Embodiment
Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in more detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Fig. 1 shows a kind of according to an embodiment of the invention flow chart identifying the method for refuse messages.As shown in Figure 1, the method comprises:
Step S110, receives event to the note in mobile terminal and detects.
Step S120, when mobile terminal receives note, calculates the corresponding cryptographic Hash of content of this note.
Step S130, uploads to cloud server by cryptographic Hash corresponding for the content of note, and receives the identifying information that cloud server returns.
Whether step S140 is refuse messages according to identifying information determination note.
Visible, the method shown in Fig. 1 describes with cryptographic Hash corresponding to the content of note for identifying object from the angle of client, and client and cloud server carry out mutual process, achieve the identification to refuse messages.The method, on the basis ensureing refuse messages identification validity, avoids the problem of the infringement individual subscriber privacy of directly uploading onto the server caused by the content of note when agreeing to without user; And after the computing of this locality, alleviate the mutual burden of client and cloud server and the processing pressure of cloud server, improve recognition efficiency, meet user's request.
In one embodiment of the invention, the method shown in Fig. 1 comprises further:
Step S150, when determining that described note is refuse messages, carries out intercept process to described note.Here intercept process specifically can comprise: directly delete refuse messages; Or short for rubbish breath is transferred in the file of specifying, waits for the process of user; Or user is carried out to the prompting of refuse messages.
In one embodiment of the invention, cryptographic Hash corresponding to the content calculating this note described in step S120 refers to: according to certain traditional hash algorithm, be the numerical value of regular length by the content map of this note, this numerical value is called cryptographic Hash, this cryptographic Hash be the content of this note uniquely and extremely compact numeric representation form.
Hash algorithm described in the present embodiment comprises: HAVAL, MD2, MD4, MD5 or SHA1 etc., this quasi-tradition hash algorithm is all just like next essential characteristic: in input domain, seldom occur hash collision, namely for may gap only have the text of a byte also can map out two diverse cryptographic Hash.
Such as, the content of two swindle notes is respectively: " congratulations have suffered 50,000 yuan of Grand Prixs " and " congratulations have suffered 10,000 yuan of Grand Prixs ", and the corresponding cryptographic Hash of content being calculated these two notes by traditional hash algorithm is respectively 286 and 523.Can see, the cryptographic Hash that the closely similar note of two fraud tactics calculates is completely different, and the identification pressure of cloud server in subsequent treatment may be caused excessive.
Therefore, in order to the deviation between the corresponding cryptographic Hash of the content removing the note of difference among a small circle, alleviate the identification pressure of cloud server in subsequent treatment, in another embodiment of the present invention, the corresponding cryptographic Hash of the content calculating this note described in step S120 refers to: calculate the simhash value that the content of this note is corresponding.Detailed process is as follows:
Step S121, carries out word segmentation processing to the content of note.
Step S122, gives different vector value to each word after participle, gathers the simhash value that the content that calculates note is corresponding.
For table 1 and table 2, the solution of the present invention is described in detail below.
Table 1
Table 2
Table 1 shows the process according to simhash value corresponding to the content of the present invention's specific embodiment calculating note.As shown in table 1, in the present embodiment, the note that mobile terminal receives is: " our company opens common invoice in generation, and generation does not open VAT invoice and professional invoice in our company.”
First, the vector form that initialization simhash value is corresponding: A=A
o={ 0,0,0,0,0,0}.
Then, word segmentation processing is carried out to the content of this note: our company/generation opens/common/invoice/, our company/or not generation opens/value-added tax/special/invoice/and/specialty/invoice; Obtaining each word after participle is: our company, Dai Kai, or not value-added tax, special, invoice, common, and, specialty.
According to certain traditional hash algorithm, calculate 6 cryptographic Hash that each word is corresponding respectively: our company: 100110, Dai Kai: 110000, no: 101111, value-added tax: 110001, special: 010110, invoice: 101011, common: 110100, and: 110110, specialty: 001001.
Calculate the vector value of word frequency as correspondence of each word again, represent the weight of each word in short message content: our company: 2, Dai Kai: 2, no: 1, value-added tax: 1, special: 1, invoice: 3, common: 1, and: 1, specialty: 1.
Forming vectorial B:{ our company/100110/2, generation opens/and 110000/2, no/101111/1, value-added tax/110001/1, special/010110/1, invoice/101011/3, common/110100/1, and/110110/1, specialty/001001/1}.
Process each word in vectorial B successively, processing mode is as follows: for each word, if i-th of its cryptographic Hash is " 1 ", then i-th dimension of vectorial A is added to the word frequency of this word; If i-th of its cryptographic Hash is " 0 ", then i-th dimension of vectorial A is deducted to the word frequency of this word.Such as, for our company/100110/2, vectorial A becomes { 2 ,-2 ,-2,2,2 ,-2}; For generation open/110000/2, vectorial A becomes { 2,2 ,-2 ,-2 ,-2 ,-2}; By that analogy, obtain the vectorial A that each word is corresponding, as shown in table 1.
Vectorial A corresponding for each word is carried out gathering summation, obtains vectorial A
total=9 ,-1 ,-3,1,5,1}, if the i-th dimension of this vector is negative, then make the i-th dimension of the corresponding vector of simhash value be " 1 "; If the i-th dimension of this vector is negative, then the i-th dimension of the corresponding vector of simhash value is made to be " 0 "; Obtain the corresponding vectorial A of final simhash value accordingly
final={ 1,0,0,1,1,1}.
Therefore, " our company opens common invoice in generation to note, and generation does not open VAT invoice and professional invoice in our company." simhash value be 100111.
Table 2 shows the process according to simhash value corresponding to the content of another specific embodiment of the present invention calculating note.As shown in table 2, in the present embodiment, the note that mobile terminal receives is: " our company opens common invoice in generation, and generation does not open special invoice and professional invoice in our company." computational process of its simhash value in like manner in table 1, do not repeat them here.Can see, illustrate in table 2 and obtained vectorial A after gathering summation
total=8 ,-2 ,-2,0,6,0}, obtain the corresponding vectorial A of final simhash value
final={ 1,0,0,1,1,1}.Therefore, " our company opens common invoice in generation to note, and generation does not open special invoice and professional invoice in our company." simhash value be 100111, with note our company generation open common invoice, our company not generation open VAT invoice and professional invoice." simhash value identical.
From the above, in the computational process of simhash value, on the basis keeping each word weight, ignore the concrete size of the cryptographic Hash of each word gradually, but distinguish each word with the positive and negative of value after being gathered summation, and often similar short message content can obtain the identical summation vector A of symbol with its similar text structure
total, therefore, similar note can have identical simhash value, overcomes the hash problem of traditional hash algorithm.
In other embodiments of the invention, vector value can be given to each word after participle by other means.
In one embodiment of the invention, in order to improve the recognition efficiency of refuse messages further, the method shown in Fig. 1 comprises further: when mobile terminal receives note, first judges whether this note is white note according to the home town ruling of mobile terminal; If not, then perform the previously described corresponding cryptographic Hash of content calculating this note, and cryptographic Hash corresponding for the content of this note is uploaded to the subsequent treatment of cloud server; If so, then determine that this note is not refuse messages, no longer carry out follow-up process.

Scheme 2, carry out word segmentation processing in mobile terminal this locality to the content of note, each word after utilizing bayesian algorithm to calculate participle belongs to the probability of white note, gathers and calculates the probability that this note is white note, judge whether this probability is greater than a preset value, is, this note is white note.
Particularly, for each word after participle, the Feature Words mated with this word can be searched in the Bayesian model of training in advance, and obtain forward weighted value and the negative sense weighted value of this Feature Words, forward weighted value belongs to the probability of white note as this word, and negative sense weighted value does not belong to the probability of white note as this word; Gather according to the probability belonging to white note of each word after participle and calculate the probability that note is white note, gather according to the probability not belonging to white note of each word after participle and calculate the probability that note is not white note, if to be the probability of white note comparatively large and when exceeding preset value, then this note is white note for this note.Wherein, gather computational methods comprise the weighted value of the probability of each word adding and or weighted product, the present embodiment does not limit.
Scheme 3, in the local cryptographic Hash corresponding according to the content of above described method calculating note of mobile terminal, judging cryptographic Hash corresponding to the content of this note whether in cryptographic Hash white list according to the cryptographic Hash white list of mobile terminal this locality again, is that this note is white note.Wherein, this cryptographic Hash white list is arranged by mobile terminal this locality, or be issued to mobile terminal this locality by cloud server, further, cloud server can upgrade the cryptographic Hash white list of mobile terminal this locality at regular intervals.Wherein, the cryptographic Hash described in this programme is traditional cryptographic Hash or simhash value, owing to have recorded more cryptographic Hash in traditional cryptographic Hash white list, the mobile terminal that applicable capacity is larger.
