Flow chart.As shown in figure 1, the method includes：
Step S110, receives from outside information, determines the information source and content of information；
Step S120, judges whether information is junk information according to information source, when information source judges to believe
When breath is not junk information, the content according to information judges whether information is junk information；
Step S130, will be judged as that the information of junk information determines by the content of information source or information
It is junk information.
In the present invention, to include but is not limited to short message, instant communication information etc. conventional or unconventional for information
Information.Information source includes but is not limited to cell-phone number, Information ID etc. can be originated with beacon information
Identifier.Without loss of generality and for convenience of description, hereinafter few examples are substituted with short message
Information, cell-phone number alternative information source illustrate.It should be appreciated that this is only used for explaining the present invention, and
It is not construed as limiting the claims.
Method shown in Fig. 1 describes to judge that information is according to information source first from the angle of client
No is junk information, when information source cannot be defined as junk information, then is entered in itself by the information content
Row judges.
Specifically, in step step S120, judge whether information is rubbish letter according to information source
Breath includes：
The record in junk information source database by information source with local record is compared, and works as information
When source is junk information source, information is defined as junk information；Or,
Information source is sent to cloud server, and receives the configured information that cloud server is returned, when
When configured information determines information source for junk information source, information is defined as junk information.
The above method is on the basis of junk information identification validity is ensured, it is to avoid same without user
The content that information is believed is uploaded directly into caused by server infringement individual subscriber in the case of meaning is hidden
Private problem.
Furthermore, when information source cannot be defined as junk information, entered in itself by the information content
Row judges.Specifically, the content according to information judges whether information is that junk information includes：
According to the selection of user, the content of information is directly uploaded to cloud server, or, will believe
The alternative information of the content of breath is uploaded to cloud server；
The identification information that cloud server is returned is received, determines whether information is rubbish according to identification information
Information.
For example, when user starts the client for carrying out refuse messages identification for the first time in mobile terminal
When, ejection statement agreement asks the user whether to agree to directly by short message content in the statement agreement
Pass to cloud server；If user have selected agreement, when mobile terminal receives short message, directly
Connect and the content uploading of the short message is identified to cloud server.If user have selected disagreed,
Then when mobile terminal receives short message, perform previously described by the alternative information of the content of information
The step of reaching cloud server.The present embodiment is fundamentally solved existing from the wish of user
Have and individual subscriber privacy, the problem of harm user information safety are invaded present in technology.
Specifically, the alternative information of the content of information is uploaded into cloud server includes：
Calculate the corresponding cryptographic Hash of content of information；
The corresponding cryptographic Hash of the content of information is uploaded into cloud server.
Furthermore, the corresponding cryptographic Hash of content for calculating information includes：
Content to information carries out word segmentation processing；
Different vector values are assigned to each word after participle, collects the content correspondence of the information of being calculated
Simhash values.
For example, by taking short message as an example, with the corresponding cryptographic Hash of the content of short message as identification object, client
The process interacted with cloud server, realizes the identification to refuse messages.The method is ensureing
On the basis of refuse messages identification validity, it is to avoid in the case where agreeing to without user by short message
Content is uploaded directly into the problem of the infringement individual subscriber privacy caused by server；And by local
The place for interacting burden and cloud server of client and cloud server is alleviated after calculating treatment
Reason pressure, improves recognition efficiency, meets user's request.
In one embodiment of the invention, the method shown in Fig. 1 is further included：
When it is determined that the short message is refuse messages, intercept process is carried out to the short message.Blocking here
Cutting treatment can specifically include：Directly delete refuse messages；Or the short breath of rubbish is transferred to what is specified
In file, the treatment of user is waited；Or the prompting of refuse messages is carried out to user.
In one embodiment of the invention, the described corresponding cryptographic Hash of the content for calculating the short message
Refer to：It is the numerical value of regular length by the content map of the short message according to certain traditional hash algorithm,
The numerical value is referred to as cryptographic Hash, and the cryptographic Hash is the unique of the content of the short message and extremely compact numerical tabular
Show form.
Hash algorithm described in the present embodiment includes：HAVAL, MD2, MD4, MD5 or SHA1
Deng this quasi-tradition hash algorithm is all just like next essential characteristic：Seldom occurs hash in input domain
Conflict, the i.e. text for possible gap only one of which byte can also map out two entirely different Kazakhstan
Uncommon value.
For example, the content of two fraud text messages is respectively：It is " congratulations have suffered 50,000 yuan of Grand Prixs " and " respectful
Like you and suffered 10,000 yuan of Grand Prixs ", the content correspondence for calculating this two short messages by traditional hash algorithm is breathed out
Uncommon value is respectively 286 and 523.It can be seen that, two closely similar short messages of fraud tactics are calculated
The cryptographic Hash for going out is entirely different, and the identification pressure of cloud server in subsequent treatment may be caused excessive.
Therefore, for the deviation between the content correspondence cryptographic Hash of the short message for removing small range difference, subtract
The identification pressure of cloud server in light subsequent treatment.
In another embodiment of the present invention, calculate the short message content correspondence cryptographic Hash refer to：
Calculate the corresponding simhash values of content of the short message.Detailed process is as follows：
Content to short message carries out word segmentation processing.
Different vector values are assigned to each word after participle, collects the content correspondence for being calculated short message
Simhash values.
The solution of the present invention is described in detail by taking Tables 1 and 2 as an example below.
1 one processes of the corresponding simhash values of content of calculating short message of table
Table 1 shows corresponding according to the content of one specific embodiment calculating short message of the present invention
The process of simhash values.As shown in table 1, in the present embodiment, the short message that mobile terminal is received
It is：" our company opens common invoice generation, and generation does not open VAT invoice and professional invoice for our company.”
First, the corresponding vector form of initialization simhash values：A=Ao={ 0,0,0,0,0,0 }.
Then, the content to the short message carries out word segmentation processing：Our company/generation opens/and common/invoice/,
The generation of our company/or not opens/value-added tax/special/invoice/and/specialty/invoice；Obtain each after participle
Individual word is：Our company, Dai Kai, or not value-added tax is special, invoice, commonly, and, specialty.
According to certain traditional hash algorithm, corresponding 6 cryptographic Hash of each word are calculated respectively：
Our company：100110, Dai Kai：110000, no：101111, value-added tax：110001, it is special：
010110, invoice：101011, commonly：110100, and：110110, specialty：001001.
The word frequency of each word is calculated again as corresponding vector value, represents each word in short message content
Weight：Our company：2, Dai Kai：2, no：1, value-added tax：1, it is special：1, invoice：3, it is general
It is logical：1, and：1, specialty：1.
Constitute a vector B：In our company/100110/2, generation, opens/110000/2, not/101111/1,
Value-added tax/110001/1, special/010110/1, invoice/101011/3, common/110100/1, and
/ 110110/1, specialty/001001/1 }.
Each word in vectorial B is processed successively, processing mode is as follows：For each word, such as
It is really " 1 " that then the i-th dimension to vectorial A adds the word frequency of the word in the i-th bit of its cryptographic Hash；
If being in the i-th bit of its cryptographic Hash " 0 ", the i-th dimension to vectorial A subtracts the word frequency of the word.
For example, for our company/100110/2, vectorial A is changed into { 2, -2, -2,2,2, -2 }；Opened for generation
/ 110000/2, vectorial A are changed into { 2,2, -2, -2, -2, -2 }；By that analogy, each word is obtained corresponding
Vectorial A, as shown in table 1.
The corresponding vectorial A of each word is carried out collecting summation, vectorial Atotal=is obtained
{ 9, -1, -3,1,5,1 }, if the vectorial i-th dimension is negative, make simhash values correspondence to
The i-th dimension of amount is " 1 "；If the vectorial i-th dimension is negative, simhash values correspondence is made
The i-th dimension of vector is " 0 "；Final simhash values correspondence vector Afinal=is obtained accordingly
{1,0,0,1,1,1}。
Therefore, short message " our company opens common invoice in generation, our company not generation open VAT invoice and
Professional invoice." simhash values be 100111.
Table 2 another calculate short message the corresponding simhash values of content process
Table 2 shows corresponding according to the content of another specific embodiment calculating short message of the invention
The process of simhash values.As shown in table 2, in the present embodiment, the short message that mobile terminal is received
It is：" our company opens common invoice generation, and generation does not open special invoice and professional invoice for our company." its
The calculating process of simhash values similarly in table 1, will not be repeated here.It can be seen that, show in table 2
Vectorial Atotal={ 8, -2, -2,0,6,0 } is obtained after having gone out to collect summation, final simhash values are obtained
Correspondence vector Afinal={ 1,0,0,1,1,1 }.Therefore, " our company opens common invoice in generation to short message, originally
In generation, does not open special invoice and professional invoice for company." simhash values be 100111, with short message sheet
Company's Dai Kai common invoices, in generation, does not open VAT invoice and professional invoice for our company."
Simhash values are identical.
From the foregoing, in the calculating process of simhash values, on the basis of each word weight is kept,
Gradually ignore the specific size of the cryptographic Hash of each word, but with the positive and negative next of value after being collected summation
Distinguish each word, and often similar short message content to obtain symbol with its similar text structure identical
Summation vector Atotal, therefore, similar short message can have identical simhash values, overcome
The hash problem of traditional hash algorithm.
Additionally, in other embodiments of the invention, can by other means to each after participle
Word assigns vector value.
As embodiments of the invention, when certain information is defined as junk information, local or high in the clouds clothes
Junk information source database on business device records the information source of the information.It is, the rubbish in the present invention
Rubbish database of information sources will continuously record information source that is new, being classified as junk information.
Furthermore, the rubbish for being recorded on the junk information source database of local record and cloud server
Rubbish database of information sources interacts renewal.
Therefore, by taking terminal device mobile phone as an example, when frequent externally sending rubbish short message, the hand of the mobile phone
Machine number will be included into junk information source database quickly.By the propagation of internet, and client
The local junk information source database in end is obtained after real-time update, when mobile phone continuation transmission rubbish is short
During letter, the very first time is blocked by the client in junk information source by other identified its, is shielded.

Cryptographic Hash.
Step S220, will send the corresponding cryptographic Hash of the content of number or the short message and Hash of short message
Value storehouse is matched.
In this step, the junk information source database that cloud server is recognized according to historical record, sentences
Whether whether the number of the short message of disconnected upper hair has been recorded, i.e., be present in junk information source database
In.
Or, in this step, correspondence preserves the corresponding Hash of different short message contents in cryptographic Hash storehouse
Value and black or white identification information has been judged as it.Wherein, black identification information be indicate the information be
Junk information；White identification information is to indicate the information to be not junk information.
In one embodiment of the invention, the cryptographic Hash storehouse is that cloud server recognizes note according to history
Set by record, after cloud server carries out the identification of refuse messages every time, which kind of identification no matter chosen
