Abstract:

Verifiability and traceability are important challenges to the sharing and retention of electronic licenses.Traditional methods only ensure the verifiability of the issuer through electronic signature technology,but the verifiability of the holder and the depositor and the traceability of the license leakage are difficult to guarantee.Therefore,a verifiable and traceable electronic license sharing deposit scheme is proposed.First,aiming at the problem of unauthorized use of electronic licenses and the inability to trace after leakage,a model of the electronic license sharing and deposit system is constructed.Second,aiming at the problem of watermark information loss in the traditional strong robust watermarking algorithm,the existing strong robust watermarking algorithm is improved based on the BCH code,so as to realize the error correction of watermark information distortion.Finally,in order to realize the verifiability of the issuer,the holder and the depositor as well as the efficient traceability after the leakage of the electronic license,the verifiable and traceable electronic license model is constructed by combining the proposed robust watermark and reversible information hiding technology,on the basis of which the electronic license sharing and deposit protocol is designed to ensure the real authorized use of the license and the efficient traceability after the leakage.The analysis of security and efficiency shows that this scheme can achieve an efficient traceability after license leakage and has a good anti-collusion attack detection ability under the premise of ensuring the verifiability of the three parties,and that its execution time consumption is low enough to meet the needs of practical applications.

Key words: robust watermarking, reversible information hiding, electronic license, verifiable, traceable
