Modern cryptography technology has been developed for nearly a hundred years. Advanced, safe, and controllable cryptography technology is the foundation of network security. Today, China is vigorously developing the digital economy, and it has been entrusted with an important historical mission. Although blockchain technology has only emerged in recent years, as a "trust machine", it is an information security infrastructure in the digital age just like passwords. The organic combination of blockchain and encryption technology will greatly reduce the cost of establishing trust and greatly improve information security. Security protection capabilities.
Tongfudun has long been committed to the research and development of blockchain and cryptography technology . In recent years, it has been actively applying blockchain cryptography technology to practice. The developed blockchain cryptography can be used for data security storage, data encryption and sharing , etc. scenarios to protect data security.
A data security storage pain point
Cloud data storage is a mode of online online storage, that is, data is stored on multiple virtual servers usually hosted by a third party, rather than on a dedicated server. Those who need to store and host data can meet their data storage needs by purchasing or leasing storage space from the data center provided by the hosting company.
However, there are certain hidden dangers in the use of existing cloud storage technologies. For example, there are many confidential files or user privacy in the files uploaded by users to cloud storage through the platform. These data are mostly stored in plain text or in encrypted space. , even for encrypted space storage, its security only depends on the cloud platform itself. Once the platform data is invaded or tampered with, the privacy of users will be greatly leaked; in addition, the data on the cloud platform cannot really prove that the ownership of the data is Users also have a platform, that is, the platform itself has the risk of arbitrarily tampering with the user's data, which greatly threatens the security of the user's private data, such as identity information, ID photos, photos, identity documents, and communication records.
Two data encryption sharing pain points
At present, data sharing is usually just channel encryption, and the sender and receiver mostly encrypt and share end-to-end through the server in the form of plain text. During the sharing process, the data is usually visible in the server, so there is a serious risk of data leakage. At the same time, the data sharing record is saved and maintained by a third-party server, making the credibility of the sharing record completely dependent on the third-party server and cannot be traced back. If the third-party server is attacked and the data is tampered with or forged, it will directly lead to the untrustworthiness of the shared data.
Santong Fudun block chain password is effective
Recently, Tongfudun's blockchain technology-related patents have successfully authorized an invention patent named "A Data Encryption Sharing System and Method Based on Blockchain and Re-encryption" . It has further consolidated the technical fortress of Tongfudun block chain password and escorted data security.
#Encryption Storage#Encryption Sharing
In the " on-chain document " function of the Tongfudun " on-chain meeting " application , the use of blockchain and re-encrypted data encryption sharing system, combined with the interstellar file storage system (IPFS), realizes the data security storage and sharing function, data Autonomy belongs to the user, and the data sharing channel is safe and secret.
#Secret message
In the " Secret Letter " function of the Tongfudun " Chain Meeting " application , the blockchain password is adapted to various data types such as voice calls, video calls, texts, emoticons, voice messages, picture messages, and file messages, ensuring Security and confidentiality of " Secret " messages.
#Distributed digital identity
通付盾“链上会”应用的中的“数字身份”是基于区块链技术的分布式数字身份（DID）。在区块链密码的去中心化环境下，用户的公私钥体系取代传统互联网的账户体系。用户具有完全的自主性，私钥本地生成与管理，用户可使用DID进行自主身份证明和数据签名等应用功能。
数字化技术正带领我们来到了一个更广阔的数字经济时代，数字空间的安全是构建有序、稳定数字经济环境的重要基础，而安全最重要的核心是信任与隐私，信任成本的降低和数据隐私的安全将是加速社会进步的重大推动力，这就需要密码技术和区块链技术的发展与结合。
通付盾以分布式数字身份和大数据决策智能技术为核心，提出“云链一体”战略：通过“链上会”作为分布式数字身份载体使用数信云SaaS，通过“数信云”SaaS在“链上会”内构建轻应用，云链一体，云端协同。“云链一体”是通付盾成为Web3赋能者的战略路径。建设者们通过分布式技术与协议在数字空间创造出了全新的场景与应用。Web3是一个交叉领域，是区块链、大数据、人工智能、云计算、网络安全等最先进数字化技术的大集成。通过十余年的技术积累，通付盾已经形成了一套产品体系，针对两大Web3核心机遇提出了自主知识产权的Web3基础设施解决方案。通付盾是Web3引领者，Web2与Web3连接者。
