Mitigation of the Replay Attacks in a data sharing system using WSQ

I was wondering if one were interested in writing an algorithm for the demodulation of the Replay Attacks using the Wavelet Scalar Quantization merging the Huffman Decoder-Encoder as the designing sequence, what would be the possibility of mitigating the False Acceptance Rate (FAR) and the False Rejection Rate (FRR)?

Thank You.

The above listed problem should be of interest to serious programmers. Feds want to work on the ramification of the same and you can guess the utilities of the application in frequency subbands allotment to any generic variables. I am based at MIT and keenly working on it with some like minded approach. If anyone is interested please drop a line.

This is in response to Jyoti Ballabh's challenge on the Velocity Reviews. I kind of have a vague idea of what you are trying to obtain through the whole Huffman encryption. I came up with a python algorithm for the problem. But there is a slight zonal overlap between the FAR and the FRR. I didn't want to post the solution as a reply on the thread due to the very nature of it. Your profile on the velocity ratio doesn't answer where it could be mailed as you have not written anything. I would be on your campus on Friday for the Mathematics Colloqium in building 2 and if you are in town you could come over and we could talk about it.

Replay attacks using RFID sequencing is a classical trouble.

I will give you the vague guidelines-

The filing of the biometrics could be extrapolated for a 512 frequency subbands fractionation and this could be achieved by the usage of the Floating Variables, implying using string variables within string variables. The utility of floating variables in zeta-penta-exa-avogadro flops (10^12, 10^15, 10^18.......10^23 files operating per second) is well known and its application can not supersede its use in the Biometric profiling. The merits of this application would be- the entire Database is faster to scan, avoids jamming, non-repudiation, non-hackable, non-alterable (even if one were to hack into the system and try to gain access to the Database, one wouldn't know what to look for as hacking entails only the fixed point variables, it's virtually impossible to come up with an algorithm for floating ones).

As regards the image based challenge/ response in which the sensor is assumed to be intelligent, we introduce a processor or a chip which can perform calculations. In reference to the cryptographic techniques which are computationally intensive and need to maintain many secret keys for the different sensors. Digital signature authenticity can only guarantee the integrity not the liveliness. In the image-based challenge response there is certainty that the image was acquired only after the challenge was issued. The response is not only based on the transmitted data but also guards against the substitution of data and guarantees the liveliness of the signal. In a nutshell, the responder utility can be explained as follows- let's say you have a given pseudorandom sequence from the server and then what the responder does is it calculates the respective pixel value of the fractioned subband and transmits the response along with the image. Now the pixel values are the numeric strings concomitant with the respective floating string, that I mentioned. On the receipt of the pixel value, the server verifies the pixel value of the image (by the time it gets to the server it has been magnified 10000 times). Another merit of this, any function could be used and each sensor can use a different function. It not only prevents the replay attacks but also increases the accuracy multiple folds. To put it in a simpler way, it's like arranging a complex jigsaw puzzle only that the impossible solution is evident to a select few (the designers). There is no overlap between the False Acceptance Rate and the False Rejection Rate. The Database is transiently online in this case and lesser the transmission over the internet the more safe it is. There is an independent allocation of the data akin to the storage CMOS (Complementary Metal Oxide Semiconductor) chips and the data is retrieved only when required.

RFID sequencing, yes that is a threat. Last year a couple of undergrads here at MIT showed how to utilize it in the sequencing of the magnetic cards used for transit systems. I, somehow don't want to touch that as of now.

I like the concept but I am very dubious about the usage of the HUffman Encoder. I mean, in what capacity are you going to use it? Have you ever tried a working model, if you have then has it worked? I am not sure about this and may be you should think it over. Don't get mad, just a suggestion.

What's so dubious? Well, Huffman encoder is strictly for the purposes of encryption. We did have a working model and it did work. Besides, what are we going to use to for? Not for the generation of the codes or the signals emanating from it but for the sole purpose of restructure. Yea, I realize that to begin with it may seem an ancillary approach to the whole thing but if you look at it from the intended point of view its application can not be left unaccounted for.

Now that we are on the Cyber Security and ensuring that data transfer is secure and intact, how about an open forum discussion on the issues of Intellectual Property and its limitations as outlined by the Government's MTA (Material Transfer Agreement) Protocol. There have been numerous moments when as researchers and scientists have had to face the problem arising from Intellectual Property laws and regulations. I want to hear all about it.

screw the MTA and the related paraphernalia associated with IP. Damn it man, just talk to her. This is strange in many ways- you are waiting to get a sign from her and on the other hand she wants to hear from you first. At the end you guys end up torturing yourself.

Listen up hoodlums, Nov. 17, marks one year of parto/separato of Jasmine Kamboj, MD and Jyoti Ballabh. I don't care when they start buzzing each other. But the only people getting harmed in this solitude are them. We all know how hopeless Jyoti has been. I have read Jasmine's mails and correspondences, her plight seems no better. From our end you guys get 2 more days to reopen the tracts of communication. There are girls in McCormick and Baker who want to write to Jasmine and I won't shudder from giving them her email id.

Jasmine, I know you read this. I should have mailed you what I am going to write but I want those 100+ interested parties to know this too. Between February 2009 and August 2009, Jyoti was awarded the conditional derived citizenship of the United States; the condition being he can never step into the Indian soil again. You may be aware that he has been awarded the faculty position at an Institute this side of the Charles. He stays in Beacon Street, across from the State House. Just come to Boston. Plzzzzzzzz.
