Steganography

Hi all,

Are there any knowledgeable people who would be able to help with a survey for my Bachelor’s? I would like you to analyse two PDF files and tell if you’re able to detect secret data presence. If yes, which tool/method you used to detect it. Thanks.

hi,

Maybe you could share those pdf files by providing a link to it ?
then we’ll see what we can do

Thanks for the reply.

First container and stego-object:

Second container and stego-object:
http://s000.tinyupload.com/?file_id=06514255788490958196

Please try to detect the presence of hidden data without using container file and tell if it’s possible.

what do you study and what is your survey about ?

I study computer science. The survey is about ability to detect a presence of embedded data for two different tools.

Two questions:
1. Are you able to detect a presence of the embedded data?
2. If yes, which method/tool you used?

Thanks.

ok, so i understand that it is an assignment that YOU must fulfill.
Not us

Not really, I have already analysed both stego-objects and highlighted their potential issues and how embedded data can be spotted. Now I am conducting a survey to obtain more data from other people to make conclusions on security and effectiveness.
