Description

Technical Field

[0001] The present invention relates to the field of security protection technology, and in particular to an Internet data security protection method and system based on an intelligent algorithm. Background Art

[0002] In the current digital age, Internet data security protection has become a core issue in the field of technology. Especially in the field of e-commerce platforms, with the surge in transaction volume and user data, ensuring data security and privacy has become an urgent task. Traditional security protection methods often rely on rule settings and fixed protection strategies, but these methods have limited ability to respond to rapidly changing forms of network attacks and emerging threats. Traditional methods usually rely on manual settings and manual rule updates, and cannot identify unknown attack patterns or respond to complex attack chains in a timely manner. In addition, rule engines often have performance bottlenecks when processing massive amounts of data, resulting in delayed responses to attack information or even missed reports.

[0003] The defects of existing data security protection measures stem from their adherence to static rules and preset protection frameworks. This approach shows obvious lag in the face of complex network attacks. For example, in e-commerce platforms, once attackers use new attack methods or covert strategies, traditional systems are often unable to detect and respond effectively in a timely manner. This protection lag not only increases the risk of data leakage, but may also cause serious financial losses and damage to brand reputation, bringing immeasurable negative impacts to platform operations. The introduction of intelligent algorithms can effectively avoid these problems and significantly reduce the probability of security incidents through real-time risk assessment and dynamic defense strategies.

Secondly, the intrusion protection module enhances the platform's defense against network attacks through network traffic monitoring, abnormal request identification and attack defense response. The abnormal request identification unit can identify abnormal network request patterns such as frequent IP requests and abnormal access time periods through machine learning algorithms, timely discover potential intrusion behaviors, and initiate responses through automated rules. When the attack behavior is identified, the attack defense response unit quickly executes defense measures, such as IP blocking, traffic speed limiting, etc., to prevent the spread of attacks to the greatest extent and ensure the security of the platform. Example

[0112] For Internet data security protection methods based on intelligent algorithms, please refer to Figure 2 , specifically: including the following steps:

[0113] Step 1: Collect user behavior data in real time through log records, sensors and API interfaces, including login information, browsing history, transaction records and IP addresses. By monitoring users' real-time operation behaviors, analyze their interaction patterns on the platform, including browsing time, frequent operations and transaction amounts;

[0114] Step 2: Encrypt sensitive data, including user account information, payment passwords, and transaction records, using symmetric encryption AES or asymmetric encryption RSA, TLS / SSL protocol to ensure encryption during data transmission, combined with quantum encryption technology to provide a higher level of security during data transmission;

[0115] Step 3: Use machine learning models such as random forest, support vector machine (SVM) or deep learning models to analyze the user's transaction behavior and payment method, and calculate and obtain: user behavior security factor Yhxw, data transmission security factor Sjcs and risk protection response factor Fxfh, identify potential fraudulent behaviors, including stolen and false transactions, and conduct dynamic risk assessment based on the user's historical behavior, transaction amount, geographic location, and payment device data, and obtain an assessment plan after threshold comparison;

[0116] Step 4: When logging in and making transactions, we use a combination of multiple authentication methods, including SMS verification code, fingerprint recognition and dynamic passwords to authenticate users, and use intelligent algorithms to analyze the user's device ID, login IP and geographic location to dynamically monitor the security of login behavior;

[0117] Step 5: Through deep learning models, including convolutional neural networks (CNN) and long short-term memory networks (LSTM), we analyze network traffic and platform logs, detect abnormal access and malicious requests or DDOS attacks in real time, and automatically identify and block abnormal behaviors or attacks based on preset security rules;

[0118] Step 6: Monitor the platform's security incidents in real time, promptly provide feedback on abnormalities or attack information, and automatically respond to security threats by triggering preset emergency measures including restricting account logins, freezing funds, and encrypting transmissions.

[0119] In this embodiment, through the implementation of the above steps, the platform has achieved remarkable results in improving data security, user behavior monitoring and network protection. First, real-time data collection and encryption processing ensure the integrity and security of user behavior data, and protect sensitive data such as account information, payment passwords and transaction records through multi-layer encryption, avoiding the risk of data leakage. The combination of TLS / SSL protocol and quantum encryption technology further enhances the anti-attack capability during data transmission and provides a higher level of security for user transactions. Secondly, intelligent risk analysis and behavior monitoring realize in-depth analysis of user transaction behavior through machine learning models (such as random forests, SVM and deep learning models), timely identify potential fraud behaviors such as stolen and false transactions, and help the platform achieve dynamic risk assessment and accurate identification. Through multi-dimensional data input (such as historical behavior, transaction amount, geographic location, payment device), the system can more accurately analyze user behavior patterns, and conduct risk assessment based on threshold comparison, so as to make a timely security response.
