Content-Oriented Multi-level Security Authorization of Remote Sensing Images

  • The most confidential information of remote sensing images is related to military security and political stability, and confidential information of the regional data need to beencrypted to protect itself. On the basis of analyzing the characteristics of large quantity of remote sensing data and application requirements on security, a scheme of authorizing the use of remote sensing images based on multi-level secrurity is put forward. The same remote sensing images after encryption are distrtbuted to different level users, such as authorized user, partly authorized user, unauthorized user, but different authorization users acquire different importmant degree information after decryption through their own decryption keys. The scheme has high confidentiality and high computing efficiency encryption algorithm, and solve the difficult problems of large quantity of remote sensing data on security and secrecy.
