In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a method for identifying authentication information according to an embodiment of the present invention includes:
step 100, after receiving a message, extracting clauses containing key information and target information from the message;
step 101, determining the distance between key information and target information in each clause;
and 102, taking the target information in the clause with the minimum distance as verification information.
The embodiment of the invention can set the format of the target information, and the information conforming to the format is used as the target information. For example, information in which N or more consecutive digits are all numbers, all letters, and a combination of numbers and letters can be used as the target information.
Taking N as an example of 4, if the message has 1234, determining that the message is the target information; if the message has ABCD, determining the message as target information; if 12B3CD exists in the message, the target information is determined.
The format of the above object information is only an example, and any format is a scheme using an embodiment of the present invention.
The key information of the embodiment of the present invention may be any information capable of indicating that the message has the verification information, such as: an activation code, a dynamic code, a check code, an authentication code, a confirmation code, a check code, an authentication code, an activation code, a check code, a dynamic code, a check code, a confirmation code, a short message password, a dynamic password, a transaction code, an internet access password, a dynamic login password, and the like.
The message of the embodiment of the invention can be any received message, such as a message received through instant messaging software, a short message received through a short message and the like.
Optionally, after receiving the message, it may be determined whether the received message is a notification message, and if the received message is a notification message, it is further determined whether the received message includes preset key information; if not, the solution of the embodiment of the present invention may not be executed.
And judging whether the messages in different forms are notification messages or not in different modes. Taking the short message as an example, the judgment can be made by the number of the short message.
The number head of the general person is 131, 138, 139, etc., and if the number head is not the number of the set person at the time of judgment, it can be determined that the number to which the message is sent is the notification number, and the message is the notification type message.
Optionally, after determining that the received message includes the key information and/or the target information, extracting a clause including the key information and the target information from the message.
Judging whether the message comprises key information and/or target information, wherein the judgment can be carried out after the message is determined to be a notification message; judgment can also be carried out simultaneously; or judging whether the message comprises the key information and/or the target information, and judging whether the message is the notification message after the key information and/or the target information are determined to exist.
Optionally, when a clause including key information and target information is extracted from the message, there are two ways:
extracting clauses containing key information from the message in a first extraction mode; and extracting clauses containing target information from the clauses containing the key information.
And if all clauses do not contain the clause of the target information, displaying the received message to the user, and determining the verification information by the user.
And if the clauses containing the target information exist in all the clauses, determining the distance between the target information in the clause and the key information in the clause aiming at the selected clause.
For example, the content of the received message is "your account is undergoing 206.00 dollar transactions, check code: 650717, neither kill nor tell others the check code, which asks for the line 12345. "
The clause extracted from the message is "check code: 650717, neither the "kill" nor the "check code" to others, and "check code question hotline 12345". The clause containing the target information is' check code: 650717 "and" check code query hotline 12345 ".
Optionally, when a clause containing key information is extracted from a message, determining all key information included in the received message;
and aiming at one piece of key information, determining a preset mark positioned before the key information and a nearest preset mark positioned after the key information from the message, and taking the content between the two preset marks as a clause.
The preset identifier may be set according to experience, and the preset identifier may include part or all of the following information:
punctuation, white space (applicable to the case where there is no punctuation in front of the key information, such as the key information being at the top of the received message).
The punctuation herein may include one or more. And the specific method can be determined according to language habits and the format of the message containing the verification information. In specific implementation, a large number of messages can be collected for perfection, and the preset identification can be updated through a network.
Such as punctuation including commas and periods.
The received message is "[ AA ] welcome to use AA, 907050 (dynamic authentication code). Please fill in within 30 minutes to contact the phone 1008222. "
In this message, whether the short message is an authentication code short message or not can be judged through the "authentication code", if the short message contains the key information of the "authentication code", a comma or a period before the "authentication code" (generally, the first comma or period before) and a comma or a period after the "authentication code" (generally, the first comma or period after) are found, and the content between two preset marks is taken as a clause, namely 907050 (dynamic authentication code) is taken as a clause.
In practice, if the key information is located in parentheses (e.g., middle parentheses, small parentheses, large parentheses, etc.), one comma or period before the left parentheses (typically the first comma or period before) and one comma or period after the right parentheses (typically the first comma or period before) may be found, and the content between the two predetermined identifiers is taken as a clause.
Also for example, the content of the received message is "your account is undergoing 206.00 dollar transactions, check code: 650717, nothing to kill tells others the check code. "
Two clauses are obtained according to the scheme of extracting the clauses: "check code: 650717 "and" neither kill tells others a check code "
When a clause containing target information is selected from all clauses, as the ' death can not tell others about the check code ' does not contain the target information, the last sentence containing the target information is a ' check code: 650717".
Extracting a clause containing target information from the message in a second extraction mode; and extracting clauses containing key information from the clauses containing the target information.
And if all clauses do not contain clauses containing key information, displaying the received message to the user, and determining the verification information by the user.
And if the clauses containing the key information exist in all the clauses, determining the distance between the target information in the clause and the key information in the clause aiming at the selected clause.
Optionally, when a clause including target information is extracted from the message, determining all target information included in the received message;
and determining a preset identifier positioned in front of the target information and a nearest preset identifier positioned behind the target information from the message, and taking the content between the two preset identifiers as a clause.
The preset identifier may be set according to experience, and the preset identifier may include part or all of the following information:
punctuation, white space (applicable to the case where there is no punctuation in front of the key information, such as the key information being at the top of the received message).
The punctuation herein may include one or more. And the specific method can be determined according to language habits and the format of the message containing the verification information. In specific implementation, a large number of messages can be collected for perfection, and the preset identification can be updated through a network.
The specific extraction process is similar to the extraction method, and is not described herein again.
In practice, if the target information is located in parentheses (e.g., middle parentheses, small parentheses, large parentheses, etc.), one comma or period before the left parentheses (typically the first comma or period before) and one comma or period after the right parentheses (typically the first comma or period before) may be found, and the content between the two predetermined identifiers is taken as a clause.
The specific extraction process is similar to the extraction method, and is not described herein again.
When the distance between the target information in the clause and the key information in the clause is determined for a selected clause, because the positions of the target information and the key information are different, the target information may be located in front of the key information or behind the key information, so that two distance determining modes are provided in the embodiment of the invention for different situations.
Determining a first mode, aiming at a selected clause, if the target information in the clause is positioned in front of the key information, determining the distance between the target information in the clause and the key information in the clause according to the following formula:
distance＝p_keyword-(p_number+length_number)；
wherein, distance is the distance between the target information in the clause and the key information in the clause;
p _ number is the distance between the first symbol of the target information in the clause and the first symbol of the message;
length _ number is the length of the target information;
the p _ key is the distance between the first symbol of the key information in the message and the first symbol of the message.
Assume that the received message is "[ AA ]907050 (dynamic authentication code). Please fill in 30 minutes. One of the clauses is "[ AA ]907050 (dynamic verification code)", and the distance of the branch is:
defining the position of the first symbol "[" in the message as 0, and sequentially adding 1 to the subsequent positions, so that the position p _ number of the first symbol "9" of the target information "907050" is 4; the length _ number of the target information "907050" is 6, and the position p _ keyword of the first symbol "mobile" of the key information "dynamic verification code" is 11; the distance is 11- (4+6) ═ 1.
And determining a second mode, aiming at the selected clause, if the target information in the clause is positioned behind the key information, determining the distance between the target information in the clause and the key information in the clause according to the following formula:
distance＝p_number-(p_keyword+length_keyword)；
wherein, distance is the distance between the target information in the clause and the key information in the clause;
p _ number is the distance between the first symbol of the target information in the clause and the first symbol of the message;
the p _ keyword is the distance between the first symbol of the key information in the message and the first symbol of the message;
the length _ key is the length of the key information.
Assume that the received message is "[ AA ] (dynamic authentication code) 907050. Please fill in 30 minutes. One of the clauses is "[ AA ]907050 (dynamic verification code)", and the distance of the branch is:
defining the position of the first symbol "[" in the message as 0, and sequentially adding 1 to the subsequent positions, so that the position p _ number of the first symbol "9" of the target information "907050" is 11; the length _ keyword of the key information 'dynamic verification code' is 5; the position p _ keyword of the first symbol "dynamic" of the key information "dynamic verification code" is 5; the distance is 11- (5+5) ═ 1.
The embodiment of the invention can take one letter, one number, one punctuation and one Chinese character as one symbol.
Optionally, when the verification information is determined from all the target information in the selected clause according to all the determined distances, the target information with the shortest distance to the key information is used as the verification information.
For example, the content of the received message is "your account is undergoing 206.00 dollar transactions, check code: 650717, neither kill nor tell others the check code, which asks for the line 12345. "
The clause extracted from the message is "check code: 650717, neither the "kill" nor the "check code" to others, and "check code question hotline 12345".
And selecting a clause containing target information from all clauses as a check code: 650717 "and" check code query hotline 12345 ".
The check code is determined as above: 650717 "distance 23- (19+3) ═ 1;
the "check code query hotline 12345" distance is determined to be 50- (43+3) ═ 4 in the above manner.
Due to the check code: 650717 "distance (i.e., 1) is less than" check code query hot line 12345 "distance (i.e., 4), then" check code: 650717 "as verification information.
In implementation, after the verification information is determined, the page for verifying the verification information is determined, and the verification information is automatically filled in the position where the verification information is filled in the determined page. The page can be a webpage page, an application page, or a page opened in other forms.
As shown in fig. 2, the method for extracting clauses according to the embodiment of the present invention includes:
and step 200, receiving a message.
Step 201, judging whether the received message includes preset key information; if so, go to step 202, otherwise, go out of the flow.
Step 202, determining a piece of key information not extracted from the message.
Step 203, judging whether the determined key information is in brackets, if so, executing step 204; otherwise, step 205 is performed.
Step 204, find the first comma or period before the left brace and the first comma or period after the right brace, and perform step 206.
Step 205, find the first comma or period before the key information, and find the first comma or period after the key information, and perform step 206.
Step 206, the content between the first comma or period before the key information and the first comma or period after the key information is taken as a clause.
Step 207, judging whether key information which is not extracted exists, if so, returning to the step 202; otherwise, continuing to execute the subsequent step of selecting the clause containing the target information from all the clauses.
The following will illustrate the scheme of the present invention by taking the first extraction method as an example.
As shown in fig. 3, the complete method for identifying authentication information according to the embodiment of the present invention includes:
step 300, receiving a message.
Step 301, after determining that the received message includes preset key information, extracting at least one clause from the message. (see FIG. 2 for details of step 301)
Step 302, judging whether clauses containing target information exist in all clauses, and if yes, executing step 303; otherwise, the received message is displayed to the user.
Step 303, selecting a clause containing the target information from all clauses.
Step 304, judging whether the number of clauses containing target information is not less than 2; if so, go to step 305; otherwise, step 309 is performed.
Step 305, selecting a clause with undetermined distance from all clauses.
And step 306, determining the distance between each target information in the clause and the key information in the clause.
Step 307, judging whether all clauses determine the distance, if so, executing step 309; otherwise, the procedure returns to step 305.
And 308, taking the target information with the shortest distance to the key information as verification information.
And step 309, taking the target information in the clause as verification information.
Based on the same inventive concept, the embodiment of the present invention further provides a device for identifying verification information, and because the principle of solving the problem of the device is similar to the method for identifying verification information in the embodiment of the present invention, the implementation of the device may refer to the implementation of the method, and repeated details are not repeated.

The specific extraction process is similar to the extraction method, and is not described herein again.
In practice, if the target information is located in parentheses (e.g., middle parentheses, small parentheses, large parentheses, etc.), one comma or period before the left parentheses (typically the first comma or period before) and one comma or period after the right parentheses (typically the first comma or period before) may be found, and the content between the two predetermined identifiers is taken as a clause.
The specific extraction process is similar to the extraction method, and is not described herein again.
When the distance between the target information in the clause and the key information in the clause is determined for a selected clause, because the positions of the target information and the key information are different, the target information may be located in front of the key information or behind the key information, so that two distance determining modes are provided in the embodiment of the invention for different situations.
In the first determination mode, for a selected clause, if the target information in the clause is located in front of the key information, the distance determination module 401 determines the distance between the target information in the clause and the key information in the clause according to the following formula:
distance＝p_keyword-(p_number+length_number)；
wherein, distance is the distance between the target information in the clause and the key information in the clause;
p _ number is the distance between the first symbol of the target information in the clause and the first symbol of the message;
length _ number is the length of the target information;
the p _ key is the distance between the first symbol of the key information in the message and the first symbol of the message.
Assume that the received message is "[ AA ]907050 (dynamic authentication code). Please fill in 30 minutes. One of the clauses is "[ AA ]907050 (dynamic verification code)", and the distance of the branch is:
defining the position of the first symbol "[" in the message as 0, and sequentially adding 1 to the subsequent positions, so that the position p _ number of the first symbol "9" of the target information "907050" is 4; the length _ number of the key information "907050" is 6, and the position p _ keyword of the first symbol "dynamic" of the target information "dynamic authentication code" is 11; the distance is 11- (4+6) ═ 1.
In the second determination method, for a selected clause, if the target information in the clause is located behind the key information, the distance determination module 401 determines the distance between the target information in the clause and the key information in the clause according to the following formula:
distance＝p_number-(p_keyword+length_keyword)；
wherein, distance is the distance between the target information in the clause and the key information in the clause;
p _ number is the distance between the first symbol of the target information in the clause and the first symbol of the message;
the p _ keyword is the distance between the first symbol of the key information in the message and the first symbol of the message;
the length _ key is the length of the key information.
Assume that the received message is "[ AA ] (dynamic authentication code) 907050. Please fill in 30 minutes. One of the clauses is "[ AA ]907050 (dynamic verification code)", and the distance of the branch is:
defining the position of the first symbol "[" in the message as 0, and sequentially adding 1 to the subsequent positions, so that the position p _ number of the first symbol "9" of the target information "907050" is 11; the length _ keyword of the key information 'dynamic verification code' is 5; the position p _ keyword of the first symbol "dynamic" of the key information "dynamic verification code" is 5; the distance is 11- (5+5) ═ 1.
The embodiment of the invention can take one letter, one number, one punctuation and one Chinese character as one symbol.
Optionally, when determining the verification information from all the target information in the selected clause according to all the determined distances, the information determining module 402 uses the target information with the shortest distance to the key information as the verification information.
For example, the content of the received message is "your account is undergoing 206.00 dollar transactions, check code: 650717, neither kill nor tell others the check code, which asks for the line 12345. "
The clause extracted from the message is "check code: 650717, neither the "kill" nor the "check code" to others, and "check code question hotline 12345".
And selecting a clause containing target information from all clauses as a check code: 650717 "and" check code query hotline 12345 ".
The check code is determined as above: 650717 "distance 23- (19+3) ═ 1;
the "check code query hotline 12345" distance is determined to be 50- (43+3) ═ 4 in the above manner.
Due to the check code: 650717 "distance (i.e., 1) is less than" check code query hot line 12345 "distance (i.e., 4), then" check code: 650717 "as verification information.
In implementation, after the verification information is determined, the page for verifying the verification information is determined, and the verification information is automatically filled in the position where the verification information is filled in the determined page. The page can be a webpage page, an application page, or a page opened in other forms.
From the above, it can be seen that: the method comprises the steps of extracting clauses containing key information and target information from a message, determining the distance between the key information and the target information in each clause, taking the target information in the clause with the minimum distance as verification information, extracting the clause containing each continuous number, letter or combination thereof from the whole information when the received information contains a plurality of continuous numbers, letters or combination thereof according to the distance between the target information in the clause and the key information in the clause, then taking the continuous numbers, letters or combination thereof contained in the clause with the minimum distance as the verification information, and determining the verification information from all the target information, so that the method can be applied to formats of more information and improve the identification accuracy.
