| description | The invention discloses an unmanned aerial vehicle remote sensing image protection method based on palmprint verification two-dimensional chaotic mapping, which adopts new two-dimensional chaotic mapping, and has the advantages that the new two-dimensional chaotic mapping is sufficiently sensitive to a key, is difficult to crack, can generate sufficiently random sequences and the like. An adopted stepped scanning algorithm is divided into three parts, the first part corresponds to the left lower part of a plaintext unmanned aerial vehicle remote sensing image, the second part corresponds to the diagonal part of the plaintext unmanned aerial vehicle remote sensing image, the third part corresponds to the right upper part of the plaintext unmanned aerial vehicle remote sensing image, and the first part and the third part both penetrate through the boundary. And the periodicity is extremely weak. A scanning route is in a step shape, the scanning route is complex, and the scanning scrambling effect is very good. |
