A distributed key generation system and method, comprising multiple electronic devices and a server. Each electronic device sends a data fragment, and the server synthesizes the key based on these fragments. This approach ensures that keys are not pre-generated, reducing the risk of key leakage. Users can define custom fragments as the smallest units, such as a melody, an image, or a fingerprint, which serve as unique vault key components. The key is instantly synthesized at the moment of approval using a proprietary, irreversible algorithm. Since no key is stored within the system, the risk of hacking is eliminated.

With the advancement of technology, digital photos and text have become common tools for recording and preserving information. Ensuring the authenticity and integrity of digital data against tampering and forgery is increasingly important. This technology encrypts and verifies the "fingerprint" of the data. Before generating digital content, it detects whether functions that can alter or replace data or web page source code are enabled and requires a browser restart to prevent screen manipulation.

Electronic contract signing is primarily achieved through hash algorithms and public-key cryptography to encrypt and decrypt contracts. Traditional contract signing solutions store electronic contracts with centralized third-party institutions, posing a risk of unauthorized tampering. This patented system introduces an innovative online contract signing and verification method by comparing the original contract’s hash value to ensure its integrity. The signed contract’s hash value is then uploaded to the blockchain for permanent storage. Additional anti-counterfeiting measures, such as company stamps, handwritten signatures, or biometric verification, enhance security while eliminating the need for complex paper-based processes, achieving a fully digital, undeniable contract signing workflow.

To prevent fraudsters from altering email content to deceive users into revealing sensitive information or making unauthorized payments, this invention introduces a system that verifies the authenticity of emails using embedded media files. When an email is sent, a screenshot of the email content and its fingerprint are uploaded to the blockchain for preservation. Upon receiving the email, the system verifies the fingerprint against the original and highlights any discrepancies. This feature is particularly useful for financial transactions, such as invoice delivery and wire transfer instructions, and serves as a blockchain-based solution for email authenticity verification in corporate contracts and financial communications.
