| Summary: | The technology of digital watermarking and information hidden of image cannot solve the security problem of
confidential regional data, and thus the research of the high-performance encryption technology of confidential data
of Large Quantity of image has a important theoretical value and practical significance.In this paper, on the basis of
the characteristics of Large Quantity of Image and application requirements on security, a scheme of authorizing
the use of image based on multi-level secrurity is put forward. We propose multi-region and multi-level confidential
information of image encryption algorithm based on content. The same 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 the high confidentiality and high computing efficiency encryption algorithm and solve the difficult
problems of Large Quantity of Image on security and secrecy. |
