An Active-Passive Security Protection Method for Remote Sensing Image

An active-passive security protection method for remote sensing image is proposed in the paper. High strength content encryption method is used to protect the security of remote sensing image in the process of storage and transmission. The encryption side only need to encrypt the image once, users can get different fingerprinting image by decrypting the image with different keys. If user leaks the decrypted image, they will be identified by embedded fingerprinting information. Considering the remote sensing image´s special requirements to embed fingerprinting, a way to control the strength of embedded fingerprinting is proposed to reduce the influence to the application of remote sensing image.
