Secure data verification technique
A technique for the secure exchange and verification of data between multiple entities that use compatible business management systems utilizes serializable data transfer objects to transfer business data over a secure communication path. A conversion algorithm transforms a subset of the business data contained within the transfer objects, and the resulting data string is compared to data strings from other objects that are related to the transaction and which were transformed by the same conversion algorithm. If the data strings are not identical, a discrepancy exists. Serializable objects link all data objects relating to a given business transaction. An interface allows users to view and manage data contained in data objects, including discrepancies between compared objects. |

Reciprocal channel sounding reference signal allocation and configuration
Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations.
