Concept for picture/video data streams allowing efficient reducibility or efficient random access
A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined subarea of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained.

Detecting a loop length change in a digital subscriber line
Presented is a method of detecting a loop length change in a digital subscriber line. An Uncalibrated Echo Response (UER) trace is obtained from the digital subscriber line by running a Single Ended Line Test (SELT). A historical (baseline) UER trace from the same line is retrieved. A line that has experienced a small change in loop length will have the same overall shape, but be compressed or stretched in the frequency domain. Thus, to detect such a change, a comparison between the two traces is made to determine if the difference between the two traces is less than a threshold but non-zero. Then a range of scale factors are applied in the frequency domain on either one of the traces, before determining which of the scale factors results in the lowest difference between the unscaled and scaled traces. The determined scale factor is above a certain threshold, then the line is determined to have had a loop length change. The value of the scale factor can be used to determine the amount the length has changed. |

A system and method for managing communications through adaptive switching between model-based and model-free approaches is disclosed. The system comprises a communication management server with a master AI agent that dynamically selects between model-based and model-free reinforcement learning techniques to process incoming communications.

Deceiving attackers accessing active directory data
Endpoints in a network execute a sensor module that intercepts commands. The sensor module compares a source of commands to a sanctioned list of applications received from a management server. If the source does not match a sanctioned application and the command is a write or delete command, the command is ignored and a simulated acknowledgment is sent. If the command is a read command, deception data is returned instead. In some embodiments, certain data is protected such that commands will be ignored or modified to refer to deception data where the source is not a sanctioned application. The source may be verified to be a sanctioned application by evaluating a certificate, hash, or path of the source.

Authentication of networked devices having low computational capacity
Authentication of a networked device with limited computational resources for secure communications over a network. Authentication of the device begins with the supplicant node transmitting a signed digital certificate with its authentication credentials to a proxy node. Upon verifying the certificate, the proxy node then authenticates the supplicant's credentials with an authentication server accessible over the network, acting as a proxy for the supplicant node. Typically, this verification includes decryption according to a public/private key scheme. Upon successful authentication, the authentication server creates a session key for the supplicant node and communicates it to the proxy node. The proxy node encrypts the session key with a symmetric key, and transmits the encrypted session key to the supplicant node which, after decryption, uses the session key for secure communications. In some embodiments, the authentication server encrypts the session key with the symmetric key. |

Noise shaping in digital-to-analog converters using randomizing encoders
Techniques for compensating high-speed digital-to-analog converters (DACs) for static mismatch are described. In ideal circumstances, the current sources of a DAC are identical to each other, leading to a frequency response presenting a relatively flat noise spectrum. In the presence of mismatch, however, the response creates unwanted spurious content, which can negatively affect the DAC's dynamic range. The techniques described herein involve randomized thermometric encoders. First, the direction in which a packet contracts or expands, depending on the value to be encoded, can be randomized. Second, pairs of values in a packet (and/or pairs of values outside the packet) can be swapped with one another in a randomized fashion. Third, the decision of whether to apply randomization or not can itself be randomized. By applying one or more of the randomization techniques described herein, the negative effects of switch timing offset and errors in DC linearity can be mitigated. |
