Abstract:Aiming at the problem of limited downloading bandwidth missile infrared telemetry data and damage to the content of image in the receiving end, this paper proposes a scheme combining a reversible data hiding algorithm with infrared telemetry images, based on the symmetric encryption system and the difference histogram translation algorithm.. On the one hand, the various auxiliary information of missile infrared telemetry data can be embedded into the image; On the other hand, the infrared telemetry image can be encrypted to ensure the security of the image content during transmission. At the image receiving end, through the same encryption key and embedding scheme as the image sending end, the lossless recovery of the image and the reversible extraction of embedded information are performed. The experimental results show that for the infrared telemetry image with a bit depth of 16 and a size of 128×128, the image redundancy space can be used to embed about 15000 bits of binary data, and the reversible recovery of the telemetry image and embedded data is guaranteed.
