Indoor dynamic environment lo calization algorithm based on transfer learning
Published 2018-08-01“…The accuracy of the traditional indoor fingerprint lo calization system is limited bymany factors,such as the density of the reference location node in the fingerprint database and the characteristics of the indoor environment.When the indoor environment changes dynami cally,the RSS fluctuates,and usually does notmeet the assumption of the same distribution.Therefore,it was difficult to obtain high-precision requirements for conventional fingerprint positioningmethod.Aiming at the problem that the traditional algorithm couldn’t locate accurately,an algorithm based on the indoor fingerprint database was designed and implemented.The algorithm adopted the idea ofmigration learning to embed different data sets into the latent feature space,and the adverse effects of environmental changes on the system weremitigated.The simulation results show that the average positioning error of this algorithm is 1.23m.…”

Block cipher mode research based on identifier of text files
Published 2017-03-01“…The electronic code book(ECB)mode cannot conceal the data model of the plaintext and has only one private key to the whole plaintext.A block cipher mode based on identity for text files was proposed,which ab-sorbed the advantages of block cipher mode and the feature of plaintext string.A double Hash mapping structure was designed and one layer of the mapping structure maps the plaintext into discontinuous groups,another one which was based on the concept of identify library produced corresponding private key to the plaintext group.The model overcame the discontinuous group and single private key problem and effectively improved the security of the cipher text.The experiment results show that the new model has better security,flexibility and extensibility.…”

Blockchain-based service publishing scheme with recommendation for cold start users
Published 2021-01-01“…In order to solve the problem that the existing publishing systems were vulnerable to tampering, and it was difficult to recommend service information to “cold start” users, a blockchain-based service publishing scheme that supported cold-start user recommendations was proposed.The latent feature mapping model of a single auxiliary domain was extended to two auxiliary domains to make more accurate recommendations for cold start users in the target domain.In addition, the microservice architecture and block technology were combined to ensure system scalability, reliability and security.The experimental results of three real data sets extracted from Amazon transaction data show that the proposed recommendation model is better than most other recommendation methods, and the service release information can be safely stored in the blockchain to ensure that it is not changed.…”
