What is Spectrum?
Spectrum is the software that allows broadcasters hide information inside ordinary images and videos using a technique called steganography which is the art of concealing data inside other media so it is invisible to the human eye. This hidden layer can contain either text (i.e. messages, links, or metadata) or other images, making it useful for interactive applications like augmented reality experiences.
​
Spectrum provides an intuitive graphical interface so both technical and non-technical users can work comfortably. Through simple controls, users can choose how the hidden information is embedded, select different modes and strength levels, and finetune the balance between image quality and data capacity. Spectrum handles the complexity of steganography behind the scenes, allowing users to focus on what information they want to hide, rather than how the hiding process works.
Graphical User Interface
Enter your device's IP aaddress if you want to embed it amongst the other hidden information in the cover image. The IP address is a unique numerical label assigned to each device on a network.
Enter any passphrase in this field if you want to password-protect your hidden data. Leave blank otherwise.
Experiment with the advanced options so that the outputted embedded image shows less or more visible markers, or is more robust to distortion. See the user manual for more details.
