Description
Technical Field
The invention relates to the technical field of attendance systems, in particular to a block chain-based mobile attendance system and a block chain-based mobile attendance method.
Background
The existing check-in or attendance management modes are various: (1) adopting a traditional manual roster to sign in; (2) swiping a card by a attendance machine to sign in based on the RFIC/ID card; (3) the attendance machine identifies the attendance based on image identification and biological identification technologies such as fingerprints and human faces; (4) based on the GPS positioning technology, the mobile phone App software is used for checking in by a card.
The above-mentioned several kinds of check-in or attendance management, there are several following problems:
(1) the attendance checking method has the advantages that paper is adopted for signing, so that the efficiency is low, errors are easy to occur, statistics is not facilitated, data is easy to tamper, and the official trust of attendance checking is easy to be questioned;
(2) the adoption of the RFIC/ID card for signing in easily causes cheating behaviors such as card punching and the like;
(3) the equipment for signing in by adopting image recognition technologies such as fingerprints and human faces is high in cost, the equipment needs to be set in a fixed position and range, and the phenomenon of crowded queuing can occur when multiple people sign in at the same time;
(4) cheating behaviors such as GPS counterfeiting and the like easily occur when mobile phone App software is adopted for signing;
therefore, the existing attendance systems have certain defects, and if the attendance management of one enterprise has a leak, the staff dispute is easy to occur, and the existing attendance records are mostly mastered in the hands of background managers, so that the staff are difficult to be unclear about the attendance records of the staff, which is also one of the reasons for causing the labor dispute. Therefore, it is necessary to develop a reliable and tamper-proof attendance system to ensure that the attendance management is standard and effective.
The Blockchain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system. The blockchain is also a bottom-up innovation technology, is not directed at the reformation and the upgrade of a certain kind of application, but can generate subversive changes on all scenes related to data storage and information exchange processes, and the application prospect of the blockchain is expected by people.
The concept of smart contracts, proposed by nissabo in 1994, refers to contracts in which the terms are recorded in computer language instead of legal language, which defines in mathematical and programmed form a series of contracts' rights and obligations, which, once triggered by a particular transaction, can be automatically executed. Due to the lack of system and technical support at that time, the concept of intelligent contracts is not realized until the appearance of Etherns in 2013, so that the intelligent contracts can be executed in a trusted decentralized blockchain environment. The intelligent contract based on the block chain system not only has the advantages of cost efficiency and the like, but also can avoid the interference of malicious behaviors on the normal execution of the intelligent contract, has the characteristics of automation, decentralization and result determination, and cannot be stopped once being deployed on the block chain, so that the intelligent contract ensures that the processes of storage, reading, execution and the like are transparent, the record can be tracked and cannot be tampered.
Therefore, the attendance system is combined with the block chain technology, and the defects of the existing attendance system can be well overcome.
