Abstract: A blockchain-based room inventory management system includes a property management system (PMS) module and an intermediate server system. The PMS module may be under a hotel's direct control. The intermediate server system communicates with at least one online travel agency (OTA) module and/or at least one booking engine using Ethereum-based smart contracts for confirming and processing a room reservation event. If the room reservation event is confirmed to be a successful transaction, the intermediate server system also updates the successful transaction into the PMS module and a blockchain formed by multiple node servers. The blockchain contains multiple blocks arranged in a chronological order for distinguishing successful transactions of different moments. In this way, each successful transaction is prevented from wrongly preceded by a later successful transaction. And the room inventory management system neutralizes an overbooking issue accordingly.

Abstract: A method for determining integrity of information of an object, comprises generating a first data corresponding to the information of the object and generating a first representative data corresponding to the first data; storing the first data to a database, and adding the first representative data into a first block of a blockchain; reading a second data from the database in response to a command for retrieving the first data from the database; using the first block to indicate whether the second data is identical to the first data.
