  • Patent number: 11088827
    Abstract: Concepts and technologies disclosed herein are directed to location-based blockchain. A localized corroborator system can receive, from a user device, an initiation message including a public key, and in response, can generate and send the random session identifier to the user device. The system can receive, from the user device, a signed session identifier including the random session identifier signed by the user device using a private key. The system can check a time that elapsed between sending the random session identifier to the user device and receiving the signed session identifier from the user device. The system can verify authenticity of the signed session identifier using the public key. In response to the time being less than a pre-defined threshold, the system can issue a location certificate to the user device. The user device can utilize the location certificate to conduct a certified blockchain transaction in a blockchain.

  • Patent number: 10977147
    Abstract: A system for providing continuous monitoring of data quality in a dynamic feed environment is disclosed. In particular, the system utilizes a feed inspection tool to detect anomalies in data gathering detected from feed metadata and anomalies in data measurement detected based on file contents. In order to do so, the feed inspection tool may aggregate, for a plurality of aggregation intervals, data feeds and associated metadata feeds. Once the data feeds and metadata feeds are aggregated, the feed inspection tool may generate, for a baseline model feed, baseline statistical models by utilizing historical data of the aggregated feeds in sliding windows of different lengths. The feed inspection tool may then identify, for a plurality of monitoring time delays, data outliers by comparing the aggregated feeds with the baseline model feed. A data quality feed based on the data outliers identified may then be generated and published.
