Description

Terminal and encryption and decryption method thereof Technical field

The embodiments of the present invention relate to the field of intelligent communications, and in particular, to a terminal and a method for encrypting and decrypting the same.

Background technique

With the transformation and development of the information age, more and more social networking sites, social instant messaging tools and server terminals need to establish and store user accounts and user chat data. Many website interactions also require users to perform password input verification and encryption and decryption operations. To prevent the infusion of malicious programs, data leakage and damage to protect privacy issues.

Currently, when a user logs in to various accounts or uses some chat tools to interact, the server still adopts a unified encryption means and a key in order to encrypt the user's chat content. In this way, it is easy to crack and view the encrypted content on the server side, or inject the Trojan to intercept the relevant input data in the terminal device.

For example, when a user logs in or submits an operation, or inputs a necessary information such as a bank card account or a password, the user often needs to input the keyboard mode of the application to submit the next operation. Sometimes, the letters or numbers of the input keyboard that comes with the application are even out of order, in order to prevent important private data from being captured by malicious programs.

Currently, the input of important user information is usually implemented in plain text or using the input key, or a simple digital or logical operation, allowing the user to fill in the encryption and decryption key or the arithmetic answer according to the text in the picture. . In the era of computers (PCs), the input mode of the devices is relatively simple, and the above methods take into account both efficiency and security, and are popularized. However, in the era of mobile device communication, the above methods are single, cumbersome and backward.

Moreover, with the increase of malicious programs, the use of background malicious programs to read text information from the user's input operations has gradually become a mature technology, and the reliability of traditional user input recognition is gradually lost. In order to overcome this situation, the visual input keyboard and the input logic sequence are often used to increase the difficulty of user input recognition. However, this method also causes difficulty for the user to operate. Once the user inputs the mistake, it is difficult to input the password successfully. The key is decrypted or encrypted. Moreover, with the increasingly unified terminal intelligent platform, the terminal technology is becoming more and more mature, and the traditional encryption and decryption using the keyboard is adopted. The approach is also facing increasing risks of cracking interception.

In addition, when the current user uses the mobile device, the screen may be too small, the resolution is insufficient, the network page layout and the like, and the cumbersome operation such as zooming in, adjusting the page, moving the cursor to the input box, etc., can be performed to read the encryption and decryption key input box. And input; at the same time in the page that automatically saves the user name and password, the user still has to manually input the encryption and decryption key, which causes a bottleneck of user experience improvement and efficiency improvement; part of the key input is complicated and monotonous, and brings the user The cumbersome operation and interference have greatly affected the user experience.

Preferred embodiment of the invention

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the absence of conflict, The features in the embodiments and the examples in the application can be arbitrarily combined with each other.

The invention will be described in detail below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1 , the encryption method provided by the preferred embodiment of the present invention includes the following steps: when the user performs data processing on the application interface, step 11: detecting the biometric feature of the user and acquiring biometric information of the user; Step 12: When the obtained biometric information satisfies the encryption condition of the data processing, the data is encrypted.

As shown in FIG. 2, the decryption method provided by the preferred embodiment of the present invention includes the following steps: when the user performs data processing on the application interface, step 21: detecting the biometrics of the user and acquiring biometric information of the user; When the obtained biometric information satisfies the decryption condition of the data processing, the data is decrypted.

In a preferred embodiment of the present invention, data processing performed by the user on the application interface is, for example, data input, data submission, or data transmission.

In a preferred embodiment of the present invention, the biometric features include one or a combination of the following: a sound having a recognition effect, a voiceprint, a pressure, a fingerprint, an action, and a gesture. The biometric feature having the recognition effect indicates that the terminal can detect the biometric signal through a related device (eg, a sensor, a sensor), and can obtain information data related to the biometric signal. For example, the motion sensor of the terminal can be used to detect and acquire information data such as acceleration and direction of the user motion.

As shown in FIG. 3 and FIG. 4, in the first preferred embodiment of the present invention, the terminal is, for example, a mobile terminal (a mobile phone or the like). Here, a chat application is taken as an example for description. The biometrics are, for example, a gesture of the user on the touch screen and an action of the user operating the terminal. As shown in Figure 3, it includes:

Step 001: The terminal determines whether to enter a scenario (for example, a chat scenario) that requires human recognition. If the user enters the plaintext to send the input item, the content is submitted in the normal way; if the user enters the ciphertext input item (that is, the item needs to be encrypted and sent by the user to send the session chat content, and the receiver also needs to take the agreed corresponding operation to view Corresponding to the content), the process proceeds to step S002.

Step 002: The terminal enables biometric signal detection for the user. For example, the input gesture trajectory of the user on the touch screen and the action of the user operating the terminal are monitored in real time, wherein the action of the user operating the terminal can be monitored, for example, by data (eg, acceleration) detected by the sensor of the terminal.

Step 003: The terminal determines whether the user needs to perform content input, send or submit operations. If the user is required to perform an information input operation in step 003, the process proceeds to step 004. If the user does not need to input, send or submit the content, the process proceeds to step 005.

Step 004: The terminal monitors the input operation of the user, and determines whether the acceleration detected by the sensor reaches a specified threshold. If the acceleration detected by the sensor reaches the specified threshold, the verification proceeds to step 007, otherwise, the process proceeds to step 006.

Step 005: Wait for the submitting action of the user to determine whether the submitting action satisfies the relevant threshold. When the terminal confirms that there is a sensing signal such as a user gesture track, an acceleration detected by the sensor, and the acquisition of the biometric information such as the gesture track and the acceleration detected by the sensor is synchronously related to the information input, the submitting operation is performed through the verification link (ie, Step 007), and performing encryption execution with the operation code. Otherwise, proceed to step 006.

Step 006: If the encryption verification fails, the terminal prompts to resubmit the operation, or submits by using a traditional encryption and decryption key or the like.

Step 007: If the encryption verification is passed, the submit operation is performed.

Taking the terminal application interface shown in FIG. 4 as an example, the user inputs the plaintext transmission content (region S101) on the touch screen of the terminal and clicks to send the chat content (region S102), and the receiving terminal can directly view the plaintext content, which is applicable to the general disclosure. Conversation. If the user inputs in the terminal to encrypt and send the chat content (area S103), such as cipher text, confidential privacy chat content, etc., the terminal initiates biometric detection, for example, monitoring whether there is a gesture trajectory, an acceleration detected by the sensor, and the like, and determining the detection. Whether the biometric signal is consistent with the required sensing signal (eg, as indicated by S104, ie, gesture input Z or right turn 45 degrees). When the biometric signal is detected, and the obtained biometric data of the gesture track, the acceleration of the sensor, and the like are synchronously related to the information input, the submitting operation is performed through the encryption verification link, that is, the encryption and execution are performed by using the biometric information, and the Encrypt the sent chat content for encryption and submission.

In a second embodiment of the invention, the biometric is for example user motion. The application interface displayed by the terminal (for example, the mobile device) is an interface to be verified, to be submitted, or an input item, and the terminal starts the listening mode (ie, starts monitoring the biometric signal of the user), for example, automatically monitoring the direction and acceleration of the user through the sensor. Or the user implements the touch action of the click submission, and the terminal determines whether to obtain the corresponding verification information (sports feature data), and determines the correlation between the obtained information and the submit operation. If it exists and is related, it is confirmed that the operation is completed by the user, and the information is automatically submitted through the encryption verification link to perform the next operation. If there is no motion feature such as acceleration and touch track detected by the motion sensor, it may be determined by the malicious program. , the submission fails, prompting the user to resubmit or otherwise re-verify the encrypted submission.

In the third embodiment of the present invention, in the interface of the user logging in to the terminal, the background automatically starts to detect the user's operation behavior on the touch screen, monitors the acceleration detected by the sensor, the gesture track, and the like, and obtains the user name, account, or password after the user inputs The information such as the acceleration and gesture track detected by the sensor, when the user inputs the necessary information, confirms that the user collects the corresponding motion operation information during the above action, and then automatically passes the verification and performs the submit operation.

In the fourth embodiment of the present invention, the difference between the fourth embodiment and the third embodiment is that the user uses the body feeling, the gesture, and the like instead of the touch mode input in the information input link, and simultaneously monitors whether the gravity sensor or the like matches the input content. If the match is correct, it will be automatically verified by encryption and the encryption submission operation will be performed. For example, the sending terminal encrypts the sent chat content by the above user action, and sends the chat content to the receiving terminal, and the receiving terminal needs to perform corresponding decryption according to the agreed manner, so as to view the related information content.

As shown in FIG. 5, a preferred embodiment of the present invention further provides a terminal, including a biometric acquisition module 10 and an encryption module 11, and a biometric acquisition module, configured to detect a user's biological activity when the user performs data processing on the application interface. Feature, and acquiring biometric information of the user; the encryption module is configured to encrypt the data when the acquired biometric information satisfies the encryption condition of the data processing.

In addition, in the preferred embodiment of the present invention, the terminal further includes a decryption module 12 configured to decrypt the data when the acquired biometric information satisfies the decryption condition of the data processing.

The specific operation process of the terminal provided by the preferred embodiment of the present invention is as described in the foregoing encryption and decryption methods, and thus is not described herein.
