Abstract
A system, apparatuses, and methods for device and network security are discussed herein. In an example, a security device for providing security to user-entered inputs includes a universal serial bus (“USB”) port configured to receive a connector of an input device and a USB connector configured to connect to a port of a user device. The apparatus also includes a processor configured to receive a string of characters from the input device that correspond to inputs made by a user into a web browser or application on the user device. The processor adds at least one security character to the string of characters to generate a watermark string, and transmits the watermark string to the user device. The processor is configured to format the at least one security character such that only the string of characters are displayed in the web browser or the application at the user device.
