Error-tolerant searchable data sharing scheme

A new data sharing scheme was proposed to solve the problem of error-tolerant search and fine-grained access control.This new scheme adopted the technology of locality-sensitive hashing and the predicate encryption,which allowed users to search for Keywords in an error-tolerant manner,and modified the user's access rights easily by updating the encrypted data.The computational complexity of updating is more optimized than the existing scheme.The theoretical analysis shows that the proposed solution is correct,safe and effective.
