Abstract: The present disclosure provides an approach for a blockchain system in which (a) data of past transactions can be removed from the storage of network nodes based on node permissions, and (b) in which data can be made invisible to users based on user-specific or group-specific permissions. The blockchain system stores cryptographic proofs of data on an immutable ledger. The data itself is maintained within the blockchain system such that it can be partially or fully removed, while maintaining the integrity of the ledger.

Abstract: Systems, methods, and devices are disclosed for authenticating a product. An internal component of a product is identified by identifying an intrinsic attribute of the internal component, where the intrinsic attribute is received at a time subsequent to independently storing the intrinsic attribute in a database. A match is determined between the intrinsic attribute and the stored intrinsic attribute. The product is confirmed to be authentic when the match is verified.

Abstract: In various implementations, a method of managing transactions in a distributed ledger is performed by a first network node that is configured to maintain a distributed ledger in coordination with a plurality of network nodes. In various implementations, the first network node includes a processor, a non-transitory memory, and a network interface.

In various implementations, the method include indicating whether there is an anomaly based on a function of the current transaction in relation to the characteristic value.

Abstract: Particular embodiments provide for attenuating one or more microphone signals in a teleconferencing system upon detecting a non-audible signal. A far end voice signal is received from a sound source. A non-audible signal is added to the far end voice signal to create a composite signal, which is provided to one or more speakers. The speakers output the composite signal and the non-audible signal are detected in the composite signal after the composite signal is received at one or more microphones. The non-audible signal allows an attenuator to attenuate a microphone signal including the composite signal from a particular microphone in response to the detected non-audible signal to reduce far end echo.

Abstract: A push-to-talk conference call is conducted over a packet switched network. Participants send a request and receive approval before being allowed to talk during the conference call. In one implementation, only one of the participants is enabled to transmit audio packets while other participants are only allowed to receive audio packets.

Abstract: Devices, softwares and methods are provided for redundantly encoding a data stream into frames for network transmission as packets. A main encoder encodes a data stream into main frames, while a redundant encoder encodes it into redundant frames. The redundant frames have a redundant-coding delay from the main frames that is adjustable to accommodate many different sets of network conditions.

Abstract: A content monitoring system applies policies to data transfers, and adapts the policies based on violations. Each policy includes a rule that detects violations and actions performed when the rule is violated. Policies may be adapted by, for example: enabling an inactive policy; modifying a parameter within a rule or an action; generating a new policy by combining a policy macro with the violating content block or with associated meta-data, for example, a user ID or IP address. An optional rolling buffer can be used to hold the most recent transfers, and newly adapted policies can be reapplied to the buffered content. Some content blocks are reassembled from a stream of terminal control protocol (TCP) packets that are transferred across a network barrier point. Other content blocks come from writes to removable media. Some content must be decoded, for example, a word processor file.

Abstract: Systems and methods are provided to facilitate efficient routing of unlicensed mobile access (UMA) communications. In one implementation, a method of providing a communication link between a first mobile station and a second mobile station through a customer premises equipment (CPE) device includes intercepting a call setup request provided by the first mobile station and received at a security gateway of the CPE device. An address associated with the second mobile station may be extracted from the call setup request and the address may be compared with a plurality of records maintained by the CPE device. A call setup request may be forwarded to the second mobile station if the address corresponds to at least one of the records. The first and second mobile stations may be in communication with the CPE device over a wireless local access network (WLAN) in accordance with an unlicensed mobile communication standard.
