Abstract: A data stream is stored in storage media. As part of the storage, the data stream is divided into a plurality of chunks. The plurality of chunks include a target chunk that is next to a first chunk in a file within the data stream. A determination is made that the target chunk matches an existing chunk stored in the storage media. In response to the determination, a first pointer to the existing stored chunk is created in file metadata for the file. Also in response to the determination, a second pointer to a first stored chunk that matches the first chunk is created in chunk metadata embedded with the existing stored chunk.

Abstract: A user-specific, electroencephalogram data-based secure encryption generator maps artificial neural network neuron elements to electroencephalogram data signals generated from scanning neural activity of a user while the user executes a mental activity. Weighting factors are trained to transform the electroencephalogram data signals into a first set of weighted signals that are different from weighted signals generated from scanning neural activity of the user while the user executes another, different activity, and from weighted signals generated from scanning neural activity of another user while executing a similar mental activity. The trained weighting factors are associated with the first set of electroencephalogram data signals and the current mental activity. Thus, a reproducible electroencephalogram encryption key is defined that is unique to the user as a function of one or both of the trained weighting factors and the first weighted set of electroencephalogram data signals.
