Chaos-based Yellow River dam dangerous case image encryption method

Abstract

The invention discloses a Yellow River dam bank dangerous case image encryption method based on chaos, and the method carries out the encryption of a Yellow River dam bank dangerous case image shot by a camera, transmits the image to a server through a public network, and carries out the decryption, thereby enabling the transmission of information from the public network to be safer. The method comprises the following steps that Arnold transformation is used for scrambling a dangerous case image, shot by a camera, of the Yellow River dam bank; initial values and control parameters of the Logistic chaotic system and the Chen hyperchaotic system are given, and iteration and quantitative sorting are carried out to obtain required chaotic sequences; performing specific rule operation on the scrambled image pixel value, and performing secondary scrambling on the operated pixel matrix to obtain an encrypted image; and transmitting the encrypted image to a server side through a network, and carrying out decryption operation to obtain an original Yellow River dam bank dangerous case image. According to the invention, the security of information transmission in the public network is greatly improved, and the problem of information leakage caused by hostile attack of information is avoided.

Description

technical field [0001] The invention belongs to the technical field of river basin dangerous situation monitoring, and in particular relates to a chaos-based method for encrypting dangerous situation images of Yellow River dam banks. Background technique [0002] River disasters have been one of the main disasters in my country since ancient times, and the dangers of the Yellow River occur frequently. When the flood season comes, accidents on the Yellow River always occur frequently. Mainly due to sediment precipitation and frequent rainfall, if the danger of the Yellow River can be detected early, the safety of life and property of the people on the banks of the Yellow River can be greatly guaranteed. [0003] The current danger detection technology of the Yellow River mainly includes satellite remote sensing technology, real-time camera monitoring technology and manual inspection. However, the cost of satellite remote sensing technology is too high, and the detection res...

Problems solved by technology

[0006] Aiming at the problem that the danger image of the Yellow River dam bank may be stolen when it is transmitted on the public network, which may cause the dam bank to be attacked and threaten the life and property safety of the people along the Yellow River, the present invention proposes a chaos-based Yellow River dam danger image Encryption method, chaos refers to the irregular movement in a deterministic system, with the slight change of the initial value, the iterated value of the chaotic system will change greatly, and the anti-attack ability is strong
