A method of securing electronic computer files includes having a client-based application running in the background with a kernel extension and a communication channel over a network to a server. The client app. can intercept an interprocess communication for opening a file and then collect a swath of fingerprint information about the requesting process and the state of the computer. The fingerprint information is sent to the server, optionally through a Signal Protocol message hidden by steganography in an image. Based on the fingerprint information, the server sends a key and/or a command back, optionally through steganography, to the client. The file is then accessed and decrypted&#x2014;or accessed and not decrypted&#x2014;based on the server key and command. The command can include instructions to gather more data from the user or about the computer before allowing access.
