[Detailed description of the invention]
Described herein the drawings are intended to provide a further understanding of the invention, constitutes part of this application, but
It does not constitute improper limitations of the present invention, in the accompanying drawings:
Fig. 1 is the flow chart of short message information extracting and analysis method of the present invention.
Fig. 2 is the embodiment of a statistical graph of short message analysis of the present invention.
[specific embodiment]
Come that the present invention will be described in detail below in conjunction with attached drawing and specific embodiment, illustrative examples therein and says
It is bright to be only used to explain the present invention but not as a limitation of the invention.
The embodiment of the present invention operates on Android phone platform, and main thought is: according to the regular expressions of agreement
Formula, the intelligent extraction key message from short message text, optimize information exhibition method, carry out ASSOCIATE STATISTICS operation, whole process without
User is needed to participate in manually.
Referring to attached drawing 1, it illustrates the basic procedure of short message information extracting of the invention and analysis method, which includes
Following steps:
Step 100: obtaining a short message record to be analyzed.
Short message information extracting and analysis method of the invention can be directed to old short message, can also be directed to new message, therefore walk
Actually there are two data sources for the short message to be analyzed obtained in rapid 100: one is read from the note data library of mobile phone
One short message record；The other is intercepting each new message that mobile phone receives using short message mechanism is intercepted.Based on Android
On the one hand the open platform of mobile phone, the cell phone system realized using method of the invention can read the note data of mobile phone
Library, on the other hand can be in one SMS interception program of running background, to intercept the new message received.Based on the two data come
Source, the old short message of the available each of step 100 and new message, to complete subsequent step.
Step 200: according to the number record in database, the short message being recorded and carries out numbers match, determines the short message
The sender of record；If failing to be matched to number, which is not analyzed, return step 100.
Every short message record has a number of a transmission short message, this number be it is corresponding with short message sender, it is attached
Several examples are given in Fig. 1, the number including Construction Bank is 95533, and the number of industrial and commercial bank is 95588 etc..It is same
Sender may also have different numbers, these numbers and sender's associated storage are in the number record of database.Therefore,
By sender's number of analysis short message record, the sender of short message can be confirmed, this is first letter extracted from short message
Breath.But the present invention only analyzes the short message of specific sender, such as each bank, express delivery, train ticket ticketing website etc.
Deng for common daily short message without processing, therefore the number record in database has only included and has needed to carry out short message analysis
Number, if the number of short message sender does not just analyze it not in the number record of database, to return to step
Rapid 100 to handle next short message.
Step 300: the sender recorded according to the short message obtains the canonical table of the short message of the sender from data base querying
Up to formula.
Short message transmitted by each sender may have different types, and by taking bank as an example, the short message sent may
It is consumption short message, it is also possible to which account amount of money changes short message.But for the short message of each type, messaging format is usual
It is fixed, therefore can is the short message of each type, determines a regular expression corresponding with its format, these canonicals
Expression in advance with sender's associated storage in the database, thus step 300 can obtain the sender couple according to sender
All regular expressions answered.
Step 400: the regular expression obtained based on step 300 one by one matches short message to be analyzed, if do not had
There is a regular expression that can match the short message, then abandons the analysis to short message, return step 100；If finding a canonical
Expression formula can match the short message, then according to the regular expression, extract the key message in short message.
Three examples of key message are shown in attached drawing 1: first example is extracted from bank's consumption short message
Transaction card number, exchange hour, transaction amount and transaction details；Second example is from bank account balances inquiry return receipt short message
Transaction card number, exchange hour, transaction amount and the account balance of extraction；Third example is the order extracted from express delivery short message
Number, distribution time and picking number.These key messages are all to be matched by regular expression to messaging format, are extracted
's.
Step 500: by the short message extracted key message and its sender's associated storage in the database.
After key message is extracted, storage in the database, in this way it is subsequent can based on these information into
The further statistical analysis of row.
Step 600: it is for statistical analysis to the key message stored in database, and show statistic analysis result.
Since the key message extracted is all unified structured content, statistical analysis is carried out with regard to very easy,
Attached drawing 2 shows the example of a statistical graph, is statisticallyd analyze to bank's consumption details of every month, and by soft
Part showing interface statistical graph.The present invention does not make limitation, art technology to specific statistical analysis and diagrammatic representation method
Personnel are appreciated that the key message based on above-mentioned acquisition, can carry out various statistics and analysis processes as known in the art.
In said short message information extraction process, regular expression is the core tool for extracting short message, it reflects short message
Correct format.But messaging format may be with time change.On the one hand, short transmitted by each sender's number
Letter format is possible changed, on the other hand, it is possible that new sender's number (number including new sender,
Or the new digit of old sender), new number would generally bring new messaging format.Therefore, regular expression and its association
Sender, number needs update.
A kind of common update method is that network updates in the prior art, it can in surfing Internet with cell phone, on network
Server is updated to inquire and download new regular expression.But, on the one hand, network update needs to expend network flow, another
Aspect, sometimes mobile phone may and not have the environment that can be surfed the Internet.Therefore, the invention proposes a kind of new regular expressions
Formula and the update method of related sender, number, this method can be updated by short message, if mobile phone can receive it is short
Letter, so that it may carry out relevant updates.
Specific step is as follows for update:
(1) a update server is set, and each needs the mobile phone updated all to be stepped in advance in the update server
Note, register information includes phone number, and each needs all to store the digital certificate of the update server on the mobile phone updated.
(2) when needing more new information, update server will more new information and current date according to predefined format into
Row is packaged, and obtains more new packets.
Here more new information may be there are many situation, comprising: increases new regular expressions for some existing sender
Formula；Increase new number for some existing sender；Increase new sender and its number, regular expression.Either where
Kind more new information, can pre-define packing format, which is packaged according to the packing format.In order to can
To use short message to be updated, each more new packets are only packaged a more new information.More new information is also added in the current date
Packet is the timeliness and safety in order to guarantee more new packets, and a more new information is avoided to be repeated to send by people's malice.
(3) for the phone number P registered on updating server, the value that server calculates its mould 256 is updated, i.e.,
Calculate PM=P mod 256；Therefore the PMDigit be no more than 8, that is, be limited within a byte.By more new packets
Each byte and the PMExclusive or is carried out, to obtain the second more new packets after an exclusive or.
3 exclusive or process through the above steps gets up the image watermarking of more new packets, and for different hands
Machine number, the second more new packets obtained after exclusive or are different from, then further improve safety.In addition, institute in step 3
The P usedMIt is fixed and invariable for each phone number, therefore in practical applications can be with each P computed in advanceM。
(4) server is updated to be digitally signed the second more new packets using the private key of the digital certificate of oneself.
Why digital signature is used, is the safety in order to guarantee more new information, to prevent someone from pretending to be more new demand servicing
Device damages mobile phone safe, since to each phone number, the second more new packets are different from, then its digital signature also not phase
Together.
(5) update server to the described second more new packets carry out Base64 coding, using obtained coding result as
First short message is sent to phone number P.
(6) it updates server and Base64 coding is also carried out to the digital signature that step 4 obtains, using coding result as second
Short message is sent to phone number P.
(7) it updates server and step 3-6 is repeated to the phone number of each registration, so that the phone number of each registration
It can receive first short message and the second short message.
(8) after a mobile phone receives above-mentioned first short message and the second short message, if it find that the sender of this two short messages
Number is the number for updating server, then carries out Base64 decoding to two short messages, obtains the second more new packets sum number word label
Name.
(9) mobile phone is using the digital certificate for updating server, the second more new packets sum number word obtained to step 8
Signature carries out signature verification.If verifying does not pass through, ignores then two short messages, otherwise continue subsequent step；
Based on attack means such as present pseudo-base stations, it is insecure for updating server by number judgement merely, therefore this
Invention guarantees the reliability updated by digital signature authentication.
(10) mobile phone calculates P based on the phone number P of itselfM=P mod 256；Then step 8 is obtained second
The each byte and the P of more new packetsMExclusive or is carried out, to obtain original more new packets.The step for be actually
The inverse process of step 3.
(11) mobile phone parses the content of the more new packets using predefined format, obtains more new information and update
Date information in packet；Whether the difference for verifying the date information and current date is greater than predetermined threshold, if it does, explanation
The more new packets have been subjected to the phase, then ignore the more new packets；If it is not greater, then the update information update number based on acquisition
According to library.
On the one hand above-mentioned update method ensure that the safety of more new information, prevent from pretending to be update server, on the other hand
Without surfing Internet with cell phone, can be updated in the case where mobile phone is offline；So that short message of the invention is extracted with analysis method more
Add safe and reliable, timely.
The above description is only a preferred embodiment of the present invention, thus it is all according to the configuration described in the scope of the patent application of the present invention,
The equivalent change or modification that feature and principle are done, is included in the scope of the patent application of the present invention.
