Description

Technical Field

[0001] This invention relates to the field of data security transmission technology, and in particular to a data security transmission method and system. Background Technology

[0002] In the field of modern information technology, the security and integrity of data are crucial to business operations, and secure data transmission has become an important aspect of legal compliance. Against this backdrop, businesses must ensure the security of their data during transmission to defend against potential threats such as data breaches, tampering, and unauthorized access.

[0003] Currently, the main data security transmission technologies on the market include Virtual Private Networks (VPNs) and Secure Sockets Layer / Transport Layer Security (SSL / TLS). VPNs protect data transmission by establishing an encrypted tunnel, while SSL / TLS provides data encryption and authentication mechanisms at the application layer. These technologies provide necessary security to a certain extent, but their limitations are becoming increasingly apparent when dealing with large-scale data and complex network environments.

[0004] The limitations of existing technologies are mainly reflected in the following aspects:

[0005] Performance bottleneck: In high data traffic scenarios, traditional encryption technologies often encounter performance bottlenecks due to computation and processing requirements, resulting in slower data transmission speeds and impacting business efficiency.

[0006] Lack of flexibility: Existing encryption schemes typically use fixed algorithms and parameters, making it difficult to adapt to the dynamic security needs of different types of data, and lacking the ability to assess and respond to data sensitivity in real time.

[0007] Cross-network transmission risks: When transmitting data between different network environments, such as from an intranet to the Internet, existing technologies cannot provide continuous security guarantees, especially when facing complex network attacks.

[0008] Compliance challenges: As data protection regulations become increasingly stringent, existing technologies are inadequate in meeting new compliance requirements and struggle to adapt to the ever-changing legal and regulatory environment. Summary of the Invention

[0009] To address the aforementioned problems, this invention proposes a data security transmission method and system that can ensure the confidentiality, integrity, and availability of data in any network environment. Regarding the data security transmission problems mentioned in the background art, the purpose of this invention is to solve the following specific technical challenges:

[0010] Improving data transmission performance: In response to the performance bottlenecks encountered by existing technologies when processing large-scale data, this invention aims to provide a system that can efficiently process large amounts of data transmission, thereby improving the speed and efficiency of data transmission.

[0011] Enhancing the flexibility of data transmission encryption: Considering the limitations of existing encryption schemes in adapting to different data security needs, the purpose of this invention is to develop a system that can dynamically adjust the encryption strategy according to data sensitivity.

[0012] Enhancing the security of cross-network transmission: In order to overcome the security risks of existing technologies when transmitting data between different network environments, this invention aims to provide a transmission method that can ensure data security under various network conditions.

[0013] Enhancing data transmission compliance: Given the stringent nature of data protection regulations, this invention aims to create a data transmission system that can meet ever-evolving compliance requirements.

[0014] The technical solution adopted in this invention is as follows:

[0015] On one hand, the present invention proposes a data security transmission method, comprising:

[0016] Data identification and classification: Real-time analysis of data streams using pre-trained machine learning models to identify and classify the data's format, type, and sensitivity;

[0017] Dynamic data encryption: Based on the identified and classified data, the appropriate encryption algorithm is selected from the encryption algorithm library for dynamic encryption;

[0018] Data watermark embedding: Based on dynamically encrypted data, a digital watermark is embedded, including data source and integrity verification information;

[0020] Data transmission status monitoring: Monitor data transmission status in real time and record audit logs.

[0021] Furthermore, in the adaptive data transmission, the parameters of the transmission protocol are automatically adjusted according to real-time network conditions, including:

[0022] When high latency or high packet loss rate is detected in the network, the adaptive transmission protocol automatically reduces the transmission rate or adds transmission reliability mechanisms to ensure the stability and security of data transmission. When the network condition improves, the adaptive transmission protocol automatically adjusts the parameters again to optimize transmission efficiency.

[0023] Furthermore, in the adaptive data transmission, any unauthorized tampering will cause the embedded watermark to be destroyed; at the data receiving end, the integrity and origin of the data are confirmed by extracting and verifying the watermark; if the watermark verification is successful, it indicates that the data has not been tampered with during transmission, and the data is then decrypted and provided to authorized users.

[0024] Furthermore, in the adaptive data transmission, the parameters of the transmission protocol include data encryption strength and transmission rate.

[0025] Furthermore, in the data transmission status monitoring, the audit log content includes data type, transmission time, source address, and destination address.

[0026] On the other hand, the present invention proposes a data security transmission system, comprising:

[0031] The data transmission status monitoring module is configured to monitor the data transmission status in real time and record audit logs.

[0032] Furthermore, the data adaptive transmission module automatically adjusts the parameters of the transmission protocol according to real-time network conditions, including:

[0033] When high latency or high packet loss rate is detected in the network, the adaptive transmission protocol automatically reduces the transmission rate or adds transmission reliability mechanisms to ensure the stability and security of data transmission. When the network condition improves, the adaptive transmission protocol automatically adjusts the parameters again to optimize transmission efficiency.

[0034] Furthermore, in the data adaptive transmission module, any unauthorized tampering will cause the embedded watermark to be destroyed; at the data receiving end, the integrity and source of the data are confirmed by extracting and verifying the watermark; if the watermark verification is successful, it indicates that the data has not been tampered with during transmission, and the data is then decrypted and provided to authorized users.

[0045] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments are now described. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention; that is, the described embodiments are only a part of the embodiments of the invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] like Figure 1 As shown, this embodiment provides a data security transmission method, including:

[0048] Data identification and classification: Real-time analysis of data streams using pre-trained machine learning models to identify and classify the data's format, type, and sensitivity;

[0049] Dynamic data encryption: Based on the identified and classified data, the appropriate encryption algorithm is selected from the encryption algorithm library for dynamic encryption;

[0050] Data watermark embedding: Based on dynamically encrypted data, a digital watermark is embedded, including data source and integrity verification information;

[0051] Adaptive data transmission: Transmits watermarked data and automatically adjusts the parameters of the transmission protocol based on real-time network conditions;

[0052] Data transmission status monitoring: Monitor data transmission status in real time and record audit logs.

[0053] In the data identification and classification process, this embodiment uses advanced artificial intelligence technologies, such as convolutional neural networks (CNNs) or recurrent neural networks (RNNs), to perform real-time analysis of the data stream to identify the data's format, type, and sensitivity. Leveraging big data processing capabilities, a pre-trained machine learning model automatically classifies the data and assesses its sensitivity. The purpose of data identification and classification is to assign data to different security levels, providing accurate decision support for dynamic encryption. The design principles are based on data feature extraction and pattern recognition, ensuring high accuracy and real-time response capabilities in data classification.

[0054] During dynamic data encryption, based on the output of data identification and classification, the dynamic encryption engine automatically selects the most suitable encryption algorithm from the encryption algorithm library to adapt to the sensitivity of the data and the network environment. This dynamic encryption engine employs cryptographic principles combined with data security requirements to achieve dynamic data encryption processing. The goal of dynamic data encryption is to enhance data security during transmission to adapt to constantly evolving network threats.

[0055] During the data watermarking process, a unique data watermark is generated and embedded based on the dynamic encryption results of the data. This watermark is used to verify data integrity and trace the data's origin. Data watermarking technology provides an additional layer of security, enhancing data traceability and tamper resistance. This embodiment employs digital watermark embedding and extraction techniques to ensure the watermark's concealment and robustness.

[0056] Preferably, the data secure transmission method of this embodiment integrates key security technologies such as identity authentication, access control, and data leakage prevention, forming a comprehensive security and confidentiality management system. Its design is based on information security management and access control theories, aiming to provide comprehensive security protection during data transmission and prevent unauthorized access and data leakage.

[0057] During adaptive data transmission, a secure transmission protocol automatically adjusts encryption strength and transmission rate based on real-time network conditions. This secure transmission protocol is designed to meet data transmission needs under different network environments and optimizes data transmission performance. Its design principles are based on network communication theory and data transmission optimization techniques to adapt to network fluctuations and changes.

[0058] During data transmission status monitoring, the system monitors the data transmission status in real time and records detailed audit logs, including key information such as data type, transmission time, source address, and destination address. When abnormal behavior is detected, an alarm will be triggered immediately, and corresponding protective measures will be taken. The design is based on real-time monitoring technology and event response mechanisms to improve the speed and capability of responding to and handling security incidents.

[0059] Example 2

[0060] This embodiment is based on embodiment 1:

[0061] This embodiment provides a data security transmission method, including key steps such as data identification, classification, encryption, transmission, reception, decryption, monitoring, and auditing. Figure 2 As shown, the workflow of the adaptive data security transmission system is described in detail, clearly demonstrating the entire processing from data source to data reception and decryption. The specific details are as follows:

[0062] Data source: The starting point of the process, representing the data to be transmitted.

[0063] Data identification and classification: The system first identifies the type and content of the data and then classifies it.

[0064] Data sensitivity assessment algorithm: Based on the content and type of the data, assess the sensitivity level of the data (low, medium, high).

[0065] Choose a lightweight encryption algorithm: For low-sensitivity data, choose a lightweight encryption algorithm for encryption.

[0066] Choose a standard encryption algorithm: For moderately sensitive data, choose a standard encryption algorithm.

[0067] Choose a strong encryption algorithm: For highly sensitive data, choose a strong encryption algorithm.

[0068] Data encryption processing: The data is encrypted according to the selected encryption algorithm.

[0069] Adaptive transmission protocol: The adaptive transmission protocol adjusts transmission parameters according to the network environment to ensure secure data transmission.

[0070] Data reception and decryption: The data receiver uses the corresponding decryption algorithm to decrypt the data.

[0071] Watermark verification: Watermark verification is performed on the decrypted data to ensure the integrity and origin of the data.

[0072] Data Usage: Verified data is made available to end users.

[0073] Deny access and log audit: Data access requests that fail to pass verification will be denied and an audit log will be logged.

[0074] Monitoring and Auditing: The system monitors the data transmission status in real time and records detailed audit logs.

[0075] Generate audit logs: Record monitored events and operations in the audit logs.

[0076] Security incident detection: Detects security incidents during data transmission.

[0077] Response mechanism activated: Once a security incident is detected, the response mechanism is activated immediately.

[0078] Incident handling: Handling security incidents.

[0079] Incident Logging and Notification: Record the results of security incident handling and notify relevant personnel when necessary.

[0080] Example 3

[0081] This embodiment provides a data security transmission system, including:

[0082] The data identification and classification module is configured to perform real-time analysis of data streams using a pre-trained machine learning model, identifying the format, type, and sensitivity of the data and classifying it.

[0083] The data dynamic encryption module is configured to dynamically encrypt data by selecting the appropriate encryption algorithm from the encryption algorithm library based on the identified and classified data.

[0084] The data watermark embedding module is configured to embed a digital watermark, including data source and integrity verification information, into dynamically encrypted data.

[0085] The data adaptive transmission module is configured to transmit watermarked data and automatically adjust the parameters of the transmission protocol according to real-time network conditions.

[0086] The data transmission status monitoring module is configured to monitor the data transmission status in real time and record audit logs.

[0087] In this embodiment, the data security transmission system identifies and classifies incoming data in real time. Through a data sensitivity assessment algorithm, the system identifies the sensitivity category of data containing personally identifiable information. Based on this assessment result, the dynamic encryption engine automatically selects an encryption algorithm (e.g., AES-256) to encrypt the data, ensuring data security during transmission. The encrypted data is transmitted to the receiving end via an adaptive transmission protocol and decrypted at the receiving end for final use.

[0088] In the embedding and verification process of the data watermarking technology in this embodiment: Before data encryption, the data secure transmission system generates a unique watermark containing data source and integrity verification information and embeds it into the data. During data transmission, any unauthorized tampering will destroy the watermark. At the data receiving end, the data secure transmission system confirms the integrity and source of the data by extracting and verifying the watermark. If the watermark verification passes, it indicates that the data has not been tampered with during transmission, and the data is subsequently decrypted and provided to authorized users.

[0089] The data security transmission system in this embodiment can automatically adjust the parameters of the transmission protocol according to changes in network conditions. When the system detects poor network conditions, such as high latency or high packet loss rate, the adaptive transmission protocol automatically reduces the transmission rate or adds transmission reliability mechanisms to ensure the stability and security of data transmission. After the network conditions improve, the protocol automatically adjusts the parameters again to optimize transmission efficiency.

[0090] The data security transmission system in this embodiment can also monitor the data transmission status in real time and generate audit logs. The monitoring component tracks the transmission status of the data stream in real time and records all relevant information, including data type, transmission time, source address, and destination address. This information is recorded in detail in the audit log for easy post-event auditing and analysis. If the data security transmission system detects abnormal behavior or a security event, it will trigger a response mechanism and record detailed information about the event so that the security team can take swift action.
