Abstract: A method for linking user identifiers. The method includes receiving, by a linking server and from a company server, a first data structure comprising entries. Each entry comprising a user tag, a first hashed user information, and a second hashed user information. The method includes receiving, by a linking server and from a partner server, a second data structure comprising entries. Each entry comprising a bridge tag, a first hashed bridge information, and a second hashed bridge information. The method includes retrieving, by the linking server and from the first data structure, a first entry of the entries and retrieving, by the linking server and from the second data structure, a first entry of the entries. The method includes linking the user tag of the first entry of the first data structure to the bridge tag of the first entry of the second data structure to generate a first linkage.

Abstract: Systems and methods for a multiple value packing scheme for homomorphic encryption are described, including at a server, generating a plurality of encrypted payloads, each having a plurality of data values; and at a client, receiving each of the encrypted payloads having the plurality of data values; and multiplying one or more of the data values of one of the encrypted payloads by one or more other data values in one or more of the other encrypted payloads, to generate a product that represents the summation of data values corresponding to the multiplied one or more data values of the encrypted payloads and the one or more of the other data values in the one or more other encrypted payloads.

Abstract: An encrypted resource is stored in association with an access control list. A request to retrieve the resource is received. The wrapped key and the authentication credentials are sent, from the application server system, to a key server system. An unencrypted version of the resource encryption key is received from the key server system if the key server system determines that the authentication credentials correspond to a user in the group of users identified by the group identifier. The stored encrypted resource is decrypted using the received unencrypted version of the resource encryption key to generate an unencrypted version of the resource. The unencrypted version of the resource is sent, from the application server system, to the client application.
Abstract translation: 与访问控制列表相关联地存储加密资源。 接收到检索资源的请求。 包裹的密钥和认证凭证从应用服务器系统发送到密钥服务器系统。 如果密钥服务器系统确定认证凭证对应于由组标识符标识的用户组中的用户，则从密钥服务器系统接收到资源加密密钥的未加密版本。 存储的加密资源使用所接收的未加密版本的资源加密密钥进行解密，以生成资源的未加密版本。 将资源的未加密版本从应用服务器系统发送到客户端应用程序。

Abstract: Processing a query, includes, at a client, receiving a user-generated query having a plurality of recognizable terms, securing the user-generated query to generate an encrypted query, so that the plurality of recognizable terms generated by the user-generated query cannot be determined by a server, transmitting the encrypted query to the server, to perform the query on encrypted data comprising a mix of regular data and secure data previously provided by the client, wherein at least one of selection criteria of the query and identifies of selected records of the query result cannot be determined by the server, and interpreting a result of the query provided by the server, and providing an output of the query to the user having the plurality of recognizable terms.

Abstract: This document describes methods and systems by which a data storage service migrates a volume of stored data from an unencrypted format to an encrypted format while still permitting user access to the data. The encryption process uses migration markers to identify records that have undergone the encryption process. When migration is complete, the service removes the migration markers and retains the encrypted data in a data storage facility.
Abstract translation: 本文档描述了数据存储服务将一系列存储数据从未加密格式迁移到加密格式的方法和系统，同时仍允许用户访问数据。 加密过程使用迁移标记来识别经过加密过程的记录。 迁移完成后，服务将删除迁移标记，并将加密数据保留在数据存储设备中。
