    • Processes are described for provision of privacy-sensitive sample analysis results to a sample provider. The sample provider generates a cryptographic commitment encoding a secret value, r, and a sample identifier, s, associated with a sample container. The sample provider provides the commitment to an analysis provider in association with the sample container containing a sample for analysis. The analysis provider analyzes the sample to obtain a set of analysis results corresponding to the sample identifier, s, and generates a cryptographic pre-credential, σ′, corresponding to the sample identifier, s. The pre-credential, σ′, encodes the set of analysis results and the commitment. Completion of the pre-credential, σ′, requires knowledge of the secret value, r, in the commitment. In response to cryptographic proof of knowledge by the sample provider of at least the secret value, r, in the commitment encoded in the pre-credential, σ′, corresponding to the sample identifier, s, the analysis provider supplies the pre-credential, σ′, to the sample provider. The sample provider then completes the pre-credential, σ′ using the secret value, r, to obtain a cryptographic credential, σ, encoding the set of analysis results.
    • 描述了为样本提供者提供隐私敏感的样本分析结果的过程。 样本提供者生成编码与样本容器相关联的秘密值r和样本标识符s的加密承诺。 样品提供者提供与分析提供者的关联,包含样品用于分析的样品容器。 分析提供者分析样本以获得与样本标识符s相对应的一组分析结果,并且生成与样本标识符对应的加密预凭证&sgr;'。 预认证“&sgr”编码了一组分析结果和承诺。 完成预先认证的&sgr;'需要知道秘密价值,r,在承诺。 响应于样本提供者的知识的加密证明至少在预凭证中编码的承诺中的秘密值r对应于样本标识符s,分析提供者提供预凭证 ,&sgr;'提供给示例提供者。 样本提供商然后完成预凭证&sgr;'使用秘密值r获得加密凭证&sgr,编码分析结果集。
