In news related to the Panopticon Sort topic, scientists have developed an application for securing data from unwanted observers. While the Panopticon Sort provides opportunity for global and perpetual observation of subjects, quantum cryptography provides security from unwanted observation. In the original Panopticon theory, the expectation was that those being observed would change their behavior because they were being watched. Quantum cryptography provides that if there is unwanted observation (interception) the encryption code will change to prevent observation. Sorta like closing the window shade to keep from being observed.
European research has developed this secure encryption technology. The system is based on theories originated by Albert Einstein in his research on relativity. A by-product of that research opened up a whole new field of quantum physics. The quantum theory is based on the expectation that any observation in an experiment affects the outcome of the experiment.
Translation of encrypted data is dependent on translation keys. If those keys are transmitted electronically they might be intercepted without anyone else being aware of the breach. At the moment the only secure method to transmit keys for encrypted codes is by way of a courier (a person on a bike or other vehicle) with the code in a locked bag. Any interception of this transmission would be known.
Quantum methods of encryption get around this by sending encoded messages and translation code in pulses of light particles called photons. The photon has the property of changing if it is intercepted and/or observed. The change signals that the code has been intercepted and the data of the transmission altered by the interception.
Expected first application of this technology is still about seven years away and will probably find use in transmission of data to and from satellites. This will require the launch of new satellites.
Subsequent application may be to provide the highly desired security for your privacy on Face book or other open web sites.
Unquestionably, research has already started to find a way to overcome this immovable object (secure encryption of data) with an irresistible force (superpanopticon sort).

The quantum cryptography appears to be a short-term fix to the panopticon sort theory. While this encryption will protect individuals now from observation, the panopticon theorists will find a way to decode these transmissions.
There will always be a never-ending battle between those who observe network and internet transmissions and those who try to encrypt them. In this battle, the technology will become more expensive as time goes on as can be seen by the requirement of launching new satellites to aid in the quantum encryption.
It will soon have to be expected that information is always observed and consumers must always be aware.

Even though we believe that the quantum cryptography provides safe non-observable data interchange, it is only a matter of time until someone or something can observe it without any alterations. Technology in this sense can be compared to a disease inhealth care. A new disease comes out and its only a matter of time until doctors and scientists come out with a cure, but little do we know that a worst disease has been created around the corner..another limitation. as long as there is something that technology can prove that it can not be done, there will be people to prove others that it can in fact be done.
Oh, and facebook, will never be a secure site for everyone can observe it.
The topic of quantum cryptography is obvioulsy a new way of encrypting information so that anyone unauthorized to view the information can not. I agree with the other two posts, in that this may provide a temporary fix to the encryption process, but there will eventually be a way to break the code. It may be a while before somebody can, but it will eventually happen. Quantum cryptography is a very good idea for encrypting information in a manner in which if it the info. was to be intercepted that the code would change so the interceptor could not view the information. This will be a great stride for encrypting secure and private information in the future.
Does quantum cryptography require some sort of special equipment? Does the average person have the hardware or the processing power to do this out of their homes? We are wondering how much memory will it eat up in the computer if you send an email? It may not do much, but this seems like there are a lot of unknowns as of now. How far away is this from being used in our homes if it is seven years away from satellite use? From the blog posting it seems like this is a technology that will be available to consumers, but we are wondering how far out this is actually for the in home user. It seems like this code will eventually be broken even though it claims you may have highly desired privacy on open web sites such as FaceBook, but we do not see how FaceBook will ever have that type of security!
