<h1>什么是 WeIdentity？<a class="headerlink" href="#weidentity" title="永久链接至标题">¶</a></h1>
<p>WeIdentity是一套分布式多中心的技术解决方案，可承载实体对象（人或者物）的现实身份与链上身份的可信映射、以及实现实体对象之间安全的访问授权与数据交换。WeIdentity由微众银行自主研发并完全开源，秉承公众联盟链整合资源、交换价值、服务公众的理念，致力于成为链接多个垂直行业领域的分布式商业基础设施，促进泛行业、跨机构、跨地域间的身份认证和数据合作。</p>
<div class="section" id="id1">
<h2>模块介绍<a class="headerlink" href="#id1" title="永久链接至标题">¶</a></h2>
<p>WeIdentity目前主要包含两大模块：WeIdentity DID以及WeIdentity Credential。</p>
<div class="section" id="weidentity-did">
<h3>分布式身份标识 (WeIdentity DID)<a class="headerlink" href="#weidentity-did" title="永久链接至标题">¶</a></h3>
<p>传统方式中，用户的注册和身份管理完全依赖于单一中心的注册机构；随着分布式账本技术（例如区块链）的出现，分布式多中心的身份注册、标识和管理成为可能。
WeIdentity DID模块在<a class="reference external" href="https://fisco-bcos-documentation.readthedocs.io/zh_CN/latest/">FISCO-BCOS区块链底层平台</a>上实现了一套符合<a class="reference external" href="https://w3c-ccg.github.io/did-spec/">W3C DID规范</a>的分布式多中心的身份标识协议，使实体（人或物）的现实身份实现了链上的身份标识；同时，WeIdentity DID给与Entity（人或者物）直接拥有和控制自己身份ID的能力。</p>
<p>WeIdentity DID秉承以下设计理念：</p>

<div class="section" id="weidentity-credential">
<h3>可验证数字凭证 (WeIdentity Credential)<a class="headerlink" href="#weidentity-credential" title="永久链接至标题">¶</a></h3>
<p>现实世界中存在着各种各样用于描述实体身份、实体间关系的数据，如身份证、行驶证、存款证明、处方、毕业证、房产证、信用报告等。WeIdentity Credential提供了一整套基于<a class="reference external" href="https://w3c.github.io/vc-data-model/">W3C VC规范</a>的解决方案，旨在对这一类数据进行标准化、电子化，生成可验证、可交换的「凭证」（Credential），支持对凭证的属性进行选择性披露，及生成链上存证（Evidence）。</p>
<p>WeIdentity支持认证机构自行注册标准化凭证模板，共同丰富公众联盟链的生态。</p>
