when using symmetry encryption technology to be encrypted identifier, need to prestore the symmetric key with server commitment in client, client uses this symmetric key to be encrypted identifier and obtains encrypted identifier afterwards, and server can obtain identifier by symmetric key decryption encrypted identifier afterwards.

2) client is when using unsymmetrical tridiagonal matrix technology to be encrypted identifier, first the PKI of server can be obtained, such as, client can prestore the PKI of server, or client can pass through CA (Certificate Authority, certificate management authority) obtain the PKI of server, client is after acquisition PKI, can obtain encrypted identifier by this PKI to identifier encryption, server then can be carried out enabling decryption of encrypted identifier and obtain identifier by the private key that PKI is corresponding.

Step 504, encrypted identifier is sent to server by client.

Encrypted identifier, after obtaining encrypted identifier, can be sent to server by client.Different clients use be different identifier code time, identifier code also can be sent to server by client in the lump.

Step 505, server receives encrypted identifier.

Step 506, server enabling decryption of encrypted identifier obtains identifier.

Server is after reception encrypted identifier, according to circumstances can obtain identifier by enabling decryption of encrypted identifier, such as, when client is by symmetric key encryption identifier, then server carrys out enabling decryption of encrypted identifier by the symmetric key of arranging with client prestored, when client is by public key encryption identifier, then server carrys out enabling decryption of encrypted identifier by the private key that PKI is corresponding.

Step 507, server carries out deduplication process by the history identification symbol stored to identifier.

Server can carry out deduplication process to identifier after obtaining identifier.

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

Step 508, server verifies identifier by identifier code.

Server, being deciphered by encrypted identifier, after obtaining identifier, can resolve identifier, and whether the uniquely identified kind detected in identifier is consistent with identifier code with order.Server to all clients provide be all same identifier code time, identifier code is herein this kind of identifier code, when server provides multiple identifier code to client, identifier code herein can be that client is sent to server with the encrypted identifier being accompanied with redundant information.

It should be noted that, identifier code also can think a file encrypted, and only has server and client side to decipher and obtain the information wherein comprised.
