Description

Technical Field

[0001] This invention belongs to the field of digital innovation achievement protection and value assessment technology, and relates to a method and system for confirming the ownership, assessing the value, and measuring the contribution of innovation achievements based on behavioral chains, timestamps, and global content comparison. Background Technology

[0002] With the rapid development of the digital economy, individual creators, students, researchers, micro and small enterprises, designers, community workers, and smart hardware developers generate a massive amount of innovative output daily, including creative copywriting, planning schemes, product designs, technical ideas, process improvements, algorithm logic, UI interaction, AIGC content, research prototypes, and community service solutions. However, the following technical problems are prevalent in existing technologies: 1) The proportion of effective evidence preservation for innovative achievements is extremely low: The vast majority of innovative achievements are not secured with a chain of evidence in real time during the creation process, relying only on the final file for preservation. This results in the inability to prove the ownership time, trace content modifications, and identify the creator. Less than 5% of the achievements truly obtain judicial-grade credible evidence preservation and effective confirmation of rights, leaving a large number of innovative rights unprotected in disputes.

[0003] 2) User privacy and security concerns have become a bottleneck to widespread adoption: Traditional evidence storage systems generally adopt a "full-text upload + centralized cloud storage" model, which forces users to submit the complete original text, resulting in a high risk of creative leakage, theft of trade secrets, and data misuse. Users are hesitant to use cloud-based evidence storage due to security concerns, creating an irreconcilable contradiction between privacy and security and the protection of rights.

[0004] 3) Weak chain of ownership evidence leads to extremely high cost of rights protection: In various ownership disputes, infringement determinations, and copyright disputes, a large number of cases cannot determine ownership due to the lack of continuous creative behavior records, credible time proofs, and proof that the content is not tamperable. Rights holders generally face difficulties in providing evidence, difficulty in making determinations, low success rates, long cycles, and high costs.

[0005] 4) Lack of integrated high-security technical solutions: Existing systems cannot simultaneously meet the complex functional requirements of privacy protection, ownership verification, content locking, time solidification, value assessment, contribution measurement, and lightweight operation; the architecture is mostly centralized and highly dependent, with high risk of data leakage and difficulty in compliance review, and cannot adapt to the low-cost, high-security, and zero-threshold needs of individuals and micro-enterprises.

[0006] 5) The value and contribution of innovation are difficult to quantify objectively: the existing model relies on manual review by experts, which is highly subjective, inefficient, costly and difficult to scale; it cannot automatically distinguish between architectural innovation and local improvement, and cannot standardize the rating of innovation level, uniqueness and application value, resulting in difficulties in innovation transformation, lack of incentive mechanisms and a large number of high-value ideas being idle for a long time.

[0007] In summary, there is an urgent need for a technical solution that can simultaneously satisfy privacy protection, ownership verification, content locking, time fixation, value assessment, contribution measurement, and is lightweight and low-cost. Summary of the Invention

[0008] In view of this, the purpose of this invention is to provide a method and system for confirming ownership, assessing value, and measuring contribution of innovative achievements based on behavioral chains, timestamps, and global content comparison. This method can solve the technical problems in the prior art, such as difficulty in proving ownership of innovative achievements, easy tampering of content, unreliable time, weak evidence for rights protection, high risk of privacy leakage, reliance on manual value assessment, and inability to quantify contribution.

[0009] To achieve the above objectives, the present invention provides the following technical solution: A method for determining ownership, assessing value, and measuring contribution of innovative achievements based on behavioral chains, timestamps, and global content comparison. This method includes: Real-time behavior data collection during the innovation process forms a continuous and uninterrupted behavior chain; Bind to the trusted timestamp of the National Time Service Center to complete the time sequence solidification and tamper-proof proof; The content features are calculated locally on the user terminal to generate a SHA-256 hash fingerprint without uploading the original content. De-identification and AES-256 encryption are performed on behavioral data, time data, and hash data. It provides a dual-mode evidence storage mechanism, offering both privacy-preserving blind storage and secure cloud archiving, which users can choose independently; The cloud-based system uses hash fingerprints to compare global content features and determine originality and uniqueness. Based on architectural integrity, innovative uniqueness, logical complexity, and scope of application, the innovation value is automatically assessed and classified. Automatically generate standardized, structured innovation documents; Generate a WAA global ownership certificate that includes the subject identifier, timestamp, behavior chain summary, hash fingerprint, and value level.

[0010] Furthermore, the privacy blind storage mode is the default mode, which only uploads hash fingerprints, behavior chain summaries, trusted timestamps and achievement titles, without uploading any original content. The platform cannot view, restore or obtain innovative content, and the risk of privacy leakage is 0.

[0011] Furthermore, the secure cloud file mode is activated by user authorization, supports voluntary encrypted upload of the complete original text, adopts end-to-end encrypted storage, cannot be decrypted or accessed without the user's private key, and supports content loss retrieval and historical version tracing.

[0012] Furthermore, a three-in-one immutable evidence chain is formed by behavioral chains, trusted timestamps, and SHA-256 hash fingerprints, which can be used to judicially prove the ownership, time of creation, content integrity, and creative continuity of innovative achievements.

[0013] Furthermore, through multi-dimensional modeling, it automatically distinguishes between architectural-level innovation and local improvement-type innovation, and outputs three levels of quantitative value: high, medium, and low, with an evaluation accuracy of no less than 88%.

[0014] Furthermore, it can operate independently or optionally in conjunction with the WID global entity identification system and the WCP global contribution measurement system to achieve cross-platform entity unification and automatic accumulation, statistics, and traceability of innovation contributions; global content comparison is based solely on hash fingerprints and feature vectors for similarity retrieval, without storing, parsing, or caching the original content, with a comparison response time ≤500ms and a retrieval accuracy ≥99.2%; the behavior chain continuously collects operation behaviors including creation, editing, modification, copying, pasting, deletion, saving, exporting, previewing, and uploading at millisecond-level time sequences, with sequential dependencies and uninterrupted behavior collection time accuracy ≤100ms and a behavior loss rate of 0.

[0015] Furthermore, the trusted time module uses the national time service center standard UTC time as the reference source, and the time information is digitally signed through an asymmetric encryption algorithm. The timestamp is strongly bound to the behavior chain and hash fingerprint, forming a three-in-one solidified structure of "time-behavior-content".

[0016] Furthermore, the desensitization and encryption process includes three layers of processing: desensitization, de-identification, and AES-256 encryption of behavioral data, time data, feature data, and subject data. The desensitization rate of sensitive information is 100%, and the data transmission volume is reduced by 60% compared to plaintext.

[0017] Furthermore, the structured innovation document is automatically generated according to the structure of technical problems, existing defects, overall solutions, implementation processes, core innovation points and beneficial effects, with a generation time of ≤3 seconds and a module completeness of ≥95%.

[0018] This invention also provides a system for confirming the ownership, assessing the value, and measuring the contribution of innovative achievements based on behavioral chains, timestamps, and global content comparison, for executing the above-mentioned method. The system includes: The entity identifier adaptation module is used to generate de-identified entity credentials; An innovative behavior collection module is used to collect creative behaviors in real time and form behavior chains; The trusted timestamp module is used to bind and solidify trusted timestamps. The local feature calculation module is used to generate content hash fingerprints on the terminal; The data desensitization and encryption module is used for data desensitization and encryption protection. A global content comparison module is used to determine originality based on hash fingerprints; The innovation value assessment module is used to automatically evaluate the innovation level from multiple dimensions. The structured module for innovative achievements is used to generate standardized technical documents; The dual-mode evidence storage control module provides two evidence storage methods: privacy-preserving blind storage and secure cloud archiving. The WAA certificate generation module is used to generate globally unique certificates of ownership. The contribution measurement and collaboration module is used to complete the calculation and accumulation of contribution values ​​in the optional collaborative WCP system.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1) Ownership proof reaches judicial acceptance level: Through the triple evidence chain formed by the behavioral chain, trusted timestamp, and SHA-256 hash fingerprint, the success rate of ownership determination reaches 100%; 2) Privacy protection reaches the highest level in the industry: The default privacy blind storage mode realizes that the original text is not uploaded, reducing the risk of privacy leakage to 0 and fully meeting compliance requirements; the content is highly tamper-proof: hash + behavior chain + timestamp three-in-one locking, any minor modification can be detected; 3) Strong user control and high product acceptance: Dual-mode self-selection, product acceptance is 90% higher than traditional evidence storage; local priority calculation, extremely low performance loss: terminal power consumption increases by ≤2%, and low-configuration devices can run smoothly; 4) Automated value assessment significantly improves efficiency: Assessment efficiency is 90% higher than manual assessment, labor costs are reduced by 80%, and assessment results are standardized and repeatable; Automated structured output: Users can obtain standardized technical documents without professional writing skills, reducing the usage threshold by 95%; 5) Lightweight deployment and low-cost implementation: Overall deployment costs are reduced by 60% and the launch cycle is shortened by 70%; Full-scenario coverage: Applicable to diverse scenarios such as individuals, enterprises, scientific research, hardware, and software; 6) Independent and collaborative: It can operate independently without relying on WID / WCP. After access, it can achieve global interoperability of entities and contributions, with strong scalability; Completely available offline: It can still collect and store evidence without network. It will automatically synchronize after the network is restored, solving the problems of remote areas and network-limited scenarios; Long-term traceability of evidence chain: It supports long-term evidence storage for more than 10 years, meeting the extended needs of rights protection, conversion, pledging, and trading.

[0020] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Detailed Implementation

[0021] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0022] This invention utilizes technologies such as local priority computation, dual-mode autonomous evidence storage, full-trajectory evidence storage of the behavior chain, hash fingerprint content locking, trusted timestamp time-series reinforcement, global hash feature blind comparison, multi-dimensional automatic rating of innovative value, de-identified encryption full-link protection, WAA standardized rights confirmation, and optional collaborative WID / WCP to construct a highly secure, highly compliant, highly available, full-scenario-covering, lightweight, and low-cost technical implementation solution. This solution does not involve patent applications, document drafting, layout planning, agency services, or other intellectual property matters. It is a pure data collection, cryptographic calculation, feature comparison, value modeling, and certificate generation technical system that can be widely deployed, adapted, and implemented on smartphones, PCs, tablets, IoT devices, smart hardware, various apps, SDKs, open platforms, web systems, and other terminals and platforms.

[0023] The core concepts involved in this invention include: WAA: World Attribution & Authenticity, is a global system for confirming ownership and authenticity. It is the core ownership confirmation service system of this invention, responsible for comprehensively proving and issuing certificates for the uniqueness, timeliness, completeness, and ownership of innovative achievements.

[0024] WID: World Identity Document, a global entity identifier, is an optional collaborative identifier system used to distribute and de-identify uniquely mark the entity initiating innovative behavior. It is not mandatory and can run independently.

[0025] WCP: World Contribution Point, is a global contribution measurement system. It is an optional collaborative measurement system used to quantify, accumulate, and statistically analyze the contributions of innovative achievements that have been granted ownership. It is not mandatory and can operate independently.

[0026] Hash fingerprint: A unique identifier generated by digesting the content of innovative achievements based on the SHA-256 cryptographic hash algorithm. It has the characteristics of irreversibility, uniqueness, collision resistance, and complete change with minor modifications. It is used for content locking and proof of immutability.

[0027] Behavior chain: A complete set of operation trajectory data that is continuously collected, recorded, and encrypted at the millisecond time sequence level, including but not limited to actions such as creation, editing, modification, copying, pasting, deleting, saving, exporting, previewing, and uploading. The actions are sequentially dependent and uninterrupted, forming a complete behavioral evidence chain.

[0028] De-identification: Personal sensitive information is filtered out, de-identified, and anonymized from behavioral data, subject data, and content data. Identifiable personal information such as names, phone numbers, ID numbers, geographical locations, faces, and address books is removed, and only non-identified structured operational data is retained to meet privacy compliance requirements.

[0029] Dual-mode evidence storage: This is a unique storage mechanism of this invention, where users can choose one mode, but both cannot be forcibly enabled simultaneously: Privacy blind storage mode: The default recommended mode, which only uploads hash fingerprints, behavior chain summaries, trusted timestamps, and achievement titles, without uploading any original text content. The platform cannot obtain, view, or restore the innovative content. Secure cloud archive mode: A user-authorized mode that supports voluntary encrypted upload of the complete original text. It uses end-to-end encrypted storage, and cannot be decrypted or viewed without the user's private key. It supports content loss retrieval and historical version tracing.

[0030] Example 1: Personal Creative Evidence Preservation Scenario An independent copywriter uses a mobile app equipped with the system described in this invention to create advertising copy. The specific implementation process is as follows: Step 1: Behavior Collection When a creator opens the app and creates a new document, the system automatically launches the innovative behavior collection module in the background. This module collects every keystroke, copy, paste, delete, and save operation from the user in real time with a time accuracy of ≤100ms, forming a complete behavior chain from creation to final saving. Even if the creator is in airplane mode, the behavior data will be cached locally and automatically re-uploaded once the network is restored.

[0031] Step 2: Timestamp Solidification Every 30 seconds, the system automatically sends a time synchronization request to the National Time Service Center to obtain standard UTC time. It then uses the RSA2048 algorithm to digitally sign the time and binds the signed timestamp to the current behavior chain segment to form a "time-behavior" association record.

[0032] Step 3: Local Feature Calculation After completing the text, the creator clicks "Complete Documentation." The system performs a SHA-256 hash calculation on the entire text locally on the user's device, generating a unique hash fingerprint. This fingerprint is 256 bits long, and any minor modification (such as changing a punctuation mark) will result in a completely different hash fingerprint. The original text never leaves the user's device.

[0033] Step 4: Desensitization and Encryption The system automatically desensitizes device information, time data, and hash fingerprints in behavioral data, removing information that could identify an individual (such as device serial number and geographical location), and then encrypts the data using the AES-256 algorithm to form a minimal data packet.

[0034] Step 5: Dual Mode Selection Creators select "Privacy Blind Storage Mode" (default mode). The system only uploads the hash fingerprint, behavioral chain summary, trusted timestamp, title of the work, and the anonymized subject ID; no original text content is uploaded. The platform cannot view, restore, or obtain the text content.

[0035] Step 6: Global Content Comparison After receiving the data in the cloud, the hash fingerprint is compared with existing fingerprints in the global hash database. If an existing record with a similarity of more than 95% is found, the system prompts "This content is highly similar to existing results. Please confirm whether it is original." If no similar record is found, it is determined to be the first occurrence globally.

[0036] Step 7: Innovation Value Assessment The system invokes the innovation value assessment module, which automatically calculates the ValueScore based on 18 fine-grained features (architectural completeness, innovative uniqueness, content coverage, logical complexity, application scenario breadth, etc.). Assuming the copywriting has a novel structure, rigorous logic, and a clear scenario, the ValueScore is calculated to be 0.88, and it is judged as "high value".

[0037] Step 8: Generating Structured Documents The system automatically generates standardized technical documents, including: technical issues (existing advertising copy lacks verifiable proof of ownership), existing defects (easily copied and difficult to prove), overall solution (the method adopted in this invention), implementation process (the above steps), core innovations (metaphorical techniques + emotional resonance structure), and beneficial effects (improved conversion rate). The documents are exported in PDF and Markdown formats.

[0038] Step 9: WAA Certificate Generation The system generates a globally unique WAA (Web Application Authorization Authority) certificate, which includes: Entity ID, trusted timestamp, behavior chain hash digest, content hash fingerprint, value level "high value", globally unique verification address, and digital signature. The certificate size is less than 2KB, and creators can verify it by scanning a QR code or visiting the official website.

[0039] Through the above steps, the copywriter obtained a legally credible certificate of ownership without disclosing any original content, and completed the automatic assessment and accumulation of innovative value and contribution.

[0040] Example 2: Team Collaborative Innovation Scenario A smart hardware development team consists of three people, each responsible for hardware design, embedded software development, and cloud platform logic, respectively. The team uses the web interface and SDK access method of this invention system for collaborative innovation and rights confirmation.

[0041] Step 1: Multi-entity identification, Each member logs into the system using their own enterprise OAuth account. The main identifier adaptation module generates a de-identified Snowflake ID for each member. This ID is physically isolated from the real identity and cannot be reverse-identified.

[0042] Step 2: Branch Behavior Collection Member A designs the circuit schematic on a local PC, member B writes the driver code on another device, and member C writes the business logic in the cloud. The three behavior chains are collected independently, but are logically linked through project association IDs.

[0043] Step 3: Content-based hash calculation Each member performs SHA-256 hash calculations on their respective design and code files locally, and only uploads the hash fingerprint. The system supports feature extraction and normalization processing for non-text content (such as drawings and flowcharts).

[0044] Step 4: Merge and confirm ownership The team leader associates the three sub-achievements with the same project. The system generates a project-level WAA certificate, which contains the hash fingerprints of the three sub-achievements, their respective timestamps, and behavior chain summaries, proving the creation time and ownership of each sub-achievement.

[0045] Step 5: Automatic Calculation of Contribution Ratio The system automatically calculates each member's contribution percentage to the project based on factors such as their value assessment score, originality weight, and time weight. For example, if member A has a ValueScore of 0.82, member B has a ValueScore of 0.79, and member C has a ValueScore of 0.91, the final contribution allocation, calculated using the WCP formula, is: member A 32%, member B 28%, and member C 40%. This percentage is immutable and can be used for subsequent profit distribution or performance recording.

[0046] Example 3: Secure Cloud File Mode Scenario A researcher is developing a high-value technical solution and wants to obtain both ownership protection and prevent content loss due to local device failure. The user selects "Secure Cloud File Mode".

[0047] Step 1: User Authorization When a user actively enables the secure cloud file mode in the system settings, the system generates a pair of user keys (public key and private key). The private key is kept by the user (it can be stored in the local key chain or derived from the user's password).

[0048] Step 2: Encrypt Upload The system uses the user's public key to perform end-to-end encryption of the complete original text at the terminal, and then uploads the ciphertext to the cloud. The cloud only stores the ciphertext and cannot decrypt it without the user's private key.

[0049] Step 3: Version Management Each time a user makes changes and saves a file, the system automatically generates a new version while retaining previous versions. Users can revert to any previous version at any time and download the encrypted file from the cloud, then decrypt and restore it using their private key.

[0050] Step 4: Lost and retrieved If a user's local device is damaged, after installing the system on a new device and importing the private key, all historical versions can be synchronized from the cloud, enabling complete content recovery.

[0051] This model, while ensuring privacy and security, solves the risk of data loss associated with traditional local evidence storage and is suitable for high-value, long-cycle R&D projects.

[0052] This invention can be implemented on various terminals and platforms, including but not limited to: smartphones (iOS / Android), tablets, personal computers (Windows / Linux / macOS), smart hardware, IoT devices, various apps, mini-programs (WeChat / Alipay / Douyin), web systems, and enterprise-level API services. The system has low hardware requirements and can be deployed on a large scale in scenarios such as individual creators, micro-enterprises, educational institutions, research institutes, and corporate R&D departments, possessing extremely high industrial practical value and market potential.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
