1. A computerized method for authenticating an end point device participating in a media-based conference call, the method comprising: receiving, by a call processing module of a server computing device, a request to join a conference call between a plurality of end point devices, the request including credentials and attributes associated with a user of a first end point device, attributes associated with the first end point device, and a media stream associated with the first end point device; determining, at the call processing module, an identity of the user of the first end point device based upon the credentials and the attributes associated with the user; determining, at the call processing module, a level of conference call access based upon the attributes associated with the first end point device; retrieving, by the call processing module, a user profile based upon the identity of the user, the user profile including a set of permissions associated with authorization to participate in the conference call; generating, by the call processing module, a fingerprint associated with the request, the fingerprint comprising attributes derived from the user profile, the attributes associated with the end point device, and the requested conference call; analyzing, by the call processing module, the media stream using a matrix of authentication factors, wherein the authentication factors include at least two of: user-specific facial recognition attributes, user-specific audio recognition attributes, acoustic environment attributes, visual environment attributes, user gesture attributes, technical attributes of the end point device, and technical attributes of the media stream; determining, by the call processing module, an authentication score for the first end point device based upon the media stream analysis; and determining, by the call processing module, whether to connect the first end point device to the conference call, another media resource, or another user of a network or communication system based upon the authentication score and the fingerprint.
