Description
Technical Field
[0001] This invention relates to the field of audio encryption and information security technology, and in particular to an audio encryption speaker and encryption method. Background Technology
[0002] In highly confidential settings such as political meetings and internal group meetings, information leaks can have serious consequences. During these meetings, there are always instances where people secretly record the conversations, leading to the leakage of confidential information. To prevent this, the speakers employ advanced encryption technology to ensure that only authorized devices can receive audio signals, effectively blocking unauthorized recording and ensuring meeting security.
[0003] Traditional anti-recording techniques typically employ single-audio interference or simple frequency band encryption, but these methods have the following problems:
[0004] Insufficient encryption strength: Single-band encryption is easily cracked and cannot cope with complex eavesdropping devices.
[0005] Limited interference effect: Traditional interference techniques may affect the normal use of licensed equipment and cannot dynamically adapt to environmental changes.
[0006] Inadequate authorization management: The lack of a strict verification mechanism for authorized devices makes them vulnerable to being impersonated by unauthorized devices.
[0007] Poor environmental adaptability: Unable to dynamically adjust encryption and interference strategies based on the type and number of devices in the meeting environment.
[0008] Therefore, we propose an audio encryption speaker and encryption method. Summary of the Invention
[0009] This invention is proposed to address the shortcomings of existing technologies by providing an audio encryption speaker and encryption method.
[0010] In order to achieve the above object, the present invention adopts the following technical solutions:
[0011] An audio encryption speaker includes a speaker body, characterized in that it further includes a multi-band dynamic encryption module, a biometric identification authorization module, a quantum encryption module, an intelligent voice recognition and filtering module, a multi-modal encrypted transmission module, and an adaptive audio encoding module. The multi-band dynamic encryption module is used to dynamically adjust the encryption frequency band and encryption logic according to the importance of the meeting content and environmental changes.
[0012] The biometric identification authorization module integrates fingerprint, iris, and voiceprint modules to ensure that only verified authorized devices can receive and decode audio signals.
[0013] The quantum encryption module uses quantum key distribution (QKD) to ensure the security of audio signal transmission;
[0014] The intelligent voice recognition and filtering module is used to identify sensitive information in the meeting in real time and to filter or encrypt the sensitive information.
[0015] The multimodal encrypted transmission module combines audio signals with optical and electromagnetic signals for transmission, increasing the difficulty for unauthorized devices to capture and analyze the signal.
[0016] The adaptive audio encoding module dynamically adjusts the audio encoding method and parameters according to the meeting content and environmental noise to ensure the clarity and security of audio transmission.
[0017] Preferably, the system also includes an environment-adaptive interference module, which dynamically adjusts the frequency and intensity of the interference signal according to the type and number of recording devices. The environment-adaptive interference module has a built-in intelligent identification system that monitors the type and number of recording devices in the environment in real time.
[0018] Preferably, the system also includes a blockchain technology recording and verification module, which uses blockchain technology to record the identity and permission information of the authorized device to ensure the legality and uniqueness of the authorized device.
[0019] Preferably, the system also includes a multi-level encryption and decryption module, which encrypts the audio signal in multiple levels, with each level using a different encryption algorithm and key.
[0020] Preferably, the system also includes an intelligent environment monitoring and early warning module, which monitors abnormal signals and devices in the conference environment in real time, provides early warnings, and takes corresponding measures.
[0021] An encryption method for an audio encryption speaker includes a multi-band dynamic encryption method, a quantum encryption method, a multi-layer encryption and decryption method, an adaptive audio coding method, and a multimodal encryption method.
[0022] The specific steps of the multi-band dynamic encryption method are as follows:
[0023] A1. Frequency Band Division: The audio signal is divided into multiple frequency bands, including ultra-low frequency (0-20Hz), low frequency (20-200Hz), mid frequency (200-2000Hz), high frequency (2000-20000Hz) and ultra-high frequency (>20000Hz). Each frequency band is assigned a different encryption key according to the preset encryption logic.
[0024] A2. Dynamic encryption logic: The encryption frequency band selection and encryption logic are dynamically adjusted according to the importance of the meeting content and the level of environmental noise. For example, in highly confidential meetings, the encryption strength of ultra-high frequency and ultra-low frequency is increased, while in ordinary meetings, medium frequency and high frequency encryption are mainly used.
[0025] A3. Interleaving Encryption: High-frequency and low-frequency signals are interleaved according to a dynamically generated encryption matrix to form a complex audio code. The encryption matrix is generated based on timestamps, environmental noise characteristics, and keywords from the meeting content.
[0026] Through the above technical solutions, the multi-band dynamic encryption method dynamically adjusts the encryption logic, increasing the difficulty of cracking. High-frequency and low-frequency signals are interleaved for encryption, ensuring that unauthorized devices cannot decipher it.
[0027] As a preferred embodiment, the specific steps of the quantum encryption method are as follows:
[0028] B1. Quantum Key Distribution (QKD): Establishing a quantum communication channel between the speaker and the authorized device, transmitting keys through quantum states to ensure absolute security of key distribution;
[0029] B2. Audio signal encryption: The audio signal is encrypted using a quantum key to generate quantum encrypted audio data. The encrypted audio data is then transmitted via traditional sound waves or light signals.
[0030] B3. Quantum Decryption: After receiving quantum-encrypted audio data, the authorized device uses a quantum key to decrypt it and restore the original audio signal.
[0031] Through the above technical solutions, the quantum encryption method and quantum key distribution technology are unbreakable, ensuring the absolute security of audio signal transmission, suitable for highly confidential occasions, and preventing any form of eavesdropping.
[0032] As a preferred embodiment, the specific steps of the multi-layer encryption and decryption method are as follows;
[0033] C1. Layer division: The audio signal is divided into multiple layers, such as: base layer (low frequency signal), content layer (intermediate frequency signal), and enhancement layer (high frequency signal). Each layer uses a different encryption algorithm and key.
[0034] C2. Encryption Algorithm: The base layer uses a symmetric encryption algorithm (such as AES-256), the content layer uses an asymmetric encryption algorithm (such as RSA), and the enhancement layer uses a hybrid encryption algorithm (such as AES+RSA).
[0035] C3, Layer Interweaving: Interweaving signals from multiple encryption levels according to a preset logic to form the final encrypted audio signal;
[0036] C4. Decryption process: After receiving the encrypted audio signal, the authorized device decrypts it layer by layer in hierarchical order to finally restore the original audio signal.
[0037] Through the above technical solutions, the multi-layer encryption and decryption methods increase the difficulty of cracking. Even if some layers are cracked, the overall audio signal remains secure. Different encryption algorithms are used for different layers to improve the system's resistance to attacks.
[0038] Preferably, the adaptive audio coding method has the following specific steps:
[0039] D1. Environmental Noise Analysis: The speaker has a built-in noise sensor that analyzes the characteristics of environmental noise in real time and adjusts the audio encoding parameters according to the noise characteristics to ensure clear audio signal transmission.
[0040] D2. Dynamic encoding adjustment: In low-noise environments, high-fidelity audio encoding is used to ensure clear sound quality; in high-noise environments, anti-interference encoding is used to enhance the noise resistance of audio signals.
[0041] D3. Combination of encryption and encoding: Encryption information is embedded in the audio encoding process to ensure that the encoded audio signal can only be decoded by authorized devices.
[0042] Through the above technical solutions, the adaptive audio coding method improves the clarity and reliability of audio transmission, and combines encryption and encoding to prevent unauthorized devices from capturing valid information.
[0043] Preferably, the specific steps of the multimodal encryption method are as follows:
[0044] E1. Signal type selection: Combine audio signals with optical signals and electromagnetic signals to form multimodal transmission signals, such as transmitting audio signals through sound waves and transmitting encryption keys through optical signals;
[0045] E2, Signal Interleaving Encryption: Interleaving signals of different modes according to preset logic to form complex encrypted signals, which prevents unauthorized devices from simultaneously capturing and decoding signals of multiple modes;
[0046] E3. Authorized device decoding: After receiving multimodal signals, the authorized device separates and decodes the signals of different modes according to preset logic to restore the original audio.
[0047] Through the above technical solutions, the multimodal encryption method increases the difficulty for illegal devices to capture and analyze multimodal transmissions, thereby improving the security and reliability of audio signal transmission.
[0048] In summary, this invention significantly improves the security of audio signals by setting up a multi-band dynamic encryption module, a quantum encryption module, and a multi-modal encrypted transmission module, and by utilizing multi-band dynamic encryption, quantum encryption, and multi-level encryption technologies.
[0049] This invention features intelligent interference capabilities, with an environment-adaptive interference module ensuring the effectiveness of the interference signal while minimizing interference to authorized devices.
[0050] This invention features strict authorization management: the biometric identification module and the blockchain technology recording and verification module ensure the legality and uniqueness of authorized devices.
[0051] This invention has strong environmental adaptability: the intelligent environmental monitoring and early warning module can dynamically adapt to complex environments and block potential recording behavior in advance.
[0052] This invention optimizes user experience: the adaptive audio encoding module ensures clear communication of meeting content while preventing information leakage. Attached Figure Description

[0054] Figure 2 This is a schematic diagram of the speaker encryption method module of the present invention. Detailed Implementation
[0055] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0057] The multi-band dynamic encryption module dynamically adjusts the encryption frequency band and encryption logic based on the importance of the meeting content and environmental changes. It employs a complex audio matrix interwoven with high-frequency and low-frequency signals to ensure that unauthorized devices cannot decipher the encryption.
[0058] After receiving the audio signal, the speaker divides the audio signal into high-frequency and low-frequency components according to the preset encryption logic. The high-frequency and low-frequency signals are interwoven according to the dynamically generated encryption matrix to form a complex audio code. The encrypted audio signal is played through the speaker, and only authorized devices can decode and restore the original audio.
[0059] The biometric authentication module integrates fingerprint, iris, and voiceprint sensors to ensure that only verified authorized devices can receive and decode audio signals.
[0060] Users register their fingerprints, iris scans, or voiceprints on the authorized device. Before playing the audio signal, the speaker verifies the biometric information of the authorized device. Once the verification is successful, the speaker transmits the encrypted audio signal to the authorized device.
[0061] The quantum encryption module uses quantum key distribution (QKD) to ensure the security of audio signal transmission. A quantum key distribution channel is established between the speaker and the authorized device, and the audio signal is transmitted through quantum encryption technology to ensure absolute security during the transmission process.
[0062] The intelligent voice recognition and filtering module is used to identify sensitive information in the meeting in real time and to filter or encrypt the sensitive information.

[0065] The environmental adaptive interference module dynamically adjusts the frequency and intensity of the interference signal based on the type and number of recording devices. Its built-in intelligent recognition system monitors the type and number of recording devices in the environment in real time, and dynamically adjusts the intensity and frequency of the interference signal based on the monitoring results to ensure maximum interference effect.
[0066] The speaker's built-in intelligent recognition system monitors recording devices in the environment in real time. Based on the monitoring results, the speaker dynamically adjusts the frequency and intensity of the interference signal. The interference signal only targets unauthorized devices and does not affect the normal use of authorized devices.
[0067] The blockchain technology recording and verification module uses blockchain technology to record the identity and authorization information of authorized devices, ensuring the legality and uniqueness of authorized devices.
[0068] The speaker connects to a blockchain network to record the identity and permission information of authorized devices. Before each audio transmission, the speaker verifies the legitimacy of the authorized device through the blockchain network.
[0069] The multi-level encryption and decryption module divides the audio signal into multiple levels for encryption, with each level using a different encryption algorithm and key.
[0070] The intelligent environment monitoring and early warning module monitors abnormal signals and equipment in the conference environment in real time, provides early warnings, and takes corresponding measures.
