佳能 SELPHY CP1500 隐私问题
2 分•作者: azca•9 个月前
今天扔掉一个打印墨盒时注意到，染料升华打印技术会在每张照片上留下每个颜色（蓝、黄、品红、白）的负片残余，而且细节足够丰富，如果有人花点时间通过 Photoshop 或 GIMP 自动化处理，将每个颜色的反相层叠并合并，就可以重建照片。在 Google 上搜索这个内容似乎没有找到任何相关结果，所以我想在这里发帖，看看我的推测是否正确，或者至少提醒大家注意这个问题。佳能发布了大量关于设备数字使用方面的隐私保护文档，但我想，这种老式的“信息提取”方式仍然是可能存在的。<p>佳能或相关行业的人士有什么见解吗？对于这些墨盒，消费者应该如何正确且保护隐私地进行处理？

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?
