Abstract
Systems and methods for controlling the transmission of data in a computer network; specifically, systems and methods related to preventing the transmission of compromised data. In one embodiment, a web server is configured to transmit requested data to a remote client through a computer network, such as the Internet. The web server includes a conventional computing system, including a processor and random access memory, and a non-volatile storage medium for storing the requested data. A software-defined process is executed by the computing system, whereby the software-defined process and the computing system cooperate to receive a request from a remote client for the requested data; determine whether the requested data has been compromised; and prevent the transmission of the requested data to the remote client if the data is compromised. Various techniques are disclosed for determining whether the requested data has been compromised, such as through comparison of a digital signature associated with the requested data to a control signature, which can be unique to the requested data or predefined for all data. Alternatively, or in addition to a comparison of signatures, the reques…
