Description

Built-in Cam Memory Card Module The present invention relates to a built-in cam, and more specifically, to a memory card module of a built-in cam used in automobiles, etc. Unless otherwise indicated in this specification, the contents described in this identification item are not prior art for the claims of this application, and are not recognized as prior art simply because they are described in this identification item. Security issues regarding dashcams and built-in cameras currently installed in vehicles are emerging as a critical concern. In particular, since SD cards storing dashcam recording data are designed to be easily accessible to anyone, there is a risk that important evidence could be maliciously deleted or stolen in the event of an accident. Existing SD card modules are detachable via a standard push mechanism and are mounted in locations such as the glove box or center console, making them vulnerable to security breaches. Generally, dashcams automatically save recorded video in the event of an accident, but if the SD card is physically removed or damaged, the recorded evidence is lost. In conventional technology, methods utilizing SD card encryption and network transmission have been studied to solve this problem; however, due to the insufficient protection features of the SD card itself, physical removal and video leakage have not been completely prevented. For example, Korean Patent Publication No. 10-2011-0040556 presents a device and method for preventing tampering and forgery of black box data, and applies a technology to verify the integrity of recorded video data. While this technology is effective in ensuring that the video stored in the black box has not been tampered with, it has a limitation in that data protection is impossible if the SD card itself is physically removed.
