Can Your Printer Spy on You ?

ပရင္႔တာ တစ္ခုကေန ထုတ္လုိက္တဲ႔ ပရင္႔စာရြက္တစ္ရြက္ကေနျပီးေတာ႔ ပရင္႔ထုတ္တဲ႔ ရက္စြဲ၊အခ်ိန္ ပရင္႔တာအမ်ိဳးအစား ပရင္႔တာစက္နံပါတ္စဥ္ Serial Number ကို သိေအာင္လုပ္လို႔ရတယ္လို႔ဆိုပါတယ္။ ပရင္႔ထုတ္လိုက္တဲ႔ စာရြက္တစ္ရြက္တိုင္းမွာ ပရင္႔တာ ထုတ္လုပ္သူ ကုမၸဏီက ထည္႔သြင္းျမႈပ္ႏွံထားတဲ႔ စက္ပိုင္းဆိုင္ရာကုဒ္ေတြကို ျပန္ျပီး Track Back လုပ္လို႔ရႏိုင္ပါတယ္။ Encode လုပ္ထားတာကို Decode ျပန္လုပ္တာျဖစ္ပါတယ္။ ၀ယ္ယူထားတဲ႔ ပရင္႔တာဟာ ထုတ္လုပ္သူ ေရာင္းခ်သူဆီမွာ မိမိအမည္၊လိပ္စာနဲ႔ မွတ္ပံုတင္ထားျခင္း မရွိရင္ေတာင္မွ ၀ယ္ယူတဲ႔ေဒသက တဆင္႔ Track လုပ္လို႔ရပါတယ္တဲ႔။ အဓိကကေတာ႔ Forensic Case ေတြမွာ Information ရယူဖို႔ပဲ ျဖစ္ပါတယ္။
ဒါနဲ႔ပတ္သတ္ျပီး EFF ဆိုတဲ႔ Electronic Frontier Foundation က သုေတသနလုပ္ျပီး သက္ေသျပထားပါတယ္။ EFF ရဲ႔ Machine Identification Code Technology Project က ဒီလိုဆိုပါတယ္။
Explains the EFF, "Imagine that every time you printed a document, it automatically included a secret code that could be used to identify the printer - and potentially, the person who used it. Sounds like something from an episode of "Alias," right? Unfortunately, the scenario isn't fictional. In a purported effort to identify counterfeiters, the US government has succeeded in persuading some color laser printer manufacturers to encode each page with identifying information. That means that without your knowledge or consent, an act you assume is private could become public. A communication tool you're using in everyday life could become a tool for government surveillance. And what's worse, there are no laws to prevent abuse."

ပံုေတြနဲ႔ အတူေသခ်ာရွင္းျပထားတာကို ဒီကေနသြားၾကည္႔ႏိုင္ပါတယ္။
