This paper aims at showing a conceptual approach for security and traceability of shared information in the process of transportation of dangerous goods. Concerning the transport of dangerous goods, the process generates particular information, which is necessary to share with the stakeholders involved in this process. This information is considered sensitive, because it may contain the timestamp of movement of goods, information related to the goods, contractual business details, etc., and unauthorized parties should not access them. At any level, the process should remain transparent between stakeholders', with immutable properties on data sharing and the whole process should be auditable. We examine a general procedure for contractual issues for transportation of dangerous goods between stakeholders and its conceptual implementation by blockchain based on smart contracts.
