Abstract: Aiming at the frequent issues of resume forgery and resume leakage in the current society, a multiple resume protection and verification scheme based on blockchain and cryptographic accumulator is proposed. The decentralized characteristics of blockchain technology are used to reduce 1hoods and improve the authenticity of resumes. The high efficiency and encryption features of cryptographic accumulators are used to reduce the amount of stored data and the risk of privacy exposure. The multiple resume structure reduces the data access volume of the verifier, and users can selectively disclose their resumes and hide their resumes autonomously. After analysis and comparison, this scheme is verified to have high performance, low space-time consumption and privacy protection ability.
Key words: blockchain; cryptographic accumulator; multiple resumes; resume privacy; privacy protection

浙江省關(guān)于就業(yè)市場求職失信行為及其影響因素研究[1]中表示,有63.7%的被訪者表示對簡歷做過修飾,或編造過簡歷。大部分情況下簡歷造假對個人和企業(yè)帶來的影響都是非常大的。通常企業(yè)對求職者做背景調(diào)查(簡稱背調(diào)),一般采用如下方式:比如A企業(yè)需要核實候選人B的履歷信息,就需要委托第三方機構(gòu)充當(dāng)中心角色向C企業(yè)核實并返回調(diào)查報告[2]。背調(diào)過程中會有多方介入,同時簡歷數(shù)據(jù)還存在于中心化服務(wù)器中,各個中心化機構(gòu)之間標(biāo)準(zhǔn)的不一致也會導(dǎo)致形成數(shù)據(jù)孤島[3]。驗證簡歷真實性所消耗的成本以及中心化機構(gòu)的存在,都讓簡歷造假有了發(fā)揮的空間。2018年,F(xiàn)acebook遭遇了一場丑聞,該公司被曝光允許數(shù)據(jù)分析公司劍橋分析公司(Cambridge Analytica)非法獲取了8700萬用戶的數(shù)據(jù)[4],造成嚴重影響。……
