佳能Selphy CP1500的隐私问题
今天在扔掉一个墨盒时注意到，所使用的染料升华技术在每张照片中留下了每种颜色（蓝色、黄色、品红色、白色）的负片，细节足以让人花一点时间通过 Photoshop 或 GIMP 自动化处理，层叠并合并每种颜色的反向图像。用谷歌搜索这个问题似乎没有找到相关的结果，所以我想在这里发帖，以便纠正我的假设，或者至少引起大家对这个问题的关注。佳能在数字设备的隐私使用方面发布了相当多的支持文档，但我想老式的数据外泄仍然是一个可能性。
请问佳能或相关行业的朋友们有什么见解？对于这些墨盒，什么是合适且保护隐私的消费者处理选项？

Noticed today while throwing out a cartridge that the dye sublimation used leaves the negatives in each color (blue, yellow, magenta, white) for each photo and the details are enough to reconstruct the pictures if someone spent a little time to automate via Photoshop or gimp to layer and merge the inverse of each color. Searching for this on Google didn't seem to produce any relevant results so I figured I'd post here to be corrected on my assumptions, or at least raise awareness that it's a concern. Canon publishes quite a bit of support docs around privacy for the digital usage side of devices, but I guess old school exfiltrarion is still a possibility.<p>Anyone at Canon or relevant industries have any insight? What's a proper and privacy friendly consumer disposal option for these cartridges?
