协同签名系统

协同签名系统是由北京数字认证股份有限公司自主研发，是一款把移动终端(手机、平板电脑、专用手持智能终端等)作为签名设备，以用户移动终端数字身份为核心，为企事业单位内部应用提供简便易用、安全合规的移动身份认证和电子签名服务产品。协同签名系统由基础密码硬件平台、协同签名系统、协同签名 APP和协同签名系统安全密码模块（移动端 SDK）组成。产品基于协同签名技术，整个签名过程中没有用户完整私钥的出现，保证了签名私钥的安全性；每次签名都从业务系统服务端发起，保证了签名业务发起的安全可信性。

The Collaborative Signature System is independently developed by Beijing Digital Certification Co., Ltd. It is a product that takes mobile terminals (including mobile phones, tablets, dedicated handheld smart terminals, etc.) as signature devices, takes the user's mobile terminal digital identity as the core, and provides easy-to-use, secure and compliant mobile identity authentication and electronic signature service products for internal applications of enterprises and public institutions. The system consists of a basic cryptographic hardware platform, the core Collaborative Signature System, the Collaborative Signature APP, and the Secure Cryptographic Module (mobile SDK) of the system. Based on collaborative signature technology, the product ensures the security of the signature private key by never exposing the user's complete private key throughout the entire signature process; each signature is initiated by the business system server, which guarantees the security and credibility of the signature service initiation.
