Detecting unmanaged and unauthorized assets in an information technology network with a recurrent neural network that identifies anomalously-named assets
The present disclosure describes a system, method, and computer program for detecting unmanaged and unauthorized assets on an IT network by identifying anomalously-named assets. A recurrent neural network (RNN) is trained to identify patterns in asset names in a network. The RNN learns the character distribution patterns of the names of all observed assets in the training data, effectively capturing the hidden naming structures followed by a majority of assets on the network. The RNN is then used to identify assets with names that deviate from the hidden naming structures. Specifically, the RNN is used to measure the reconstruction errors of input asset name strings. Asset names with high reconstruction errors are anomalous since they cannot be explained by learned naming structures. After filtering for attributes or circumstances that mitigate risk, such assets are associated with a higher cybersecurity risk. |

System and method for authorized digital content distribution
A digital content distribution system uses a Digital Rights Management Controller that performs a set of arbitrary tests against the transfer request from one user to another such as user A to user B. Assuming these tests are successful, the DRM sends an encryption key to transferring user A. This encryption key E is taken from a table of encryption key/hash pairs which have been provided to the DRM Controller by an external authority such as the content rights holder. User A encrypts the content using they key provided by the DRM controller and then optionally calculates a hash over the encrypted form of the content E(X) and returns this value to the DRM Controller. On checking the returned hash against the hash from the table the DRM controller knows that user A does indeed have the digital content X in good condition. The DRM Controller then instructs both users A and B that the transfer may proceed. The encrypted form of the content E(X) is transferred from A to B. Once the content transfer has completed B ensures that the received content has been physically written to non-volatile storage (to account for crashes etc. during the next step). B then calculates a hash over the received content and returns this value to the DRM Controller. If this value matches the value previously given then the transfer has been successful and the DRM Controller updates whatever central records are appropriate, while also returning a decrypt key to B to allow it to decrypt the content. |

Methods and apparatus for signal transmission and reception in a wireless communication network
A broadcast signal transmission occurs concurrently with device-specific, directional transmissions but without substantially interfering with the directional transmissions, based on transmitting the broadcast signal in the null spaces of the directional transmissions. Specifically, transmission of the broadcast signal relies on beamforming precoder values formed from one or more orthonormal basis vectors for the null space of a channel estimate matrix representing the channels between a multi-element antenna array and the wireless devices targeted by the device-specific transmissions. The approach concentrates most of the broadcast signal energy for each subcarrier on a single antenna element for good broadcast-signal coverage while still yielding a beamforming solution that substantially avoids broadcast-signal interference at the devices targeted for directional transmission. |
