Carbon emission data calling method and device based on ring signature and computer equipment

The invention relates to a carbon emission data calling method and device based on a ring signature and computer equipment. The method comprises the following steps: acquiring target carbon emission data submitted by each target carbon emission subject; adopting a ring signature technology to generate a ring signature corresponding to each target carbon emission data; and uploading each ring signature to a block chain, so that a query party in the block chain obtains target carbon emission data corresponding to each carbon emission subject according to each ring signature. By adopting the method, the submission of the carbon data can be completed on the premise of not leaking sensitive information, and the authenticity and integrity of the carbon data are ensured. 本申请涉及一种基于环签名的碳排放数据调取方法、装置和计算机设备。所述方法包括：获取各目标碳排放主体提交的目标碳排放数据；采用环签名技术，生成各目标碳排放数据对应的环签名；将各环签名上传至区块链，以供区块链中的查询方根据各环签名获取各碳排放主体对应的目标碳排放数据。采用本方法能够在不泄露敏感信息的前提下，完成碳数据的提交，并确保碳数据的真实性和完整性。
