Jessica Fridrich

Jessica Fridrich, associate professor, department of electrical and computer engineering, specializes in all aspects of information hiding in digital imagery, including watermarking for authentication and tamper detection, self-embedding, robust watermarking, steganography and steganalysis, forensic analysis of digital images (detection of forgeries), advanced image processing and encryption techniques.

Transcript:
Some of our discoveries are completely serendipitous, and I like to use this word because it completely describes what we did. We were actually developing techniques for a so-called lossless watermarking, and as a side product, a completely unexpected side byproduct. It was useful for detecting hidden data on images, and it sort of triggered an avalanche of papers in the field based on essentially the same idea being perfected by our peers.

Every imaging sensor has some really bad pixels that show up as bright dots in the images, so we thought this would be a good, unique fingerprint for them. But then we found out that the pixels are not just completely faulty, but they have a degree of correctness, how they respond to light. And it was my graduate student, Jan Lukas, who one day over the summer came up with this. "Now I see this stochastic pattern in the sensor, in the noise, and it sort of repeats, but not completely from image to image. Could we somehow use this for detecting?"

So what we are really shooting for is that we make this technology available to law enforcement. They do their job, independent verification and testing. We do all the bookkeeping, and this way, you can go and present the technology as an expert witness in the court.

Is it true that he has undergone sex change? someone told me that her real name is Jerro/Jiro (i do not its spelling) Fridrich.

[rubiks99]

Jiri Fridrich sex change is already a olong time ago too

[ILCAC3]

Jessica Fridrich, creator of Fridrich Method, congratulations! The whole world is using it.

[ceamean]

and they say blonds r stupid! ha

[MrSuperboiii]

I'm a grown azz man; I know a dude in a wig when I see one!

[GODGuardianOfDeath]

@CousinBrothersXD yes



[CousinBrothersXD]

so its a guy that had a sex change right otherwise im really confused

[ohseedeemunky]

@ceamean You got me. I laughed. :P

[ceamean]

@ohseedeemunky *munky ;o*

[ohseedeemunky]

@ceamean *And *are *Ha!

[ceamean]

@raetzer2303 ok, now that's just cruel.

[raetzer2303]

@ceamean well she was born as a male

[DaOblit]

thumbs up if u were looking at the windows xp screensaver.

[pokemon3211]

so what if the creator of the fridrich method had a sex change, who ever can make a method that is used worldwide by the best cuber(s), must be one brilliant person.
