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.%The facticity and authenticity of the geological data is attributed to its aboriginality,which has become a difficult issue badly in need of solution.In this paper,based on the review of development history and present status for the work of ensuring the data aboriginality in China,three different aboriginality assurance technologies contains the credible time stamp,the digital signature and the MD5 hash algorithm had been used and compared with each other in the collection of geological date.Finally,the MD5 hash algorithm proved that has the advantage of simple to operation,economical and free of burden in verification of geological data aboriginality.But due to the confidentiality and the complexity of data formats for geological data such as reason,the MD5 hash algorithm still need to be further improved.
