Abstract: An apparatus verifies hosted information associated with a user. The apparatus establishes, by the online host serving as a relying party system (RPS), a secure connection between the RPS and a user mobile-identification-credential device (UMD).

Abstract: Techniques are described for transaction-based read and write operations in a distributed system. In an embodiment, an authorization protocol overlaid onto a transaction to control access to each of the data pools. Using the techniques described herein, the DTRS provides authorization mechanism to ensure that the entity, which hosts the data pool, may only access the data set from an originating entity based at least upon the access rules of the originating entity set for the data set. Additionally, the DTRS's read/write transactions keep the data pools of the DTRS in synch with each other, so each data pool stores the same data sets as another data pool of the DTRS. When a data integrity service of an entity generates a new data entry from a user transaction with a client application, a new write request is generated for the DTRS to which the data integrity service belongs.
