Stealth enhances the security of the digital twin by hiding information in regular content (such as images or text). This method preserves confidentiality and prevents data tampering, enabling secure communication between physical and digital devices. The Internet of Things (IoT) has brought about transformations such as automation and improved efficiency by connecting smart devices, but it also brings security challenges such as cyberattacks and privacy breaches. Due to their dispersion and diversity, IoT devices are easy targets for hackers who can steal data or take control of the systems. To counter these threats, methods such as encryption and steganography have been proposed. Combining these two methods can significantly increase information security in IoT. By integrating encryption (to protect data content) and steganography (to hide the existence of data), a higher level of security is created. This new approach improves the security of IoT devices and networks, allowing you to enjoy the benefits of this technology without facing serious threats. By implementing appropriate security solutions, you can reduce risks and build a secure future for the Internet of Things.
