Digital watermarking technology has been widely applied in the fields of multimedia copyright protection and broadcast monitoring,etc.For the purpose of broadcast monitoring,watermark information will first be embedded in the advertisement before it is sent to broadcast and television.In order to prevent possible fraud from any of the parties,it is essential to make two-factor authentication for video clips and watermark.A protocol based on two-factor authentication,specifying the generation and embedding of watermark are completed in the encryption domain,is proposed for broadcast monitoring.The method of using the homomorphic public key cryptography will be adopted.Moreover,the advertisement,the embedded watermark and the transaction are bound with embedding information as well.Based on this protocol,the most common problems such as the customer's right problem and non-binding problem can be solved.It can even help avoid fraud from advertiser and broadcast and television.
