For example, the smart terminal described in the present invention may include mobiles such as mobile phones, smart phones, notebook computers, PDAs (Personal Digital Assistants), PADs (Tablets), PMPs (Portable Multimedia Players), navigation devices, smart watches, and the like. Terminals, as well as fixed terminals such as digital TVs, desktop computers, and the like. Hereinafter, the present invention will be described on the assumption that the smart terminal is a smart phone. However, those skilled in the art will appreciate that configurations in accordance with embodiments of the present invention can be applied to fixed type terminals in addition to components that are specifically for mobile purposes.
-步骤S100：开启所述智能终端内的一相册应用，获取所述相册应用内的一图像。- Step S100: Turn on an album application in the smart terminal to acquire an image in the album application.
由于需要从智能手机的相册或图库中调取图像，涉及到智能手机的相册或图库中的深层内容，因此，需要向智能手机的相册或图库发出权限或路径请求，获取读取与复制智能手机的相册或图库中的图像的权限，之后从智能手机的相册或图库中载入用户指定的某一图像。Due to the need to retrieve images from the smartphone's photo album or gallery, which involves the deep content of the smartphone's photo album or gallery, it is necessary to issue a permission or path request to the smartphone's photo album or gallery to obtain a read and copy smartphone. The permissions of the image in the album or gallery, and then load a user-specified image from the smartphone's album or gallery.
-步骤S200：提取所述图像内的图形标识符或色彩参数；- step S200: extracting a graphic identifier or a color parameter within the image;
-步骤S300：转换所述图形标识符或色彩参数至一第一字符；- step S300: converting the graphic identifier or color parameter to a first character;
步骤S200-300，将用户指定的该图像进行参数提取，针对不同类型图像的参数提取与转换有多种形式：Step S200-300, the parameter specified by the user is extracted, and the parameter extraction and conversion for different types of images have various forms:
(1)用户指定的图像中直接包含了条形码、二维码、文字信息、数字信息、字母信息等，可以直接将条形码、二维码转换为字符，或直接提取图像中的文字信息、数字信息、字母信息等，将其转化为二进制或十进制数据。(1) The image specified by the user directly includes the barcode, the two-dimensional code, the text information, the digital information, the letter information, etc., and the barcode or the two-dimensional code can be directly converted into a character, or the text information and the digital information in the image can be directly extracted. , letter information, etc., convert it to binary or decimal data.
在上述需要提取的情况下，需要采用数字图像处理技术，包括图像变换、图像增强技术等，并结合图像识别技术。如，用户指定的图像中直接包含了“111”三个数字，则可以直接提取图像中的数字“111”。首先，通过图像变换实现模拟图像到数字图像的转换，方便后续的处理，图像变换的方法主要有傅里叶变换、沃尔什-阿达玛变换以及离散卡夫纳-勒维变换。然后，采用图像增强技术，强化边缘，使图像中数字“111”的轮廓清晰，并对数字“111”进行分割与提取。可以根据图像中像素的亮度及颜色进行分割，包括灰度阀值分割法、区域生长分割法、边缘分割法以及基于直方图递归分割法，均可实现图像的分割，从而达到提取数字“111”的目的。In the case where the above extraction is required, digital image processing technology, including image transformation, image enhancement technology, etc., is required, and combined with image recognition technology. For example, if the user-specified image directly contains three numbers of "111", the number "111" in the image can be directly extracted. Firstly, the conversion of analog image to digital image is realized by image transformation, which facilitates subsequent processing. The methods of image transformation mainly include Fourier transform, Walsh-Hadamard transform and discrete Kafner-Levy transform. Then, using image enhancement technology, the edges are strengthened to make the outline of the number "111" in the image clear, and the number "111" is segmented and extracted. It can be segmented according to the brightness and color of the pixels in the image, including gray threshold segmentation method, region growing segmentation method, edge segmentation method and histogram recursive segmentation method, which can realize image segmentation, thus extracting the number "111". the goal of.
(2)用户指定的图像中未包含二维码、条形码、文字信息、数字信息、字母信息等可以直接转换为字符的信息，则可以提取图像的色彩参数，例如图像的灰度、图像的RGB分量值等，将其转换为二进制数据。(2) The image specified by the user does not include the QR code, barcode, text information, digital information, letter information, etc., which can be directly converted into characters, and the color parameters of the image, such as the gray level of the image and the RGB of the image, can be extracted. Component values, etc., convert them to binary data.
参考图3，在一优选实施例中，S200：提取所述图像内的图形标识符或色彩参数的步骤，及S300：转换所述图形标识符或色彩参数至一第一字符的步骤包括：Referring to FIG. 3, in a preferred embodiment, S200: the step of extracting a graphic identifier or a color parameter within the image, and S300: the step of converting the graphic identifier or color parameter to a first character comprises:
对所述图像进行色彩分析，提取所述图像的R分量值；Performing color analysis on the image to extract an R component value of the image;
将所述R分量值转化为一第一二进制数据作为所述第一字符。 Converting the R component value into a first binary data as the first character.
上述实施例即是对图像中的色彩进行分析，形成RGB的分量图，取R分量值，将R分量值转换为二进制数据。The above embodiment analyzes the color in the image to form a component map of RGB, takes the R component value, and converts the R component value into binary data.
-步骤S400：接收一用户向所述智能终端输入的一语音信息；- Step S400: receiving a voice message input by a user to the smart terminal;
-步骤S500：转换所述语音信息至一第二字符；- Step S500: converting the voice information to a second character;
本发明的图像存储方法，提供给用户的加密方式有多种，用户可自行选择。用户向智能手机输入的操作信息不限于语音信息，也可以是文字信息、数字信息、字母信息等，也可是通过现场录音或直接载入音频、视频等的方式。用户可以选择至少一种信息形式进行载入，载入的信息形式越多，加密程度越高，解密也更复杂。In the image storage method of the present invention, there are various encryption methods provided to the user, and the user can select oneself. The operation information input by the user to the smart phone is not limited to voice information, and may also be text information, digital information, letter information, etc., or may be recorded by live recording or directly loading audio, video, or the like. The user can select at least one form of information to load, and the more information forms that are loaded, the higher the degree of encryption and the more complicated the decryption.
以下以语音信息为例，对本发明进一步说明。The present invention will be further described below by taking voice information as an example.
参考图4，在一优选实施例中，S500：转换所述语音信息至一第二字符的步骤包括：Referring to FIG. 4, in a preferred embodiment, S500: the step of converting the voice information to a second character includes:
对所述语音信息进行预加重数字滤波处理及加窗分帧处理；Performing pre-emphasis digital filtering processing and windowing framing processing on the voice information;
对预加重数字滤波处理及加窗分帧处理后的每一帧所述语音信息进行声学特征提取，形成所述语音信息的观察序列矩阵；And performing acoustic feature extraction on the voice information of each frame after the pre-emphasis digital filtering process and the windowed frame processing to form an observation sequence matrix of the voice information;
将所述观察序列矩阵解析为文本信息，并转化为一第二二进制数据作为所述第二字符。The matrix of observation sequences is parsed into text information and converted into a second binary data as the second character.
上述实施例中，由于语音信息中不仅包含有文字内容，还有音色、音调、环境中的声音等，难以复原，因此，需要提取其中的文字内容。对于用户输入的语音信息的提取与转换，需要借助语音识别技术：In the above embodiment, since the voice information includes not only text content but also timbre, pitch, sound in the environment, and the like, it is difficult to recover, and therefore, it is necessary to extract the text content therein. For the extraction and conversion of voice information input by the user, it is necessary to use voice recognition technology:
(1)格式转换：对于常见的语音信息格式，如mp3等格式，均为压缩格式，需要先转为非压缩的纯波形文件来进行后续处理，如Windows PCM文件，也就是俗称的wav文件。(1) Format conversion: For common voice information formats, such as mp3 format, all are compressed formats, which need to be converted to uncompressed pure waveform files for subsequent processing, such as Windows PCM files, also known as wav files.
(2)静音切除：进行语音信息的声音识别前，需要将首尾段的静音切除，降低对后续步骤造成的干扰，上述静音切除的操作成为VAD，采用信号处理技术。(2) Silent resection: Before performing voice recognition of voice information, it is necessary to cut off the mute of the first and last segments to reduce the interference caused by the subsequent steps. The above mute resection operation becomes VAD, and signal processing technology is adopted.
(3)预加重数字滤波：预加重的目的是使语音信号的高频特性更加突现。一般是通过传递函数是高通数字滤波器来实现。(3) Pre-emphasis digital filtering: The purpose of pre-emphasis is to make the high-frequency characteristics of the speech signal more prominent. This is usually done by passing the transfer function to a high-pass digital filter.
假设：第n时刻的语音采样值为x(n)，则经过预加重处理后的结果是y(n)＝x(n)-ax(n-1)；其中，a为预加重系数，一般是0.9～1.0之间，通常取0.98。Assume that the value of the speech sample at the nth time is x(n), and the result after the pre-emphasis processing is y(n)=x(n)-ax(n-1); where a is the pre-emphasis coefficient, generally It is between 0.9 and 1.0, usually 0.98.
(4)加窗分帧：预加重数字滤波处理后，下面就是进行加窗分帧处理，语音信号具有短时平稳性(10ms一30ms内可以认为语音信号近似不变)，这样就可以把语音信号分为一些短段来进行处理。语音信号的分帧是采用可移动的有限长度的窗口进行加权的方法来实现的。一般每秒的帧数约为33～100帧，视情况而定。一般的分帧方法为交叠分段的方法，前一帧和后一帧的交叠部分称为帧移，帧移与帧长的比值一般为0～0.5。(4) Windowing framing: After pre-emphasis digital filtering processing, the following is the windowing and framing processing, the speech signal has short-term stability (the speech signal can be considered to be approximately unchanged within 10ms to 30ms), so that the speech can be The signal is divided into short segments for processing. Framing of speech signals is accomplished by weighting a finite length window that is movable. Generally, the number of frames per second is about 33 to 100 frames, as the case may be. The general framing method is a method of overlapping segments. The overlapping portion of the previous frame and the next frame is called frame shift, and the ratio of frame shift to frame length is generally 0-0.5.
(5)声学特征提取：分帧后，语音信息就变成很多短段，但其波形在时域上几乎没有描述能力，因此需要将波形进行变换。常见的一种变换方法时提取MFCC特征，根据人耳的生理特性，把每一帧波形变成一个多维向量，每个向量包含了这帧语音的内容信息，上述过程即为声学特征提取。实际应用中，声学特征不限于MFCC，本发明不对此作出限制。(5) Acoustic feature extraction: After framing, the speech information becomes a lot of short segments, but its waveform has almost no description ability in the time domain, so the waveform needs to be transformed. A common transformation method extracts MFCC features. According to the physiological characteristics of the human ear, each frame waveform is transformed into a multi-dimensional vector. Each vector contains the content information of the speech of the frame. The above process is the acoustic feature extraction. In practical applications, the acoustic characteristics are not limited to the MFCC, and the invention is not limited thereto.
(6)观察序列：至此，将语音信息转化为一个M行(M为声学特征为维数)、N列(N为总帧数)的矩阵，称之为观察序列。(6) Observation sequence: Up to this point, the speech information is converted into a matrix of M rows (M is an acoustic feature as a dimension) and N columns (N is a total number of frames), which is called an observation sequence.
(7)文本转换：将上述观察序列转换为文本信息。(7) Text conversion: Convert the above observation sequence into text information.
-步骤S600：将所述第一字符与所述第二字符结合，生成一图像密码；- Step S600: combining the first character with the second character to generate an image password;
-步骤S700：使用所述图像密码对所述图像加密。Step S700: Encrypt the image using the image password.
确定提取的图像参数及用户输入的语音信息转化后得到的两者的字符数据的运算规则，如乘法、除法等运算规则，对提取的图像参数及用户输入的语音信息转化得到的字符数据进行运算，获取图像密码，并使用该图像密码对图像加密。 The operation rule for determining the extracted image parameters and the character data obtained by the conversion of the voice information input by the user, such as multiplication and division, is used to calculate the extracted image parameters and the character data converted by the user-entered voice information. , get the image password, and use the image password to encrypt the image.
参考图5，在一优选实施例中，S700：使用所述图像密码对所述图像加密的步骤包括：Referring to FIG. 5, in a preferred embodiment, S700: the step of encrypting the image using the image password includes:
选取所述图像的部分区域作为待加密区域；Selecting a partial region of the image as the region to be encrypted;
使用所述图像密码对所述图像的所述待加密区域加密。The area to be encrypted of the image is encrypted using the image password.
本发明提供的图像存储方法，不仅可以对整幅图像进行加密，还可以基于户选择或自动识别对图像的局部区域进行加密处理，不仅可以对一幅图像进行加密，还可以基于户选择或自动识别多幅图像进行加密处理。The image storage method provided by the invention can not only encrypt the entire image, but also encrypt the local area of the image based on household selection or automatic identification, and can not only encrypt one image, but also select based on household or automatically. Identify multiple images for encryption.
例如，用户直接选取图像内的一部分区域作为待加密区域进行加密，或者用户直接选取相册内的多个图像，进行加密。又如，在智能手机内增设一人脸识别装置，用以识别某一图像中的人脸区域，或者，用以识别相册中具有人脸区域的图像。For example, the user directly selects a part of the area in the image as the area to be encrypted for encryption, or the user directly selects multiple images in the album to perform encryption. For another example, a face recognition device is added to the smart phone to identify a face region in an image, or to identify an image having a face region in the album.

-步骤S900：转换所述当前语音信息至一第三字符；- Step S900: converting the current voice information to a third character;
-步骤S1000：将所述第一字符与所述第三字符结合，生成一当前图像密码；- Step S1000: combining the first character with the third character to generate a current image password;

-步骤S1200：当所述当前图像密码与所述图像密码匹配时，解密所述图像。- Step S1200: Decrypt the image when the current image password matches the image password.
本发明提供的图像存储方法，其解密过程中，图像参数的提取是固定不变的，用户输入的语音信息是变化的。解密时，由用户再次输入语音信息，输入的语音信息与原语音信息相同，即再次提取并计算得到的密码与加密时生成的密码相同即可解密成功。The image storage method provided by the present invention, in the decryption process, the extraction of the image parameters is fixed, and the voice information input by the user is changed. When decrypting, the voice information is input again by the user, and the input voice information is the same as the original voice information, that is, the password extracted again and calculated is the same as the password generated during encryption, and the decryption is successful.
如上所述的，用户输入操作信息时，不限于语音信息，可输入多种类型的操作信息，输入的操作信息类型越多，加密程度越高，解密更复杂。但多个操作信息容易混淆，同时忘记输入的是什么操作信息或哪个操作信息的可能性也更大，因此，用户可根据需求选择输入的几种操作信息之间的逻辑关系是逻辑或还是逻辑与。As described above, when the user inputs the operation information, it is not limited to the voice information, and various types of operation information can be input. The more types of operation information input, the higher the degree of encryption, and the more complicated the decryption. However, multiple operational information is confusing, and it is more likely to forget what operational information or operational information is entered. Therefore, the logical relationship between several operational information that the user can select and input according to requirements is logical or logical. versus.
用户选择逻辑或时，在解密时，用户提供其之前输入的任意一个操作信息均可解密，加密时，将各操作信息所转化的数据分别与被图像所转化的数据进行运算，获取多个密码，多个密码之间的逻辑关系为或；When the user selects the logical OR, when the user decrypts, any one of the operation information previously input by the user can be decrypted. When encrypting, the data converted by each operation information is respectively calculated with the data converted by the image to obtain multiple passwords. , the logical relationship between multiple passwords is or;
用户选择逻辑与时，在解密时，用户必须同时提供其之前输入的所有操作信息方可解密，加密时，将各操作信息所转化的数据一同与被提醒所转化的数据进行运算，获取一个密码值。When the user selects the logical AND, when decrypting, the user must simultaneously provide all the operation information input by the user before decrypting. When encrypting, the data converted by each operation information is calculated together with the data converted by the reminder to obtain a password. value.
