Aspects of the disclosure relate to multicomputer processing and dissemination of data files. A computing platform having at least one processor, a memory, and a communication interface may search one or more social media platforms for unauthorized dissemination of a data file. The computing platform may correlate a unique identifying feature(s) of the disseminated data file to that of a copy of the data file previously distributed to a linked user account. The computing platform may transmit, via the communication interface, to an administrative computing device, an unauthorized dissemination report which, when processed by the administrative computing device causes a notification to be displayed on the administrative computing device. The notification may identify the linked user account associated with the unauthorized dissemination, the name, content, or general nature of the data file, and/or the social media platform(s) on which the data file was discovered.
