[0056] Before the embodiments of the present application are described in detail, first, some nouns and terms involved in the embodiments of the present application are described, and the nouns and terms involved in the embodiments of the present application are applicable to the following explanations.

[0057] 1) Multiple Encryption Algorithms: Also known as multiple strength encryption or cascading encryption, it involves encrypting data multiple times using the same or different encryption algorithms. This method can improve the complexity and security of encrypted data by applying the encryption process multiple times.

[0058] 2) Text Recognition Module: This is a software component or system that can recognize and process text information, commonly used to extract textual content from images, scanned documents, or handwritten input.

[0059] 3) Iris Matching Pairing: Iris recognition technology is an advanced biometric technology that uses the unique features of an individual's iris in the eye for identity verification. This technology confirms the identity of individuals by analyzing the color, texture, and other unique details of the iris of the eye, as each person's iris pattern is unique, just like fingerprints, which makes iris recognition a very accurate and secure identification method.

[0060] 4) Decryption Key: The decryption key is a specific string or numerical sequence used to unlock encrypted data or information, and it is paired with the encryption key to achieve information security in the encryption and decryption process.

[0061] 5) Automatic Decryption: Refers to the process of automatically decrypting encrypted text without human intervention to obtain the original information through software or hardware systems when certain conditions are met, without the need for users to manually input decryption instructions to automatically convert back to the original text.

[0062] In related technologies, the communication security of electronic mailboxes mainly relies on traditional encryption technology. These encryption technologies can protect the confidentiality of email content to some extent during transmission, but when faced with complex and variable network attacks and cracking methods, their security often seems inadequate. Traditional single encryption algorithms often have the risk of being cracked, and once cracked, the email content will be exposed. In addition, with the improvement of computer computing power and the development of cracking technology, the security of traditional encryption algorithms is constantly being challenged. The encryption communication methods in related technologies mostly have the problems of insufficient security, complex operation, low efficiency, etc., and are difficult to meet the actual needs of electronic mailbox communication security.

[0063] For example, the sender creates a new email in the email client, enters the email address of the recipient in the email, ensures that the recipient has provided the key or public key required for encrypted email, fills in the content to be sent in the email, encrypts the email content, which is usually done automatically, and the email client uses the pre-configured key or public key to encrypt the email. After completing the composition and encryption of the email, click the send button to send the email. After receiving the encrypted email, the recipient needs to use the corresponding private key or decryption tool to decrypt the email, and the recipient needs to have the corresponding decryption key and the corresponding decryption software or tool. This method only encrypts the email when it is sent, and when the email is decrypted, the corresponding decryption key and the corresponding decryption software or tool are needed, which is very cumbersome and inconvenient to decrypt, and has the problems of insufficient security, complex operation, low efficiency, etc., and it is difficult to meet the actual needs of electronic mailbox communication security.

[0064] Therefore, the embodiments of the present application provide an electronic mailbox communication method, system, device and medium. The scheme obtains an email and a biometric image, performs content encryption processing on the email to obtain a first encrypted email, and can preliminarily encrypt the email content to ensure the basic security of the email in the transmission process. In addition, the scheme performs verification encryption processing on the first encrypted email according to the biometric image to obtain a second encrypted email, and sends the second encrypted email to a target electronic mailbox. The scheme encrypts the email based on biometric information to improve the security of email communication. Furthermore, the scheme performs address comparison and identity verification processing on the second encrypted email according to the target electronic mailbox to obtain a first encrypted email, and performs automatic decryption processing on the first encrypted email to obtain an email. The scheme can improve the efficiency and security of encrypted email communication by intelligently and automatically encrypting and decrypting the email.

[0068] Figure 1 is an optional flowchart of an electronic mailbox communication method provided by the embodiments of the present application,Figure 1 The method in the method can include but not limited to including steps S101 to S105.

[0069] Step S101, obtaining an email and a biometric image;

[0070] Step S102, performing content encryption processing on the email to obtain a first encrypted email;

[0071] Step S103, performing verification encryption processing on the first encrypted email according to the biometric image to obtain a second encrypted email, and sending the second encrypted email to a target email box;

[0072] Step S104, performing address comparison and identity verification processing on the second encrypted email according to the target email box to obtain the first encrypted email;

[0073] Step S105, performing automatic decryption processing on the first encrypted email to obtain the email.

[0074] The steps S101 to S105 shown in the embodiments of the present application obtain an email by a computer or other user terminal obtaining the email content to be sent by the user, and obtain a biometric image by a database or the like. The biometric image is an image containing biometric information, and the biometric information includes fingerprints, irises, etc., and has extremely high uniqueness and non-replicability. Then, the email content is automatically encrypted by using a character recognition module, the key words in the email are recognized, and the key information is automatically encrypted to obtain a first encrypted email. Next, the first encrypted email is verified and encrypted according to the biometric information in the biometric image to obtain a second encrypted email, and the second encrypted email is sent to a target email box. The embodiments of the present application use the biometric information as a key, so that only the legal recipient can decrypt and read the email content. This encryption method based on biometric information not only improves the security of encryption, but also provides a more convenient operation experience for the user. Finally, the second encrypted email is compared with the address and verified by the target email box, and the first encrypted email is obtained after the comparison and verification. It should be noted that when the comparison and verification result is not passed, the system will immediately start an automatic destruction mechanism, which can destroy the email content in a very short time to ensure that the email cannot be leaked or misused. After the comparison and verification, the first encrypted email is automatically decrypted to obtain an email. The embodiments of the present application can improve the security and reliability of the email communication process by using multiple encryption algorithms to encrypt the email content in multiple levels, protect the privacy and information security of the user, and build a multi-level and multi-dimensional security protection system for the security risks existing in the email communication, improve the confidentiality and integrity of the email, and fully protect the privacy and information security of the user.

[0075] In step S101 of some embodiments, an email can be obtained by a computer, a mobile terminal or the like, and the email is the content input by the user, which can be generated by manual input or voice input. The biometric image can be image data pre-stored in a database, or can be obtained by other means, such as receiving an image sent by the recipient, such as a specific image provided by the recipient, such as an eye photo, etc.

[0076] Please refer to Figure 2 In some embodiments, step S102 can include but is not limited to steps S201 to S202:

[0077] Step S201, performing keyword recognition processing on the email to obtain a keyword set;

[0078] Step S202, character encryption processing is performed on the keyword set to obtain the first encrypted email.

[0079] In the embodiment of the present application, the content of the email is automatically recognized by the character recognition module. The keywords in the email are automatically encrypted to obtain the first encrypted email. The character recognition module can be constructed by using a pre-processing model and other neural network models. It can extract text content from images, scanned documents or handwritten inputs, and automatically encrypt sensitive information. By automatically recognizing and encrypting the title, body or attachments in the email, the possibility of email being stolen or tampered with during transmission can be reduced. The character recognition module identifies and judges by keyword recognition. The keywords include time, place, event and person, etc. After identifying the relevant keyword set, the identified keyword set is subjected to character encryption processing. The user does not need to manually select which information needs to be encrypted. The system automatically judges and processes the email content to provide more intelligent services to the user. The content encryption processing of the email in the embodiment of the present application can improve the accuracy and efficiency of encryption, greatly reducing the user's operation burden.

[0080] Please refer to Figure 3 In step S202 of some embodiments, the character encryption processing on the keyword set to obtain the first encrypted email includes the following steps:

[0081] Step S301, grouping processing is performed on the keyword set to obtain a keyword grouping;

[0082] Step S302, combining processing is performed on the characters in the keyword grouping according to the character order to obtain the first encrypted email.

[0083] In the embodiment of the present application, after identifying the keyword set, the keyword set is grouped to obtain a plurality of keyword groupings. Specifically, the keyword set can be divided into N groups, and N is a positive integer greater than or equal to 2. Then, each character in the keyword grouping is combined. In the embodiment of the present application, the first character in each group is combined to form the first part of the ciphertext, the second character is combined to form the second part of the ciphertext, and then the combination is continuously recombined to obtain the first encrypted email after encryption. The expression of character encryption is as follows:

[0084] e π (x1, x2…xm) = (x π(1) …x π(m) );

[0085] d π (y1, y2…ym) = (yπ(1) …y π(m) );

[0086] In the formula, e and d are the permutation of the password, xm is the mth encrypted character, ym is the mth decrypted character, π is the key, and m is the number of groups. It is conceivable that the embodiments of the present application can also optimize the user interface, so that the user can easily set and adjust the encryption parameters, such as the identification criteria of the keywords and the selection of the character encryption algorithm, and can automatically identify the sensitivity of the email content and recommend appropriate encryption strategies according to the sensitivity. The embodiments of the present application identify sensitive information or key data through the character recognition module, and encrypt the characters according to the security requirements of these information, and can also select different encryption algorithms according to the actual requirements to flexibly combine, so as to accurately match the requirements of various security scenarios.

[0087] Please refer to Figure 4 In step S103 of some embodiments, the second encrypted email is obtained by verifying and encrypting the first encrypted email according to the biometric image, including the following steps:

[0088] Step S401: image preprocessing is performed on the biometric image to obtain a preprocessed image;

[0089] Step S402: biometric feature extraction processing is performed on the preprocessed image to obtain an iris feature;

[0090] Step S403: data conversion processing is performed on the iris feature to obtain encrypted data;

[0091] Step S404: data encryption processing is performed on the first encrypted email according to the encrypted data to obtain the second encrypted email.

[0092] In the embodiments of the present application, the first encrypted email can be verified and encrypted according to a biometric image, and a second encrypted email is obtained by taking biometric information as a key, wherein the biometric information includes fingerprints, irises, etc. The iris is a circular part between the black pupil and the white sclera, and contains many details such as interlaced spots, filaments, crowns, stripes, and recesses. These features remain unchanged throughout the life after being formed in the fetal development stage, and these features determine the uniqueness of the iris features and the uniqueness of the identity recognition. Therefore, the iris features of the eyes can be taken as the identity recognition object of each person, and the encryption processing based on the iris features is taken as an example for description. Specifically, the embodiments of the present application pre-process the biometric image, including gray value processing, smoothing processing, and normalization processing, and extract the biometric features from the obtained pre-processed image, extract the iris features in the image, convert the features into data form, and encrypt to obtain the second encrypted email. When the biometric image is grayed, the maximum value of red, green, and blue in each pixel of the color image is taken as the gray value of the pixel. The smoothing processing is processed by the mean filtering method, an m*n template is generated, m and n are positive integers greater than 0, all elements in the template are assigned to 1, the center of the template is overlapped with the pixel points of the image, all deposits are added and assigned to the corresponding pixel of the template center, so as to remove the noise points in the image. The linear normalization processing is adopted for the normalization processing, and the expression of the normalization calculation formula is as follows:

[0093] P=(q-m1) / (m2-m1);

[0094] wherein q is the data before normalization, P is the data after normalization, m1 is the minimum value in the data set, and m2 is the maximum value in the data set. Normalization is a data processing technique mainly used to simplify calculations and improve the convergence speed of algorithms, which can simplify the calculation process, map the data to a specific range, simplify the subsequent calculation process, and improve the convergence speed of the algorithm to avoid the problem of slow convergence speed caused by uneven data distribution. The embodiments of the application can also perform data scaling and feature scaling preprocessing on the biometric image. Data scaling can scale the entire data set to a specified range. The minimum-maximum scaling method can be used to scale the data to the range of [0, 1] or [-11]. The square root transformation can also be used to take the square root of the data as the new feature value. The logarithmic transformation can also be used to take the data as the new feature value with a base of 10 or a natural logarithm. Feature scaling refers to scaling each feature individually to better train and predict machine learning algorithms. Feature scaling methods include feature value conversion, which converts feature values to a power form with a certain base; standardization, which converts feature values to a standardized form so that the mean of each feature is 0 and the standard deviation is 1; and decimal place normalization, which normalizes feature values to a certain number of decimal places, usually by rounding or rounding. After obtaining the preprocessed image, biometric feature extraction processing is performed on the preprocessed image to obtain iris features, wherein the iris features include concave points, radial lines, pigment points, pupil areas, and spots. By converting the recognized iris features into data encoding, wavelet transformation is used for encoding processing to obtain encrypted data. Finally, the first encrypted email is processed based on the encrypted data to obtain the second encrypted email. Specifically, the embodiments of the application can create a unique identifier by extracting the texture features of the iris. Based on the extracted iris features, the corresponding polar coordinate equation is determined, and the RSA encryption algorithm is used to encrypt the first encrypted email to obtain the second encrypted email. The embodiments of the application introduce biometric information as the encryption and decryption key, which improves the security of encryption and provides users with a more convenient operation experience.

[0095] Please refer to Figure 5 In some embodiments, in step S402, the biometric feature extraction processing on the preprocessed image to obtain iris features includes the following steps:

[0096] Step S501, performing wavelet transformation processing on the preprocessed image according to a linear filter function to obtain encoded data;

[0097] Step S502, performing XOR operation processing on the encoded data to obtain the iris features.

[0098] In the embodiment of the present application, the linear filter function is used to perform wavelet transform on the preprocessed image, wherein the linear filter function is a Gabor function, and the expression of the function G(x, y) is as follows:

[0099] G(x, y) = exp(-(x^2 + p^2 * y^2) / (2 * o^2)) * cos(2 * pi * v * x);

[0100] wherein x and y are spatial coordinates, o is a scale parameter of the Gabor function, p is an ellipticity parameter, and v is a frequency parameter. The embodiment of the present application generates an output image by applying the Gabor function to each pixel point of the input image through wavelet transform, and extracts image features of different scales and directions by adjusting the parameters of the Gabor function. The wavelet transform is a new transform analysis method, which inherits and develops the idea of localization of short-time Fourier transform, and overcomes the shortcomings that the window size does not change with frequency, etc. The wavelet transform can provide a "time-frequency" window that changes with frequency, and is an ideal tool for time-frequency analysis and processing of signals. The main feature of the wavelet transform is that it can highlight the characteristics of some aspects of the problem through transformation, and can analyze the localization of time and frequency. Through scaling and translation operations, the signal is gradually refined in multiple scales, and finally the time is subdivided at high frequencies and the frequency is subdivided at low frequencies. The wavelet transform can automatically adapt to the requirements of time-frequency signal analysis, and can focus on any details of the signal. Specifically, the embodiment of the present application extracts the iris feature, can find important information in the iris for matching, can use 2-D Gabor transform to extract information of the normalized image, obtains the iris code through 2-D Gabor filter transform, and obtains the iris feature through XOR operation on the code. The embodiment of the present application extracts the iris feature, thereby encrypts the first encrypted email, thereby increases the difficulty of email cracking, and improves the security of the email content. This multi-encryption method can effectively resist various cracking attacks and reduce the risk of illegal acquisition of email content.

[0101] Please refer to Figure 6 In step S104 of some embodiments, the address comparison and identity verification processing of the second encrypted email according to the target electronic mailbox to obtain the first encrypted email includes the following steps:

[0102] Step S601: determining a recipient address according to the second encrypted email;

[0103] Step S602: performing data conversion and comparison processing on the address of the target electronic mailbox according to the recipient address to obtain an address comparison result;

[0104] Step S603: obtaining an eye image through the target electronic mailbox;

[0105] Step S604, according to the eye image, the second encrypted mail is processed by iris feature matching, and the identity verification result is obtained;

[0106] Step S605, according to the address comparison result and the identity verification result, the first encrypted mail is obtained.

[0107] In the embodiment of the application, when the second encrypted mail is sent, the recipient address, that is, the target IP address, is added to the second encrypted mail. The input position can be the outside of the mail, the title suffix, etc. The recipient address can be obtained by analyzing and identifying the second encrypted mail. Then, the address of the target electronic mailbox is processed by data conversion and comparison according to the recipient address. The target electronic mailbox is the mailbox that finally receives the second encrypted mail, and it is not necessarily the mailbox address that the sender wants to send to. Since the mail is transmitted through the mail server when it is sent from one electronic mailbox to another, these mail servers have their own IP addresses, and the transmission of the mail is routed through these IP addresses. The corresponding address can be obtained by querying the target electronic mailbox. By converting each part of the recipient address of the target electronic mailbox address into 32-bit numbers, the numerical values are compared according to the comparison formula. The expression of the comparison formula is:

[0108] P=A1-A2;

[0109] In the formula, P is the difference value after comparison, A1 is the first data value converted from the recipient address, and A2 is the second data value converted from the target electronic mailbox address. In the embodiment of the application, the two groups of data values are subtracted. If the value of P is 0, it means that the two groups of data are equal, and it is determined that the IP addresses are consistent. If the value of P is not 0, it means that the two groups of data are not equal, and it is determined that the IP addresses are inconsistent, so that the address comparison result is obtained. In the embodiment of the application, the eye image is obtained through the target electronic mailbox. After the mail is sent to the target electronic mailbox of the recipient, the image acquisition device such as a camera is automatically opened to collect the eye image of the recipient. According to the eye image, the second encrypted mail is processed by iris feature matching, and the identity verification result is obtained. Specifically, the eye of the recipient is photographed, and the photographed image is uploaded to the computer for storage. The image is preprocessed again, the data of the eye image is read, the inner and outer edges of the iris image are detected, the center coordinates and the short radius are extracted, the iris radius is obtained, the coordinate system is established, and the matching mode is matched and paired with the encrypted data set during sending. The matching and pairing method is compared by comparing the extracted iris feature data. The expression of the comparison formula is:

[0110] K=(B1-B2) / 100%;

[0111] In the formula, K is a difference value, B1 is an iris feature data value during encryption, B2 is an iris feature data value during decryption, and a result of identity verification is obtained by calculating whether there is a difference between the two sets of irises. If there is no difference, the received email is decrypted to obtain a first encrypted email, and the recipient reads the email information. The embodiment of the application introduces biological feature information as a key for encryption and decryption, so that the encryption method based on biological feature information has extremely high uniqueness and security. Because the biological feature information of each person, such as iris and fingerprint, is unique and comes from birth, this feature makes the biological feature information a key that cannot be copied or forged. The embodiment of the application uses biological feature information for encryption, which means that only the recipient with correct biological feature information can decrypt and read the email content. This encryption method based on biological feature information greatly improves the security of email communication and effectively prevents the risk of illegal acquisition or tampering of emails. Even if an unauthorized user intercepts an encrypted email, they cannot decrypt the email content because they cannot provide the correct biological feature information, thereby ensuring the security and privacy of the email information.

[0112] In step S605 of some embodiments, the first encrypted email is obtained according to the address comparison result and the identity verification result, including one of the following steps:

[0113] When the address comparison result or / and the identity verification result is not passed, the first encrypted email is automatically destroyed;

[0114] When the address comparison result and the identity verification result are passed, the first encrypted email is obtained.

[0115] In the embodiments of the present application, when either the address comparison result or the identity verification result is not passed, the first encrypted email is automatically destroyed. The automatic destruction of the email greatly enhances the security of the email transmission process. When the recipient attempts to access the encrypted email but the identity verification or address comparison fails, the system will immediately initiate the automatic email destruction mechanism. This mechanism works with extremely high efficiency, capable of completely destroying the email content in a very short time, ensuring that the email information cannot be accessed or misused by any unauthorized user. The process of automatic email destruction is not only fast, but also safe and reliable. The system automatically identifies identity verification failures and immediately executes the destruction command without human intervention. This not only reduces the security risks that may be caused by human operation, but also greatly improves the response speed and automation level of the entire system. The application of the automatic destruction mechanism significantly enhances the security defense capability of the system, effectively preventing information leakage and misuse by destroying emails that fail identity verification in a timely manner, providing more reliable protection for users. Whether in personal user communication or enterprise user file transmission, this mechanism plays an important role in ensuring the secure transmission and storage of information.
