A hybrid watermark that consists of a robust part and a fragile part \udcan be used to serve multiple purposes. The robust part can protect copyright \udinformation, the fragile part can detect tampering, and their combination enables identification of attacks encountered. This paper analyses an overlap and \uda non-overlap implementation of the robust and fragile parts in a hybrid system. \udThe difference between the two implementation methods lies in the robust and \udfragile watermarks embedding positions. Embedding capacity, computational \udcosts, watermark robustness, and tamper detection localization of the two implementations are analyzed. In addition, optimization issues of block size in the \udhybrid system are discussed
