Due to the Corona-19 pandemic phenomenon, various video service platforms that provide OTT (Over The Top) services such as 'Netflix' have achieved rapid growth.OTT platforms that provide such video content do not disclose the viewing time of the content watched by users due to various issues such as personal information protection, so stakeholders are conducting third-party research on usage patterns.While an objective and reliable third-party method of investigating usage patterns is needed, efforts to protect personal information are also needed in the process.The information required for viewership surveys to investigate usage patterns only requires information about what content is used and to what extent, and does not require personal information about users.In this paper, we propose a method to generate and verify the generated usage information by de-identification using zero-knowledge proof protocol when a user selects a specific OTT platform and uses content through an OTT player agent that provides OTT services.
Abstract Facing the information era of rapid development of the Internet, university watercolor education is in urgent need of finding a new development direction. Through the emerging education model of Internet+education, this paper regards knowledge sharing as the transaction behavior of buyers and sellers in the knowledge market and establishes a smart contract model based on the knowledge supply and demand functions. A blockchain knowledge-sharing-based watercolor painting classroom model is proposed to break the traditional teaching role and apply it to the teaching and practical analysis of watercolor painting in universities. With the Internet+ education model, the teaching diversity increased by 26.90%, and the teaching interactivity increased by 6.12% compared with the original. Nearly 60% of the students thought that the teaching effect of the Internet+ education mode was improved. In the teaching practice, the students’ watercolor painting works received 7.53% more A grades in color usage compared to the original. For the evaluation of spatial level, the students who received A grades increased by 18.76% compared to the original. The Internet+ education model provides a new path for the development of university watercolor painting education, which helps cultivate watercolor painting artistic talents with both inclusive artistic thoughts and unique personal artistic characteristics.

Blockchain technology is a distributed database with features such as no forgery, full traceability, openness, and transparency which is superior in establishing trust mechanisms and brings new opportunities for finance, healthcare, technology, and education. As a required course of all universities in China, College English has a large demographic covering millions of students. But the traditional EFL summative assessment model fails to fully reflect the L2 learner’s learning process and increment performance. The current paper focuses on the novel applications of blockchain in the educational domain and how blockchain technology reshapes the EFL Formative Assessment framework in the consensus mechanism to achieve a decentralized and highly trusted learning process record and evaluation. This innovative approach aims at improving the openness, transparency, and fairness of the EFL learning process by recording and monitoring the teachers’ and students’ behaviors. The research findings of this paper provide preliminary exploration for L2 evaluation and supply some inspiration to policymakers, EFL practitioners, and technology developers about the potential usages of digital credentials anchored on blockchains.

More and more shared products and services have been introduced to the market one after another, which has changed the traditional Chinese economic model. The construction of digital teaching resources is one of the important contents of higher education informatization. Today, with the extremely developed network, the problem of sharing digital teaching resources in colleges and universities becomes more and more prominent. Network can not only realize the sharing of educational resources, but also greatly expand the information exchange between teachers and students, and create a learning environment for individual teaching for learners. With the continuous improvement of technology and the maturity of application, the Blockchain and new energy and related applications will develop rapidly under the impetus of the government and the huge social demand. As a new force to change the Internet, Blockchain and new energy will bring great changes to information resource sharing activities and information service institutions. This paper explores the application of Blockchain and new energy technology in the co construction and sharing mode of digital teaching resources in Colleges and universities through the research on the participation subjects of block chain technology and digital teaching resources co construction and sharing.
In traditional blockchain transactions,privacy protection is to encrypt users' sensitive information under the anonymity mechanism,and a trusted third party is involved to verify the transaction plaintext information.However,once the third party is attacked,the users' transaction information will be divulged.Furthermore,there is no truly trusted third party in a rational state.To better solve the privacy problems in blockchain transactions,and in view of issues of confidentiality verification of the tra-ders' transaction amount under the non-anonymous state,the PVC digital commitment protocol is adopted to hide the transaction amount in the commitment,and a publicly verifiable zero-knowledge proof scheme is established,so that verifiers are able to confidentially verify the legitimacy of the transaction without obtaining sensitive information from the traders.At the same time,the elliptic curve homomorphic encryption feature is used to encrypt the amount,thereby solving the problem of updating the traders' ciphertext ledger.The correctness of the proposed privacy protection scheme is verified and analyzed,and the results shows that compared with the existing schemes,the proposed scheme has the advantages of relatively low computational complexity,strong security and high efficiency.
Based on the cloud platform, the concept and importance of double-precision teaching in wisdom teaching is analyzed, and the basic framework of online and offline wisdom teaching based on blockchain technology is constructed in this paper. Based on the characteristics of blockchain such as security and decentralization, an accurate learning resource teaching model based on knowledge representation of learners and teaching resources is proposed. A double-precision collaborative strategy of accurate perception of wisdom teaching demand and accurate supply of resources is proposed. The framework of wisdom teaching is constructed, in which the accurate perception of wisdom teaching demand and the accurate supply of resources based on big data technology is analyzed. Based on blockchain technology, tracking the learning records of learners at each stage of learning is helpful. It effectively promotes the distribution and sharing of learning resources, efficiently bridges teaching resources and learning requirements, and provides more accurate, personalized learning support, and services for learners. It provides a secure data access strategy for both teachers and learners. The precise wisdom teaching framework based on blockchain technology has far-reaching practical value for the efficient development of online and offline teaching.
