Abstract  

[Objective] Research on how to use fixity check to ensure consistent fixity of digital object in preservation practices. [Methods] By reviewing standards and specifications, comparing fixity check tools, make a summary of current preservation projects and systems, and finally give a comprehensive analysis depending on preservation lifecycle. [Results] According to the actual needs, diversified methods and strategies of fixity check can be applied in the key nodes (ingest, AIP creation, storage, delivery) of the entire lifecycle management of digital preservation. And also do some reseach on how to store fixity information and how to build up fixity check. [Conclusions] This study may better help follow-up researchers and developers quickly understand and master the method and strategies of fixity check, help them to develop appropriate tools and strategies according to the actual need, so that preservation system can effectively ensure consistent fixity of digital object.
Key words： Fixity check      Digital preservation      Digital object
