What is the LSB technique in steganography?

The least significant bit (LSB) technique is a common method used in steganography to hide information within an image or audio file. In this technique, the least significant bit of each pixel in an image or each sample in an audio file is replaced with a bit of the secret message to be hidden. Since the LSB is the least significant bit, it is thought to have minimal impact on the overall quality of the image or audio file. Therefore, the changes made by this technique are often imperceptible to the human eye or ear. This makes it a popular choice for hiding information in plain sight.

steganogan: high capacity image steganography with gans
Steganogan is a technique for hiding secret information within an image using Generative Adversarial Networks (GANs). It is a type of steganography, which is the practice of concealing a message within another message.
The basic idea behind Steganogan is to use a GAN to generate a cover image that contains the secret message. The generator network in the GAN learns to create images that closely resemble the real images in the dataset, while the discriminator network learns to distinguish between real and fake images.
In Steganogan, the generator is trained on a dataset of cover images, while the discriminator is trained to distinguish between real images and images that have been modified to contain the secret message. The generator is then used to create a cover image that contains the secret message, which is hidden within the image in a way that is difficult to detect.
Steganogan has high capacity, which means it can hide a large amount of information within an image. It also has the advantage of being difficult to detect, as the hidden message is integrated into the cover image in a way that makes it difficult to distinguish from the original image.
Overall, Steganogan is a powerful technique for high capacity image steganography that uses GANs to create cover images that contain hidden messages.
Light Field Messaging with Deep Photographic Steganography
Light field messaging with deep photographic steganography is a method of hiding secret messages within digital images using deep learning techniques. This approach allows the messages to be embedded within the light field of the image, which is a representation of the flow of light in a scene. The hidden messages can then be extracted from the image using a deep neural network.
The use of deep photographic steganography allows for the creation of highly secure messages that are difficult to detect or decode by unauthorized parties. The technique involves embedding the message within the image in a way that is imperceptible to the human eye. The message is then encrypted using advanced algorithms to ensure its secrecy.
To extract the hidden message from the image, a deep neural network is used to analyze the light field and identify the specific pattern that represents the message. This process can be highly accurate, allowing for the secure transmission of sensitive information without fear of interception or detection.
Overall, light field messaging with deep photographic steganography is a powerful tool for secure communication that leverages the latest advances in deep learning and image processing technology. Its applications range from military and intelligence operations to corporate security and personal communication.
