    Abstract: In a fully homomorphic encryption scheme, a method is provided for performing a homomorphic operation on a data set by applying an encrypted operand supplied as a ciphertext. A data set containing ‘i’ library vectors, each with ‘j’ coefficients is subjected to a pivot operation such that each set of common ‘j’ coefficients is stored in respective library ciphertexts. A query ciphertext containing a query vector is then subjected to a homomorphic pivot operation to separate out its ‘j’ coefficients into respective pivoted query ciphertexts. A more efficient homomorphic computation can then be carried out between the ciphertexts of the pivoted forms of the query and library vectors so as to compute an encrypted set of vector differences between the query vector and each of the library vectors.

    Abstract: A method for viewing a plurality of encrypted code displayed within an integrated development environment with a pair of augmented reality (AR) glasses. A plurality of user login credentials submitted by a user utilizing the pair of AR glasses to access a plurality of encrypted code. The method may determine the user is authorized to access a portion of the plurality of encrypted code based on the received plurality of user login credentials. The method may further decrypt the portion based on determining the user is authorized to access the portion. The method may further include displaying the decrypted portion on a lens within the pair of AR glasses.

    Abstract: A method and/or computer program product assists in locating objects using a local physical device and one or more remote physical devices having image capture capability. A local physical device captures one or more reference images of an object, and shares identification metrics associated with one or more reference images of the object with one or more of the remote physical devices. One or more remote physical devices captures one or more images of an area in which the object may be located, and determines, using the identification metrics, whether any of the images captured includes the object. In response to a determination that any of the images captured includes the object, those images are stored and associated with the object. In response to the object being lost by a user, the local physical device reviews the stored images to determine a location of the lost object.

    Abstract: Version history tracking of functional components is provided. Whether a source of a functional component is known to a version history tracker is determined. If the source of the functional component is determined to be not known to the version history tracker, an automated analysis of content of the functional component is performed. If the source of the functional component is determined to be known to the version history tracker, a bifurcated version history hierarchy of the functional component is created using at least partial data transfer between at least two functional components irrespective of any metadata associated with either of the at least two functional components. A branched network of the version history for the functional component is produced. The branched network of the version history is based on at least one of the automated analysis and the bifurcated version history hierarchy.
