Abstract: With the proliferation of digital tool and content, it is becoming easier for adversaries to copy and modify digital content without detection or control by a content owner. Computing systems are provided to detects client-side data mutations. Responsive to a request to access the content data from a client device, a server compiles data that includes the content data, a mark and executable instructions for detecting data mutations, and sends this data to the client device. The client device then, based on the received instructions, stores the local environment properties relating to playing or viewing the content data, incorporates the mark with the content data, and allows the content data to be played or viewed or accessed. The client device also conducts checks in relation to the content data, the marker, and the local environment properties. If a data mutation is detected, the client device initiates an alert protocol.

Abstract: A film festival may play hundreds of films. Managing the variances in technical requirements for the film data to accommodate different screens and projectors, transferring the film data, and the coordinating digital communication from potentially hundreds of filmmakers may be technically challenging. A server system is provided to manage the transfer of the digital film data, the scheduling and assignment of film data with specific projector devices, and to validate the film data. The server system also provides graphical user interfaces (GUIs) to the film festival organizer to manage a print ticket process and the scheduling process, and GUIs to a filmmaker to facilitate transferring of the film data.
