A computer-implemented method includes identifying a plurality of protected pieces from a conversation. The computer-implemented method further includes generating one or more confidence scores for each protected piece, wherein a confidence score is a degree of associativity between a protected piece and a type of sensitive information. The computer-implemented method further includes determining that the protected piece is associated with the type of sensitive information. The computer-implemented method further includes determining a type of protection action for each protected piece in the plurality of protected pieces. The computer-implemented method further includes performing the type of protection action for each protected piece in the plurality of protected pieces to form a modified conversation that is devoid of the sensitive information. A corresponding computer system and computer program product are also disclosed.

A method of securely transmitting data comprising (1) obtaining an unencrypted data stream comprising a first sequence of values, (2) segmenting a first portion of the first sequence of values into an original first word having a word-length equal to a first variable, (3) segmenting a second portion of the first sequence of values into an original second word having a word-length equal to a second variable different than the first variable, (4) inserting random values at predetermined locations in the original first and second words to generate modified first and second words, the modified first and second words having a word-length equal to a third variable different than the first and second variables, and (5) combining the modified first and second words into a second sequence of values defining an encrypted data stream.

Various embodiments of the teachings herein include methods and systems for providing a speech-based service for the control of room control elements in buildings. Speech instructions are received by means of an audio device. The audio device is configured to analyze the received speech instructions, to convert them into corresponding operating commands for room control elements for the control of, in particular, HVAC devices (e.g. field devices) in a building and to pass them on to the corresponding room control elements. Before the receipt of the speech instructions by the audio device, the identity of the sender (user) of the speech instructions is anonymized by means of an anonymization service.

A method includes providing a plurality of variables and a variable. The variables differ from each other. The variables differ from the variable. The further method includes providing a lookup table indexing a plurality of characters via a plurality of values based on a first numeral system, converting a message into a first sequence of values based on the table, converting the first sequence into a second sequence of values based on a second numeral system different from the first system and according to a preset format, combining the second sequence into a single sequence via removing the format, generating a first plurality of subsequences from the single sequence based on segmentation of the sequence via alternating the variables, converting the first subsequences into a second plurality of subsequences such that each of the second subsequences is sized according to the variable, and transmitting the second subsequences.

The method includes a first encryption step of encrypting each of a plurality of data streams to obtain a respective encrypted data stream, a mapping step of mapping the plurality of encrypted data streams obtained in the first encryption step to a plurality of transmission streams for transmission via the optical transmission units, wherein the transmission streams and optical transmission units are in a one-to-one relationship, and wherein each transmission stream is mapped to by at least two of the plurality of encrypted data streams. The method further includes a second encryption step of encrypting each of the plurality of transmission streams to obtain a respective encrypted transmission stream, and a transmission step of transmitting each of the plurality of encrypted transmission streams obtained in the second encryption step via a respective optical transmission unit.

A bus communicates bits in parallel between a transmitter and receiver. A selected set of bits has its bits scrambled. Scrambling the bits includes assigning two or more bits of the selected set of bits to atypical lanes of the bus. By scrambling the bits, the order in which the bits of the selected set of bits are ready by a processer are obscured. The set of bits is transmitted to the receiver with one or more delays. The delays are on one or more of the lanes of the bus. The delays indicate the order of the bits. The receiver is configured to use the delays to identify the order of the bits and unscramble the set of bits.
