【摘要】：地质资料的原始性是地质资料真实、可靠的前提,是地质资料汇交过程中急需解决的难题。本文基于目前我国保证地质资料原始性工作的发展历史与现状,利用可行时间戳、数字签名、MD5散列算法三种不同原始性保证技术,并对比这三种方法在汇交地质资料方面的优缺点。通过实践证明MD5散列算法在地质资料原始性检验方面具有操作简单、成本低、无负担等优势,但是由于地质资料保密性和数据格式复杂等原因,MD5散列算法尚需完善。
[Abstract]:The originality of geological data is the premise of the authenticity and reliability of geological data, and it is a difficult problem to be solved in the process of geological data gathering. Based on the development history and present situation of ensuring the originality of geological data in our country at present, this paper uses three different primitive guarantee techniques: feasible time stamp and digital signature MD5 hash algorithm. The merits and demerits of these three methods in confluence of geological data are compared. It is proved by practice that MD5 hashing algorithm has the advantages of simple operation, low cost, no burden and so on. However, due to the confidentiality of geological data and the complexity of data format, the MD5 hash algorithm needs to be improved.
