I recently came across an odd JPEG file: Resolution 400x600 and a filesize of 2.9 MB. I got suspicious and suspected that there is some additional information hidden. I tried some straight forward ...
I was reading up on FireEye and came across this NYTimes article detailing a Skype chat where an image was sent that was laden with malware: Quote: To gain access to information on the ...
spammimic.com offers a service that 'encrypts' your mail as 'spam', the rationale being that all mail services automatically filter out spam, and so if you're wanting to communicate with someone ...
I have written an application for Apple's iOS which embeds messages in JPEG files using steganography (see http://en.wikipedia.org/wiki/Steganography). For the purposes of this question lets assume ...
We are running an online-press media-library. On this site many brands are uploading images and track press users download and views per image. But some brand now want to add unique code in image so ...
Reading into "Operation Satyagraha", one would have to believe give all the resources used that the investigators had some reason to believe there was data to decrypt, even though in theory and in ...
I would like to use the best algorithm to hide 1024-bits inside an image. What is the best option to implement this? Is it by using Steganoraphy (i.e. LSB) or Digital water marking?
Are there any steganography algorithms which are capable of hiding a (optionally encrypted) text message within another innocuous text message? The scenario I envisage is that I would like to carry ...
I have seen some of the algorithms which are used to detect if a file is a stego-file or not, but all those algorithms check for specific patterns and are not universal. Maybe there are universal ...
I want to put some parts of my secret data into specific file with Steganography method. Is this method as safe as other encryption methods like RSA or SHA?
Suppose one wants to setup a cryptographic protocol in which 2 parties communicate using an encryption scheme that produces encrypted messages indistinguishable from random data (the desired property) ...
Assuming that I have an infected image containing a self-executing malicious code that targets my image viewer and executes when I open the file. Supposing also that my computer is completely clean ...
I am wondering if there is any system that would change source code trees in subtle from version control systems in ways that are hard to discover (i.e. whitespaces at the ends of lines, perhaps even ...
