1. A computer-implemented method for a secure encryption generator based on user-specific electroencephalogram data, the method comprising executing on a computer processor the steps of: mapping each of a plurality of artificial neural network neuron elements to a first set of electroencephalogram data signals that are generated from scanning neural activity of a user while the user executes a current mental activity; training a first set of artificial neural network neuron element weighting factors to transform the first set of electroencephalogram data signals into a first weighted set of electroencephalogram data signals that are different from second weighted set of electroencephalogram data signals that are generated from scanning neural activity of the user while the user executes another activity that is different from the current mental activity, and from a third weighted set of electroencephalogram data signals that are generated from scanning neural activity of another user while the another user executes a mental activity that corresponds to the current mental activity; associating the trained first set of artificial neural network neuron element weighting factors with the first set of electroencephalogram data signals and with the current mental activity; defining a reproducible electroencephalogram encryption key that is unique to the user as a function of at least one of the trained first set of artificial neural network neuron element weighting factors and the first weighted set of electroencephalogram data signals; locking message content via a public key encryption process with the trained first set of artificial neural network neuron element weighting factors functioning as a public key; and sending the locked message to the user as a designated receiver.
