Do you know any open source/free software C++ libraries to manipulate images in these formats: .jpg .gif .png .bmp ? The more formats it supports, the better. I am implementing a free program in C++ which hides a text file into one or more images, using steganography. I am working under Unix. Thanks for any help in advance ...
So, to simplify my life I want to be able to append from 1 to 7 additional characters on the end of some jpg images my program is processing*. These are dummy padding (fillers, etc - probably all 0x00) just to make the file size a multiple of 8 bytes for block encryption. Having tried this out with a few programs, it appears they are f...
I wish to put some text on a page and hide some data in that text. Does anybody know of any methods / patterns that have been used in the past to solve this problem? Example: I have the following text: "The cat sat on the dog and was happy." I also have the number 123. I want to hide this number in that sentence such that the sentence ...
I'm interested on the field, for now just hobby-like interest. So, I was wondering if you guys knew about good sources on such field. I will google some and probably post it also as an answer, on the meanwhile, you might add neat sources that you're aware of. EDIT: I found this here at SO: [1] http://stackoverflow.com/questions/27827/wh...
Hi. I'm currently in the process of writing a steganography application with QT. I am trying to hide my message bits in the least significant bit of the blue colour of the pixel From debugging I can tell that this section is working as it should. However after hiding my bits in the message I then save the image and then reopen it. Thi...
I would like to add some custom data to an image the user generates in my app, no more than 1kb tops. I could probably hide the data in the image, but I want to do this in a way that will resist resizing but not deliberate deletion of EXIF tags (say, for privacy reasons). Is this possible using the current public SDK 3.0? ...
How can I write some information inside a photo file like jpg or gif without destroying the image? and of course without showing it on the photo since the whole idea is to send information in the file of photo undetected by anyone (to provide security/privacy to some extent)! ...
This is an idea I have been thinking about, but I do not quite know how to solve it. I would like to know if any solutions like this exists out there, or if you guys have any idea how this could be implemented. Steganography Steganography is basically the art of hiding messages. In modern days we do this digitally by e.g. modifying the...
I'm trying to open a file to bytes, convert it to a string, modify some data (think Steganography) and convert the file back to bytes and save it as a jpeg. So far, everything I've tried has corrupted the file in converting it to a string. I've tried converting it to a 64-bit string, but of course that's a bit hard to modify the data in ...
Hi Community... I will appreciate efforts if some one can point me to some library which can be used for Video Watermarking. It would be better if it is open source. If ready made library is not available than links to informative article will also be good help. ...
Hi! I was wondering how can someone use python to encrypt text into an image. ...
I'm wondering - is there a steganography solution for digital images which is resistant to image manipulations? With "manipulations" I mean the most standard operations - recompressing JPEGs (or even changing file formats entirely), cropping and scaling. The application of this method would naturally be for image copyright protection. I...
Somewhere I found out steganography .. the way of storing or hiding information within another information.. at times certain images are also used to hide the information.. Can i get an example or any thing further to know more about how this is implemented... or if at all is it possible to use this in php ...
I want to add some text such as "Manula", to the image using Stenography and want to save it. And also i want to retrieve it again. I want to made this project using C#. Can anyone send me the C# code for this programm. Thanks.. ...
Hello, can anyone tell me if you know to be a problem with Bitmap and steganography for WM 6? I am working on a project and i have to hide a digital signature in a bitmap. The algorithm works perfect, as in untill i have the image on the memory the bitmap contains the modified bytes. But after i save the image (Bitmap.Save()) and I reo...
I am trying to write data stored in a binary file using turbo C++. But it shows me an error could not find an match for ostream::write(long *, unsigned int) I want to write a 4 byte long data into that file. When i tries to write data using char pointer. It runs successfully. But i want to store large value i.e. eg. 2454545454 Which ...
new_img = convert(img, text); (img, text) = convert_back(new_img); Can someone illustrate with a built-in image of MATALB? ...
I have made a steganography program to encrypt/Decrypt some text under image audio and video. I used image as bmp(54 byte header) file, audio as wav(44 byte header) file and video as avi(56 byte header) file formats. When I tries to encrypt text under all these file then it gets encrypted successfully and are also getting decrypted co...
Hi, I'm working on Steganography application. I need to hide a message inside an image file and secure it with a password, with not much difference in the file size. I am using Least Significant Bit algorithm and could do it successfully with BMP files but it does not work with JPEG, PNG or TIFF files. Does this algorithm work with these...
What are the basic and simpliest steganography algorithms and methods? I mean the steganography applied to images. How does simple program that hides data to images work? What are the main techniques used? How does the program recognize the encrypted message in image without the source image? ...
