Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
As shown in fig. 1, according to an embodiment of the present application, there is provided a mail processing method applicable to a server, the method including:
step S101: and acquiring the original mail and extracting the mail content of the original mail.
At the terminal, the sender can send the mail, namely send the original mail. In this embodiment, the server first obtains the original mail to be sent, extracts the content of the mail, and then performs watermarking on the mail based on the content of the mail, so as to facilitate subsequent tracing. For example, in one example, the mail content may include a recipient mailbox address, a sender mailbox address, a mail header, attachment information, a mail body, and the like.
Step S102: and under the condition that N receiver mailbox addresses are included in the mail content, generating watermark information of each receiver mailbox address.
N is an integer greater than 1. The mail content comprises N receiver mailbox addresses, namely the mail content indicates that a plurality of receivers exist in the mail, and the original mail needs to be sent to the plurality of receivers. And generating watermark information under the condition that the mail content comprises N receiver mailbox addresses, wherein the watermark information of each receiver mailbox address is different.
Step S103: and adding watermarks to the original mail based on the watermark information of each receiver mailbox address to obtain the watermark mails of N receiver mailbox addresses.
Because the number of the receiver mailbox addresses is N, N watermark mails can be obtained, one receiver mailbox address corresponds to one watermark mail, and because the watermark information of each receiver mailbox address is different, the watermark information in the N watermark mails obtained is different, namely the N watermark mails are different. Therefore, the watermark mails received by different receivers can be distinguished conveniently, and even if the mail content is leaked, the leaked mail can be traced back to the divulger easily through the mail watermarks of the different receivers.
Step S104: and respectively sending the watermark mails of the N receiver mailbox addresses to the corresponding receiver mailbox addresses.
After the watermark mails of each receiver mailbox address are obtained, the watermark mails of the receiver mailbox address can be sent to the receiver mailbox address, and the watermark mails of each receiver mailbox address are respectively sent to the corresponding receiver mailbox address, so that the sending of N different watermark mails is realized.
In the mail processing method of the embodiment of the application, under the condition that the mail content comprises N receiver mailbox addresses, different watermark information can be generated for each receiver mailbox address, so that watermark mails obtained by adding watermarks according to the watermark information of each receiver mailbox address are different, even if a receiver leaks information in a mail after receiving the watermark mail, a divulger can be determined according to different watermark information, namely when the mail leaks information, the difficulty of tracing can be reduced, and the tracing of the divulger is facilitated.
In one embodiment, generating watermark information for each recipient mailbox address includes: acquiring i watermark types, wherein i is a positive integer; and generating watermark information corresponding to the watermark type of each receiver mailbox address under each watermark type.
In the process of generating the watermark information, i watermark types can be acquired first, and watermark processing of different watermark types can be performed on an original mail for multiple times, so that watermark information of a receiver mailbox address needs to be generated under each watermark type, i watermark types are provided, i watermark information are correspondingly generated on each receiver mailbox address, and i watermark information of the same receiver mailbox address are the watermark information belonging to the i watermark types, so that a guarantee is further provided for subsequent tracing. Whereby the watermark information for a recipient mailbox address includes i watermark types of watermark information. For example, if the i watermark types include an image bright watermark and a text dark watermark, the two types of watermark processing are required to be performed on the original mail, and the generated watermark information of each receiver mailbox address respectively includes the watermark information of the image bright watermark and the watermark information of the text dark watermark. The watermark mails of the mailbox addresses of the receiving parties generated subsequently comprise watermark information of the image bright watermarks and watermark information of the text dark watermarks, and further guarantee is provided for subsequent tracing.
In one embodiment, generating watermark information for each recipient mailbox address includes: performing condition matching on the mail content based on M preset conditions; generating watermark information of each receiver mailbox address under the condition that a first preset condition that mail content meets exists in M preset conditions
The method comprises the steps that M preset conditions exist, one preset condition which is met by mail content is matched in the M preset conditions through the mail content, and if the first preset condition which is met by the mail content exists in the M preset conditions, watermark information of each receiver mailbox address is generated.
The mail content meets the first preset condition to indicate that the original mail hits the watermarking condition, namely watermarking processing is required. That is, if the mail content satisfies the first preset condition, the watermark information of the mailbox address of each receiver can be generated, and if the mail content does not satisfy any preset condition, it indicates that the original mail does not hit the watermark condition, and the original mail is directly sent to the mailbox address of the receiver without performing watermark processing. That is, in this embodiment, condition matching is added, and only in the case that the first preset condition that the mail content satisfies exists in the M preset conditions, watermark information is generated, which is convenient for subsequent tracing, and moreover, it is not necessary to perform watermarking on each original mail, thereby reducing the amount of calculation. In one example, the mail content may be conditionally matched by regular matching, keyword matching, and the like.
In one example, the i watermark types are watermark types under a first preset condition, that is, i watermark types under the first preset condition are obtained.
In the case that the first preset condition that the mail content meets the first preset condition exists in the M preset conditions, the watermark information of the mailbox address of the receiver needs to be generated under each watermark type corresponding to the first preset condition, so that the watermark information of the mailbox address of one receiver includes the watermark information of the i watermark types. For example, if the i watermark types under the first preset condition include a picture bright watermark and a text dark watermark, the two types of watermark processing are required to be performed on the original mail, and the generated watermark information of the mailbox address of one receiving party includes the watermark information of the picture bright watermark and the watermark information of the text dark watermark. The watermark mails of the mailbox addresses of the receiving parties generated subsequently comprise watermark information of the image bright watermarks and watermark information of the text dark watermarks, and further guarantee is provided for subsequent tracing.
In one example, the generating of the i watermark information of the i watermark types for each recipient mailbox address may be that, in a case that there is a first preset condition that mail content satisfies among the M preset conditions, the generating of the i watermark information of the i watermark types for each recipient mailbox address. Not only is the follow-up tracing convenient, but also each original mail does not need to be watermarked, and the calculation amount is reduced.
In one embodiment, the first preset condition is one of M preset conditions, and the M preset conditions include preset conditions of at least one of a receiver mailbox address, a sender mailbox address, a mail header, attachment information, and a mail body.
The method includes that M preset conditions can be preset, and a receiver mailbox address, a sender mailbox address, a mail header, attachment information and a mail body can be combined randomly to form one preset condition, namely at least one of the receiver mailbox address, the sender mailbox address, the mail header, the attachment information and the mail body can form one preset condition, for example, the receiver mailbox address, the sender mailbox address, the mail header, the attachment information and the mail body can form one preset condition respectively, the receiver mailbox address and the sender mailbox address are combined to correspond to one preset condition related to the receiver mailbox address and the sender mailbox address, and the receiver mailbox address, the sender mailbox address and the mail body are combined to correspond to one preset condition related to the receiver mailbox address, the sender mailbox address and the mail header. The first preset condition is a preset condition that the mail content in the M preset conditions is satisfied, that is, the first preset condition is one of preset conditions of at least one of a receiver mailbox address, a sender mailbox address, a mail header, attachment information and a mail text, so that the preset condition that the mail content is satisfied can be found from the M preset conditions to determine that the original mail needs to be watermarked, that is, the original mail meeting the first preset condition is watermarked, not only is subsequent tracing facilitated, but also each original mail does not need to be watermarked, and the calculation amount is reduced.
In one embodiment, obtaining the original mail includes: intercepting an original mail through a switching plug-in;
sending the watermark mail of the receiver mailbox address to the receiver mailbox address, which comprises the following steps: and sending the watermark mail of the receiver mailbox address to the receiver mailbox address through a protocol synchronous mail interface of the switching plug-in.
The Exchange plug-in is installed in the server, namely the Exchange plug-in, the server can also be called as an Exchange server, the original mail sent by a sender can be intercepted and obtained through the Exchange plug-in, namely when the original mail is sent through the Exchange server, the Exchange server can call a mail interception callback function in the plug-in, in the callback function, the mail content of the original mail can be extracted, the Exchange plug-in intercepts the normal sending flow of the original mail, namely the original mail can be quickly and accurately obtained through the Exchange plug-in, and the acquisition of the original mail is facilitated.
After obtaining the watermark mail, the Exchange server calls a protocol synchronous mail interface to send the watermark mail, wherein the protocol synchronous mail interface is an Exchange Web Service (EWS) interface, and the mail is sent through the interface, so that the mail sending speed can be improved.
The above mail processing procedure will be described in detail with reference to an embodiment.
First, an Exchange plug-in is installed. And installing an Exchange plug-in module of the mail watermark according to an Exchange server standard API (application programming Interface) Interface.
Then, the original mail is intercepted and acquired through the Exchange plug-in. When an original mail is sent through the Exchange server, the Exchange server calls a mail interception callback function in the plug-in module, and in the callback function, mail content of the original mail is extracted, wherein the mail content can comprise a sender mailbox address, a receiver mailbox address, a copying mailbox address list, a secret mail address list, a mail title, an attachment list, a picture list and the like, namely the receiver mail address can comprise at least one Exchange plug-in among the receiver mailbox address, the copying mailbox address list and the secret mail address list to intercept a normal sending process of the original mail.
Second, the mail content rules match. According to the extracted mail content, rule matching, namely condition matching, is executed, each rule comprises a condition part and a policy part, the condition part defines the hit condition of the rule, namely the preset condition, and can be the hit condition of any combination of any fields of the mail content, and the policy part defines the mail watermarking options after the hit condition (for example, background bright watermarks, text dark watermarks, picture bright watermarks, picture dark watermarks, document watermarks, audio watermarks, text-to-picture watermarks and other watermarking options). The rules are managed by an independent rule server, and an administrator or a mail sender can determine whether to configure the watermark rules and the watermark options according to the confidentiality degree of the mail. When the preset conditions in all the rules are not hit, the Exchange plug-in releases the intercepted mail, namely, the original mail is directly sent without watermarking.
Further, the recipient list is disassembled. When the mailbox address, the copy mailbox address and the secret delivery mailbox address list of the receiver contain a plurality of mailbox addresses or the mailbox addresses are mailbox group addresses, in order to embed different watermark information (convenient for secret leakage tracing) into the mail content received by each receiver, all the mailbox addresses of the receiver need to be extracted, and the mailbox group addresses need to be split at the same time to acquire all the mailbox addresses in the mailbox group, wherein the mailbox is split based on LDAP (lightweight directory access protocol) and Exchange plug-in. And merging and de-duplicating the disassembled receiver mailbox address list so as to obtain N receiver mailbox addresses.
And generating the bright and dark watermark parameter information. And acquiring mail watermark options, namely watermark types, from the rules of the original mail hit, wherein the watermark options in the hit rules comprise background bright watermarks, text dark watermarks, picture bright watermarks, picture dark watermarks, document watermarks and audio watermarks, and generating background bright watermark parameters, text dark watermark parameters, picture bright watermark parameters, picture dark watermark parameters, document watermark parameters and audio watermark parameters with unique identifiers for each disassembled receiver mailbox address, namely generating watermark information of each watermark type for subsequent watermark adding.
And adding the watermark and generating a watermark mail. And according to the watermark type and the watermark information, performing mail watermarking for each receiver mailbox address to generate a watermark mail.
And calling an Exchange Web Service (EWS) interface to send the watermark mail at high speed. And finally generating a watermark mail for each receiver, importing the watermark mail into an inbox of the receiver through an EWS interface provided by an Exchange server, enabling the receiver to check the watermark mail, wherein the watermark mail comprises watermark information capable of uniquely identifying the identity of the receiver, and when a certain receiver leaks the watermark mail (the leakage type comprises screen capture, character copy, mail attachment outward transmission and the like). The system administrator or the confidential mail sender can provide the leaked and transmitted information, inquire in the mail watermarking system and extract the watermarking information of the divulger so as to confirm the identity of the divulger.
In the process of adding a watermark and generating a watermark mail, a watermark adding process is performed by using the watermark option and the watermark information of the watermark option in the hit rule as shown in fig. 2. Namely, the watermark option is firstly obtained, and the watermark information of the receiver under the watermark option is obtained. Judging whether the obtained watermark option comprises a character-to-picture option, if so, processing the character-to-picture in the original mail, if not, judging whether the obtained watermark option comprises a background bright watermark option (the judgment is also carried out after the character-to-picture processing), if so, adding a background bright watermark to the mail, if not, judging whether the obtained watermark option comprises a text dark watermark option (the judgment is also carried out after the background bright watermark is added), if so, adding a text dark watermark to the mail, if not, judging whether the obtained watermark option comprises a picture bright watermark option (the judgment is also carried out after the text dark watermark is added), if so, adding a picture bright watermark to the mail, if not, judging whether the obtained watermark option comprises a picture dark watermark option (the judgment is also carried out after the picture bright watermark is added) or not, if so, adding a picture dark watermark to the mail, if not, judging whether the obtained watermark options comprise a document watermark option (the judgment is also carried out after the picture dark watermark is added), if so, adding the document watermark to the mail, if not, judging whether the obtained watermark options comprise an audio watermark option (the judgment is also carried out after the document watermark is added), if so, adding the audio watermark to the mail, and if not, indicating that the watermark options are judged to be finished, wherein the latest obtained watermark mail can be the final watermark mail. And then transmits it.
