Abstract: Aspects of the subject disclosure may include, for example, a non-transitory, machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations including receiving a call; selecting a next carrier to handoff the call; generating a call data record (CDR) for the handoff to the next carrier; encrypting the CDR using a call encryption key, thereby creating an encrypted CDR; encrypting the encrypted CDR using a committee encryption key, thereby creating a double encrypted CDR; recording the double encrypted CDR to a blockchain; and sending the call encryption key to the next carrier. Other embodiments are disclosed.

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.

Abstract: In embodiments of the disclosed technology, indexes, such as inverted indexes, are updated only as necessary to guarantee answer precision within predefined thresholds which are determined with little cost in comparison to the updates of the indexes themselves. With the present technology, a batch of daily updates can be processed in a matter of minutes, rather than a few hours for rebuilding an index, and a query may be answered with assurances that the results are accurate or within a threshold of accuracy.

Abstract: Aspects of the subject disclosure may include, for example, embodiments include receiving first user-generated input from a recruiter device. The recruiter device is associated with a manager of a group. Further embodiments include generating a first smart contract between an applicant and the manager according to the first user-generated input. The generating of the first smart contract comprises generating the first smart contract on a blockchain. Additional embodiments can include providing the applicant access to the group according to the first smart contract, receiving second user-generated input from the recruiter device, and generating a second smart contract between a record keeper and the manager according to the second user-generated input. The generating of the second smart contract comprises generating the second smart contract on the blockchain. Also, embodiments can include providing the record keeper access to the group according to the second smart contract. Other embodiments are disclosed.

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.

Abstract: Content is secured in a database. One or more columns in challenge tables are identified, and values from the challenge tables are retrieved. A database query may execute in response to a match between the values from the challenge tables and query data. However, if the query data fails to match the values from the challenge tables, execution of the database query may be disallowed.

Abstract translation: 公开了一种用于在动态馈送环境中提供对数据质量的连续监视的系统。 特别地，该系统利用进料检测工具来检测从进料元数据中检测到的数据收集异常和基于文件内容检测的数据测量异常。 为了这样做，饲料检查工具可以在多个聚集间隔中聚合数据馈送和相关联的元数据馈送。 一旦数据馈送和元数据馈送被聚合，馈送检查工具可以通过利用不同长度的滑动窗口中的聚合馈送的历史数据为基线模型馈送生成基线统计模型。 然后，通过将聚合的进料与基准模型进料进行比较，进料检测工具可以通过多个监测时间延迟来识别数据异常值。 然后可以生成并发布基于所识别的数据异常值的数据质量提要。
