Description

Technical Field

[0001] The present invention belongs to the technical field of physical-digital fusion storage, and specifically relates to an anti-intrusion data safe system deployed in the user's permanent living space. Through quantum optical storage media, biometric dynamic verification, and blockchain mapping technology, it realizes the local secure storage and trusted transfer of the core data of a trusted digital human. Background Art

[0002] With the rapid development of digital human technology, the problems of its data storage and security have become increasingly prominent. In the existing technology, the storage of digital human data mostly relies on traditional encryption algorithms and centralized cloud storage, and there are the following defects: 1) Insufficient key security: Traditional encryption algorithms (such as RSA) are threatened by quantum computing, and static keys are easily cracked; 2) Weak physical protection: Existing hardware storage devices lack anti-intrusion design and are difficult to resist physical attacks (such as violent disassembly or electromagnetic theft); 3) Low cross-domain synchronization efficiency: Although distributed storage schemes (such as erasure codes and secret sharing) can improve fault tolerance, the key management and data synchronization efficiency are relatively low, and they do not combine quantum security mechanisms; 4) Lack of dynamic data protection: Existing schemes do not consider the impact of biometric drift (such as iris changes caused by age growth) on identity anchoring, and long-term credibility is difficult to guarantee.

[0003] Existing patents and technological progress: Zhongji Security Technology proposed a secure storage system based on quantum secrecy, which improves the encryption efficiency through composite quantum keys, but does not solve the problems of physical protection and dynamic data calibration. The team of Guodun Quantum designed a quantum-secure fault-tolerant distributed cloud storage system, which combines Shamir secret sharing and erasure code technology, but relies on cloud servers and the local storage security is insufficient. Huawei developed a low-power quantum memory and optimized the heat dissipation design, but did not integrate a self-destruction mechanism and biometric dynamic verification.

[0004] This patent deeply integrates quantum optical storage, dynamic biometric anchoring, and physical self-destruction technology, and proposes a new method in the field of digital human data storage, filling the gaps in high-security local storage and cross-domain trusted synchronization in the existing technology. Summary of the Invention

[0005] The present invention proposes a trusted digital human local secure storage system, which includes an anti-intrusion safe, a quantum optical storage body, and a blockchain mapping engine. The safe adopts a five-layer composite protection structure (shape memory alloy + tungsten carbide armor), and triggers a three-level self-destruction (flame retardant / laser ablation / aluminum melt destruction) when an intrusion is detected ( Figure 1 ).

[0006] The key technical features of the present invention include a physical protection system, a data storage system, and a cross-domain synchronization mechanism.

[0007] The physical protection system uses an intrusion-resistant chassis with a five-layer composite structure: 1) The outer layer is a shape memory alloy (an alarm is triggered when the deformation > 3%); 2) An electromagnetic shielding layer (shielding effectiveness ≥ 80 dB); 3) A piezoelectric ceramic sensor array (sensitivity 0.1 g acceleration); 4) An optical camouflage layer (resistant to laser drilling); 5) The inner layer: tungsten carbide armor (compressive strength ≥ 6000 MPa).

[0008] The self-destruction mechanism adopts a three-level response: when a threat is detected by the system intrusion detection, a response is made according to the threat level. At level L1, a flame-retardant gas is released; at level L2, the storage surface is ablated by a laser; at level L3, the thermite is melted.

[0009] The data storage system is a quantum optical storage body: five-dimensional quartz glass storage is adopted (size 2.5 cm³, capacity 1 PB), the data is encoded as nano gratings (spacing 0.2 μm) generated by femtosecond laser inside the glass, and the reading method is confocal microscope decoding (non-contact, lifespan > 1000 years).

[0010] The hierarchical storage strategy is shown in Table 1: Table 1: Hierarchical storage strategy table Hierarchy Data Type Encryption Method Synchronization Policy L1 Biometric Benchmark Data National Cryptography SM9 Algorithm Never Export L2 Digital Human Behavior Model AES-256-GCM Daily Incremental Synchronization L3 Asset Transaction Voucher Post-Quantum NTRU Algorithm Real-Time Chain Up 。

[0011] The blockchain mapping protocol in the cross-domain synchronization mechanism is shown in Figure 3 the synchronization flowchart.

[0012] Disaster recovery method: when the local is damaged, the key shards are activated through biometrics (Shamir algorithm); the vouchers are extracted from the blockchain, and the data copy is released after being verified by the cloud. Description of the Drawings

[0016] Example 1: Protection of family digital heritage. Scenario: Storing family digital human memory data. Process: 1) The safe is placed in the family insurance room and automatically incrementally backed up to the family private chain at 23:00 every day; 2) The heir needs to verify simultaneously: palm vein feature (live detection), physical key (mechanical password wheel), voiceprint password (anti-recording attack algorithm); 3) When extracting data, it is optically transmitted to the designated terminal (to prevent electromagnetic leakage).

[0017] Example 2: Digital Twin Trusteeship for Enterprise Executives. Process: 1) The safe is deployed in the executive's office to store the decision-making behavior model; 2) After each strategic meeting: The AI butler automatically classifies and encrypts the data (L1-L3 levels), and the key decision-making data is uploaded to the blockchain in real time (delay < 200ms); 3) For authorization transfer, it is required that the executive's biometric authentication (heart rate variability detection) and quantum key verification by half of the board members.

[0018] Example 3: Medical Digital Human Data Archiving. Process: 1) The patient's digital human data is stored in the hospital safe cluster; 2) Data access rules: The attending doctor can read the L2 layer behavior model (differential privacy processing), and the research institution only obtains the aggregated analysis results (federated learning). When the patient's relatives inherit, a notary office needs to intervene (multi-signature smart contract).

[0019] Example 4: Storage of Government Sensitive Digital Humans. Process: 1) Use a distributed safe array (5 security zones); 2) Store data in shards (Raid 2.0 technology), and a single point cannot be restored; 3) Use a quantum key distribution (QKD) channel for cross-domain synchronization; 4) The self-destruction instruction requires triple biometric authentication (president + defense minister + supreme court).

[0020] Example 5: Mobile Digital Human Safe. Process: 1) The in-vehicle safe is equipped with a shock-absorbing platform (resistant to 30G impact); 2) In case of emergency: When violent disassembly is detected, the core data area is laser-ablated. When the GPS positioning is abnormal, the L1 layer biometric data is automatically erased; 3) Maintain a heartbeat connection with the blockchain through a satellite link.
