At Present, the Existing Encryption Methods and Access Control Cannot Meet the Information Security Requirements of Medical Data, While Digital Watermarking Technology Can Effectively Avoid the Disadvantages of Traditional Cryptography Technology. in the Early Days When Digital Watermarking Technology Was Proposed, It Was Mainly Used for Copyright Protection and Authenticity Identification of Digital Products. in the Medical Field, We Not Only Hope to Effectively Hide the Watermark Information, But Also Hope That the Watermark Can Resist Various Attacks on the Network and Have Good Robustness, Which Will Not Affect the Medical Data Carrier Itself, and the Human Eye Cannot Perceive the Existence of the Watermark and Obtain Its Content. Based on the Practical Application, We Also Hope That the Watermark Embedding Capacity Can Meet the Actual Needs. to Solve These Problems, a Robust Watermarking Algorithm Based on Neural Network and Chaotic Mapping is Proposed.
