Secure sharing of bound information is enabled in client applications associated with a backend LOB service. Bound item IDs are assigned to newly created bound items by a client, the items synchronized with the LOB system, a correlation ID received in response to the synchronization, and the two IDs mapped. A reverse sequence of actions is performed when the LOB service creates the bound item. In response to an attempt by a client to exchange bound information, the item is placed in a pending state and allowed to be received by a receiver upon successful completion of data transfer and LOB system permission of the exchange passing the bound item ID and the correlation ID. If the LOB system rejects the exchange, the item is placed in an unbound state and the receiver not allowed to receive the bound information.
