摘要
En 中文
Hashing for localization (HfL) is an effective method for fast localizing specific scenes in a large-scale remote sensing image. Key to its efficiency arises from a comprehensive deep hashing network that generates representational binary hash codes for image patches cropped from the remote sensing image. On the other hand, this article will investigate the problem of encrypting the remote sensing image against the HfL task. We refer to the new task as encrypting hashing against localization (EHaL). We characterize the EHaL task in term of two cues: 1) an encrypted image patch is supposed to appear as visually similar to its original image patch as possible and 2) the hash code generated by the deep hashing network for the encrypted image patch is supposed to be not close to its original class but close to a different class. Following the two cues, we develop an encrypted patch generator, which is trained in an adversarial fashion. Based on the encrypted patch generator, we propose two remote sensing image encryption frameworks that can cause nonlocalization and mislocalization to the HfL task separately. Experiments validates the effectiveness of our method. Reproducible executions are given at https://github.com/JingpengHan/EHaL.
