The provenance information records the life cycle of the object and explains how it came to be in its current form.The provenance information can evaluate the reliability of data information and determine the credibility of data information,so the provenance in various fields has been widely studied in recent years,especially in the field of computer.And major breakthrough has been achieved in the field of provenance.However,the provenance information can play the important role based on the reliability of itself.So the research on security provenance is more important,being the basis of the provenance system.This paper selected the PROV-DM as the basis of research of the securing provenance model.1.A thorough discussion of data provenance model based on W3C PROV has been put forward.This paper introduced the PROV-DM in the W3C PROV family and analyzed the structure of each model.Meanwhile,this paper studied the relationship between each component,dissecting the realization mechanism of PROV extension structure.2.In order to realize the safety of the provenance,this paper established the security model by increasing the security nodes.The components of safety model has been described.The relationship between each node has been established.Regarding the realize of the security relationship,this paper focused on the integrity verification plan of W3C PROV.3.In view of the security access control,this paper put forward the security access control model based on W3C PROV.This model control the process of basic data using the data provenance,help to achieve the additional function not in those traditional access control model.This access control model based on dependency in the strategy specification and management reflect the simplicity and effectiveness.
