Abstract: Secure communication in a geographic incident area is disclosed. Computer-implemented methods are also disclosed, one of which is for restricting access to a resource and includes generating a key and splitting it into N key parts (where N is an integer greater than two). The method also includes encrypting the N key parts. The method also includes transmitting, over a network, to a device: the N encrypted key parts; and identifying information for N secret objects expected to be visible within the area. Each of the N encrypted key parts is decryptable based on at least one video analytics-discernable object attribute for each respective secret object of the N secret objects. The method also includes allowing an additional entity to access the resource only by presentation of a complete key formed from decrypted versions of less than all of the N key parts.
