  業務挑戰

  欺詐黑名單不足

  欺詐用戶、羊毛黨等在多家貸款平臺進行貸款欺詐,信貸機構的自有的欺詐黑名單數據有限,無法有效控制欺詐風險,導致信貸欺詐頻發,逾期率高,過于保守的放貸策略,影響放貸規模和業務增長

  共享聯盟構建困難

  基于數據安全的考慮,金融機構或者數據機構擔心數據泄露,機構間信任不足,無法快速構建互信聯盟,以防止多頭借貸等欺詐行為;對接多家機構,接口和數據格式不一致,開發成本高,構建可信共享平臺技術困難

  購買成本高

  需要同時接入多家數據提供商,存在重復購買數據,購買數據成本高;機構本身擁有部分黑名單數據,可基于自有黑名單信息與其它機構實現價值交換,以降低購買成本

  交易記錄追溯困難

  基于賣方市場的交易方式,調用賬單由賣家給出,實際調用次數等較難審計核驗,且審計核驗成本高,需要更加透明的數據調用記錄方式,使交易過程更加透明

  解決方案架構

  方案描述:

  基于區塊鏈的去中心化、唯一性、可溯源、不可篡改等特征,構筑互金機構間的聯合欺詐黑名單共享解決方案,來提升金融機構的放貸質量

  優勢:

  高效靈活

  支持多種高效共識算法,切換靈活,秒級共(5000TPS+),多角色節點和成員可動態加入/退出,采用容器化物理資源管理

  安全隱私保障

  完善的用戶、秘鑰、權限管理和隔離處理,多層加密保障,國密和同態加密等隱私處理,可靠的網絡安全基礎能力,保障運營安全無憂

  方案優勢

  可信共享

  通過基于區塊鏈的可信共享,實現黑名單共享,增加黑名單覆蓋能力,降低信貸欺詐,增加放貸規模

  創新交易模式

  通過積分等方式,實現自有黑名單與其它金融機構的黑名單進行價值交換

  安全加密

  基于分布式賬本、數據一次一密、實現安全的數據共享模式,保護用戶的隱私和商業機密,解決信息共享的安全與隱私問題

  易審計

  基于區塊鏈分布式賬本,防篡改、可追溯等能力,可實現交易記錄的追溯審計,使交易過程透明
