Assignee: INTUIT INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 16:
17. A system comprising:
a processor;
a memory;
a host application stored in the memory and which executes on the processor;
an intermediary application stored in the memory and which executes on the processor;
the host application configured for:
establishing a multimedia stream with a guest client;

the intermediary application configured for:
receiving, after a host client establishes a multimedia stream with the guest client, host data from the host application;
updating a state machine using the host data;
receiving guest data from a guest application executing on the guest client and updating the state machine using the guest data;
propagating transaction data between the host application and the guest application, wherein the transaction data comprises the host data and the guest data;
presenting, together with the multimedia stream, at least some of the transaction data in both a first overlay presented by the host application and a second overlay presented by the guest application, wherein:
the first overlay and the second overlay are displayed over the multimedia stream,
the transaction data further comprises a numerical value from the transaction data of a transaction,
the numerical value is presented in both the first overlay and the second overlay, and
the transaction transfers the numerical value from a first data record to a second data record;

the host application further configured for:
presenting the guest data with the multimedia stream on the host client;

the intermediary application further configured for:
generating provider data responsive to updating the state machine with the host data and the guest data,
sending the provider data to the guest client, wherein the provider data is presented with the multimedia stream by the guest application on the guest client; and
storing an update to the state machine in a block of a hash chain, the block comprising a payload and a hash value, the hash value generated by hashing the payload and a previous hash value from a previous block from the hash chain.
