数字水印模块嵌入在短信保护单元中， 主要包括： 数字水印信息、 水 印嵌入算法， 以及禁止短信转发函数。 数字水印信息可以是图像、 数字、 文本等， 也可以来自手机摄像机拍摄的图像或视频。 如果选择的数字水印 信息来源于摄像机， 此时调用摄像机模块， 即所述摄像机模块主要用来拍 摄照片、 视频等； 当选择的数字水印信息为来自摄像机模块拍摄的照片或 视频时， 摄像机模块会被数字水印模块调用。 水印嵌入算法有鲁棒性、 脆 弱性等多种经典的数字水印算法， 这些算法嵌入在数字水印模块中。 The digital watermarking module is embedded in the short message protection unit, and mainly includes: digital watermark information, watermark embedding algorithm, and prohibition of short message forwarding function. The digital watermark information can be images, numbers, text, etc., or it can be from images or videos taken by a mobile phone camera. If the selected digital watermark information is from the camera, the camera module is called, that is, the camera module is mainly used for taking photos, videos, etc.; when the selected digital watermark information is a photo or video taken from the camera module, the camera module will Called by the digital watermarking module. The watermark embedding algorithm has many classic digital watermarking algorithms such as robustness and fragility. These algorithms are embedded in the digital watermarking module.
其中， 若发送的短信是纯文本短信， 则数字水印信息嵌入在短信的某 一行文字中， 假如用户输入的文字短信共 n行， 那么将数字水印信息可以 嵌入在第 [n/2]行的文字中， 其中， []为取整符号， 若短信的每一行可以输入 m个字， 则嵌入在纯文本短信中的水印的中心位置在短信的第 [n/2]行的第 [m/2]个字的位置处。 若发送的短信中载有图片、 铃声、 动画， 甚至移动游 戏、 MP3、 视频节目等， 则数字水印信息主要嵌入在这些多媒体信息中。 Wherein, if the sent short message is a plain text short message, the digital watermark information is embedded in a certain line of text of the short message, and if the text text input by the user has a total of n lines, the digital watermark information can be embedded in the [n/2] line. In the text, where [] is the rounding symbol, if each line of the short message can input m words, the center position of the watermark embedded in the plain text message is in the [n/2] line of the message [m/ 2] The position of the word. If the sent short message contains pictures, ringtones, animations, or even mobile games, MP3s, video programs, etc., the digital watermark information is mainly embedded in the multimedia information.
短信发送方在新编辑的短信中成功嵌入数字水印信息后， 会调用加密 模块， 加密模块主要对嵌入的数字水印信息设置一个加密密码， 从而达到 对需要保护的短信进行双重保护作用。 因此， 即使短信接收终端将这些信 息通过 USB拷贝到 PC机， 并上传到网络中， 因这些信息中嵌入了数字水 印信息， 从而可以有效保护短信发送者对信息的所有权。 短信发送者将含 有数字水印信息的短信发出后， 短信接收方将接收到的短信转发时会调用
数字水印模块中的禁止短信转发函数， 禁止转发该短信。 After the SMS sender successfully embeds the digital watermark information in the newly edited short message, the encryption module is called. The encryption module mainly sets an encryption password for the embedded digital watermark information, thereby achieving double protection for the short message to be protected. Therefore, even if the short message receiving terminal copies the information to the PC via USB and uploads it to the network, since the digital watermark information is embedded in the information, the short message sender's ownership of the information can be effectively protected. After the short message sender sends the short message containing the digital watermark information, the short message receiver will call the received short message when it is forwarded. The SMS forwarding function is prohibited in the digital watermarking module, and the short message is prohibited from being forwarded.
进一步地， 所述短信转发单元包括： Further, the short message forwarding unit includes:
短信编辑模块， 用于对收到的短信进行编辑； a short message editing module for editing the received short message;
短信发送模块， 主要用于实现发送短信的功能。 作为短信发送方， 若 短信中已经嵌入了数字水印信息， 那么在短信发送时会载着嵌有数字水印 的短信进行发送， 若短信中没有嵌入数字水印信息， 发送时按普通短信处 理； 作为短信接收方， 对收到的短信进行编辑后再进行发送时， 若接收到 的短信没有嵌入数字水印信息， 则可以成功发送短信， 若接收到的短信嵌 有数字水印信息， 则发送时会有相应的提示信息。 The short message sending module is mainly used to implement the function of sending short messages. As the sender of the short message, if the digital watermark information is already embedded in the short message, the short message will be sent with the digital watermark embedded in the short message. If the digital watermark information is not embedded in the short message, the ordinary short message is processed when sending the message; The receiving party, when editing the received short message and then transmitting, if the received short message does not embed the digital watermark information, the short message can be successfully sent. If the received short message is embedded with the digital watermark information, the corresponding message will be sent. Tip message.
短信转发模块， 用于直接进行短信转发时， 若确定该短信是普通短信， 则可以成功进行转发， 若确定该短信中嵌有数字水印信息， 则转发时会有 相应的提示信息。 The short message forwarding module is used for direct message forwarding. If the short message is determined to be a normal short message, the message forwarding module can successfully forward the message. If it is determined that the digital watermark information is embedded in the short message, the corresponding prompt message will be sent when forwarding.

When you select "Yes", enter the encryption password. When you select "No", you do not need to set it. Once the encrypted password is set, the sender can successfully send the text message.
第四步、 短信接收终端收到短信发送终端发来的短信， 对短信内容进 行查看和阅读。 In the fourth step, the short message receiving terminal receives the short message sent by the short message sending terminal, and views and reads the short message content.
第五步、 短信接收终端对收到的短信进行转发， 点击转发按钮时弹出 提示信息； 或短信接收终端对接收到的短信编辑后再进行发送， 点击发送
时弹出提示信息。 Step 5: The short message receiving terminal forwards the received short message, and pops up a prompt message when the forward button is clicked; or the short message receiving terminal sends the received short message after editing, and then clicks to send A prompt message pops up.
第六步、 选择 "是" 后， 弹出提示框， 需要输入解密密码， 短信接收 方不知道解密密码， 无法对数字水印信息做进一步的解密处理。 In the sixth step, after selecting "Yes", a prompt box is displayed, and the decryption password needs to be input. The SMS receiver does not know the decryption password, and cannot perform further decryption processing on the digital watermark information.
第七步、 如果接收方知道解密密码， 输入成功的解密密码后， 仍需对 嵌入在短信中的数字水印信息做解密处理， 短信接收方不知道发送方在短 信中嵌入了何种水印加密算法， 仍无法对嵌入数字水印信息后的短信进行 解密处理。 Step 7: If the receiving party knows the decryption password, after inputting the successful decryption password, the digital watermark information embedded in the short message still needs to be decrypted, and the short message receiver does not know what watermark encryption algorithm is embedded in the short message by the sender. , it is still impossible to decrypt the SMS after embedding the digital watermark information.
图 3是本发明实施例提供的数字水印模块示意图， 如图 3所示， 数字 水印模块嵌入在短信保护单元中， 用户作为短信发送方时， 根据在短信保 护单元中设置的变量水印 （WaterMark ) 的取值判断是否嵌入水印， WaterMark=l表示嵌入水印， WaterMark=0表示没有嵌入水印， 没有嵌入数 字水印的短信按普通短信处理。 用户在发送短信时可以选择使用数字水印 或不使用数字水印， 默认方案是两种情况中的一种， 即不使用数字水印。 当选择使用数字水印对短信进行加密时， 让用户选择数字水印信息， 手机 终端中默认的提供了一些信息， 主要有图片、 文本、 数字等， 用户还可以 选择摄像机拍摄的图片或视频作为数字水印信息。 数字水印信息选择完毕 后， 用户选择水印嵌入算法， 手机终端中提供了多种经典的水印嵌入算法 供用户选择， 主要有鲁棒性算法、 脆弱性算法等， 可以选择其中的某一种 算法将数字水印信息嵌入到短信中。 水印嵌入算法选择完毕后， 用户成功 地将数字水印信息嵌入到短信中， 对于纯文本短信， 水印嵌入在短信的某 一行中，假如：输入的纯文本短信是 n行，那么将水印信息可以嵌入在第 [n/2] 行的文字中， 其中， []为取整符号。 若短信的每一行可以输入 m个字， 则 嵌入在纯文本短信中的水印的中心位置在短信的第 [n/2]行的第 [m/2]个字的 位置处。 对于含有音频、 视频和图片等载体的信息， 数字水印信息主要嵌 入在这些载体中。 用户作为短信接收方时， 数字水印模块通过提供禁止短
信转发函数禁止短信接收方转发所述嵌有数字水印信息的短信。 图 4是本发明实施例提供的短信发送终端发送短信流程图， 如图 4所 示， 用户在编辑一条短信后， 可以选择是否在短信中嵌入数字水印信息。 当选择不嵌入数字水印信息时， 所述短信按照普通短信处理， 经由短信发 送模块发送出去。 当选择嵌入数字水印信息时， 根据用户选择的数字水印 信息和水印嵌入算法， 将数字水印信息嵌入到短信中。 成功嵌入数字水印 信息后， 手机终端弹出提示信息 "对于嵌入的数字水印信息是否要进行加 密设置"， 提示用户对所述数字水印信息进行加密处理。 当用户选择 "是" 时， 输入加密密码， 点击确定； 当用户选择 "否" 时， 无需进行相关信息 设置。 最后， 用户点击发送， 嵌入数字水印信息的短信经由短信发送模块 发送至短信接收终端。 3 is a schematic diagram of a digital watermarking module provided by an embodiment of the present invention. As shown in FIG. 3, a digital watermarking module is embedded in a short message protection unit, and when a user acts as a short message sender, according to a variable watermark (WaterMark) set in the short message protection unit. The value of the value is judged whether the watermark is embedded, WaterMark=l indicates that the watermark is embedded, WaterMark=0 indicates that the watermark is not embedded, and the short message without the embedded digital watermark is processed by the ordinary short message. The user can choose to use the digital watermark or not use the digital watermark when sending the short message. The default scheme is one of two situations, that is, the digital watermark is not used. When the digital watermark is selected to encrypt the short message, the user is allowed to select the digital watermark information. The default information provided in the mobile terminal includes some pictures, text, numbers, etc. The user can also select the picture or video captured by the camera as the digital watermark. information. After the digital watermark information is selected, the user selects the watermark embedding algorithm, and the mobile terminal provides a variety of classic watermark embedding algorithms for the user to select, mainly including robust algorithms, vulnerability algorithms, etc., one of which may be selected. The digital watermark information is embedded in the short message. After the watermark embedding algorithm is selected, the user successfully embeds the digital watermark information into the short message. For the plain text message, the watermark is embedded in a certain line of the short message. If the input plain text message is n lines, the watermark information can be embedded. In the text of line [n/2], where [] is a rounding symbol. If m words can be input for each line of the short message, the center position of the watermark embedded in the plain text message is at the position of the [m/2]th word of the [n/2]th line of the short message. For information containing carriers such as audio, video and pictures, digital watermark information is primarily embedded in these vectors. When the user acts as a short message receiver, the digital watermark module provides a prohibition by short The letter forwarding function prohibits the short message receiver from forwarding the short message embedded with the digital watermark information. FIG. 4 is a flow chart of sending a short message by a short message sending terminal according to an embodiment of the present invention. As shown in FIG. 4, after editing a short message, the user may select whether to embed digital watermark information in the short message. When the digital watermark information is not embedded, the short message is processed according to the ordinary short message and sent out through the short message sending module. When the embedded digital watermark information is selected, the digital watermark information is embedded into the short message according to the digital watermark information and the watermark embedding algorithm selected by the user. After the digital watermark information is successfully embedded, the mobile terminal pops up a prompt message "whether or not the embedded digital watermark information is to be encrypted", prompting the user to encrypt the digital watermark information. When the user selects "Yes", enter the encryption password and click OK; when the user selects "No", no relevant information setting is required. Finally, the user clicks to send, and the short message embedded in the digital watermark information is sent to the short message receiving terminal via the short message sending module.
图 5是本发明实施例提供的短信接收终端转发短信流程图， 如图 5所 示， 短信接收终端收到来自短信发送终端的短信后， 无论短信中是否嵌入 数字水印信息， 接收方都可以通过短信接收终端正常阅读和查看所收到的 短信。 当短信接收终端对收到的短信进行转发或编辑短信内容后发送时， 选择需要进行转发的联系人， 点击转发按钮。 短信接收终端判断所述短信 中是否嵌入数字水印信息， 当判断结果为没有嵌入数字水印信息时， 短信 可以成功进行转发； 当判断结果为已经嵌入数字水印信息时， 对该短信进 行转发或编辑后发送时会调用禁止短信转发函数， 系统弹出提示 "短信已 嵌入数字水印并设置加密密码， 无法进行转发， 需要输入解密密码"。 短信 接收终端无法破解解密密码， 则会提示 "短信已嵌入数字水印， 不能进行 转发， 谢谢合作"。 若短信接收终端破解了解密密码， 并成功输入， 输入成 功后仍会调用禁止短信转发函数， 提示 "短信已嵌入数字水印， 不能进行 转发， 谢谢合作"。 由于短信接收终端无法知道短信发送终端在短信中嵌入 了何种水印算法， 就不能对收到的短信进行转发。
其中， 设置的加密密码起到了对短信进行双重保护作用。 采用双重保 护功能能够确保短信从发送方发出后， 接收方在收到短信后不能将短信进 行转发或进行编辑后发送， 从而保护了发送方的隐私信息和对短信内容的 版权。 如果接收端将接收到的多媒体信息传递到网络上， 发送方也可以根 据嵌入在多媒体信息中的数字水印信息来保护自己的版权。 5 is a flow chart of forwarding a short message by a short message receiving terminal according to an embodiment of the present invention. As shown in FIG. 5, after receiving a short message from a short message sending terminal, the short receiving terminal can pass the digital watermark information in the short message. The short message receiving terminal normally reads and views the received short message. When the short message receiving terminal forwards the received short message or edits the short message content, select the contact that needs to be forwarded, and click the forward button. The short message receiving terminal determines whether the digital watermark information is embedded in the short message, and when the judgment result is that the digital watermark information is not embedded, the short message can be successfully forwarded; when the judgment result is that the digital watermark information is embedded, the short message is forwarded or edited When sending, the SMS forwarding function is disabled. The system prompts “SMS has embedded digital watermark and set encryption password. It cannot be forwarded and needs to enter the decryption password”. The SMS receiving terminal cannot crack the decryption password, and it will prompt "The SMS has been embedded in the digital watermark and cannot be forwarded. Thank you for your cooperation." If the short message receiving terminal cracks the decryption password and successfully inputs it, the SMS forwarding function will still be called after the input is successful, prompting that "the SMS has been embedded in the digital watermark and cannot be forwarded, thank you for cooperation." Since the short message receiving terminal cannot know which watermarking algorithm is embedded in the short message by the short message transmitting terminal, the received short message cannot be forwarded. Among them, the set encryption password plays a dual protection role for the short message. The dual protection function ensures that after the SMS is sent from the sender, the recipient cannot forward or edit the SMS after receiving the SMS, thus protecting the sender's private information and the copyright of the SMS content. If the receiving end transmits the received multimedia information to the network, the sender can also protect the copyright according to the digital watermark information embedded in the multimedia information.
综上所述， 本发明具有以下技术效果： In summary, the present invention has the following technical effects:
本发明为克服短信发送终端发出的短信被短信接收终端接收后， 仍有 可能将所述短信进行转发或编辑后进行发送的问题和缺陷， 以及接收方将 接收到的多媒体信息上传到网络中被多次转载的现状， 通过在短信中嵌入 数字水印， 有效防止短信转发， 加强对手机用户私有信息的保护。 In order to overcome the problems and defects that the short message sent by the short message sending terminal is received by the short message receiving terminal, the short message may still be forwarded or edited, and the receiving party uploads the received multimedia information to the network.
