Presentation of results
In order to protect the digital identity and privacy security of Internet users, Tongfu Dun has researched and developed blockchain and password technology products. At present, 29 blockchain invention patents have been authorized. As of October 2019, Tongfu Dun is the first enterprise in China to obtain the number of blockchain authorized patents in the field of blockchain. Participated in the formulation and release of the first cryptography group standard in China and the formulation of relevant standards of blockchain privacy protection specifications. The potential cases of top 20 leading enterprises in 2018 Hurun blockchain enterprise ranking and 2019 trusted blockchain summit show the promotion effect of Tongfu Dun's blockchain technology on the real economy and show the real effect of enterprises on the chain to help the real economy.
Blockchain privacy protection
Based on the data encryption technologies such as national secret series algorithm, proxy re encryption and secure multi-party computing, block chain is used to further improve the transparency and trust of encryption process and the security of key management. Combined with the different actual use scenarios of customers, provide customers with data encryption solutions, covering the safe storage, sharing and application of data in each scenario, so that the privacy data does not go out, the personal data does not land, and the key data is not visible.
Write the external information into the PROVE Chain to complete the data exchange between the blockchain and the real world. Determine the smart contract to respond to the uncertain external world, guarantee the way of data interaction between the smart contract and the external, and realize the development and application of the interface service of data interaction between the blockchain and the real world.
Hybrid consensus algorithm
Hybrid consensus algorithm development and application, using multiple consensus mechanisms in the underlying structure of the same blockchain public chain, combining weight with mathematical algorithm, taking into account speed, security and decentralized nature.
PROVE Chain takes PayEgis PROVE Chain password as its technical core, and provides three services for enterprise customers, namely, electronic license security deposit certificate, electronic signature and blockchain encryption. Customers can use the functions and services related to the certification chain by accessing the certification chain network and integrating the certification chain SDK.
①Electronic security certificate. The certification chain provides enterprises with electronic license security services, and ensures the data of electronic license can not be tampered and supervised. Certificate chain electronic certificate security certificate service provides two types of certificate schemes, covering key / value, picture, log and other data formats.
②Electronic signature. The certification chain provides electronic signature services for customers, connects with authoritative CA institutions, "authoritative Ca + blockchain", and ensures the security and legal benefits of individual and enterprise contract signing. The blockchain digital signature service provides CA management services such as Ca application, CA revocation, CA extension, CA query, as well as signature, signature verification and other functions.
③Blockchain encryption. The proof chain provides customers with data encryption schemes based on blockchain and national secret series algorithm. Based on national secret series algorithm, proxy re encryption, secure multi-party computing and other data encryption technologies, the blockchain is used to further improve the transparency and credibility of encryption process and the security of key management. Combined with the different actual use scenarios of customers, provide customers with data encryption solutions, covering the safe storage, sharing and application of data in each scenario, so that the privacy data does not go out, the personal data does not land, and the key data is not visible.
With the certification chain as the underlying architecture, Tong Fu Dun DAPP provides enterprises and individual users with cloud identity authentication, encrypted communication, online signing, P2P payments with points，encrypted cloud disk and other functional services, to protect your business secrets. Tong Fu Dun DAPP provides services in the form of app. Users can search "PayEgis" in the app store or major Android application markets, and then install and use it.
①Cloud identity authentication. DApp of PayEgis provides a variety of cloud identity authentication functions, including "scan code login" and "token login", which are simple to integrate and meet your various cloud identity authentication needs.
②Encrypted communication(MiChat). Encrypt IM, easily transfer text, picture, voice, expression and other content, and call voice and video at will.
③Sign up online(eSign).The online signing function based on certification chain digital signature technology meets the needs of online signing between individuals, individuals, enterprises and enterprises in the daily life of users.
④P2P payments with points. DAPP includes the blockchain points based on the ProveChain, which can be used to exchange for encrypted cloud disk (MiYun) or other security services of Tong Fu Dun cloud service.
