重生之宠妃攻略微盘:远距离获取钥匙模板

加州圣迭戈分校的计算机科学家开发出一种软件Sneakey，能通过数字图像复制数十米外的钥匙。
其中一个演示，他们使用了手机摄像头拍摄照片复制钥匙；另一个演示，他们从60米外借助望远镜复制咖啡桌上的钥匙。程序利用常见的2D对应匹配算法映射目标的2D平面，计算出剖切位置和切削深度。这项技术并不新也不复杂，只要有手机摄像头和软件人人都能当钥匙窃贼。科学家并未公布用Matlab开发的代码。

Reconsidering Physical Key Secrecy: Teleduplication via Optical Decoding

Our SNEAKEY system correctly decoded the keys shown in the above image that was taken from the rooftop of a four floor building. The inlay shows the image that was used for decoding while the background provides a context for the extreme distances that our system can operate from. In this case the image was taken from 195 feet. This demonstration shows that a motivated attacker can covertly steal a victim's keys without fear of detection. The SNEAKEY system provides a compelling example of how digital computing techniques can breach the security of even physical analog systems in the real-world.
Abstract
The access control provided by a physical lock is based on the assumption that the information content of the corresponding key is private --- that duplication should require either possession of the key or a priori knowledge of how it was cut. However, the ever-increasing capabilities and prevalence of digital imaging technologies present a fundamental challenge to this privacy assumption. Using modest imaging equipment and standard computer vision algorithms, we demonstrate the effectiveness of physical key teleduplication --- extracting a key's complete and precise bitting code at a distance viaoptical decoding and then cutting precise duplicates. We describe our prototype system, Sneakey, and evaluate its effectiveness, in both laboratory and real-world settings, using the most popular residential key types in the U.S.

The code for this project was developed in Matlab. If there is sufficient interest I may release it in the future.
